Brooklyn Heights & DUMBO Dryer Vent Cleaning: Historic Landmarks, Converted Warehouses, and the Co-op Board Letter Reality

Brooklyn Heights and DUMBO sit next to each other on the map, separated by a footbridge, a BQE on-ramp, and roughly 180 years of building history. From a dryer-vent crew's perspective, they may as well be different cities.

In the Heights we are usually inside a 19th-century row house with a 35-foot vent run cut through three floors of original plaster, or in a pre-war co-op where the board requires an annual cleaning record on file. In DUMBO we are usually in a former cardboard-box factory turned loft, or in a 2014 Furman Street condo where the dryer is a ventless heat pump because the building code did not allow a duct penetration through the curtain wall.

We are Vent Pro NYC. Our crew has spent enough mornings on Joralemon Street and enough afternoons on Plymouth Street to know that the difference between a 45-minute job and a 3-hour job in these two neighborhoods is almost never the dryer itself. It is the building. This guide is the long version of what we tell every Heights or DUMBO homeowner who calls us asking what the job will actually entail.

If you want the shorter, borough-wide primer first, our complete Brooklyn guide covers the basics. This post assumes you have a Heights address or a DUMBO address and you want specifics.

Why Brooklyn Heights and DUMBO need a specialized approach

Three things make these two neighborhoods harder than, say, a 1990s townhouse in Sheepshead Bay.

First, both are landmark districts, in whole or in part. Brooklyn Heights was the first historic district designated by the NYC Landmarks Preservation Commission, in 1965. The boundaries cover roughly 50 blocks bounded by Court, Atlantic, the BQE, and the Promenade. DUMBO got its designation in 2007, covering most of the area between the Brooklyn and Manhattan bridges from the East River back to roughly York and Plymouth, plus a Vinegar Hill cluster. What that means in practice: anything visible from the street, including the exterior dryer vent cap and the wall around it, is subject to LPC review if it changes in appearance.

Second, both neighborhoods are co-op-dominant for multi-unit buildings. A co-op is not a landlord-tenant arrangement. It is a corporation that owns the building, and you, the shareholder, own a proprietary lease on the apartment plus shares in the corporation. The board has rules. Most Heights co-ops we work in require an annual dryer-vent cleaning record on file, a certificate of insurance from the contractor, and a window for performing the work that does not interfere with the freight elevator. We will get to all of that. If you are looking specifically at the co-op and condo angle, our co-op and condo deep-dive is the companion piece.

Third, DUMBO's building stock is mostly converted warehouses. The buildings were not designed for residential laundry. Vent paths were retrofitted, sometimes multiple times across multiple sub-conversions, and the existing ducts often run through shared mechanical shafts that handle multiple units. That makes diagnostics harder, not impossible, but harder. A bad duct in one unit can dump lint into a neighbor's unit if the shaft fan is undersized or the dampers are stuck. We have seen this.

The single most common mistake we see homeowners make in these two neighborhoods is hiring a vent cleaner based on price-per-job from outside Brooklyn. The job is not standardized here. A 28-foot pre-war run with two 90-degree bends and a roof termination is not the same job as a 12-foot straight run through a sidewall, and pricing it that way means somebody is going to cut corners. Usually it's the contractor showing up unprepared for what is actually behind the wall.

We will spend the rest of this guide walking through what we actually find, what the work involves, what we charge, and what your building is likely to require from us before we are allowed to start.

Brooklyn Heights buildings: 1830 to present

The Heights has, by some counts, the highest concentration of pre-Civil-War housing in New York City. Most of those buildings still have laundry in them, which means we still work in them.

Greek Revival and Italianate row houses (1830s-1860s)

These are the brick-and-brownstone row houses on Willow, Hicks, Garden Place, Sidney Place, Joralemon below Hicks, and the stretches of Henry, Clinton, and Pierrepont that escaped postwar tear-downs. From the sidewalk they read three to four stories plus a raised parlor floor over a garden level. From a vent crew's perspective they read: long vertical chase, original mortar joints, lath-and-plaster walls, and a laundry that is almost always in the garden-level kitchen or in a converted second-floor closet.

The typical run we encounter:

• Dryer on garden level: vent runs through the rear wall and exits through the back yard wall or up into a chase that exits at the parapet. Both are common. The yard-wall exit is shorter, usually 8 to 14 feet, but it often terminates into a vine-covered exterior cap that is half-blocked by ivy or a neighbor's planter.
• Dryer on parlor or second floor (modern owner moved it): vent runs vertically through a closet chase, often 20 to 32 feet up to a roof termination. These runs were retrofitted, sometimes in the 1980s, sometimes in 2014. The retrofitter's care varies wildly.

What makes these jobs slow: the chases are not straight. Original framing in a Heights brownstone has irregular joist bays, and the duct often has to bend around brick infill or a former chimney flue that was bricked up in 1962. We bring 50-foot rotary brush rod sections and a 4-inch brush, and we add 25 feet of camera cable for runs we cannot see straight through.

1920s pre-war co-op apartment buildings

The Heights has a cluster of pre-war elevator buildings, mostly along Pierrepont, Montague, Henry, and Clinton. Think Pierrepont House, the buildings around Pierrepont Plaza, the larger ones along Henry between Pierrepont and Joralemon. These were purpose-built rental buildings in the 1920s, then went co-op in the 1970s and 1980s.

Laundry in these buildings comes in three flavors, and we cover all three:

1. Building has a basement laundry room and no in-unit dryers. We do not service the basement room here (that is a commercial-laundry job and a different scope).
2. Building allowed in-unit washer-dryers as a renovation upgrade. Owner ran a vent line through an existing chimney flue or a dedicated chase. These are the most common pre-war runs we clean in the Heights, and the runs are typically 18 to 30 feet vertical.
3. Building does not allow vented dryers and the unit has a ventless heat-pump unit. More on these below.

Modernist mid-block apartment buildings (1950s-1970s)

A handful of mid-century buildings dot the Heights, mostly inside the landmark boundary as exceptions or non-contributing structures. These have shorter, more rational vent runs (often 12 to 18 feet) and were built with dedicated laundry chases. They are the easiest Heights buildings to service.

New-construction condos

Very few. The landmark designation effectively froze new construction inside the Heights district. There are a small number of conversions and ground-up builds at the edges, most notably along Pineapple Walk and the new development near Cadman Plaza. These behave like DUMBO condos for our purposes.

DUMBO buildings: factories first, condos second

DUMBO was a manufacturing district until roughly 1980. The neighborhood name itself is a developer-era acronym, but the buildings predate the name by a century in most cases.

Walentas-era warehouse conversions (1990s-2000s)

David Walentas bought up most of DUMBO in the late 1970s and 1980s and converted the warehouses to lofts starting in the 1990s. The buildings on Washington, Front, Water, Plymouth, and Jay south of York are mostly his conversions. They are typically:

• Heavy-timber post-and-beam construction with brick exterior walls (load-bearing brick, not curtain wall).
• 12-to-16-foot ceilings.
• Original wood floors over original joists, often with concrete sub-floors above and below in the upper conversions.
• Unit layouts that grew up around existing column grids and freight-elevator shafts.

These are great spaces to live in. They are challenging to vent. The original buildings had no residential laundry plumbing or venting. When a unit got a dryer, the duct had to be threaded through whatever path was available, which usually meant:

• A horizontal run across the ceiling to an exterior wall (sometimes 25 to 40 feet).
• A penetration through 12 to 18 inches of load-bearing brick.
• An exterior cap that may or may not have been LPC-reviewed.

We have cleaned runs in these buildings that turned out to terminate inside another wall cavity, which is a code violation and a fire risk and which we report in writing when we find it.

Empire Stores and the post-2010 condo boom

Empire Stores, the brick warehouses below the Brooklyn Bridge that became commercial and now sit beside Brooklyn Bridge Park, is mostly commercial. The residential building boom in DUMBO since roughly 2010 happened on Furman, Front, Plymouth, and along the bridge approach. These are mostly ground-up condos.

A key fact about post-2010 DUMBO condos: the building code, combined with curtain-wall construction and LPC review at the edges, made ducted clothes dryers impractical in most units. Penetrating a glass-and-aluminum curtain wall with a dryer duct is a thermal-bridging problem, a waterproofing problem, and an LPC problem all at once. Most of these buildings chose to require ventless heat-pump or condenser dryers instead.

Vinegar Hill edge

A small piece of the DUMBO landmark district stretches into Vinegar Hill, an older row-house cluster around Front and Hudson. These buildings behave more like the Brooklyn Heights row houses described above than like DUMBO lofts. We service them on the brownstone side of our pricing.

Why DUMBO heat-pump dryer prevalence matters

We need to spend a moment on heat-pump and condenser dryers because the DUMBO market is unusual.

A ventless dryer does not duct to the outside. It either condenses moisture into a tank or drain (condenser) or uses a heat-pump cycle that recirculates dry air through the load (heat pump). The unit has an internal lint filter, an internal evaporator coil, a condenser core, and in many models a secondary filter. None of these require an external duct. None of them require a roof cap or a sidewall cap.

What they do require is regular internal cleaning of the heat-exchanger fins and the secondary filter, plus periodic drain-line clearing. Manufacturers call for this every 6 to 12 months. In our experience, almost nobody does it, and the result is a dryer that takes 2.5 hours per load instead of 90 minutes, and a heat exchanger that eventually fails. The repair on a failed Bosch or Miele heat-pump heat exchanger is in the $600-$900 range. The 6-to-12-month maintenance, if you have us do it, is in the $185-$300 range. Math is straightforward.

If you have a heat-pump or condenser dryer in DUMBO (or anywhere else in Brooklyn, increasingly), our condenser and ventless heat-pump dryers post goes deeper on what the service actually entails. Short version: it is not a vent cleaning. It is a heat-exchanger and secondary-filter service, and we charge for it differently.

Buildings where we see ventless prevalence over 50% of units in DUMBO:

• Most Furman Street condos built after 2014.
• The Front Street curtain-wall condos.
• A subset of Walentas-era lofts where the original conversion did not include duct paths and subsequent owners installed ventless units rather than retrofit.

If you are not sure what kind of dryer you have, tell us the make and model when you book and we will tell you which service applies.

Co-op board letters in Brooklyn Heights

This section is the one we get the most questions about. The pattern is consistent enough across Heights co-ops that we can describe it as a general workflow.

What the board typically requires

Most Heights co-ops we work in want, before we are allowed to enter the building:

Item	Typical requirement	Notes
Certificate of Insurance	$1M to $2M general liability, building named as additional insured	We carry $2M and can name the building
Workers' compensation certificate	Statutory NY coverage	Standard, we provide
Liability coverage for elevator use	Some boards require it as a rider	Usually included in our policy
Scope-of-work description	Brief written description of what we will do	We email a one-page PDF on request
Cleaning record after the job	Date, unit, vent location, lint volume removed, before/after readings	We provide
Annual cleaning verification	Some buildings require an annual letter on file	We provide on letterhead

The COI in particular is non-negotiable in most pre-war Heights buildings. The building's insurer requires it because the building's policy excludes contractor liability. We carry a $2M general liability policy plus workers' comp. We can have the COI emailed to the managing agent within one business day of booking. Some buildings need 48 to 72 hours, so book a week ahead if you have a deadline.

The annual cleaning record

Several Heights co-ops adopted, post-2018, an annual dryer-vent cleaning requirement for all units with vented dryers. The board's logic is straightforward: NFPA 211 recommends annual cleaning, NYC has had dryer-vent-attributed fires in dense buildings, and the building's insurer wants the documentation. A few buildings make it part of the annual house-rules certification.

We provide a one-page cleaning record after every job, on letterhead, with:

• Date of service and unit number.
• Vent termination type and location (roof, sidewall, soffit, yard wall).
• Total run length measured.
• Lint volume removed (we collect and measure).
• Pre-cleaning and post-cleaning airflow readings (FPM and estimated CFM).
• Notes on duct condition, including any flex-duct sections we recommend replacing.

If you need the record formatted to match your specific board's template, send us the template when you book.

The COI request flow

The cleanest sequence for a Heights co-op job:

1. You book with us and tell us the building name, managing agent, and unit.
2. We email you a sample COI for review and forward the actual issued COI to your managing agent.
3. Managing agent confirms the COI is on file and clears us with the doorman/super.
4. We confirm the service window with you and the freight elevator window with the super.
5. We arrive, do the work, and leave you with the cleaning record before we go.

If you need help thinking through the broader co-op and condo process, the co-op and condo guide covers the procedural side in more depth.

Landmark Preservation Commission and exterior vents

Now to the part that confuses most homeowners. The LPC governs the appearance of landmark facades. It does not govern interior work, and it does not govern what you do inside your walls. It does govern the dryer-vent cap if the cap is visible from a public way.

What you cannot do without LPC approval

• Add a new exterior cap to a landmark facade where none existed before.
• Replace an existing cap with a unit of materially different appearance (e.g., from a low-profile bronze cap to a bright white plastic louver).
• Cut a new penetration through a landmark facade.

What you can do without LPC approval

• In-kind replacement of a deteriorated cap, matching material, finish, and dimension.
• Interior cleaning, brushing, and inspection of the vent.
• Replacement of interior duct components.

How this affects the work we do

In about 95% of Heights and DUMBO landmark-zone jobs, we are doing interior cleaning and inspection only. No LPC issue. We brush, vacuum, take readings, and leave.

In about 5% of jobs, the exterior cap is damaged. Common scenarios:

• A Hicks Street brownstone cap that has corroded over 25 years and is now leaking water into the wall cavity.
• A Joralemon Street roof cap that was crushed by a tree branch in a 2023 storm.
• A Plymouth Street DUMBO loft cap that was installed in 1998 without LPC review and now has a missing damper that is letting cold air in.

When this happens, we document the existing cap with photographs, take measurements, and give you a written recommendation. Then one of two paths:

1. In-kind replacement: we replace the cap with a matching unit. No LPC permit required. We can do this same-day if we have the right cap stocked, or within 5 to 10 business days if we need to order one.
2. Anything that changes the appearance: you (or your architect, or your managing agent) submits to LPC for review. We can provide the technical specifications they need for the application. We are not licensed to file LPC applications ourselves. We coordinate with whoever does.

We have done both routes. The in-kind replacement is straightforward and inexpensive (usually $185-$350 plus the cap itself). The LPC route takes 4 to 12 weeks for a routine certificate-of-no-effect application and longer for a permit. We schedule the cleaning around it and come back after the cap is approved if needed.

For the underlying code framework (building code, mechanical code, and how they interact with LPC requirements), see our NYC building code post.

What a typical job looks like in these two neighborhoods

We will walk through three representative jobs, because the variation is the point.

Job 1: Brownstone on Garden Place

We arrive at 9:00 a.m. at a 1842 Greek Revival on Garden Place, four floors, single-family since 2007. The dryer is in the garden-level kitchen, against the back wall. The vent runs through the back wall, into the rear yard, up a chase that was added during a 2010 renovation, and exits at the roof through a parapet cap.

Total measured run: 38 feet. Two 90-degree bends and one 45-degree bend.

What we do:

1. Set up drop cloths around the dryer. Disconnect the duct at the dryer. Inspect the transition hose. (This particular transition hose was a foil flex from 2010 with two compressed sections we recommend replacing.)
2. Take a pre-cleaning airflow reading at the dryer outlet. The reading is 280 FPM, which on a 4-inch duct calculates to roughly 245 CFM. The dryer is rated for 1.2 inches of water column static pressure, so anything under 300 CFM at 38 feet of run is a cleaning candidate.
3. Run rotary brushes from the dryer side up through the chase. We use a 4-inch brush on a counter-rotating rod, driven by a corded drill at 350 RPM. We never use a cordless drill on a long run because the torque drops off and the brush stalls in the duct.
4. Send a 25-foot inspection camera from the roof side down to confirm the run is clear and check the cap condition. The cap on this job had bird-nest debris from a starling pair that nested there in spring 2024. We removed the nest, replaced the damaged damper flap with an in-kind part we carry, and confirmed the cap is otherwise sound.
5. Vacuum the duct with a HEPA shop vac from both ends. We collect the lint and weigh it. This job: 14 ounces of dry lint. For a 38-foot run that has not been cleaned in 4 years, this is on the low side, which tells us the duct is in good condition with no kinks.
6. Reconnect the dryer with a new transition hose (semi-rigid aluminum, 6 feet). Test airflow at the dryer outlet. Post-cleaning reading: 470 FPM, roughly 410 CFM. That is a 67% improvement.
7. Run the dryer empty for 5 minutes to confirm normal operation.
8. Hand the homeowner a one-page cleaning record.

Total time: 2 hours 40 minutes. Pricing: $475, including the new transition hose and the damper flap. The cap itself was an in-kind repair, no LPC issue.

Job 2: Pre-war co-op on Pierrepont

A 1924 elevator building on Pierrepont. The unit is on the 7th floor. The board requires annual cleaning records. The COI was emailed to the managing agent 6 days ago. The freight elevator window is 10:00 a.m. to 12:00 p.m.

The dryer is stackable, in a hall closet. The vent runs through an interior chase up to the roof. Total run: 28 feet, mostly vertical, one 45-degree elbow.

What we do:

1. Check in with the doorman, confirm the COI is on file. Take the freight elevator up at 10:05 a.m.
2. Set up. Disconnect the dryer. (This dryer is a 24-inch stackable Bosch ducted unit, common in pre-war pre-pandemic renovations.)
3. Pre-cleaning reading: 220 FPM. Low.
4. Run rotary brushes up the chase. The chase is rectangular sheet metal, 4x6 inches, which is non-standard but acceptable. The brushes work fine in rectangular ducts as long as the diameter is right.
5. Camera inspection from the roof. The roof cap is a galvanized-steel low-profile cap from probably the 1990s renovation. Cap is sound, damper works, screen is intact.
6. Vacuum. Lint volume: 9 ounces. Normal for a 1-year cleaning interval on a stackable Bosch.
7. Reconnect, test, post-reading: 410 FPM. 86% improvement.
8. Provide the cleaning record to the homeowner. Email a copy to the managing agent for the building file.

Total time: 1 hour 45 minutes. Pricing: $325. The freight elevator window was honored. The doorman got a copy of the cleaning record for the building's file.

Job 3: DUMBO loft on Washington Street

A 4th-floor loft in a 1908 Walentas-converted warehouse on Washington Street. The conversion happened in 1998. The current owner bought the unit in 2019. The unit has a stackable ducted dryer in a small laundry closet near the kitchen.

The unit owner does not know where the duct exits. The 1998 conversion plans on file with the managing agent do not specify. There has been one prior cleaning, in 2021, by a different contractor who, per the homeowner's recollection, "looked at it for an hour and said they couldn't figure it out."

This is what we call the DUMBO loft "where does this even vent to" problem, and it gets its own section below.

The DUMBO loft "where does this even vent to" problem

Warehouse conversions in DUMBO went through multiple sub-conversion rounds. The original 1990s loft might have been a single 4,000 sf unit. By 2008 it was sub-divided into three units. By 2016 two of those units were combined again. Each sub-conversion added new walls, new duct runs, and sometimes new exterior penetrations. Old runs got drywalled over, sometimes still connected, sometimes capped, sometimes abandoned mid-chase.

When we get a call for a job like the Washington Street loft above, the diagnostic process is:

1. Inspect the dryer's connection point. Confirm the duct is connected and that the dryer is actually pulling through it. (We have seen ducts that go into the wall, terminate in the wall cavity 18 inches in, and have been dumping warm moist air into the wall for years. This is a serious problem and we report it.)
2. Send a borescope down the connected duct from the dryer side. Track distance and direction.
3. Identify the first elbow or junction. Photograph it. Continue.
4. If the duct exits the unit envelope into a shared shaft or chase, request access to the shaft from the building super or managing agent. This usually requires the engineer's drawings, if they exist.
5. If the duct cannot be traced and there is no exit point we can find, we recommend the homeowner switch to a ventless heat-pump dryer.

Real story, anonymized: a unit on Front Street where the duct ran 22 feet horizontally across the ceiling, up through a chase to the roof, and out through a cap that, when we traced it, did not exist. The duct had been capped at the parapet during a 2014 roof replacement and never reopened. The dryer had been venting into the parapet wall for nine years. We documented it, the homeowner had us remove and cap the abandoned duct, and they switched to a heat-pump dryer.

This is not a one-off. It happens in DUMBO often enough that we have a checklist for it.

Pricing

Pricing varies with run length, accessibility, and what we find on inspection. The ranges below are our typical billed totals for these neighborhoods, inclusive of brushing, vacuuming, inspection, airflow readings, transition-hose replacement when needed, and the cleaning record.

Building type	Typical price range	Typical time on site
Brooklyn Heights row house / brownstone	$375-$650	2-3 hours
Brooklyn Heights pre-war co-op	$250-$400	1.5-2.5 hours
Brooklyn Heights modernist mid-block	$225-$350	1-1.5 hours
DUMBO post-2010 condo (ducted)	$250-$425	1.5-2.5 hours
DUMBO Walentas loft	$325-$550	2-3.5 hours
Ventless heat-pump dryer service	$185-$300	1-1.5 hours
Vinegar Hill row house	$325-$525	2-3 hours

A few notes on what moves the price:

• Run length over 30 feet adds 10-20% because we need additional rod sections and more brush passes.
• Roof access (versus sidewall) usually adds 15-25% because of the time to set up safely on a Brooklyn Heights or DUMBO roof.
• A damaged transition hose adds $35-$75 for parts.
• A damaged exterior cap that we can replace in-kind adds $185-$350 for parts and labor.
• An LPC review situation does not add to our cleaning price, but the cap replacement waits for approval and is billed separately when we come back.

For a deeper breakdown of how Brooklyn dryer-vent cleaning is priced borough-wide, the cost breakdown post covers more building types.

If anyone in these neighborhoods is quoting you a flat $99 or $129 for a Heights row house or a DUMBO loft, ask them to send you their COI, their workers' comp certificate, and a sample cleaning record before they show up. Either they will not respond, or they will show up unprepared. The buildings here cannot be done at that price by anyone carrying real insurance.

Scheduling and access

The mechanics of getting into these buildings is its own skill.

Freight elevator booking

Most pre-war Heights co-ops and most DUMBO lofts and condos require freight-elevator booking for contractor access. The freight elevator is usually:

• Available weekdays between 9:00 a.m. and 4:00 p.m.
• Reserved by the unit owner through the managing agent or the super.
• Booked in 2-hour blocks.
• Closed on weekends in most buildings, with rare exceptions.

We can do the job in a single 2-hour block in most pre-war co-ops. Heights brownstones (where we are not using a freight elevator, just the front door) and most DUMBO condos have more flexibility but often require a doorman check-in.

COI ahead of time

Allow 3 to 5 business days for the COI to be issued, emailed to the managing agent, and accepted on file. Some managing agents are faster. Some larger property managers (FirstService, Halstead Property Management) have a portal that processes COIs in 24 hours. Some smaller agents take a week.

We email the COI to the unit owner and the managing agent simultaneously, and we follow up if we have not heard back from the managing agent within 48 hours. We do not bill until the job is done, so there is no urgency on your side until the job is on the calendar.

Weekday versus weekend

We service both. Weekend availability in Heights pre-war co-ops is limited to a handful of buildings that allow weekend contractor work. We can usually do DUMBO condos on Saturdays. Brownstones are wide open weekends. If you have flexibility, weekday mornings are usually the easiest to schedule on short notice.

Working with supers and managing agents

We have working relationships with most of the larger managing agents covering Heights and DUMBO buildings. If your building uses a smaller agent, we will introduce ourselves and email credentials directly. About 80% of jobs in these neighborhoods do not require any work on your end beyond confirming the freight elevator window with the super. About 20% require a board approval or some back-and-forth with the managing agent on the COI specifics, in which case we coordinate with you.

If you want a sense of how this contrasts with the lighter access requirements in, say, Williamsburg or Greenpoint, where the building stock is newer and the co-op share is smaller, our Williamsburg and Greenpoint post covers the differences.

FAQs

My Heights co-op requires an annual dryer-vent cleaning record. Do you provide that?

Yes. We provide a one-page cleaning record on letterhead after every job, with date, unit, vent details, lint volume, and pre/post airflow readings. We can email it directly to your managing agent or board, and we can format it to match your building's template if you send the template to us when you book.

Do you carry liability insurance for landmark buildings?

Yes. We carry $2M general liability and statutory NY workers' compensation. We have not had a claim in these neighborhoods. The landmark status of the building does not change our insurance requirements, but the buildings themselves often have stricter COI rules than non-landmark buildings, which we meet.

What is your COI limit?

$2M per occurrence and $4M aggregate on general liability. We can name your building or your managing agent as additional insured. If your board requires a higher limit, let us know and we can add a one-time excess endorsement for the job.

Can you handle a heat-pump-only dryer in a DUMBO condo?

Yes. We service ventless heat-pump and condenser dryers from Bosch, Miele, LG, Whirlpool, and Beko. The service is different from a ducted vent cleaning. We clean the heat-exchanger fins, the secondary filter, the lint screen housing, and the drain line if it is a self-condensing model. The service price range is $185-$300. See our heat-pump and condenser dryers post for the technical details.

What about a stackable washer-dryer combo in a 600 sf studio?

Common in DUMBO and the smaller Heights apartments. We service all the common ducted stackable models (Bosch 24-inch, GE Unitized, Whirlpool stackable) and most of the all-in-one washer-dryer combo units, ducted and ventless. Working in a small studio is mostly a logistics question of moving the unit out of its alcove far enough to disconnect the duct. We bring furniture sliders and we replace the unit exactly as we found it.

My DUMBO loft has a duct that nobody can find. What do you do?

We trace it. We send a borescope down the duct from the dryer side and track the path. If the duct exits into a shared shaft, we coordinate with the building super to get into the shaft. If the duct ends in a wall cavity or is otherwise abandoned, we document it in writing and recommend either re-ducting (if a viable path exists) or switching to a ventless dryer. We have done the diagnostic on a dozen-plus DUMBO lofts.

How often should we clean in these neighborhoods?

For ducted dryers, annually. The combination of long runs (especially in Heights brownstones and DUMBO lofts), older duct materials, and high usage in family households makes annual cleaning the right cadence. For ventless heat-pump dryers, every 6 to 12 months for the heat exchanger and secondary filter. For a borough-wide answer, see our how often to clean post.

Do you do exterior cap replacement on a landmark facade?

In-kind replacements, yes, with no LPC permit required. Anything that changes the cap's appearance from what was previously approved or grandfathered requires LPC review, which we do not file directly. We coordinate with your architect or managing agent and provide the technical specifications they need for the LPC application.

Will you write a letter for my insurance company?

Yes. If you need a cleaning verification letter for your homeowner's or renter's insurance, we provide one after every job. Some Heights insurers (Chubb, AIG Private Client) ask for annual cleaning verification on policies with high-value contents.

Can you service the building's basement laundry room?

That is a commercial-laundry-vent job and a different scope from in-unit service. We do some commercial work, but it is by separate quote. Have your building super or managing agent call us at (718) 541-5567 for a site visit.

What if I am renting and the landlord refuses to schedule cleaning?

Common question. In a Heights row house rental, this is between you and the landlord (usually the owner). In a Heights co-op rental, the unit owner (the shareholder) is responsible, but you can pay for the cleaning yourself if you want documentation for your renter's insurance. In a DUMBO condo rental, same: unit owner is the responsible party, but you can hire us as the occupant. We will email the cleaning record to whichever party you specify.

Do you work in Brooklyn Heights basements with shared laundry?

If the basement laundry serves a single unit (typical in a brownstone single-family) yes, that is a standard residential job. If it is a co-op or condo shared basement laundry, that is the commercial-laundry-vent scope mentioned above and is a separate quote.

Soft CTA

If you have a Brooklyn Heights brownstone, a Heights pre-war co-op, or a DUMBO loft or condo and you want a real conversation about what your dryer-vent situation actually involves, we are happy to walk through it with you. We work in these two neighborhoods most weeks of the year and we know the building stock by address.

Book online at /book and we will reach out to confirm the building, the access requirements, and the COI process. Or call us at (718) 541-5567 and we can talk through it directly.

We will not show up with a flat-rate quote and leave a cleaning record that does not match what your board wants. We will show up with the right insurance, the right paperwork, the right tools for a 38-foot Heights brownstone run or a Walentas-era loft, and a quiet morning of doing the work properly.

Vent Pro NYC. Brooklyn-based, Heights-experienced, DUMBO-experienced.
