32 Chimney Services. All Five Boroughs. One Call.
10 crews dispatching from Brooklyn — no subcontractors, no delays. From routine cleaning to emergency leak repair, our certified technicians handle every chimney and fireplace need NYC buildings have.
What Prime Chimney Does — and Where
Prime Chimney Sweep & Repair handles every chimney and fireplace service NYC buildings need — from one Brooklyn dispatch base.
We’re a New York City chimney company. That’s the whole focus. We don’t do roofing, HVAC, or general contracting on the side. We clean flues, inspect liners, repair masonry, service gas appliances, and respond to emergencies. Ten crews run simultaneously across all five boroughs. Every call reaches our team directly — not a call center, not a franchise operator.
We dispatch from 919 E. 29th St. in Brooklyn. That puts us in reach of Manhattan, Queens, the Bronx, and Staten Island without routing delays.
Our services cover 32 distinct chimney and fireplace needs. Routine cleaning. All three tiers of inspection under NFPA 211 — the national fire protection standard referenced by NYC fire marshals and co-op boards. Masonry repair and waterproofing. Gas appliance service. Emergency response, 24 hours a day.
Built for NYC Buildings, Not Suburban Driveways
NYC chimney work is different from anywhere else in the country — and the differences matter. Most national chimney guides assume a detached house with a single flue and roof access from the backyard. That’s not New York City.
A single chimney stack in a Brooklyn brownstone or a pre-war Manhattan building often contains two, three, or four separate chimney flues — the interior channels that move combustion gases out of the building. Each one may serve a different unit. Each may have been last inspected before the current owner moved in.
NYC buildings constructed before 1940 — pre-war building stock — were built with lime mortar and clay tile liners. Using the wrong mortar mix during repointing accelerates brick deterioration rather than stopping it. These aren’t edge cases here. They’re the baseline condition across most of Brooklyn, Queens, and upper Manhattan.
The NYC Department of Buildings (DOB) — the city agency that regulates structural chimney work, permits, and violation enforcement — adds a layer that suburban chimney work doesn’t have. We work inside that system daily.
When One Call Covers Everything From a Cleaning to a Crisis
One company handling 32 services means your chimney situation doesn’t fall between two vendors.
A call came in on a Saturday evening last February. A property manager in Crown Heights had a brownstone showing a ceiling stain near the fireplace — a brown ring spreading from the wall. No one had touched the chimney in years. She didn’t know if it was a roof issue or a chimney issue. She’d already had a roofer clear the flat roof as the source.
We dispatched a crew that evening. The tech accessed the rooftop and found the flashing on the party-wall side of the chimney — the side facing the adjacent building — had separated at the base. Water had been running behind it for at least one season. The crown had two hairline cracks that had opened from freeze-thaw cycling.
The tech applied a temporary flashing seal and an emergency crown coating that night. That stopped the water entry before the next rain system — which arrived Sunday morning. A full flashing reseat and crown replacement was scheduled and completed the following week.
That’s the value of one crew covering the full scope. The initial emergency stabilization, the follow-up masonry repair, and the waterproofing treatment that followed were all handled without the property manager coordinating between separate contractors.
No subcontracting. One number, one crew, one documented record from start to finish.
10 Crews. 24/7. No Subcontractors.
Operational scale matters when your chimney situation doesn’t wait for a weekday morning. A 10-crew operation means a post-storm Saturday doesn’t create a two-week backlog.
Simultaneous Dispatch
Multiple calls from different neighborhoods go out at the same time. You reach the same number whether you’re booking annual Tier 1 inspection in September or reporting active water intrusion after a storm.
Real 24/7 Response
Around-the-clock availability for urgent chimney failures — storm damage, active leaks, falling masonry. Not a message service. Not a next-morning callback.
Our Crews Only
Every technician working a job is part of our crew. Emergency calls are handled by the same people who do routine service — no third-party handoffs.
How We Approach Every Job — Regardless of Scope
Every visit follows the same standard: assess first, document what’s found, then work. Our 32 services organize into nine categories — each handled by the same crew that dispatches for emergencies.
Cleaning & Sweeping
Annual chimney cleaning, rotary sweeping, fireplace cleaning, and creosote removal (first, second, and third-degree glaze) — the flammable byproduct of wood combustion that’s the primary fire risk in wood-burning systems.
Inspection
NFPA 211 Tier 1 visual inspection, Tier 2 camera scan with written report, and Tier 3 invasive structural inspection. Gas fireplace inspection. Chimney leak diagnostics with written source identification.
Masonry & Waterproofing
Mortar repair and repointing. Efflorescence removal. Vapor-permeable waterproofing. Spalling brick repair — individual unit replacement through partial chimney face rebuilds. Crown repair, smoke chamber parging.
Components & Hardware
Chimney cap installation (single-flue and multi-flue). Chase cover repair. Damper repair and replacement — throat dampers and top-mount cable systems. Gas log installation. Fireplace installation.
Gas Appliance Service
Component-level gas fireplace repair — pilot, thermocouple, thermopile, igniter, gas valve. Gas fireplace inspection. Gas log installation. Chimney draft analysis.
Odor Diagnosis & Sealing
Fireplace odor removal — diagnosis by odor type. Chimney odor sealing with compound applied to smoke chamber surfaces after cleaning.
Chimney Removal
Above-roofline removal. Full interior stack removal. DOB permit requirements identified before work begins so the scope is clear from the first visit.
Emergency Services
Emergency chimney leak repair. Emergency spalling brick repair. Emergency storm damage repair. All available 24/7 — same crews who handle routine service.
Wildlife Removal
Chimney animal removal. Bird nest removal — with federal nesting season compliance for protected species. Chimney wasp removal.
From the First Call to the Completed Visit
Every job follows a consistent sequence: call, dispatch, assess, document, work.
When You Call
You reach our team directly. The dispatcher asks three things: your borough and building type, the service you need or the symptom you’ve observed, and whether rooftop access coordination is required in your building. Co-op and condo buildings sometimes need management notification before a crew can access the roof. Knowing that upfront prevents a wasted trip.
What Happens at the Visit
The technician assesses the specific condition before any work begins. On a cleaning visit, that means identifying the degree of creosote present before selecting equipment. On a masonry repair visit, that means measuring crack depth and confirming mortar type before mixing anything. Every service visit produces a written record of what the tech found and what was done. That record is yours.
After the Work
If the visit reveals something that warrants a follow-up — a Tier 2 camera scan after a Tier 1 finds something worth a closer look, or a full crown replacement after emergency patching stabilizes a cracked surface — the tech explains it before leaving. The escalation is documented before the crew leaves. One crew handles the full sequence. You don’t re-explain the situation to a different person each time.

Ready to Schedule? Here's How to Reach Us
For routine scheduling — annual cleaning, inspection before the heating season, masonry assessment — call during the day and we’ll get you on the calendar. For emergencies — storm damage, active water intrusion, falling bricks, animal in the flue at midnight — call the same number. Someone answers around the clock.
Request Service
Replace this block with your form widget (Contact Form 7, WPForms, or Elementor Pro Form). For anything active or time-sensitive, call — the form is best for non-urgent service requests.
Questions We Get Before the First Appointment
Quick answers to the questions we hear most often. For anything specific to your building, just call — we’ll talk through it.
For active leaks, falling masonry, or storm damage, we dispatch the closest available crew immediately. With 10 crews running simultaneously across all five boroughs, most NYC addresses see a tech on site within 60 minutes during a true emergency. The same number is answered around the clock — not a message service, not a next-morning callback.
Yes. Every service visit — cleaning, inspection, or repair — produces a written record of what the technician found and what was done. That record is yours and can be shared with insurance carriers, co-op or condo boards, or future buyers during a home sale. Reports include photo documentation for inspections and any work involving structural masonry.
These are the three inspection levels defined by NFPA 211 — the national fire protection standard that NYC fire marshals and co-op boards reference. Tier 1 is a visual inspection of accessible chimney components, recommended annually. Tier 2 adds a video camera scan of the full flue and is required when ownership changes, after a chimney fire, or when system performance changes. Tier 3 is invasive — it requires opening walls or removing components to inspect concealed portions, and is used when Tiers 1 or 2 identify a hazard that can’t be fully assessed without exposure. We perform all three.
Yes. We work in co-op and condo buildings across Manhattan, Brooklyn, Queens, and the Bronx every week. Most of these buildings require management notification before rooftop access — we ask about this on the first call so the trip isn’t wasted. We can also coordinate directly with property managers and provide the certificate of insurance most boards require before work begins.
Yes. All Prime Chimney technicians are licensed and insured, and we hold the certifications required for chimney and masonry work in NYC. We can provide proof of insurance directly to building management, insurance carriers, or homeowners ahead of the appointment. For work that requires NYC Department of Buildings permits — like above-roofline removal or full chimney rebuilds — we handle the permitting before scheduling.
