Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Repair Across Brooklyn
Chimney repair in Brooklyn comes down to this: most of the chimneys we work on were built between 1890 and 1920, and they weren’t built for the way we heat homes today. A standard repointing job on a Brooklyn rowhouse chimney runs $400 – $900, a flashing repair typically lands between $350 and $750, and a full rebuild can run $3,000 – $7,000 depending on access and how much brick has to come down. If you’re seeing water stains, spalled brick, or a damper that won’t close, call Flint Chimney Sweep at (830) 251-4560. We’ll give you a written price before any work starts.
We dispatch crews into Brooklyn every week, from Greenpoint down to Bay Ridge and out through Flatbush and Canarsie. We know the rowhouse stock, the parapet walls, and the flat-roof access ladders that make chimney work here different from anywhere else. Brooklyn is dense. The chimneys are old. And the freeze-thaw cycle on brick near the East River and the harbor is relentless. That’s the job. We do it in writing, with a camera, during a Chimney Inspection - Brooklyn, so you see exactly what we see.
Key Takeaways:
- Most Brooklyn chimney repairs run $350 – $900 for repointing and flashing work; full rebuilds run higher.
- Every repair from Flint Chimney Sweep carries a written 365-Day Done Right Promise.
- You get camera inspection photos before you approve any repair. No guessing, no mystery.
- Written price before work starts, on every job, no exceptions.
Why Flint Chimney Sweep Is Brooklyn’s Preferred Chimney Repair Company
Brooklyn homeowners don’t put up with vague pricing, and neither do we. Flint Chimney Sweep has been part of the Garrison Partners family since 2002, and our Chimney Repair team operates under The Garrison Standard: a written price delivered before any work starts, a background-checked and uniformed technician on every call, and a written guarantee on every repair. That guarantee is the 365-Day Done Right Promise. If a covered repair fails within one full year of the service date, we return at no charge. No argument, no second invoice.
We answer the phone with a live person, 24 hours a day, seven days a week. When you call about a chimney issue in Brooklyn, you won’t sit through a voicemail tree. You’ll talk to someone who can schedule the job and tell you what to expect. That matters in a borough where a stuck damper or a leaking flashing cap can sit for weeks if you’re waiting on a callback. Our crews know the rowhouse layout of Carroll Gardens, the brownstone blocks of Park Slope, and the walk-up access issues in Williamsburg. We quote the job based on what the camera shows, not on what a salesperson hopes to sell you.
Chimney Repair Companies in Brooklyn
Brooklyn Chimney Repair companies fall into two camps: those that subcontract the work to whoever’s available, and those that send their own trained, uniformed technicians with the tools and materials on the truck. We’re the second kind. A typical chimney repair here means working on a shared party wall, or a flue that hasn’t been cleaned in a decade, or a crown that’s been cracked by forty Brooklyn winters. The job involves diagnosing the actual failure, not just the symptom. That’s why we run a camera up the flue on every repair call and send you the photo report. If a company won’t show you the inside of your chimney, walk away.
What We Do When You Call
You call, we schedule. The tech arrives inside the window we give you, in uniform, with a background check already on file. We assess the chimney, run the camera, and show you the photos. Then we hand you a written price. You approve it before a single tool comes off the truck. That’s the sequence, every time.
What Brooklyn Chimney Work Actually Costs
Repointing on a Brooklyn rowhouse chimney typically runs $400 – $900, depending on the amount of joint work and mortar removal. Flashing repair lands in the $350 – $750 range. A chimney cap replacement runs $200 – $450 for the cap plus install. If the crown is gone and the brick below it is spalled, a partial rebuild runs $1,500 – $3,000. Full rebuild from the roofline up runs $3,000 – $7,000. Those are the ranges we see in this borough. You’ll get your number in writing, flat, before we begin.
Chimney Masonry Repair in Brooklyn
Chimney Masonry Repair in Brooklyn is a different animal than in the suburbs. We’re not working on a freestanding chimney in a yard. We’re working on the top of a rowhouse, usually accessed from a flat roof or a parapet, where the chimney is shared with the building next door. The masonry failures we see most often are spalled brick faces, failed mortar joints, and crown deterioration. When water gets into the brick and freezes, it pops the face of the brick off. On a party wall, that damage can show up on the neighbor’s side first. That’s a Brooklyn-specific fact, and it changes how we diagnose.
Mortar Repointing and Tuckpointing
Repointing is removing the old, crumbled mortar from between the bricks and packing in fresh mortar that matches the original in strength and color. Tuckpointing is the finish work that makes the joints look sharp. On a 1905 rowhouse, using mortar that’s too hard for the brick is a real failure mode. Older brick is softer than modern brick, and the wrong mortar will crack the brick before the joint fails again. We match the mortar to the building, not to the bag on the shelf.
Spalling Brick and Crown Repair
Spalling is when the face of the brick breaks away, usually from trapped water freezing and expanding. Left alone, a spalled brick becomes a hole, and the hole becomes a leak path to the interior. The crown is the concrete cap on top of the chimney, and when it cracks, water runs down inside the masonry. We repair crowns with proper crown coat systems and replace bricks that have lost their structural face. On rowhouse chimneys, we always check the shared side.
Trusted Brands We Service in Brooklyn
We work with professional-grade chimney materials - including Gelco in Brooklyn - because a repair is only as good as what goes into the wall. On Brooklyn chimneys, we specify HeatShield for flue resurfacing where a liner can’t be pulled or is too tight to access. We use Olympia Chimney stainless caps and flashings, and Famco dampers when the old cast iron frame is rusted through. We keep common sizes and parts stocked for fast turnaround on Brooklyn jobs, which means less waiting on a second visit because a part had to be ordered. The material gets specified by the job, not by margin. That’s the rule.
Common Chimney Repair Problems We See in Brooklyn Homes
- Water at the crown and flashing on rowhouse parapets. Flat roofs and shared parapets route water in ways that test every seam. When the crown cracks or the flashing pulls loose at the sidewall, water runs down through the brick and freezes. By spring, the damper’s rusted and the brick face is spalled. It’s often mistaken for a flue problem, but the camera shows the real entry point.
- Third-degree creosote glaze from old coal grates converted to wood burning. A fireplace that started as a coal grate wasn’t designed for a wood fire’s exhaust temperatures. Years of burning unseasoned wood at low heat leaves a hard glaze in the flue that a standard brush can’t remove. This is the leading cause of chimney fires we see in Brooklyn.
- Party-wall flue defects showing symptoms next door. In attached rowhouses, the flue runs up the shared wall. A crack or missing mortar joint on one side of the wall can vent smoke or staining into the neighbor’s unit. The visible symptom shows up next door to the actual failure. That’s why we photograph everything and document the shared wall in our report.
- Rusted dampers and missing caps. The damper is the first thing to fail when water gets down the flue. On a Brooklyn chimney, a rusted damper usually means a crown or cap has been compromised for years. We replace the damper frame, but we also fix the water entry. Just changing the damper without stopping the water means you’ll do it again in three years.
Pricing for Chimney Repair in Brooklyn, NY
Here’s what you can expect to pay for chimney repair in Brooklyn, based on the work we do most often. Repointing runs $400 – $900. Flashing repair runs $350 – $750. Cap replacement runs $200 – $450 installed. A partial rebuild runs $1,500 – $3,000. A full rebuild from the roofline up runs $3,000 – $7,000. What moves the number up: roof access difficulty, how much brick has to come down, and whether we’re working on a shared party wall that requires coordination. No job is priced blind. We come out, run the camera, and hand you a written price. Call (830) 251-4560 and that’s exactly what happens.
Most Brooklyn rowhouses were built before modern chimney liners existed. The original flue was built for coal, and somewhere along the line, someone lined it for oil or gas. Or they didn’t, and that’s the problem. Our techs have to read layers of someone else’s work before touching anything, because what’s visible from the roof doesn’t tell you what’s happening inside the flue. The camera does.
We were called to a two-story brick rowhouse on Sackett Street in Carroll Gardens where the homeowner had water stains spreading down the party wall and a damper that stuck halfway. Our tech ran a Level 2 inspection with a camera and found the chimney crown cracked and flashing pulled loose at the sidewall, with first-degree creosote in the flue and a rusted damper frame. We replaced the crown, reseated the flashing, installed a new stainless cap, and reset the damper, then sent the photo report showing the before and after so the neighbor could see there was no shared-flue breach.

FAQs About Chimney Repair in Brooklyn
Yes, and here’s why: creosote builds up little by little, even with light use, and in a Brooklyn rowhouse chimney, small problems with the crown or flashing compound through freeze-thaw cycles every winter. An annual inspection catches a $400 flashing repair before it becomes a $4,000 rebuild. Flint Chimney Sweep includes the camera report with every inspection, so you see what we see. Call (830) 251-4560 to schedule one.
A Level 1 inspection is a visual check of the accessible parts of the chimney when nothing has changed about how you use it. A Level 2 inspection adds camera work inside the flue and is required when you buy or sell a home, after a chimney fire, or after a storm event. A Level 3 inspection involves opening up part of the building when a Level 2 finds something that needs a closer look. In Brooklyn, if you’ve never had the flue camera-inspected, you need a Level 2. Call us for a direct answer on your specific rowhouse.
We document everything first. The camera goes up the flue, and we photograph the shared wall, the flashing, the crown, and the interior. Then we tell you, in writing, whether the defect is in your section, the neighbor’s section, or the seam between them. If it’s a shared flue issue, we don’t guess. The photo report shows the exact location, and we can send that report to your neighbor so there’s no dispute about what’s wrong or who’s responsible for repairing it.
Third-degree creosote is a hard glaze, and a standard brush won’t remove it. In many cases, we can restore the flue using HeatShield, which is a resurfacing system applied directly to the existing flue walls. It’s not the same as a full reline, and it’s less disruptive and less expensive than a stainless liner in a tight rowhouse flue. Whether it’s HeatShield or a DuraFlex stainless liner comes down to what the camera shows. We’ll tell you plainly which one you need and what each costs, in writing. Call (830) 251-4560 for an assessment.
A lot of chimney work can wait. Small cracks in the crown that haven’t let water through, minor mortar erosion on the windward side, a stain that hasn’t spread, those can often be monitored and scheduled when the weather’s decent. What can’t wait: any sign of smoke in the living space, any evidence of a chimney fire (a loud roar, heavy smoke, visible flame from the top), or a flue breach that’s venting into the neighbor’s unit or your own walls. Carbon monoxide risk isn’t a scare tactic, it’s a measurement. If you smell smoke or see staining that’s growing, call us at (830) 251-4560 and we’ll get a tech out to look.
