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.

We’re Flint Chimney Sweep, part of the Garrison Partners family founded in 2002, and our crews work Manhattan neighborhoods from Inwood to the Financial District every week. If you’ve got a leak, a draft problem, or brickwork that’s starting to crumble, call (830) 251-4560 and a live person answers, day or night. You’ll get a written price before any tool comes off the truck, and every repair carries our 365-Day Done Right Promise in writing.
Why Flint Chimney Sweep Is Manhattan’s Preferred Chimney Repair Company
Manhattan homeowners don’t have time for chimney companies that no-show or change the price at the door. Our technicians arrive background-checked and in uniform, and the price you approve in writing is the price on the invoice, no exceptions. That’s the Garrison Standard, the same code every Garrison Partners location follows, and it’s why our Manhattan customers tend to call us again when they move or when a neighbor needs a recommendation.
We work in prewar co-ops, landmarked brownstones, and postwar high-rises alike. A chimney problem on the Upper West Side is a different animal than one in a 30-story Murray Hill tower, and our techs know the difference. Dispatch is coordinated from our New York City office, so scheduling for Manhattan is fast and direct, not routed through a call center in another state. You’ll never leave a voicemail when you call, and you’ll never wait until Monday for an answer.
Chimney Repair Companies in Manhattan
Chimney Repair Companies in Manhattan fall into two camps: the ones that quote low over the phone and the ones that put everything in writing before work begins. We’re the second kind. A proper chimney repair here isn’t a quick caulk-and-go job. It means evaluating the flue liner, the masonry, the flashing, and the damper as one connected system, because in Manhattan’s rowhouse stock, a “chimney” is often a shared party-wall structure where one flue serves multiple fireplaces across adjoining units.
When a Manhattan homeowner calls about a repair, we start with a camera inspection, not a guess. The photo report tells you exactly what’s wrong, what it costs to fix, and what can safely wait. Nothing gets recommended unless you can see the evidence yourself.
Liner and Flue Work
Flue relining, which means replacing the inner liner that channels smoke and exhaust safely out of the house, is one of the most common repairs we do in Manhattan brownstones. Original 19th-century flues were sized for coal, not modern wood or gas inserts, so creosote builds faster and third-degree glaze can’t be brushed out. HeatShield is often the right fix here: a cerfractory sealant that restores the flue without tearing out walls. In high-rises with factory-built metal liners, we’ll spec DuraFlex or Olympia Chimney components to match the existing system.
Flashing and Cap Repairs
Missing or undersized chimney caps are a chronic problem across Manhattan. Heavy rain and snowmelt pour straight into the flue, spalling the brick and rusting the damper from the inside out. We replace caps with Copperfield or Olympia products and re-flash the base with proper ice-and-water shield underneath, because Manhattan rooftops get hit with wind-driven rain that finds every gap.
Chimney Masonry Repair in Manhattan
Chimney Masonry Repair in Manhattan is as much about the building envelope as the fireplace itself. Decades of freeze-thaw cycles on exposed rooftop brickwork, compounded by the salt air and heavy rain that hits the island from all sides, mean spalling brick, cracked mortar joints, and shifted crowns are the rule, not the exception. We rebuild what’s failed and repoint what’s loose, working with mortar matched to the original so landmark reviews don’t get held up.
For a full masonry restoration on a typical Manhattan brownstone, homeowners should expect to spend $1,800 – $4,500. Smaller tuckpointing jobs can run $600 – $1,200. The written estimate you receive breaks out materials and labor line by line, so you know exactly what you’re paying for before the first brick is touched.
Tuckpointing and Repointing
Tuckpointing is the process of cutting out deteriorated mortar and packing fresh mortar into the joints. On Manhattan rowhouses with party walls, repointing isn’t cosmetic. Loose joints let water into the shared structure and can let heat or carbon monoxide migrate into the neighboring unit if the flue liner behind them is compromised. We do it right, not just where it’s visible from the street.
Crown and Cap Rebuilding
The chimney crown is the concrete slab that caps the top of the masonry and sheds water away from the flue. When crowns crack, water gets behind the brick and the damage accelerates fast. We pour new crowns with a proper overhang and drip edge, and we crown-coat with Gelco for waterproofing that holds up to Manhattan’s rooftop exposure.
Trusted Brands We Service in Manhattan
We stock and install professional-grade chimney components from Olympia Chimney, Famco, Copperfield, and DuraFlex, plus HeatShield for liner repair and Gelco for waterproofing. These aren’t brands you’ll find at a home center, and that’s the point. A Manhattan chimney repair that uses contractor-spec materials lasts longer and passes inspection the first time. Because we dispatch locally to Manhattan, we can get the right part the same week in most cases, without waiting on a distributor shipment from out of state. You’ll see the brand names in your written estimate, so you can verify the spec independently.
Common Chimney Repair Problems We See in Manhattan Homes
- Party-wall flue liner failure. In rowhouses and brownstones, chimneys are shared between units. A flue liner crack in one home can leak carbon monoxide or heat into the neighboring property, so we always inspect the full length of the flue, not just the firebox.
- Undersized flues from the coal era. Many 19th-century flues were built for coal fires. Modern wood or gas inserts burn differently, and undersized flues build third-degree creosote glaze fast. That glaze can’t be brushed out and requires chemical treatment or liner replacement.
- Water intrusion from missing caps and bad flashing. Manhattan’s heavy rain and snowmelt pour into uncapped flues, spalling brick and rusting damper assemblies. We see it from Harlem to Battery Park, especially on rooftops exposed to wind-driven rain.
- Cracked crowns and deteriorated mortar joints. Freeze-thaw cycles on Manhattan rooftops break down mortar and concrete over time. Tuckpointing and crown rebuilding stop the water at the top, before it gets behind the brick and into the house.

FAQs About Chimney Repair in Manhattan
An annual inspection is still the right call in Manhattan, even if you light a fire twice a year. The reason is water, not use. Manhattan’s heavy rain, snowmelt, and rooftop exposure can crack a crown or loosen flashing whether you burn or not, and a party-wall flue that shares structure with a neighboring unit can degrade from exterior moisture alone. A Level 1 inspection catches small problems before they become $4,000 rebuilds. Call (830) 251-4560 to schedule one.
First-degree creosote is a fine black dust that a standard brushing removes. Third-degree creosote is a hard, glossy glaze that forms when undersized coal-era flues burn modern wood or gas at the wrong temperatures. It cannot be brushed out. In a Manhattan brownstone with an original flue, third-degree glaze means a chemical treatment or a liner repair like HeatShield. Our camera inspection tells you which one you actually have, and the written estimate tells you what it costs to fix.
Yes. High-rises with factory-built metal chimney systems use different components than masonry flues, and we work with DuraFlex and Olympia Chimney parts to match the existing system. The repair usually means replacing damaged liner sections, anchor plates, or caps rather than rebuilding masonry. We’ll spec the correct components on the written estimate, and the 365-Day Done Right Promise applies exactly the same as it does on a brownstone.
Urgent means flue liner cracks that could leak carbon monoxide, water actively entering the house through flashing or crown damage, or loose masonry that could fall. None of those should wait. Repointing or crown coating that shows minor wear but no active leak can often be scheduled within the season. We were called to a brownstone on West 88th Street where a second-floor fireplace had a stubborn smoke problem. After a Level 2 inspection with camera, we found the smoke chamber was parged unevenly and the original flue liner had spalling mortar joints. We rebuilt the smoke chamber, installed a HeatShield liner repair, and reset the damper. The draft immediately improved and the owner could finally use the fireplace without the room filling with smoke. That was urgent. If your chimney is smoking or you smell anything unusual, call (830) 251-4560.
Yes. Every repair in Manhattan starts with a camera inspection, and you get a photo report showing exactly what’s damaged, where it is, and what the repair will involve. Nothing is recommended unless you can see the evidence yourself. That’s non-negotiable, and it’s the same Garrison Standard every Flint Chimney Sweep and Garrison Partners location follows. When you approve the written estimate, the price on that paper is the price you pay.
