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 Liner & Rebuild Across Greenpoint
A chimney liner and rebuild in Greenpoint typically runs $2,200 to $7,800 depending on flue height, liner material, and how much of the masonry crown or stack needs rebuilding. Wendell and his crew can usually have a camera down your flue within a few days of your call, and most liner replacements are completed in one or two visits. We know these buildings because we’ve been working on them since 1999. If you’re in a pre-war row house or tenement on Manhattan Avenue, Franklin Street, or anywhere between McCarren Park and the Newtown Creek edge, call (929) 822-6306 and we’ll give you an honest read on what the chimney actually needs.
Why Top Hat Chimney Is Greenpoint’s Preferred Chimney Liner & Rebuild Company
Greenpoint’s attached brick row houses and 3-6 story tenements are a different animal from anything else in Brooklyn. When your chimney shares a party wall with two neighbors and serves gas appliances across three floors, the job requires someone who knows how these original multi-flue stacks were laid in the 1890s and what happens when they fail. That’s our bread and butter. Ask anyone on your street. We’re the crew that has pulled more pigeon nests and collapsed clay tile out of sealed Victorian flues than we can count, and we’ll show you the camera footage before we recommend a single thing.
Local homeowners keep our number because we answer the phone, give a real arrival window, and the price we quote before work starts is the price on the invoice. No national outfit sending a stranger who changes the number at the door. Wendell puts his name on the work. You’ll run into him again on Saturday at the Greenmarket. The 90-Day Done Right Promise is in writing on every job: if it’s not right, one call brings us back at no charge.
Our Chimney Liner & Rebuild Services in Greenpoint
Stainless Steel Liner
A stainless steel liner is the right fix for the oversized clay-tile flues in most Greenpoint row houses. Your original chimney was sized for coal furnaces. The gas boiler venting into it now produces cooler, moisture-heavy exhaust that condenses inside that big Victorian flue, and that acidic condensation eats clay tile from the inside out. A properly sized stainless liner, typically DuraFlex or Olympia, solves the draft and the corrosion in one shot.
Flexible Liner
For the multi-flue chimney stacks on Greenpoint tenements with tight bends, offsets, or abandoned flues pressed against the live one, a flexible liner snakes through without disturbing the brickwork. It’s the practical choice when the flue is mostly sound but needs relining for a gas conversion or insert. We use product from brands we trust, and we’ll show you the spec sheet before anything goes in.
Liner Replacement
When the clay liner has spalled, shifted, or collapsed, the old sections have to come out before a new liner can go in. In Greenpoint row houses, we often find the old clay tile has been quietly crumbling for years, with debris wedged in the flue and water seeping into the party wall. Liner replacement stops the hidden damage and gets your gas appliances drafting correctly again.
Partial Rebuild
You don’t always need the whole chimney rebuilt. The top five to ten courses above the roof are what take the worst of Freeze thaw from East River and Newtown Creek moisture, and that’s where a partial rebuild of the stack and crown makes sense. On a shared chimney, the exposed upper section may be cracking while the lower flues are fine. We’ll rebuild what’s failed and leave what’s still solid, with photos and a plain-English explanation of exactly what we did and why.

Trusted Brands We Service in Greenpoint
We install and service liners from DuraFlex, HeatShield, Olympia Chimney, and Famco, and we keep common sizes and components stocked for Greenpoint jobs, which helps us turn around a liner replacement without waiting on a distributor. HeatShield is often the right spec for a Greenpoint fireplace flue that needs a ceramic resurfacing rather than a full metal liner. We’ll walk you through the difference and the price of each option, and then you choose. No secret upcharge, just a straight recommendation.
Common Chimney Liner & Rebuild Problems We See in Greenpoint Homes
- Oversized flues eating clay tile from the inside. Coal-sized flues venting gas appliances sweat acidic condensation. The tile spalls and collapses before you ever see exterior damage. In Greenpoint, this is the single most common reason a liner replacement gets scheduled.
- Abandoned flues turned into water channels. Gut renovations sealed the old parlor and kitchen flues, but many are still open at the top and clogged with pigeon nests and old liner debris. Rain soaks through and migrates into the shared party wall, damaging your building and your neighbor’s.
- Freeze-thaw mortar erosion near Newtown Creek. The elevated humidity off the East River and Newtown Creek speeds up mortar joint breakdown on exposed chimney stacks. Greenpoint chimneys need repointing and partial rebuilds at shorter intervals than inland Brooklyn.
- Cross-unit draft reversal in multi-family flues. When several gas appliances share one chimney across different floors, one weak draft can pull exhaust from another unit’s boiler back into a living space. We see it most often on tenements near the waterfront, where wind pressure off the river adds another variable.

FAQs - Chimney Liner & Rebuild in Greenpoint
Greenpoint gas appliances backdraft because the original chimney flues were sized for coal furnaces, not for today’s gas boilers and water heaters. A coal flue is too wide and too cold, so the exhaust never gets enough lift to clear the top. The cooler gas lingers, condenses, and loses its draw, especially when wind off the East River pushes against the stack. A correctly sized stainless liner fixes the draft by matching the flue to the appliance. Call (929) 822-6306 and we’ll camera the flue to confirm before any work is recommended.
Abandoned flues cause neighbor damage when they’re left open at the top and fill with pigeon nests, collapsed clay tile, and standing rainwater. That water soaks through the masonry and migrates into the shared party wall, staining and weakening the structure on both sides. We’ve pulled entire sections of dead flue out of Greenpoint tenements where the partner wall was wet from a cracked liner nobody knew was there. Capping a dead flue and rebuilding the crown stops the water at the source.
Yes, a partial rebuild is common on shared Greenpoint chimney stacks. The top five to ten courses above the roofline take the worst of the freeze-thaw cycle, and a partial rebuild replaces those courses, repoints the joints, and pours a new crown without touching the lower flues. It’s cheaper, faster, and often the only work the chimney actually needs. We’ll show you photos of the failed masonry before anything comes apart.
The smoke chamber is the transition between the firebox and the flue, and if it’s rough, corbeled, or full of loose mortar, the smoke stalls there and backs up into the room. That’s why a liner alone isn’t always enough. In Greenpoint parlor fireplaces that were sealed and later reopened, we commonly find the smoke chamber in poor shape. Parging it smooth with a ceramic product like HeatShield makes the fireplace draw cleanly through the new liner. Otherwise you’re lining a flue that still can’t breathe.
A multi-family Greenpoint chimney serving several gas appliances should be inspected once a year, burn or no burn. Chimneys break in the off-season too, and in a building where one flue serves three units, a small liner crack in one unit becomes a carbon monoxide risk in another. An annual camera inspection catches the spalling tile and hidden moisture before it becomes a rebuild. The sweep who shows up will show you the footage, plain and simple.
