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 Park Slope
Chimney liner replacement in Park Slope typically runs $2,800-$6,500, and most jobs take one to three days once materials are on site. A full chimney rebuild above the roofline in this neighborhood usually lands between $6,000 and $14,000 depending on how much of the Victorian corbeled brickwork needs to come down. We work in Park Slope every week, and we know what these 140-year-old stacks look like from the inside. Call (516) 289-9316 for an exact quote, and Wendell will walk you through what your flue actually needs.
Your flue doesn’t care how the fire looks. It cares how it breathes. And in Park Slope, between the salt air rolling in from Upper New York Bay and the freeze-thaw cycles that punish century-old brick, a lot of flues have stopped breathing the way they should.
Why Top Hat Chimney Is Park Slope’s Preferred Chimney Liner & Rebuild Company
The brownstones here were built between the 1870s and 1910s, which means nearly every chimney stack in the neighborhood is older than the people living beneath it by a factor of three or four. Those stacks carry original clay tile liners that were designed for coal, converted for gas in the mid-century, and now sit behind fireplaces that owners want back in working order. We have pulled liners out of Park Slope flues that came out in pieces no bigger than a dinner plate. That is not a scare story. That is a Thursday.
What sets us apart is how we handle the job before we touch anything. The price Wendell quotes on the phone is the price on the invoice. Not a penny more. We show you the camera footage from inside your flue before we recommend anything, and you get a plain-English verdict, every time, no exceptions. Every job carries our 90-Day Done Right Promise in writing. If the work is not right, one call brings us back, and it costs you nothing.
Wendell founded this company in 1999, and he still puts his name and license number on every job. He has been inside more chimneys than he can count. The sweep who shows up at your door in Park Slope is background-checked, uniformed, and gives you a real arrival window. If that window slips, you get a call. And if you call us at 2 a.m. with a question, a live person picks up. It may well be Wendell himself.
Our Chimney Liner & Rebuild Services in Park Slope
Stainless Steel Liner
For Park Slope brownstones with wood-burning fireplaces being reopened after decades sealed, a stainless steel liner is usually the right answer. We install DuraFlex liners sized to your flue’s exact dimensions, including offset sections for the angled runs these old party-wall stacks always seem to have. A properly fitted stainless liner restores safe draft in a flue that may have been compromised since the Hoover administration. In this neighborhood, stainless holds up better than galvanized, and given the salt air off the harbor, that matters.
Flexible Liner
Some Park Slope flues have bends and offsets that make rigid sections impossible without opening the wall, which no brownstone owner wants. A flexible liner snakes through the existing passage and handles the kinks without disturbing the brick. It is a practical fix for older homes in the neighborhood where the original flue drifts off-plumb halfway up. We carry Copperfield flexible liner because we have seen how it performs in Brooklyn chimneys after ten and fifteen years of use.
Liner Replacement
When the original clay tile liner has cracked, offset, or collapsed entirely, patching is not an option. Liner replacement in Park Slope means pulling the old material and installing a new stainless system sized for the appliance venting through it. Given how many flues in this neighborhood were abandoned during the 1950s-70s gas conversions and then hastily brought back into service, Wendell sees collapsed liner sections more often here than in most Brooklyn neighborhoods. We run a camera first, show you the footage, and only then recommend the work.
Partial Rebuild
A partial rebuild addresses the portion of the chimney above the roofline: the corbeled brickwork, the crown, and the top few courses. In Park Slope, this is where the coastal freeze-thaw damage shows up first. Salt-laden air and winter moisture get into the mortar joints, the bricks spall and loosen, and eventually water migrates down into the flue and the wall cavities. A partial rebuild restores the structural top of the stack without touching what lives inside the house. We match brick and mortar color to the original as closely as the supply houses around Brooklyn will allow.

Trusted Brands We Service in Park Slope
We install and service products from DuraFlex, Copperfield, HeatShield, and Gelco. The reason we stick with those brands is simple: we have watched how they hold up in this specific climate. Park Slope sits close enough to Upper New York Bay that salt-laden air works on metal components year-round. Stainless steel flue caps, flashing, and liners last longer than their galvanized counterparts, and the brands we carry are built for that reality. If something fails under our 90-Day Done Right Promise, we make it right. Ask anyone on your street.
Common Chimney Liner & Rebuild Problems We See in Park Slope Homes
- Collapsed clay tile liners in reopened fireplaces. In row houses off Eighth Avenue and around Prospect Park, we routinely find flues that have fully collapsed because they were sealed during the gas-conversion era and never maintained. The camera sees it before we do. The fix is a stainless liner, not a sweep.
- Spalled and crumbling corbeled brick above the roofline. The decorative brick corbels on Victorian chimney tops are the first thing the salt air and freeze-thaw cycles attack. Loose brick and failing mortar joints let water into the stack, and if you wait, the rebuild gets bigger and more expensive.
- Third-degree creosote glaze beneath gas residue. Many Park Slope flues carry coal soot and creosote from before the mid-century conversions, with gas deposits layered on top. That combination hardens into a tar glaze that a brush cannot remove. It demands mechanical removal or liner replacement.
- Negative pressure from abandoned multi-flue stacks. Most brownstones here have one stack with three to five flues, and when some of those flues were bricked off decades ago, the remaining active flue can struggle to draw properly. A liner sized correctly for the current appliance fixes the draft.
Pricing for Chimney Liner & Rebuild in Park Slope, NY
Here is what you can expect to pay in this neighborhood. A stainless steel liner install in Park Slope runs $2,800 to $6,500 depending on flue length, offsets, and whether we are relining one flue or several in the same stack. Liner replacement lands in the same range, assuming the old liner comes out cleanly; if we have to break up collapsed clay sections first, add $400 to $900. A partial rebuild above the roofline starts around $3,500 for a modest crown and brick repair, and a full corbeled-top rebuild on a Victorian stack runs $6,000 to $14,000. Stainless steel costs more than galvanized up front, but with the salt air off the bay, it is the material we recommend. Every quote is free, and the number we give you over the phone is the number on the invoice. Call (516) 289-9316 and Wendell will give you an honest range before we even schedule the visit.

FAQs - Chimney Liner & Rebuild in Park Slope
Yes, it can. If your building sits within the designated NYC Landmarks Preservation Commission Historic District, which covers significant portions of Park Slope, any exterior chimney work visible from the street may need LPC approval before we touch the cap or anything above the roofline. This includes cap replacement and partial or full rebuilds above the roofline. Interior liner work does not trigger LPC review. We will tell you upfront whether your building qualifies and help you understand the process. Call (516) 289-9316 and we will walk you through it.
Expect a camera inspection, and do not be surprised if the footage shows a collapsed clay tile section, offset joints, or decades of hardened coal soot and creosote fused into the walls. Here in Park Slope, fireplaces sealed during that era sat untouched while the flue above them deteriorated. Before any cleaning can safely happen, we run a Level 2 camera scan. The liner often needs replacement, not a sweep. The good news is a stainless liner gets the firebox back to code, and we install them all the time off Fifth and Seventh Avenues.
Annually, and we mean it. The salt-laden air rolling off Upper New York Bay accelerates brick spalling and corrodes flashing faster than you will see in inland neighborhoods like Ridgewood or Glendale. Coastal freeze-thaw cycling widens hairline cracks in crowns until water gets down into the flue and the roof structure. Once a year, burn or no burn. Chimneys break in the off-season too. A quick inspection catches a $400 crown repair before it becomes a $9,000 rebuild.
Yes, in most Park Slope brownstones there is no need to open the neighbor’s side at all. The liner goes down through the flue opening from the roof access point or through the firebox, depending on the layout, and it snakes through the existing flue passage. The neighor’s side of the wall stays untouched. Party-wall stacks here are common, and we work carefully to keep the job on your side of the brick. We will confirm with a camera scan first and tell you exactly how the install will go before we start.
Repointing a crown means scraping out and replacing the mortar joints on the flat concrete surface at the top of the stack, a job that typically costs $400 to $900 in Park Slope. A partial rebuild means taking down and relaying the corbeled brick courses themselves, the decorative stepped brickwork you see from the street on so many brownstones between the park and the Gowanus. That runs $3,500 to $14,000 depending on how many courses are loose and how much matching brick we need to source. If the corbels are failing, repointing will not hold them. Call us at (516) 289-9316 and Wendell will tell you straight which one your stack actually needs.
