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 Williamsburg
A chimney liner replacement or rebuild in Williamsburg typically runs $1,800-$4,200 for a standard rowhouse flue and $2,800-$6,500 when we’re dealing with the oversized industrial flues common in converted loft buildings. Most liner work in Williamsburg takes one day once we’re on the roof; a full rebuild usually runs two to three days depending on access and how much masonry has let go. If you’re staring at a crumbling crown or a liner that’s burned through, call (516) 289-9316 and Wendell will talk you through what you’re actually dealing with before anyone climbs a ladder.
The honest truth is, Williamsburg chimneys are different from the rest of Brooklyn. The converted factory and warehouse buildings that line Kent Avenue, Wythe Avenue, and the waterfront blocks were never designed for residential fireplaces. Their flues were built for industrial boilers, and thirty years of condo conversions haven’t changed that fact underneath the brickwork. We know what we’re looking at when we open one up, because Wendell has been working these chimneys since 1999, and he’s seen every retrofit mistake the 1990s loft boom could produce.
Before quoting anything, we inspect. Camera down the flue, eyes on the crown, and a plain-English explanation of what we found. You see the same footage we see. No pressure, no mystery recommendations. If the liner can wait a season, we’ll tell you that. If it can’t, you’ll see exactly why on the screen.
Why Top Hat Chimney Is Williamsburg’s Preferred Chimney Liner & Rebuild Company
Walk down Berry Street or Bedford Avenue and ask anyone who’s had chimney work done in the last decade. The name that comes up is Top Hat, because Wendell Pike has been climbing Williamsburg roofs since before the waterfront towers went up. The local reputation matters more here than in most neighborhoods. These rowhouses share party-wall chimney stacks, which means one owner’s liner failure can leak into a neighbor’s unit two floors up. That’s not the kind of job you hand to a national outfit that rotates a stranger through every Tuesday.
Every Williamsburg customer we work with gets the same deal, and it’s in writing. The 90-Day Done Right Promise means that if the liner or rebuild isn’t right after we’ve finished, one call brings Wendell back to make it right. No re-invoicing, no argument. We also answer our own phones, around the clock. Not a call center. If you call at midnight worrying about a chimney fire you smelled from the top floor, you’ll get a live person, and there’s a good chance it’s Wendell himself.
We give you a real arrival window and we call if it slips. Our crew arrives in uniform, background-checked, and they know Williamsburg’s building stock because they’ve been inside it for years, not because they read a training manual. The number you hear on the phone is the number on the invoice. That’s not a marketing line; it’s how we’ve kept working in this neighborhood for over two decades while other outfits come and go.
Williamsburg homeowners have specific concerns: shared stacks, DOB compliance on converted lofts, and water intrusion off the East River. We’ve handled hundreds of these cases, which means we walk in understanding the building before we even look at the flue. That local knowledge saves you time and keeps you from paying for work that the structure doesn’t actually need.
Our Chimney Liner & Rebuild Services in Williamsburg
Our Chimney Liner & Rebuild team handles the full scope of liner and masonry work, but here are the services Williamsburg calls us about most often.
Stainless Steel Liner
For Williamsburg rowhouses built between 1880 and 1930, the original clay tile liners are well past their intended service life. A stainless steel liner sized correctly to your appliance stops flue gases from leaking into wall cavities and neighboring units. In loft buildings, this is even more critical: the original industrial flue is almost always too large, and a properly sized stainless liner is what restores the draft. We install durable stainless systems, including the flexible liners we’ve relied on for years.
Flexible Liner
When the chimney has offsets or runs through multiple floors of a converted Williamsburg factory building, a rigid liner often won’t navigate the path. A flexible liner handles the turns without opening up walls or tearing out brick. We use it when the geometry demands it and we tell you plainly when a rigid liner would do the job better. For most Williamsburg loft retrofits, this is the conversation we end up having.
Liner Replacement
If your liner is cracked, perforated, or simply missing because a 1990s conversion crew skipped it, replacement is not a cosmetic upgrade. It’s the difference between a working chimney and a carbon monoxide path into your apartment. In Williamsburg’s attached rowhouses, a failed liner in one unit can send flue gas into the adjoining unit. We camera-inspect every liner before we recommend anything, and we show you the footage. You’ll know why the replacement is necessary because you’ll have seen the gap with your own eyes.
Partial Rebuild
In Williamsburg, the most common partial rebuild we do is from the roofline up: crown, top courses of brick, and the flue tile reset. The East River moisture accelerates spalling at these exposed sections, and once water gets behind the crown, the damage spreads down the stack. A partial rebuild stops that progression and typically runs a day to a day and a half. We match the brick and mortar to your building’s era so the repair doesn’t scream at you from street level.

Trusted Brands We Service in Williamsburg
We stock and install liners and components from manufacturers we’ve worked with since the late 1990s: Gelco, Olympia Chimney, and Famco. These are the brands that hold up to Williamsburg conditions, the wet winters off the river and the temperature swings that crack lesser materials. Because we keep the common sizes and fittings on our trucks for Williamsburg work, we’re not chasing parts across the city when your flue is open and your building is waiting. Faster turnaround, same-day liner installation on most jobs, and the manufacturer’s warranty is registered in your name before we leave.
Common Chimney Liner & Rebuild Problems We See in Williamsburg Homes
- Oversized loft flues from industrial-era buildings. A flue built for a factory boiler is sometimes three or four times the diameter a residential fireplace needs. That means weak draft, smoke blowback, and creosote building up fast because the gases stall and cool inside the oversized space. The fix is a correctly sized liner; the crew that doesn’t recognize the problem will keep cleaning it and wondering why you’re unhappy.
- Shared party-wall stacks in attached rowhouses. One stack serves multiple units across several floors. When a liner fails in one unit, the flue gases don’t necessarily go up and out, they can migrate laterally into the adjacent liner. That’s a carbon monoxide risk for a neighbor who doesn’t even have a fire lit. We isolate and line the compromised flue rather than assuming the whole stack needs demolition.
- Crumbling crowns from East River moisture. The persistent damp air off the waterfront works into the mortar at the crown, freezes, and pops it apart year after year. By the time you see brick chunks on the roof, water has usually been getting behind the liner and flashing for months. Annual inspection near the waterfront isn’t a suggestion; it’s a prevention strategy.
- Loft fireplaces with no liner at all. A surprising number of the late-1990s conversion jobs connected residential fireplace inserts directly to the old industrial stack with no liner whatsoever. That’s not just inefficient; it’s moving combustion byproducts through brick that should be carrying them at all. We find this often enough that it’s one of the first things we check on Williamsburg loft work.
Pricing for Chimney Liner & Rebuild in Williamsburg, NY
Here’s the straight answer on Williamsburg pricing. A stainless steel liner installation in a standard rowhouse flue runs $1,800-$3,200 depending on height and access. A flexible liner in a converted loft with multiple offsets typically runs $2,400-$3,900. A partial rebuild from the roofline up is generally $2,500-$4,800. Full chimney rebuilds in Williamsburg, where we’re dealing with industrial-era stacks or heavily damaged party-wall chimneys, range from $6,000-$14,000 depending on access, permits, and how much masonry has to come down before it goes back up.
What changes the number: roof access (many Williamsburg roofs are tight, with decks and mechanical equipment), the total flue height, whether scaffolding or a lift is required, and whether we’re working around shared stacks with live neighbors. We provide a fixed quote before work begins, and that number is the number. We offer free estimates throughout Williamsburg, we’ll give you a free second opinion on any written estimate you’ve received, and there’s no trip charge for calls in our service county. Seniors and veterans always get 10% off with Top Hat.
Full Chimney Rebuild
A full rebuild in Williamsburg means taking the stack down below the roofline, sometimes down to the attic floor or further, and reconstructing it with proper flue lining, new crown, new flashing, and correct smoke chamber dimensions. For loft buildings with architectural chimneys, this can mean reclaiming a chimney that was never right in the first place. We handle the permits, we work with your building’s schedule, and we keep the neighboring property clean while we’re at it. This is not a patch job; this is a structural repair that adds decades to the building.
On a converted warehouse loft along Kent Avenue, our crew found a 12-inch industrial flue serving a late-1990s fireplace insert. The oversized liner caused poor draft and third-degree creosote glaze we removed only after installing a DuraFlex stainless steel liner sized to the appliance, then rebuilt the smoke chamber and reset the firebox to correct the airflow. That’s the difference between a chimney cleaning and a chimney correction, and it’s the kind of thing you only find when the sweep actually knows what loft conversions did wrong.

FAQs - Chimney Liner & Rebuild in Williamsburg
The short answer is that the flues in Williamsburg’s converted factory buildings were built for industrial boilers, not residential fireplaces, which means they’re dramatically oversized for the job. When a fireplace insert fires into a flue that’s three or four times too large, the gases cool too fast, stall, and leave creosote behind at a much faster rate. That creosote becomes an ignition risk, and the acidic condensate attacks the flue walls. A properly sized stainless steel liner fixes the draft and gives the system the start it never had. Brownstone flues have their own issues, but they were at least sized for residential use, which is why loft liners tend to fail sooner. Call (516) 289-9316 and we’ll camera the flue and show you what’s happening in your specific building.
We inspect the entire stack first, and then we isolate the specific flue that’s failed. In a shared party-wall chimney, you’re often dealing with two to four separate flues running side by side inside one masonry stack, and you can’t always access one without going through common roof space. We coordinate with the building owner and adjacent unit owners when needed, and we line the compromised flue individually rather than treating the whole stack as one problem. The goal is to make your unit safe and functional without disrupting neighbors or doing demolition that isn’t warranted. Wendell has handled enough of these shared-stack jobs that he can tell you in the first conversation what’s going to be straightforward and what’s going to need building cooperation.
Yes, and it’s one of the most consistent calls we get from Williamsburg waterfront buildings. The moisture off the East River soaks into the mortar at the crown, and when it freezes, it expands and pops the joints apart. That cycle repeats every winter, and it works much faster in the river-adjacent blocks of Williamsburg than it does further inland in Brooklyn. If you’re seeing brick fragments on the roof or the crown looks like it’s shedding, get it inspected before the water works down the stack and behind the liner. A partial rebuild of the crown and top courses stops the progression, and it’s a fraction of the cost of a full stack rebuild later. Call for a camera inspection and we’ll tell you whether you need to act now or can schedule it for the spring.
A partial rebuild means we’re rebuilding from the roofline up: crown, top brick courses, flue tile reset, and new flashing. It’s typically a one to two day job and it solves the most common Williamsburg failure, which is water intrusion at the top of the stack. A full chimney rebuild means the entire structure above the roofline or down to the attic floor is coming down and going back up, with new brick, new liner, new smoke chamber, and new crown. For loft buildings with industrial-era chimneys, a full rebuild is the only option when the masonry has lost structural integrity or when the original flue dimensions make any liner installation impossible without reconstruction. We’ll tell you which one you need based on the camera footage, not based on which job is bigger. The estimate is free, and so is the honesty.
In most Williamsburg loft buildings, yes. The original industrial flue is usually large enough to accommodate a new stainless steel liner without any demolition at all. We measure the existing flue, size the liner to your fireplace or heating appliance, and pull it through the stack from the roof down. Where offsets or old mortar protrusions make that impossible, we may need to open a small access point at a bend, but we do not tear down the stack for a liner installation. The only time we’d recommend a full rebuild instead of a reline is when the masonry itself has failed or the flue is so compromised that a liner wouldn’t be safe to install. Call (516) 289-9316 for a camera inspection and we’ll show you the condition of the flue before we recommend anything.
For most Williamsburg jobs, we can schedule the inspection within a few days and complete the repair or rebuild the same week. We keep our Williamsburg call volume realistic instead of booking jobs back to back, which means Wendell is not rushing your inspection so he can make it to the next appointment. For emergencies like a chimney fire or a sudden flue failure during heating season, call and talk to a live person; Wendell will tell you honestly whether we can get there today or whether you need to contain the situation until morning. We do not promise same-day service as a matter of policy, because promising it and not delivering is worse than telling you the truth up front. What we do promise is that someone answers the phone.
Generally, yes, by about 10-20% compared to brownstone-heavy neighborhoods like Park Slope or Bed-Stuy, for two reasons. The flues are often taller and more difficult to access, and the work frequently involves correcting problems that date back to an improper 1990s conversion. That correction work adds time and material. But the cost per year of safe operation is actually lower, because a properly sized liner means fewer cleanings, fewer draft complaints, and no expensive emergency repairs from a chimney fire you could have prevented. We quote a fixed price before we start, so you’ll know the full Williamsburg-specific number before anything comes off the truck.
Every liner and rebuild job in Williamsburg carries our 90-Day Done Right Promise in writing. If the work isn’t right, one call brings Wendell back to make it right at no additional cost. The manufacturer’s warranty on the liner components runs longer and is registered in your name. We’ve been honoring our word in Williamsburg since 1999, and that’s exactly why so much of our work here comes from referrals on Bedford, Berry, and Wythe.
