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.

Why Top Hat Chimney Is Williamsburg’s Preferred Chimney Repair Company
Top Hat Chimney has been owned and operated by Wendell Pike since 1999. We publish our address and license number, and we back every single job with our 90-Day Done Right Promise in writing. That matters in Williamsburg, where so many property owners have already been through the wringer with a national chain that quoted $149 on the phone and handed them a $2,400 invoice at the door. We don’t play that game. Our phones are answered by a live person around the clock, and it may well be Wendell himself who picks up when you call.
Williamsburg’s building stock is not like the rest of Brooklyn. You’re in attached brick rowhouses from the 1880s and converted factory lofts along the East River, and those buildings have chimney systems that behave differently from the brownstones a few stops south. We’ve run chimneys in Williamsburg long enough to know the difference between a routine repointing job on a Southside rowhouse and a linered loft flue that was never sized right to begin with. That’s why homeowners on the Northside and around McCarren Park keep our number on their fridge.
When you call, we give you a real arrival window and call if it slips. Our sweeps are background-checked, uniformed, and trained to look at your chimney the way you’d look at the house next door. No pressure, no upsell pitch. Camera footage and a plain-English verdict. Every time, no exceptions.
Our Chimney Repair Services in Williamsburg
Mortar Repointing
Mortar repointing in Williamsburg typically costs $18-$35 per square foot of brick face, and it’s the single most common repair we do on the row of attached brick homes between Grand Street and the BQE. The East River moisture works into the joints every winter, softening the old lime mortar and leaving gaps that let water behind the brick. We cut out the failed mortar, pack in a compatible mix, and match the color so the patch doesn’t shout at you. In a city where your chimney stack is shared with the neighbor on both sides, clean mortar joints are the first line of defense against slow water damage.
Spalling Brick Repair
Spalling brick repair in Williamsburg usually runs $600-$1,500 for a standard chimney crown or stack face, depending on how many bricks have flaked. Spalling is what happens when moisture gets into the brick, freezes, and pops the face off the masonry. We see it constantly up on rooftops near the Williamsburg waterfront, where the marine air sits on the brick all winter. We’ll match the brick, replace the failed units, and tell you plainly whether the rest of the stack is sound or whether you should budget for more extensive work next year.
Chimney Waterproofing
A chimney waterproofing job in Williamsburg generally costs $450-$900 for a standard residential stack. We use breathable waterproofing products from Gelco and Olympia Chimney, which soak into the masonry and block liquid water without trapping vapor inside the brick. That matters here, because a chimney on a Williamsburg roof is exposed to East River air on three sides. A lot of people think waterproofing is optional. It isn’t. One good application every five to seven years saves you a much larger masonry repair bill later.
Flashing Repair
Flashing repair in Williamsburg falls in the $350-$1,200 range for most jobs. Flashing is the metal that seals the gap where the chimney passes through the roofline, and on Williamsburg rooftops it gets worked hard by wind and driven rain off the East River. When the flashing fails, water runs down the chimney chase and into the ceiling below. We replace it with proper counterflashing, seal the seams, and test the repair before we leave the roof. No putting a bead of caulk over a rusted pan and calling it done.

Common Chimney Repair Problems We See in Williamsburg Homes
- Oversized loft flues that kill draft. Converted factory and warehouse buildings along the Williamsburg waterfront often have flues originally sized for industrial boilers. A residential fireplace hooked to a 14-inch commercial flue won’t draft properly, smoke rolls back into the room, and creosote builds up fast. Standard brownstone flue work never accounts for this.
- Party-wall chimney stacks with shared flues. In attached rowhouses across Williamsburg, your chimney shares a wall with the unit next door. If one unit’s spalling brick is repaired without verifying flue isolation, you can open a pathway for flue gas to move between tenants. That’s a liability, and we check for it every time.
- East River moisture eating crown joints. The persistent damp air off the water accelerates mortar erosion at chimney crowns faster than in inland Brooklyn neighborhoods. Most Williamsburg property owners only notice it once staining appears on the ceiling or water runs down the brick after a hard storm.
- Third-degree creosote in gas-converted fireplaces. Loft conversions from the 1990s and 2000s often installed gas fireplaces as amenities, but the flues were never downsized to match. The result is a hard, glossy creosote glaze that can’t be brushed out and requires chemical treatment or a liner replacement.

FAQs - Chimney Repair in Williamsburg
Your flue is almost certainly oversized for the firebox, a problem we see constantly in Williamsburg loft conversions where the fireplace was connected to a flue originally built for an industrial boiler. The oversized diameter kills draft, and smoke rolls back into the living space no matter how clean the flue is. The fix is a properly sized insulated liner, usually a DuraFlex system, which reduces the cross-section and restores proper airflow. Call (516) 289-9316 and we’ll camera the flue and show you exactly what’s happening on the screen.
Once a year, burn or no burn. The moisture off the East River accelerates mortar joint erosion and spalling brick at chimney crowns faster than in inland parts of Brooklyn. If you skip the inspection, water intrusion can go unnoticed behind the masonry for a full season, and by the time you see the staining it’s a repair job instead of a maintenance call. Annual camera inspection costs a lot less than a crown rebuild. We’ll book you for the same month every year so you don’t have to remember.
Yes, and this is one of the biggest liability concerns in attached Williamsburg rowhouses with shared party-wall chimney stacks. When we repair spalling brick on one unit’s side of the stack without verifying flue isolation, it can open pathways for flue gas to cross between tenants. We check flue isolation on every shared-wall job, document it with camera footage, and include it in our written report. You’ll know exactly what we found, and your neighbor won’t be breathing your smoke.
Third-degree creosote is a hard, glossy glaze that forms when a flue is burning too cool for the size of the firebox. In Williamsburg loft conversions, the flues were often sized for commercial boilers, so a residential fireplace doesn’t generate enough heat to keep the creosote from condensing on the flue wall. Once it glazes, you can’t brush it out. It requires chemical treatment or a liner replacement. This is why so many Williamsburg loft owners are surprised at their first cleaning. We see it more here than almost anywhere else we work.
Yes. Even a gas fireplace needs a watertight chimney. The flue carries combustion gases and moisture is still the enemy of the masonry that surrounds it. East River air will work on your crown joints every winter whether you burn wood or not. A Gelco waterproofing application on the stack costs $450-$900 and keeps the brick from spalling for years. Cheap insurance. Call (516) 289-9316 and we’ll give you the exact price for your building’s height and condition.
