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 Cleaning & Sweep Company
We’re not a franchise that rotated in last spring. Wendell Pike founded Top Hat Chimney in 1999, and he still answers the phone plenty of nights. Our crew knows Williamsburg the way you only can after a couple decades of climbing its roofs, from the Greek Revival rowhouses on South 2nd Street to the brick walk-ups off Graham Avenue and the converted warehouses along Wythe and Kent. That matters because Williamsburg chimneys are not like chimneys anywhere else in Brooklyn, and the sweep who shows up at your door needs to know the difference before the ladder comes off the truck.
Ask anyone on your street. Our Chimney Cleaning & Sweep crew has built its reputation in this neighborhood one flue at a time. We give you a real arrival window, not a four-hour guess, and we call if it slips. You see the camera footage before we recommend anything. No mystery work, no price that changes at the door. The number you hear on the phone is the number on the invoice.
Our Chimney Cleaning & Sweep Services in Williamsburg
We offer a full range of chimney cleaning and inspection work across Williamsburg, and we tailor every visit to the building. A rowhouse flue off Bedford Avenue gets a different inspection than a loft conversion off Berry Street, because the problems are different. Call (516) 289-9316 for a free estimate and we’ll tell you what your setup actually needs.
Level 1 Inspection
A Level 1 inspection is what most Williamsburg homeowners need at their annual cleaning. We check the accessible portions of the flue, the damper, the firebox, and the Williamsburg Chimney Cap & Crown. In attached rowhouses, we also confirm the flue is isolated from the units on either side, because a shared stack with a cracked mortar joint can send debris into a neighbor’s flue without anyone noticing until there’s a problem.
Level 2 Inspection
If you’ve just bought a Williamsburg property, converted a fireplace, or had a chimney fire, a Level 2 inspection is what the situation calls for. We run a camera through the full flue and check what is behind walls and in the smoke chamber. This is the inspection we recommend for any loft buyer in Williamsburg, because too many converted fireplaces were connected to flues never sized for residential use. You need to know what’s actually in there, and the camera footage plus a plain-English verdict is what we give you, every time.
Creosote Removal
Creosote is what makes a dirty chimney dangerous. First-degree is a brush job. Third-degree is a glaze, and it does not brush out. In Williamsburg loft conversions especially, we see third-degree creosote form within two heating seasons because the flue diameter is oversized and the draft is weak. We have the rotary tools and the patience to remove built-up creosote properly, and we’ll tell you plainly if a liner resizing is the real fix instead of just another cleaning.
Soot Removal
Soot is lighter than creosote but it still cuts draft and builds up inside fireplaces, smoke chambers, and dampers. We remove soot from fireplaces, wood stoves, and gas appliance flues across Williamsburg, from single-flue brownstones to larger properties on the Northside with multiple fireplaces. If your fireplace leaves a film on the mantel or the room smells like smoke days after a fire, soot has usually gotten where it shouldn’t be.

Trusted Brands We Service in Williamsburg
We work with the brands that hold up, and we stock parts locally so a Williamsburg repair doesn’t wait on a national parts depot. We install and service liners and components from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. If you have an older Copperfield damper or a Gelco cap that is seen better days, we can usually match it or source the right replacement quickly. We’d rather tell you a part needs to be upgraded than send you home with a patch, and we show you why on camera before you spend a dollar.
Common Chimney Cleaning & Sweep Problems We See in Williamsburg Homes
- Oversized loft-conversion flues. Fireplaces added to Williamsburg warehouse conversions in the 1990s and 2000s were often vented into flues originally sized for industrial boilers, two to three times wider than a residential liner. That kills draft and leaves creosote behind even after a standard cleaning.
- Party-wall stack contamination. Most Williamsburg rowhouses share chimney stacks with the buildings on either side. A cleaning that doesn’t verify flue isolation can push debris into a neighbor’s flue, and that’s a liability concern every company working here should be thinking about.
- East River moisture at the crown. Water off the East River eats at mortar and brick. Crowns on Williamsburg rooftops spall faster than chimneys further inland in Brooklyn, and water that gets into the smoke chamber corrodes dampers and liner sections before you see any sign from inside.
- Multiple flues, multiple appliances, one inspection schedule. Larger Williamsburg properties often run a wood-burning fireplace, a gas insert, and a water heater through separate flues. They all need annual attention, but they rarely need it at the same intensity.
Pricing for Chimney Cleaning & Sweep in Williamsburg, NY
Here’s the honest picture of what chimney work costs in Williamsburg. A standard single-flue sweep runs $189-$289, including a Level 1 inspection. A Level 2 inspection with a full camera run is $325-$500, depending on the building. Creosote removal beyond a basic brushing starts at $150 and goes to $450 or more for heavy third-degree glaze, which usually means a rotary tool and significantly more time. Soot removal for a fireplace or insert runs $120-$250. Loft conversions and party-wall stacks trend toward the upper end of every range because the flue geometry is harder to clean properly. You get a firm quote before we start, and the estimate is free. Call (516) 289-9316 and Wendell will talk you through what applies to your building.

FAQs - Chimney Cleaning & Sweep in Williamsburg
Your loft fireplace is probably venting into a flue built for an industrial boiler, far larger in diameter than a residential appliance needs. That oversized flue cools the smoke too quickly, so creosote condenses and glazes faster. The fix is resizing the liner or insulating it, not just more frequent cleanings. Call (516) 289-9316 and we’ll camera the flue and show you exactly what’s happening.
Yes, we clean individual flues, and we verify isolation from the adjacent units before we start. Party-wall stacks in Williamsburg need a sweep who checks for mortar joint gaps and shared smoke chambers, because debris that drops into a neighbor’s flue becomes your problem. We do it carefully, and we’ll tell you if we find a crack that needs attention before it turns into a dispute or a blockage.
They usually require a Level 2 inspection with a full camera run, because the flue interiors are non-standard and often undocumented. We check for oversized diameter, improper offsets, and compliance with current NYC DOB requirements. A standard visual check on a converted loft misses the things that actually go wrong, and a real inspection is the only way to know if your fireplace is safe to burn. Call (516) 289-9316 to schedule one.
Once a year, burn or no burn. Chimneys break in the off-season too, and in Williamsburg the East River moisture keeps working on your crown and mortar even when the fireplace sits cold. Annual cleaning catches early problems before they become rebuilds. Ten minutes of burning still deposits creosote, and the off-season moisture makes it acidic. Call (516) 289-9316 to book your annual sweep.
Sometimes yes, if the liner is intact and the glaze is accessible. Third-degree creosote is hard and glossy, and it usually requires rotary tools and real time. But if the liner underneath is cracked or deteriorated, cleaning it is a stopgap, and we’ll tell you that plainly with the camera footage to prove it. Call (516) 289-9316 for an honest assessment, not a sales pitch.
In a converted warehouse on Wythe Avenue, our tech found a 1990s fireplace venting into a 12-inch brick flue originally sized for a boiler. The oversized diameter caused sluggish draft and third-degree creosote glaze within two heating seasons. We performed a Williamsburg Chimney Liner & Rebuild with an insulated DuraFlex stainless liner sized to the appliance, restored proper draft, and brought the setup into NYC DOB compliance. That’s the kind of finding a standard brownstone sweep would have missed, and it’s the reason Williamsburg homeowners call us instead.
If your chimney has not been cleaned this year, or you just bought a place and you’re not sure what’s behind the drywall, call (516) 289-9316. We’ll schedule a time that works, show up when we say we will, and give you a straight answer with the camera footage to back it up. Free estimates, free second opinions on written competitor bids, and a 90-Day Done Right Promise on every job. Top Hat Chimney has been the Williamsburg sweep homeowners talk about since 1999.
