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.
Fast, Reliable Chimney Cleaning & Sweep Across Brentwood
A chimney sweep in Brentwood typically runs $189-$329 for a standard cleaning with a Level 1 inspection, and most jobs are done in under two hours. If your flue hasn’t been looked at in a few years, the longer answer is that the price depends on creosote buildup, liner condition, and whether you have a fireplace or a boiler venting through the same flue, which is extremely common in this part of Long Island. We know these houses. We’ve been inside hundreds of Brentwood chimneys since Wendell Pike started Top Hat Chimney in 1999, and we can tell you straight whether you need a simple sweep or something more. Call (516) 968-5380 and you’ll get a live person, not a call center, and an honest number before any tool comes off the truck.
Why Top Hat Chimney Is Brentwood’s Preferred Chimney Cleaning & Sweep Company
Ask anyone on your street. Brentwood is a tight-knit hamlet, and after 29 years of working these neighborhoods, Wendell and his crew run into customers at the grocery store, not just at the front door. That’s the difference between us and the national outfits that send a different stranger every season. The sweep who shows up at your door in Brentwood is background-checked, uniformed, and works for a company whose owner puts his own name and license number on every job in writing.
Brentwood customers call us because we give them a real arrival window and actually call if it slips. We understand the homes here: the split-levels off Washington Avenue, the ranches along Suffolk Avenue, the Capes near the Pilgrim State site. And every completed job carries our 90-Day Done Right Promise. If it’s not done right, one call brings us back. No arguing, no re-quote. That’s the promise in writing, stamped on your invoice.
We also answer the phone 24/7. Not a voicemail box. A live person. It may well be Wendell himself picking up at midnight because a nor’easter just ripped a cap off your chimney and you’re watching water drip into the firebox.
Our Chimney Cleaning & Sweep Services in Brentwood
Our Chimney Cleaning & Sweep team covers the full range, from a quick annual sweep to a full Level 2 camera inspection after a storm. Here’s what most Brentwood homeowners call us for.
Annual Sweep
The baseline service every wood-burning fireplace in Brentwood needs once a year, burn or no burn. We remove creosote and soot from the flue, smoke chamber, and firebox, then run a Level 1 inspection while we’re in there. In Brentwood’s 1950s and 60s homes, an annual sweep is also the cheapest way to catch clay tile cracks before they become a $4,000 reline.

Level 1 Inspection
A visual check of the accessible parts of the chimney, included with every sweep. Good for confirming your flue is clear and your damper works. But on a Brentwood ranch with an original clay tile liner, a Level 1 only tells you the flue looks okay from the top and bottom. It cannot see what’s happening mid-flue.

Level 2 Inspection
This is the camera inspection. We run a scope down the full length of the flue and record footage you can watch with us. If your Brentwood home was converted from oil to gas in the 1980s or 90s, this inspection is the only way to see whether the old 8-inch clay tile liner is spalling behind the walls. We recommend a Level 2 after any chimney fire, before buying a home, and after any major storm that knocked your cap loose.

Creosote Removal
First-degree creosote is a brush job. Third-degree is a glaze that can fuel a chimney fire. Brentwood’s freeze-thaw cycles and nor’easter moisture don’t create creosote, but they accelerate the conditions that do. Cracked crowns let water into the flue, and wet creosote hardens into that sticky, tar-like second-degree stage faster than in drier houses. We remove all three stages, and if we find glaze we’ll tell you plainly and show you the footage.

Soot Removal
Every gas appliance produces some soot, but when a Brentwood home vents a 90,000-BTU gas boiler into a flue built for a 200,000-BTU oil burner, soot and condensation build up faster than they should. We clean it out and check for the white efflorescence that tells us the flue is venting too cool.

Trusted Brands We Service in Brentwood
When a Brentwood home needs more than a sweep, we install and service liners and components from DuraFlex, HeatShield, Gelco, and Copperfield. We stock common replacement parts locally so you’re not waiting on a backordered cap while a nor’easter is in the forecast. Wendell chose these brands because they hold up to Long Island conditions, and because he’s been installing them long enough to know their failure points. A DuraFlex stainless liner sized correctly for a gas conversion will outlast the original clay tiles by decades.
Common Chimney Cleaning & Sweep Problems We See in Brentwood Homes
- Cracked chimney crowns from freeze-thaw cycling. Brentwood sits well inland, losing the thermal buffering of Great South Bay that keeps coastal hamlets like Bay Shore a few degrees warmer in winter. More freeze-thaw cycles per season means more spalling and open mortar joints on these 50-to-70-year-old single-wythe brick chimneys.
- Oversized clay tile flues from oil-to-gas conversions. A large share of Brentwood homes converted from oil to gas in the 1980s through 2000s without installing a properly sized stainless liner. The result is a 90k-BTU appliance venting into a flue built for a 200k-BTU oil burner. That flue vents too cool, condensation forms, and white efflorescence streaks down the exterior brick. We see it from the curb on calls all over the hamlet.
- Rusted galvanized caps and flashing from nor’easter salt air. Galvanized components corrode within 5 to 10 years in Brentwood’s wind-driven, salt-laden storms. But many homeowners replace only the cap and leave the flashing leaking, then call us back for water stains around the chimney chase.
- Creosote in the smoke chamber of split-levels and Capes. The tight bends and shallow smoke shelves in 1950s-era fireplaces collect creosote faster than modern units. If you smell your last fire a month after burning, that’s creosote sitting in the chamber.

FAQs - Chimney Cleaning & Sweep in Brentwood
Yes, if the original clay tile liner is cracked or if the chimney was converted from oil to gas. A 1950s flue built for an oil burner is oversized for a modern gas appliance, and it vents too cool whether you burn wood or not. That cool exhaust condenses inside the flue, and the acidic condensate eats the mortar joints. A stainless liner sized to the current appliance fixes the draft and stops the deterioration. Call (516) 968-5380 and we’ll camera-scope the flue so you can see for yourself.
That white streaking is efflorescence, and it’s a telltale sign of condensation inside an oversized flue. When a Brentwood home converted from oil to gas without a properly sized stainless liner, the flue vents too cool, moisture condenses on the clay tile, and the dissolved salts migrate through the brick. It’s not just cosmetic. It means your flue is deteriorating from the inside and may be backdrafting carbon monoxide into the house. Call us for a Level 2 inspection and we’ll show you the camera footage.
Brentwood homes should be inspected every year, same as Bay Shore, but for different reasons. Bay Shore chimneys fight salt corrosion on caps and flashing. Brentwood’s inland location means more freeze-thaw cycles, so crowns and mortar joints crack faster here. We recommend an annual sweep with Level 1 inspection, and a Level 2 camera inspection every 2 to 3 years if your chimney is original to a 1950s or 60s home. Call (516) 968-5380 for an exact quote; estimates are free.
No. Third-degree creosote is a hardened glaze that no brush removes. It requires chemical treatment and specialized rotary tools, and it’s the form of creosote most likely to fuel a chimney fire. We carry the chemicals and the equipment to break it down, but you should expect an additional $150-$300 on top of the standard sweep price. If you haven’t had your flue cleaned in years, call (516) 968-5380 and we’ll inspect for free before quoting.
Yes. Galvanized caps and flashing in Brentwood corrode within 5 to 10 years from nor’easter-driven salt air. Stainless costs more upfront but lasts decades and won’t leave rust streaks down your chimney. And while we’re replacing the cap, we’ll check the flashing too. Replacing only the cap leaves the flashing leaking, which is the most common reason homeowners call us back for water stains. We stock Copperfield stainless caps locally.
