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.

AfterGelco Chimney Cleaning & Sweep in Brentwood: What to Know First
We clean and sweep Gelco chimney systems throughout Brentwood as an independent service provider, not a factory arm. Most Gelco sweeps run $189 to $289 for a standard open-faced fireplace with a masonry chimney, and we can usually get you on the schedule within a week. The number you hear when you call is the number you pay. No add-ons once we’re on the roof.
This page is for Brentwood homeowners who own a Gelco fireplace, stove insert, or chimney component and want someone who actually knows how these units behave after a few Long Island winters. If that’s you, call (934) 935-3847 and a live person answers. Could be Wendell himself.
How Gelco Products Fail - and How We Fix Them
Gelco makes solid products, but every brand has its patterns. Here’s what we actually see in Brentwood homes, not what a spec sheet says.
- Gelco Zero-Clearance Fireplace Units: These prefab boxes sit inside a framed chase, and the chase top flashing is often the first thing to go. Leaked water runs down into the firebox and mixes with soot, creating an acidic paste that eats at the refractory panels. When we sweep these, we check the chase top before we even touch the flue. A $40 flashing repair beats a $900 firebox rebuild every time.
- Gelco Air-Cooled Chimney Pipe: Air-cooled pipe uses airflow between the inner and outer walls to keep the outer pipe cool enough for wood framing. The problem? Brentwood’s humid summers and cold winters cause the outer wall to sweat, and that condensation traps creosote dust in the air gap. You can’t brush that out from below. We pull the cap, inspect the air channel, and clear it so the pipe actually cools the way it was designed to.
- Gelco Masonry Chimney Liners: Older Gelco fireplaces vented through clay tile get glazed creosote in the top third of the flue, right where the hot gases hit cold air. That’s the Brentwood pattern, especially in capes and colonials near Brentwood State Park where chimneys are exterior walls and never fully warm up. We remove the glaze with rotary chains when it’s caught early. Catch it late and you’re looking at a liner replacement instead of a sweep.
- Gelco Glass Door Assemblies: The tempered glass on Gelco doors seals against a rope gasket that stiffens after five or six seasons. Once it’s stiff, the seal leaks, the fire burns dirty, and you get soot on the glass that never quite wipes clean. During a sweep we check the gasket by feel. If it’s flat, we replace it with the right diameter rope. It’s a ten-minute fix most homeowners overlook for years.
- Gelco Blower Kits: The blower sits underneath the firebox and pulls in pet hair, dust, and ash fines from Brentwood’s older homes. A noisy blower on a Gelco unit is almost always a dirty squirrel cage, not a bad motor. We pull it, clean the fins, and it quiets right down. If the motor is actually shot, we tell you plainly and quote the replacement without markup games.
Our Gelco Chimney Cleaning & Sweep Process
Every job gets the same sequence, whether it’s a ranch in Brentwood with a Gelco insert or a two-story colonial with a full masonry system. Wendell Pike set this process years ago and it hasn’t needed changing.
- 1
You call, a person answers. We ask what unit you have, when it was last swept, and anything you’ve noticed: smell, smoke backing up, animals. We give you a flat price over the phone for the sweep and a free on-site quote for anything we find.
- 2
We show up on time, in uniform. Drop cloths go down before a tool comes off the truck. Your hearth and floors are protected from first step to last.
- 3
Visual and camera inspection of the Gelco unit and flue. We’re checking the firebox panels, damper, gasket seals, and the full flue run. You see the camera footage yourself, on the spot.
- 4
The sweep itself. Brush size matched to your flue diameter, HEPA vacuum running from below, soot and creosote contained. We’re not scattering dust through your living room.
- 5
Plain-English verdict. If the liner is fine, we say so and hand you the report. If something needs attention, we show you the video and quote you a real number. If it can wait a season, we tell you that too. If it needs doing, we’ll do it right. If it doesn’t, I’ll tell you that too.
- 6
Cleanup and the 90-Day Done Right Promise. The hearth is left cleaner than we found it, and every job carries our written promise: if it’s not right, one call brings Wendell back at no charge.

Why Brentwood Homeowners Call Top Hat Chimney for Gelco Work
Most of our Brentwood customers found us after a national chain burned them once. They don’t want a rotating crew in a different truck every year. They want someone who knows their specific fireplace, answers the phone, and stands behind the work. We’ve been doing this since 1999. Wendell grew up in San Diego, but he’s spent the better part of two decades hauling brushes up onto Brentwood rooftops, and he learned the trade properly at Southwestern College before chimney work took over. These days he’s the guy people call when they want a straight answer about whether the flue actually needs cleaning or whether someone just told them it did.
We work with Gelco units every season, and we also service DuraFlex and HeatShield systems, so when a Gelco part is discontinued or backordered, we know the right alternative that fits without compromising the warranty. Every technician is background-checked and shows up in uniform with a real arrival window. Seniors and veterans always get 10% off, no questions asked. Any repair over $200 takes $40 off. And if you’re inside our service county, there’s no trip charge.
Frequently Asked Questions
No. We’re an independent Gelco service provider, which means we’re not tied to factory pricing, factory parts delays, or factory scripts. We work on Gelco units because we see them constantly in Brentwood and we know them well, not because we’re on a manufacturer’s list. For chimney cleaning and sweeping, manufacturer authorization matters far less than hands-on experience with how these specific units behave after years of use.
A standard open fireplace with a Gelco unit runs $189 to $249 in Brentwood. Inserts and stoves run $229 to $289. You get the exact number on the phone before we book, and it doesn’t change when the sweep is standing in your living room. Call (934) 935-3847 for a firm quote.
Once a year, burn or no burn. Chimneys break in the off-season too. A Brentwood summer means humidity, and humidity plus old creosote means a smell that leaks into the house even when you haven’t lit a fire in months. The annual sweep keeps the flue clean and gives us a chance to catch small Gelco-specific issues, like a flattening door gasket or a damp chase top, before they turn into four-figure repairs.
No. And this is where the camera footage matters. Before we recommend any liner work on a Gelco system, you see the video of your own flue with your own eyes. If the liner is intact and your third-degree creosote hasn’t eaten through the mortar joints, we’ll tell you it can wait. If it can’t wait, you’ll see exactly why on the screen. The camera footage and a plain-English verdict, every time, no exceptions.
When the part is still made and the price is fair, yes. When Gelco parts are discontinued, which happens on older units, we source quality aftermarket options that match the spec. We’ll always tell you what we’re using and why, so you’re never guessing about what went into your fireplace. We also work with DuraFlex and HeatShield components when a Gelco liner needs replacement, because they fit correctly and hold up. Call (934) 935-3847 and we’ll talk through what your specific unit needs.
