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 in Brentwood, NY | Top Hat Chimney
We provide independent Chimney Cleaning & Sweep in Brentwood for Gelco systems, and the one thing that separates our work here is knowing what oil-fired exhaust does to a Gelco cap over 50 years of Long Island winters. Most Brentwood homes built between the 1950s and 1970s run oil heat through aging clay tile liners, and a Gelco cap that’s corroded or shifted isn’t cosmetic, it’s letting acidic flue gas eat your crown and pull soot back into the house. Wendell Pike and our crew have been on Brentwood rooftops since 1999, and we’ll tell you straight whether the cap needs replacing or the flue just needs a brush. Call (934) 935-3847 for a free estimate.
Why Brentwood Residents Choose Us for Gelco Service
We’re a locally owned, owner-operated shop that’s worked the same Brentwood streets for over 29 years. Not a franchise that rotated in last spring. Gelco caps and liners are everyday equipment for us; we see them on Capes, ranches, and colonials from Wicks Road to the neighborhoods over near Brentwood State Park. Wendell grew up in San Diego and learned the mechanical side of the trade at Southwestern College in Chula Vista, but he’s spent the better part of two decades hauling brushes and rods up onto Suffolk County rooftops. These days he’s the guy people call when they want a straight answer about whether their flue actually needs cleaning or whether someone just told them it did. We stock common Gelco cap sizes right on the truck, so most repair calls wrap in one visit. If you need a deeper dive, our Gelco sales & service page covers the full parts picture.
Common Gelco Chimney Cleaning Problems We Solve in Brentwood
- Rust-through on the Gelco cap’s outer shroud. Salt-laden air from the Great South Bay sits on Brentwood rooftops year-round, and that marine moisture chews through galvanized shrouds faster than people expect. A rusted shroud lets rain and debris drop straight into the flue, hastening tile cracks.
- Loose or cracked Gelco cap screens. When the mesh loosens, birds and squirrels move in. We’ve pulled nests out of oil flues that were causing downdrafts and pushing soot back into the living room.
- Gelco multi-flue cap bases that warp under Brentwood’s summer humidity. The base plate loses its crown seal, water gets between the cap and the masonry, and freeze-thaw splits the crown edge in winter. This is the most common failure we see on Capes with shared oil and fireplace flues.
- Weakened cap legs and mounting bands. Long Island’s freeze-thaw cycles work the hardware loose over time. A shifting cap rattles in high winds and eventually lets the whole assembly sit off-center.
- Acidic soot deposits cracking 1960s-era clay liners. Orange-brown oily staining inside the flue is the telltale. It means the oil burner’s been over-firing or running rich, and the acid eats through standard-weight clay liners faster than wood ash ever would.
Gelco Service in Brentwood: What Local Conditions Mean for Your Equipment
Here’s the Brentwood-specific problem that rarely shows up in a generic Gelco guide. Nearly all of Brentwood’s postwar housing stock, block after block of Capes and ranches built from the 1950s through the 1970s, runs on oil-fired heat. Long Island has one of the highest per-capita rates of home heating oil use in the nation, and Brentwood sits right in the middle of that map. That means a Gelco cap’s primary job here isn’t keeping out rain. It’s containing acidic oil-flue exhaust that eats through mortar crowns if it spills back into the chimney chase. Wood ash is alkaline; oil condensate is sulfuric. The two wear nothing alike. When we inspect a Gelco installation on a Brentwood chimney, we’re checking for the oily residue pattern that tells us the cap has been failing for years in a way the homeowner could never see from the ground. On a street off Wicks Road last month, a 1960s Cape’s Gelco 6-inch round cap had rusted clean through at the base. The oil burner was backdrafting soot into the living room, and the acid-laced exhaust had already begun spalling the brick at the crown. We replaced the Gelco cap with an exact-fit OEM unit, repointed the top three courses, and finished with a crown coating so the same deterioration wouldn’t repeat.
Gelco Models & Products We Service in Brentwood
We install and service the full Gelco cap line that matters on Long Island: the 3-inch round cap, 4-inch round cap, 6-inch round cap, and the multi-flue cap base. For Gelco caps and chase covers, we use OEM Gelco parts whenever possible because the fit and screen mesh are specific to their base dimensions, and that tight fit is what keeps oil exhaust where it belongs. For non-Gelco components like flashings or crowns, we use top-tier aftermarket materials that match or exceed the original. We keep common Gelco cap sizes and chase covers stocked for fast turnaround across Brentwood, so you’re not waiting on a parts order while your flue stays exposed. Our full scope includes cap replacement, cap installation, and multi-flue cap work.
Gelco Service Pricing in Brentwood
Gelco cap work in Brentwood runs on a few factors: cap size, whether it’s a single flue or multi-flue base, the condition of the crown underneath, and how much masonry repair is needed once the old cap comes off. We quote a flat price before a single tool comes off the truck, and the number you hear on the phone is the number on the invoice. Every quote covers the full job, not a teaser rate. Here’s where the line items land:
| Service | Price |
|---|---|
| Gelco cap replacement | Free estimate; quote on inspection |
| Gelco cap installation | Free estimate; quote on inspection |
| Multi-flue cap installation | Free estimate; quote on inspection |
We don’t publish a one-size price because a cap on a clean crown is a different job than a cap on a crown that needs repointing. Call (934) 935-3847 and Wendell or one of the crew will give you an exact number before we schedule anything. Estimates are free. There’s no trip charge inside Suffolk County, and we always knock $40 off any repair over $200. Seniors and veterans get 10% off, always.

FAQs - Gelco Chimney Cleaning in Brentwood
Because Brentwood sits close enough to the Great South Bay that salt-laden, high-humidity air is the baseline, not the exception. That marine moisture accelerates corrosion on galvanized cap shrouds, especially at the base where the cap meets the crown. Homes further inland in Suffolk County simply don’t see the same rate of rust-through. If your Gelco cap shows flaking or orange streaking, call (934) 935-3847 and we’ll tell you if it’s cosmetic or structural before you spend a dollar.
Yes, that’s exactly what the multi-flue cap base is designed for, and it’s the right call on the shared-flue configuration common in 1950s and ’60s Capes. The critical part is the seal between the base and the chimney crown. If that seal fails, water and acidic exhaust get between the flues. We check the base flatness and crown condition before we install, because a multi-flue cap on a spalled crown is just a new cap with an old leak.
Listen for scratching in the flue, especially in early morning. Look for nest material at the bottom of your fireplace or around your oil burner’s draft hood. A loose Gelco screen is an open door for starlings and squirrels, and a nest in an oil flue backs combustion gases into the house. If you’re hearing anything at all, call us at (934) 935-3847. We’ll pull the cap, show you the camera footage, and fix it right.
Often yes. That summer odor is usually acidic oil-flue residue wicking back through a shared chimney chase when the burner cycles less. A failed Gelco cap lets humidity and exhaust mix inside the flue, and the smell follows the path of least resistance. Correct cap fit and a sealed crown solve most of it. If the liner itself is glazed with third-degree creosote, that’s a different conversation, and we’ll show you the camera proof either way.
Not automatically. If the Gelco cap’s shroud, screen, and legs are intact and the mounting hardware is sound, we can reset the existing cap over a freshly repointed crown as part of our Brentwood Chimney Repair service. If the base has rusted through or the screen is compromised, replacement is cheaper than trying to patch a cap that’s already failing. We’ll give you a plain-English verdict, with camera footage, and tell you if the old cap can safely wait. Call (934) 935-3847 for an exact quote, and as Wendell says, “If it needs doing, we’ll do it right. If it doesn’t, I’ll tell you that too.”
