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 Trust Top Hat Chimney for Your Gelco Chimney Cleaning?
Gelco liners and caps show up in a lot of Long Island chimneys, especially in postwar Capes and splits built between 1947 and 1970. Those homes often had oil-fired heat from day one. The flue was sized for one burner, the liner went in decades later, and somewhere along the line a Gelco cap got added. We’ve seen that exact stack hundreds of times.
Wendell learned the trade through the construction and building technology program at San Diego Mesa College, then put in well over a decade sweeping flues before he ever thought about running his own operation. He’s worked chimneys all across Long Island, from ranch houses in Levittown to older colonials near the Sound. That matters when you’re dealing with Gelco components because the brand’s galvanized steel behaves differently in a salty marine environment than it does inland. We know what to look for before a rust spot becomes a reline.
We’re background-checked, uniformed, and we answer the phone around the clock. The number you hear on the phone is the number on the invoice. If it doesn’t need fixing, we’ll tell you that first.
Common Gelco Chimney Cleaning Problems We Fix in Long Island
Gelco makes solid galvanized steel products, but Rockville Centre Gelco service calls are common because Long Island’s environment is unforgiving. Here’s what we find most often:
- Condensation corrosion at riser seams. Gelco 6-inch round liner kits use galvanized steel risers joined at seams. On exterior chimneys near the South Shore or along North Shore bluffs, salt-laden air settles into those seams and accelerates galvanic corrosion. We regularly find pinhole leaks at seam lines on systems less than a decade old. The fix is usually cleaning and sealing, not replacement, but you have to catch it before the metal thins.
- Creosote buildup at angled elbows. When a Gelco liner serves a wood stove or fireplace and includes 30- or 45-degree elbows, those bends trap smoke and cool it just enough for creosote to condense. In Levittown-era homes where a wood burner was added later, the liner is often oversized for the appliance, which makes the problem worse. Low flue temps mean more accumulation at every turn. A straightforward rotary brush sweep breaks it down, but only if the elbows are accessible.
- Warped spark arrestor mesh. Gelco spark arrestor assemblies use fine mesh to stop embers. On Long Island, prolonged sea spray rusts the mesh. A chimney fire warps it. Either way, the mesh pulls away from the frame and lets sparks through, which defeats the purpose. We replace these regularly, especially on barrier island homes where nor’easters push salt directly onto the cap.
- Loose cap mounting brackets. Gelco caps mount with steel brackets. Nor’easter winds and thermal cycling work those brackets loose over time. The cap starts to rattle, then shifts enough to let water in. By the time a homeowner hears it, the crown has usually been taking water for a season or two. Tightening is a short-term fix. We typically recommend stainless brackets to match the marine environment.
- Rust staining below the cap. When a Gelco galvanized cap begins to corrode, it sheds rust fragments that streak down the chimney crown and brick. This is cosmetic at first, but if you see it consistently after rain, the cap’s galvanized coating is failing. On Long Island, with salt in the air, that failure accelerates faster than the liner itself. Replacing the cap early saves the crown.
Gelco Parts & Our Repair-vs-Replace Approach
We recommend OEM Gelco caps and brackets when they’re available and in stock, because their galvanized coating is matched to the liner’s expected lifespan. Mixing a cheap uncoated steel bracket with a Gelco liner just creates a corrosion point. For discontinued Gelco parts, we use UL-listed stainless aftermarket equivalents. Stainless holds up better in Long Island’s salt air anyway, and we’ll tell you that plainly.
When a Gelco liner section is corroded, we look at the whole run before recommending relining. If the damage is isolated and the rest of the liner is sound, a section repair makes sense. If we find thinning at multiple seams or heavy pitting along the interior, full relining is the honest call. We show you the camera footage either way. The footage and a plain-English verdict, every time, no exceptions. Call (516) 968-5380 for a free estimate.
Our Gelco Service Process - Step by Step
- 1
Diagnosis. We camera-inspect the entire Gelco liner from cap to appliance connection. We’re looking for seam corrosion, creosote glaze at elbows, rust pinholes, loose brackets, and crown damage. You see the footage before we recommend anything.
- 2
Cleaning or repair. For cleaning, we match the brush to the liner diameter. Gelco 6-inch liners get a rotary brush suited to galvanized steel, not a stiff wire that scores the coating. For repairs, we install OEM Gelco parts where they exist, and UL-listed stainless aftermarket parts where they don’t.
- 3
Test. After any liner work, we run a draft test and check for leaks at every seam and adapter. For cap replacements, we verify the bracket torque and test the spark arrestor mesh integrity. If it rattles in a breeze, it’s not done.
- 4
Written guarantee. Every job, including Gelco cap installs and liner sweeps, carries the 90-Day Done Right Promise in writing. If it’s not right, one call brings Wendell and his crew back at no additional cost.
Gelco Products We Service & Install in Long Island
We service the Gelco products commonly found in Gelco repair in Brentwood and across Long Island: 6-inch round liner kits, 8-inch oval-to-round adapter systems, chimney cap and spark arrestor assemblies, and masonry repair flashing kits. Our truck stock includes common Gelco cap sizes, stainless mounting brackets, oval-to-round adapters, and flashing materials. If you need a specific Gelco part we don’t have on hand, we typically source it within a day or two from local supply houses. We also work with DuraFlex and HeatShield for homes where a different system makes more sense.
We Also Service These Brands
We’re not married to any one manufacturer. Alongside Gelco, we install and service DuraFlex and HeatShield products, plus components from Olympia Chimney, Famco, and Copperfield. When a liner brand no longer matches your appliance or your home’s exposure, we’ll recommend the switch and explain why in plain English.
FAQs - Gelco Chimney Cleaning Service in Long Island
No. We are an independent Gelco service provider. We have no manufacturer affiliation, which means we recommend what’s right for your chimney, not what a brand contract tells us to push. Wendell Pike has been servicing Gelco systems on Long Island for years, and his name goes on every job.
Because the cap sits exposed to Long Island’s salt-laden air and rain from every angle, while the liner is protected inside the flue. Galvanized coatings fail faster on exposed surfaces, especially near the South Shore and North Shore. We replace Gelco caps with OEM galvanized or stainless aftermarket equivalents matched to your home’s exposure. Call (516) 968-5380 and we’ll inspect it before it becomes a water entry point.
Yes. The Gelco 8-inch oval-to-round adapter is the transition point where creosote builds up most. We clean that section with brushes sized to each dimension and we camera-check the adapter joint afterward. The key is not forcing a 6-inch brush through the oval section. We clean the two diameters separately and verify the adapter seal.
No. A rattling Gelco cap usually means the mounting brackets have loosened from nor’easter winds and thermal cycling. It might just need tightening. Or the bracket may be corroded and near failure. Either way, don’t ignore it. A loose cap shifts, lets water in, and accelerates crown damage. We’ll tighten or replace the brackets and test it before we leave.
Not necessarily. Surface rust on the exterior of a Gelco galvanized liner doesn’t mean the interior is compromised. We camera-inspect the inside before recommending anything. If the interior coating is intact and the rust is cosmetic, we’ll clean it and tell you how long you can reasonably expect it to last. If there’s thinning or pinholes, we’ll show you the footage and give you repair-versus-reline options. Surface rust alone is not a reason to reline.
Gelco spark arrestor assemblies with properly installed mesh meet standard spark arrestor requirements for Nassau County when the mesh openings are sized correctly and the assembly is in good condition. The problem we see most often in Long Island is corrosion. A brand-new Gelco cap that meets code won’t meet it a few seasons later if the mesh has rusted and pulled away from the frame. We inspect mesh integrity on every cleaning and flag it when it’s no longer code-compliant. Call (516) 968-5380 for an exact quote. Estimates are free.
Most our Chimney Cleaning & Sweep services for Gelco liners on Long Island run between $180 and $340, depending on liner length, creosote condition, and accessibility. If your flue serves an oil burner rather than a wood fireplace, expect oil-burner flue cleaning with the sulfurous condensate that attacks clay and galvanized liners differently than wood creosote. Cap replacement and bracket upgrades are priced separately. We give you the number before any tool comes off the truck, and it’s the number on the invoice. Call (516) 968-5380 for a free estimate.
