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 Franklin Square, NY | Top Hat Chimney
We provide independent Chimney Cleaning & Sweep - Franklin Square Gelco service across the area, and the biggest difference here is what we find before we even touch a brush: abandoned oil flues. Most homes in Franklin Square were built between 1945 and 1965, and when the furnaces switched from oil to gas, the old oil flue often just got left there. That open flue sitting inside your shared masonry chimney is where moisture, birds, and acidic residue collect, and it changes how we clean and inspect your Gelco liner. Call (516) 963-1068 and we’ll schedule a sweep with a Level 2 camera inspection you can watch yourself.
Top Hat Chimney has serviced Gelco liners and caps across Nassau County for over 29 years, since Wendell Pike founded the company in 1999. We know the Gelco sales & service side of the trade, and we know Franklin Square’s housing stock because we’ve been up on these roofs since before most of these oil-to-gas conversions even happened.
Why Franklin Square Residents Choose Us for Gelco Service
Gelco makes a solid 316Ti liner and a well-built cap, but the hardware is only half the equation. The other half is the person holding the camera. Wendell Pike and his crew have pulled enough damaged Gelco sections out of Franklin Square chimneys to know what the common failure looks like here: pitting from sulfurous oil residue, not the shiny creosote glaze you see on wood-burning flues. A national chain sends a stranger who may have never worked a postwar Cape Cod chimney. We send a sweep who has.
We’re an independent service provider, not authorized by Gelco. That independence matters on this block: when a Gelco 304 liner has a torn section, we don’t automatically quote a full replacement. If the rest of the liner is sound, we cut out the damaged portion and couple in a new section. You get a camera report showing exactly what we found. The number we quote on the phone is the number on the invoice, and every job carries the 90-Day Done Right Promise in writing. If it doesn’t need doing, Wendell will tell you.
Ask anyone on your street. We’ve been the local alternative to the bait-and-switch outfits since 1999, and you’ll find Top Hat’s name and license published in plain sight. No voicemail box. A live person answers at (516) 963-1068 so you can book your Gelco cleaning with someone who knows Franklin Square.
Common Gelco Chimney Cleaning Problems We Solve in Franklin Square
- Pitting and perforation of Gelco 304 liners from acidic oil residue. Franklin Square’s heating-oil legacy means decades of sulfurous, acidic soot baked into the flue walls. When a home converts to gas, the new exhaust is cooler and wetter, and it reacts with that old residue, eating into 304 stainless faster than anywhere else in Nassau. We find pits and pinholes that a visual inspection alone will miss.
- Torn or kinked Gelco flexible liner sections from improper original sizing. The 60-to-80-year-old masonry in Franklin Square shifts. Freeze-thaw cycles expand and contract the brick, and a liner that was sized too tight or pulled too hard during install kinks at the offset. We see this most often where a second flue was squeezed beside the original.
- Gelco cap mounting brackets loosened by nor’easter wind and rain. The salt-laden air off the South Shore does a number on cap fasteners. Wind-driven rain hammers the crown, works the bracket loose, and then water gets in at the flue collar. By late winter, we’re tightening or replacing Gelco cap brackets all over Franklin Square.
- Bird and debris blockage in Gelco multi-flue caps on abandoned oil flues. That open oil flue is a standing invitation for starlings and sparrows. They nest inside, pack debris against the underside of your Gelco multi-flue cap, and suddenly the active flue is drafting poorly. This is the single most common call we get in Franklin Square’s postwar Cape Cods.
- Flashing failure where the roof meets a heavily spalled brick face. Decades of maritime freeze-thaw cycles spall the brick around the roofline, and the flashing lets go right at that junction. Water runs down the outside of the Gelco cap and into the crown. It’s a flashing repair and a cap reseating, not a liner problem, but it presents exactly like one.
Gelco Service in Franklin Square: What Local Conditions Mean for Your Equipment
Here’s the fact that separates Franklin Square from Hempstead, Garden City, or Westbury: the dense grid of 1945-1965 Cape Cods and ranches here means more than 70% of local chimneys share a single masonry structure with an abandoned, uncapped oil flue. That’s not a guess. That’s what our Level 2 camera inspections show, house after house, block after block. An open flue inside a shared chimney funnels moisture straight past your active Gelco liner, and the sulfurous residue left from the oil-burning years attacks the stainless from the outside in. You could have a perfectly good Gelco 316Ti liner, but if the neighboring flue is open and uncapped, that liner is aging twice as fast as it should. We serviced a Gelco 304 liner in a Cape Cod on Fenworth Boulevard where the homeowner converted from oil to gas in 2009 and never touched the old flue. The acidic soot had pitted the liner wall, and our camera found a six-inch tear near the thimble. We cut out the bad section, coupled in a new Gelco-compatible segment, and capped the abandoned flue in the same visit. That’s the Franklin Square condition in a nutshell, and it’s the first thing we check on every Gelco cleaning here.
Gelco Models & Products We Service in Franklin Square
We clean and inspect every Gelco product line a Franklin Square home is likely to have: the Gelco 316Ti Stainless Steel Chimney Liner, the Gelco 304 Stainless Steel Flexible Liner, and both the Multi-Flue and Single-Flue Chimney Caps. For liner section replacements, we stock genuine Gelco components and complementary OEM-compatible connectors locally, so our Chimney Repair in Franklin Square doesn’t wait on a warehouse truck from New Jersey. If a section is too far gone, we’ll say so. If it can be cut, coupled, and made sound, we’ll do that and show you the camera footage proving the rest of the liner is intact. Our repair-versus-replace stance is simple: safety and longevity come first, not the parts invoice.

FAQs - Gelco Chimney Cleaning in Franklin Square
Because the old oil residue inside the flue reacts with the cooler, wetter exhaust from a gas furnace, and that acid attacks 304 stainless much faster than wood smoke ever would. In Franklin Square, where oil-to-gas conversions are the rule, we see this pitting pattern constantly. The fix is a thorough cleaning and a camera inspection to catch pits before they become holes. Call (516) 963-1068 and we’ll show you what’s actually happening inside your liner.
Yes, directly. An open, uncapped oil flue lets birds nest and moisture pour into the chimney structure, and that moisture migrates to the underside of your Gelco cap, loosening brackets and corroding the collar. In a shared masonry chimney, the abandoned flue is not separate from your active one. It’s a hole in the same brick box.
Sectional repair is often the right call. If the tear or pitting is localized and the rest of the liner is sound, we cut out the damaged segment and couple in a new Gelco-compatible piece. We’ll show you the camera footage first, so the repair you approve is the repair you needed. When the liner is perforated full-length or the heat shield is compromised, we’ll say so plainly and quote a full reline. Call for a free camera-based assessment, (516) 963-1068.
We may not be directly on the water, but Franklin Square is close enough for marine air to accelerate rust on fasteners and brackets. The bigger issue here is wind-driven rain from nor’easters hammering the crown, loosening Gelco cap mounting brackets, and letting water in at the collar. A loose cap sounds harmless. It’s how liner damage starts.
Often, yes. A multi-flue cap that spans the whole crown keeps water, birds, and debris out of the abandoned flue as well as the active one. In Franklin Square’s oil-converted Cape Cods, capping the unused flue is the single most cost-effective step you can take to protect your Gelco liner. We’ll tell you if your setup genuinely needs it. If it doesn’t need doing, we’ll tell you that too.
