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.

That’s the job Smithtown keeps handing us.

Call (631) 502-3612 for a free estimate.
Why Smithtown Residents Choose Us for Gelco Service
Gelco liners are good stainless steel, but they live inside chimneys that were built when Eisenhower was president. In Smithtown, that means terra cotta flue tiles spalling behind the liner, mortar joints gone soft from decades of nor’easter moisture, and divider tiles cracked between the fireplace flue and the oil-burner flue. We’ve pulled enough Gelco liners out of Smithtown chimneys to know exactly what fails and where. Wendell learned the trade at Southwestern College in Chula Vista and has spent the better part of two decades running crews through Suffolk County. When it comes to Gelco sales & service, we’re the local crew that knows the liner and the chimney it sits in.
We stock common Gelco liner sizes and equivalent-quality stainless top plates, rain caps, and hangers locally, so a Smithtown job doesn’t wait on a parts truck from out of state. Every job is backed by our 90-Day Done Right Promise in writing. One call brings Wendell back.
Common Gelco Chimney Cleaning Problems We Solve in Smithtown
- Cracked divider tiles in double-flue chimneys. In Smithtown’s classic cape cods, one masonry chimney often serves both the fireplace and the oil burner, separated only by a shared terra cotta divider. When that tile cracks, oil-burner exhaust etches the outside of the Gelco liner in the fireplace flue. We see this regularly in this housing stock.
- Condensate pooling in oversized voids after gas conversion. A Gelco 5-inch liner hung in a 7-inch masonry void after a gas conversion collects acidic condensate, which pits the liner from the inside out. This is a standard Smithtown fuel-conversion problem now that National Grid keeps extending gas service along Main Street and Jericho Turnpike.
- Nor’easter moisture tracking through failing crowns. Wet snow and coastal wind work through cracked crowns and down the outside of the liner, corroding the vertical seams where the liner passes through the smoke shelf. Long Island’s nor’easters make crown work a regular part of liner service here.
- Kinked or sagging liners from unsupported spalled tiles. When the original terracotta flue tiles crack and shift behind a Gelco liner, the metal sleeve loses its support and kinks or sags. We find this all the time in Smithtown chimneys that have gone 60-plus years without a rebuild.
- Liner-to-appliance misalignment after fuel conversion. A Gelco rigid liner sized for an oil burner almost never matches the smaller BTU output of a new gas boiler. The misalignment stresses joints and lets condensate sit where it shouldn’t.
We repair first. If the metal is fatigued beyond patchable limits or the flue size is wrong for a gas conversion, only then do we recommend a full Gelco liner replacement. If it does not need doing, we will be the first ones to tell you.
Gelco Service in Smithtown: What Local Conditions Mean for Your Equipment
Here’s a fact specific to Smithtown that doesn’t apply the same way in neighboring towns: Smithtown’s building permit records show a steady wave of oil-to-gas conversions since National Grid extended service along Main Street and Jericho Turnpike, and in those jobs, an existing Gelco rigid liner sized originally for an oil burner almost never matches the smaller BTU output of a new gas boiler. The old liner hangs in a too-large void, condensate pools, and the metal starts corroding from the inside. Our Level 2 inspection report becomes the trigger for a Gelco liner swap the homeowner didn’t expect. That’s not a line we feed people to sell a liner. It’s what the camera shows, and we hand you the footage and a plain-English verdict every time. We work throughout Smithtown, from the streets off Edgewood Avenue out toward the Smithtown service area we’ve covered for over two decades.
On a 1963 split-level off Edgewood Avenue, our tech pulled the rain cap and found a Gelco 7-inch flexible liner crimped inward about six feet above the fireplace smoke shelf. The original oil-burner flue had been converted to gas with a 5-inch Gelco liner hung in the 7-inch masonry void, and condensation from the oversized cavity had started pitting the outside of the liner. We reused the homeowner’s existing Gelco top plate but sleeved the entire 5-inch liner with a fresh Gelco smooth-wall of the same diameter, adding a stainless multi-flue cap to stop the nor’easter-driven water that had been tracking down through the crown. That’s the kind of repair that only comes from actually looking at what’s inside the chimney, not quoting from a service menu.
Gelco Models & Products We Service in Smithtown
We work on Gelco 5-inch, 6-inch, 7-inch, and 8-inch smooth-wall flexible stainless liners, plus rigid liner sections and the components that go with them. We install genuine Gelco liner kits and components when they can be sourced locally, but for hangers, top plates, and rain caps we often use equivalent-quality stainless aftermarket parts that match the original Gelco dimensions. It’s the same metal, the same fit, and we’ll tell you which is which before we put anything in your chimney. If a Gelco liner shows sectional corrosion or liner-to-appliance misalignment, we repair first. Full replacement only happens when the metal is fatigued beyond patchable limits or the flue size is wrong for a gas conversion. We also handle chimney rebuilding, mortar repointing, and Level 2 inspections on Gelco-equipped chimneys of every era in Smithtown, plus our Chimney Repair in Smithtown.
Gelco Service Pricing in Smithtown
What you pay for Gelco chimney cleaning or liner service in Smithtown depends on what we find inside the flue. A straightforward sweep and inspection costs less than a liner repair, and a liner repair costs less than a full Gelco replacement. The number you hear on the phone is the number on the invoice. No trip charge inside the county, and we’ll do a free second opinion on any written estimate you’ve already got. We always give upfront pricing before a single tool comes off the truck. Call (631) 502-3612 and Wendell or the sweep who shows up at your door will walk you through exactly what the job involves and what it costs.

FAQs - Gelco Chimney Cleaning in Smithtown
Yes, because the liner is only half the story. The terra cotta flue behind it has been through 60-plus years of freeze-thaw and nor’easter moisture, and cracked or spalled tiles are common in this housing stock. We inspect the liner and the masonry around it, and we show you the camera footage so you can see what we see. Call (631) 502-3612 for an inspection in Smithtown.
Rarely, and we’ll tell you if you can. An oil-burner-sized Gelco liner almost never matches the smaller BTU output of a new gas boiler, and that mismatch lets condensate pool and eat the metal. If the liner is sound and the flue size is right, we’ll say so. Most Smithtown conversions we inspect need a liner swap, and that’s exactly what the National Grid gas extensions along Main Street and Jericho Turnpike are putting on our schedule week after week. Call (631) 502-3612 for a straight answer before you convert.
Not if the crew knows what they’re doing. We protect the liner while we rebuild the crown, and we check the liner where it passes through the smoke shelf for corrosion the old crown may have caused. In Smithtown, nor’easter moisture tracking through a cracked crown is one of the most common ways a Gelco liner starts to fail at the vertical seams.
Freeze-thaw works on the masonry around the liner, not the stainless itself directly. But as the mortar joints open and the crown cracks, water gets behind the liner and corrodes it from the outside. Proximity to the Sound moderates the cold but doesn’t stop the cycle, and the wet snow from nor’easters keeps the water coming. That’s why we always inspect the crown and mortar when we clean a Gelco liner in Smithtown.
In most Smithtown double-flue chimneys, yes. A multi-flue cap keeps nor’easter-driven water from tracking down through the crown and into the void around both liners, and it stops the cross-contamination that happens when a cracked divider tile lets oil-burner exhaust into the fireplace flue. Call (631) 502-3612 and we’ll tell you if your current cap is doing the job.
