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 Trumbull, CT | Hearthstone Chimney Co.
Chimney Cleaning & Sweep in Trumbull for Gelco systems typically runs $180-$340 for a standard sweep and inspection, with most jobs completed in a single visit. What sets our work apart in Trumbull is the town’s unusual concentration of 1960s-70s colonials with double-flue masonry chimneys converted from oil to natural gas - a combination that destroys Gelco dampers and caps faster than almost anywhere else in Fairfield County. We’re an independent shop, not a Gelco dealer, so our only obligation is fixing what’s actually broken. Call (475) 265-6822 for a free estimate.
Why Trumbull Residents Choose Us for Gelco Service
We’ve been running brushes through Trumbull chimneys for over 42 years. Russell Haines, our owner, learned the trade at Los Angeles Trade-Technical College before heading east and spending the better part of two decades on real jobs across the Shelton area, including the older colonials up near Huntington Center that tend to throw every problem at you at once. He knows Gelco hardware the way a mechanic knows an engine - which gasket hardens in freeze-thaw cycles, which cap mesh rusts first, when a liner joint is failing versus just needing a sweep.
Because we are an independent Gelco service provider - not manufacturer-affiliated or authorized - our recommendations follow the chimney, not a warranty program. We stock quality aftermarket Gelco-compatible gaskets, caps, and damper hardware that match OEM fit, and we source genuine Gelco components when a specific proprietary part is the only correct fix. Our technicians are background-checked and uniformed, and most jobs finish in one visit. The 90-Day Done Right Promise covers every job in writing, no arguing. A live person answers our phones 24 hours a day, every day.
Russell’s approach is straightforward: “Tell me what it is, fix what needs fixing, leave the rest alone.” That means photos you can see, a plain-English verdict, and no ticket-padding. Gelco sales & service is one of our core specialties, and Trumbull service area homes keep us busy every fall.
Common Gelco Chimney Cleaning Problems We Solve in Trumbull
- Gelco top-sealing dampers seized open from freeze-thaw moisture. Trumbull’s inland Fairfield County winters deliver repeated freeze-thaw cycles that are especially destructive to aging mortar joints and cracked flue tiles. Gelco dampers installed on 1960s-70s double-flue masonry chimneys absorb flue-gas condensate, the gasket warps, and the seal stays open year-round. You’re heating the neighborhood.
- Gelco caps clogged with ice debris and rusted mesh. Nor’easters regularly deposit ice and debris on chimney crowns across Trumbull. The mesh on Gelco single-flue and multi-flue caps rusts and clogs, the lid can lift, and suddenly birds and squirrels have direct access to that secondary flue you forgot about.
- Gelco stainless liners corroding at the tee joint in oversized oil-era flues. Most Trumbull colonials converted from oil to natural gas, which burns cooler and produces acidic condensate. In the now-oversized flue, that condensate pools at the bottom of the Gelco liner tee, corroding joint clamps and eating into the terra cotta surrounding them.
- Gelco multi-flue caps with uneven draft pulling creosote onto the cap underside. Trumbull’s double-flue colonials - one flue for the furnace, one for the fireplace - develop pressure imbalances. The Gelco multi-flue cap ends up with creosote condensation on its underside that drips straight back into the firebox, creating odor and staining.
- Secondary family-room fireplaces with Gelco dampers stuck open for a decade. In Trumbull’s split-levels and colonials, that basement or family-room fireplace hasn’t seen a fire since the kids were small. The Gelco damper is often stuck open, the flue full of leaves, nests, and standing rainwater. We find this constantly. It needs cleaning and damper repair before the heating season, not after.
Gelco Service in Trumbull: What Local Conditions Mean for Your Equipment
Trumbull underwent its primary suburban build-out in the 1960s and 1970s, leaving the town with a dense concentration of colonial and split-level homes whose masonry chimneys were originally sized for oil-fired furnaces. As the vast majority of these homes have since converted to natural gas - which burns cooler and produces acidic condensate - the now-oversized, often unlined furnace flues are chronically under-performing, creating accelerated moisture deterioration and creosote condensation that makes annual chimney inspection and cleaning a genuine safety necessity rather than a cosmetic service in Trumbull.
For Gelco equipment specifically, this means trouble. A Gelco stainless liner run through an oversized oil-era flue in a Trumbull colonial collects condensate at the tee that the liner was never designed to handle at that volume. The clamps corrode. The terra cotta behind them spalls. Meanwhile, the secondary fireplace flue’s Gelco top-sealing damper - the one in the family room you haven’t used since 2014 - has been breathing that same moist, acidic air. The gasket hardens. The seal fails. Come October, you light the first fire and wonder why the room smells like a wet campfire.
In the Nichols section of Trumbull we opened a Gelco top-sealing damper on a 1968 colonial’s family-room fireplace and found the gasket rock-hard and the seal stuck wide, with leaves and a bird nest packed against the mesh. We swept both flues, replaced the Gelco damper gasket and hardware, and reset the cap - the homeowner could finally close the flue before the first cold snap.
Gelco Models & Products We Service in Trumbull
We work on the full Gelco residential line: Gelco Top-Sealing Damper, Gelco Multi-Flue Chimney Cap, Gelco Stainless Steel Chimney Liner, and Gelco Single-Flue Cap. Each has its own failure pattern in Trumbull’s climate and housing stock.
Our trucks carry Gelco-compatible gaskets, mesh screens, lid assemblies, and liner hardware for same-day replacement on most calls. When a proprietary Gelco part is required - certain damper actuator mechanisms or specific liner collar configurations - we source genuine components and return to complete the job. We do not substitute builder-grade parts. If the masonry behind your Gelco liner or damper has failed, we’ll show you the photos and explain why replacing the appliance alone won’t solve the problem.
Gelco Service Pricing in Trumbull

FAQs - Gelco Chimney Cleaning in Trumbull
Usually just a part. In Trumbull’s freeze-thaw climate, the gasket hardens and the hinge hardware corrodes long before the damper frame itself fails. We replace the gasket, clean and lubricate the mechanism, and test the seal. If the frame is cracked or warped, we’ll show you why a full replacement makes sense. Call (475) 265-6822 and we’ll diagnose it on site.
Nor’easter ice and debris are the culprit, combined with rusting mesh on older caps. Trumbull’s mid-century crowns take direct hits, and the mesh on Gelco caps from the 2000s-2010s wasn’t always stainless. We replace with corrosion-resistant mesh and verify the lid tension so wind can’t lift it. An annual pre-winter inspection prevents mid-January surprises.
Annually, without exception. Trumbull’s oil-to-gas conversions created condensate conditions that accelerate corrosion at Gelco liner joints. The National Fire Protection Association recommends yearly Level 1 or 2 inspection for all active chimneys; in Trumbull’s housing stock, we’d push toward Level 2 with a camera every few years to catch what you can’t see from the firebox. Call (475) 265-6822 to schedule before burning season.
Yes. We routinely find Trumbull split-levels and colonials where the secondary family-room fireplace’s Gelco damper has sat open for a decade, turning the flue into a direct pathway for birds, squirrels, and standing rainwater. Light a fire without sweeping and inspecting first, and you’re risking a chimney fire or carbon monoxide backup. The cleaning also lets us verify the damper seals properly when you’re done burning. Call (475) 265-6822 for a free estimate.
We can service the liner itself - joint repair, tee resealing, section replacement - but cracked terra cotta behind a Gelco liner is a masonry problem, not an appliance problem. Replacing the liner alone won’t stop combustion gases from leaking through the tile gaps into your home. We’ll show you camera footage of the damage and explain whether the tiles need repair, parging, or full relining before the Gelco component goes back in. No work is recommended without photo evidence you can see for yourself.
