Call (475) 265-6822

Shelton’s hillside neighborhoods - from Huntington Center down to the Birmingham waterfront - put Gelco chimneys through a stress test that flatter towns don’t replicate. Hilltop homes catch wind that drives rain past aging damper seals. Valley-floor houses trap humidity that corrodes stainless cap welds from the inside out. We’ve pulled apart enough Gelco units in this town to know the difference. Russell Haines, our owner, learned this trade at Los Angeles Trade-Technical College before spending two decades running brushes through Shelton’s chimneys, including those stubborn older colonials near Huntington Center that throw every problem at once. He doesn’t pad tickets. He tells you what needs fixing and what doesn’t.

Why Trust Hearthstone Chimney Co. for Your Gelco Chimney Cleaning?

We’ve repaired hundreds of Gelco top-sealing dampers, multi-flue caps, and fireplace inserts across the Naugatuck Valley. That repetition matters. When a Gelco damper handle snaps or a cap weld cracks, we don’t guess at the cause. We’ve seen it before. We know the part number, the torque spec, and whether the fix lasts another season or another decade.

We’re an independent chimney service - not affiliated with or authorized by Gelco. We source our own parts, which means we can mix genuine Gelco gaskets with quality aftermarket stainless hardware when OEM stock runs thin. This keeps your repair moving without waiting on factory backorders. Our technicians are background-checked and uniformed, and most Gelco jobs finish in a single visit because we stock what breaks.

Every inspection ends with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your Gelco insert firebox has cracked rear bricks from over-firing, we show you the photo and explain whether it needs immediate attention or can wait until next season. Russell’s approach is straightforward: “Tell me what it is, fix what needs fixing, leave the rest alone.” That’s how we’ve operated for over 42 years.

Common Gelco Chimney Cleaning Problems We Fix in Shelton

• Top-sealing damper gaskets harden and crumble. Gelco’s rubberized damper seals don’t last forever in Shelton’s freeze-thaw cycle, especially on hilltop homes where wind chill drives temperatures lower than the valley floor. Once the gasket flakes away, warm air escapes up the flue all winter and rain seeps down during spring storms. We pull the damper, clean the frame, and install a fresh Gelco-spec gasket that seats properly.
• Stainless multi-flue caps corrode at weld points. Gelco’s multi-flue caps hold up well, but the mounting legs and seam welds take a beating in Shelton’s humid river-valley air. Fog rolls up from the Housatonic and sits in those crevices. We’ve found caps with pinholes at the welds that drop leaves and squirrel debris straight into the flue. We replace with quality stainless hardware or source a direct-fit Gelco replacement when the original is too far gone.
• Insert fireboxes crack at the rear brick panel. Gelco fireplace inserts in Shelton’s 1960s-1980s raised ranches often get over-fired by owners chasing more heat. The rear firebrick cracks, then heat reaches the steel wrapper and the chimney structure behind it. We replace with proper fire-rated brick or recommend a full insert evaluation if the damage has progressed.
• Firebox grates warp from thermal stress. Gelco cast-iron and steel grates sag in the middle after years of hot fires. A warped grate sits unevenly, which causes incomplete combustion and more creosote buildup. We stock replacement grates that match Gelco specs, or we can source OEM if the original pattern is still available.
• Damper handles seize or snap from creosote buildup. The pivot pins and frame on older Gelco dampers collect soot until the mechanism won’t budge. Homeowners force it. The handle breaks off in their hand. We disassemble the frame, clean the pins with rotary tools, lubricate with high-temp compound, and replace the handle if it’s already cracked. Last winter in Shelton, a homeowner called because their Gelco top-sealing damper wouldn’t close and cold air poured down the flue. Our tech pulled the damper, found a rock-hard gasket and a bent linkage arm, installed a new Gelco-spec gasket and handle, and swept the flue of the glazed creosote that had built up from smoldering fires. The damper sealed tight and the fireplace drew correctly on the next burn.

Gelco Parts & Our Repair-vs-Replace Approach

We keep genuine Gelco damper gaskets, handles, and cap hardware on the truck because those are the parts that fail predictably. When Gelco discontinues a part - and they do, especially for inserts from the 1990s - we switch to quality aftermarket stainless caps and firebrick that meet or exceed original specs. No builder-grade substitutes.

Our rule is simple: rebuild when it makes sense, replace when it doesn’t. A Gelco damper with a cracked gasket and solid frame gets a new seal and handle. A damper with a warped frame and frozen pivot gets replaced entirely. We’ll show you both options, explain the price difference, and let you decide. No upselling. A square deal: no surprises on the bill. Call (475) 265-6822 for an honest assessment of your Gelco unit.

Our Gelco Service Process - Step by Step

1. 1
   Diagnosis with camera inspection. We run a Level-2 camera up the flue to document creosote buildup, liner condition, and any debris from a failing Gelco cap. You see the photos. We explain what they mean in plain English.
2. 2
   Repair or install with Gelco-compatible parts. We pull the damper, replace the cap, or rebuild the insert firebox using the parts we’ve stocked specifically for Gelco units. Most jobs complete in one visit.
3. 3
   Combustion and draft test. After any Gelco damper or insert work, we verify draft pressure and check for spillage at the firebox opening. A Gelco top-sealing damper must seal tight when closed and open fully when the chain pulls - we test both positions.
4. 4
   Documentation and warranty. You get photos, a written verdict, and our 90-Day Done Right Promise in writing. If something isn’t right, we come back. No paperwork to file, no arguing.

Gelco Products We Service & Install in Shelton

We work on Gelco top-sealing damper systems, stainless multi-flue chimney caps, fireplace inserts and glass door sets, and cast-iron and steel firebox grates. For Shelton’s 40-60 year old chimney stock, we see a lot of original Gelco dampers that are due for gasket replacement and caps that have weathered two decades of hillside wind. We stock the common failure parts locally, so you’re not waiting on a warehouse shipment while burning season slips away.

We Also Service These Brands

We’re not a single-brand shop. Our crews also install and repair DuraFlex liner systems and apply HeatShield cerfractory flue coatings when a Gelco insert needs a relined chimney to perform safely. Multi-brand capability means we match the right product to your chimney’s condition, not force a one-size-fits-all fix.
