This page is for Fairfield homeowners with Gelco products installed - common in the Greenfield Hill colonials and the post-war splits near Tunxis Hill - who want the work done by technicians who know the difference between a Gelco Pre-Sealed Damper and a standard throat damper without being told.

How Gelco Products Fail - and How We Fix Them

• Gelco Pre-Sealed Damper (Model P/S series) - seal fatigue from Fairfield’s freeze-thaw cycles. The silicone bulb seal on these top-mounted dampers hardens after 8-12 winters of Connecticut temperature swings. We see this on Greenfield Hill homes where the damper sits exposed above a tall, unlined flue. Our fix: replace with OEM Gelco seal kit or upgrade to a Gelco Lyemance damper with a longer-lasting silicone compression seal. We test the seal with a smoke pencil before we leave.
• Gelco Multi-Flue Chimney Cap - salt corrosion at the base flange. Fairfield’s proximity to Long Island Sound means coastal salt accelerates galvanic corrosion where the cap’s stainless base meets a terracotta flue tile. The Gelco Multi-Flue cap with the .024″ 304 stainless hood holds up better than the .018″ economy version, but the base flange still pits. Our fix: fabricate a custom copper or thicker stainless base extension, or replace with a Gelco cap specified for marine environments. We photograph the flange before recommending either path.
• Gelco Stainless Steel Liner - creosote bridging at corrugated flex joints. Gelco’s corrugated flex liner (common in 1980s-1990s Fairfield relines) has more surface area than smooth-wall, so creosote accumulates at the corrugation peaks. This restricts draft and increases chimney fire risk. Our fix: rotary cleaning with polypropylene brushes sized to the liner’s inner diameter, never steel wire that scores the stainless. For heavy glazed creosote, we apply ACS Anti-Creo-Soot as a pre-treatment, then mechanical removal.
• Gelco Lyemance Damper - cable fraying from improper original routing. The Lyemance’s pull chain and cable assembly fails when the cable rubs against a sharp flue edge or when a previous installer used a generic cable clip instead of Gelco’s brass guide bushing. Fairfield’s older homes often have offset flues that make clean routing difficult. Our fix: reroute with Gelco’s OEM cable kit, install a proper guide bushing, and lubricate with high-temp graphite. If the flue is too offset, we sleeve the rub point with a stainless wear guard.
• Gelco Chimney Pot / Crown Wash - water intrusion behind the pot base. Gelco’s decorative chimney pots look sharp on Fairfield’s colonial revivals, but the bedding mortar cracks when the crown wash beneath it fails. Water gets behind the pot, freezes, and pushes the pot off-kilter. Our fix: remove the pot, rebuild the crown wash with CrownSeal or pour a new concrete crown with proper drip edge and slope, then re-bed the pot with high-temp refractory mortar. We check the flue gas clearance to the pot walls while we’re up there.

Our Gelco Chimney Cleaning & Sweep Process

1. 1
   Call and schedule. A live person answers, asks what Gelco product you have (if you know), and books a window. We confirm our $89 Seasonal Tune-Up or scope the repair if you’ve described symptoms.
2. 2
   Level 1 or Level 2 inspection on arrival. We determine which level based on what’s changed since last service. For a Gelco damper that’s not sealing or a liner with known creosote issues, we typically start with Level 2 - camera inspection from top and bottom, photos you can see on our tablet, plain-English verdict.
3. 3
   Parts decision. If we need a Gelco OEM part, we source from our regular supplier with typical 2-3 day turnaround. For common wear items (seals, cables, bushings), we stock quality aftermarket equivalents that meet or exceed Gelco spec. We explain the trade-off and let you choose.
4. 4
   The work. Background-checked, uniformed technicians complete most Gelco jobs in a single visit. Rotary cleaning for liners, seal replacement for dampers, crown rebuilds with proper cure time. If it’s not right, we don’t leave.
5. 5
   Testing and documentation. We run a smoke test or draft gauge check, show you the after photos, and leave a written report with our findings and recommendations ranked by urgency - what needs doing now, what can wait, what to watch.
6. 6
   The 90-Day Done Right Promise. Every Gelco job is covered in writing. If it’s not done right, we make it right. No paperwork to find, no arguing.
