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 Repair in West Hartford: What to Know First
We provide independent Gelco chimney repair in West Hartford, and most jobs are completed in a single visit with upfront pricing agreed before we start. Typical Gelco repairs run from $340 for targeted mortar repointing up to $2,800 for partial rebuilds with waterproofing, and we back every job with our 90-Day Done Right Promise in writing. This page is for homeowners who already know they have Gelco components in their chimney system and want a technician who understands how these parts age in Connecticut’s freeze-thaw climate, not a generalist who treats every brand the same. Call us at (860) 743-1516 for a free estimate with camera inspection and photo report included.
How Gelco Products Fail - and How We Fix Them
- Gelco Multi-Flue Chimney Caps (Model M-8, M-12 series): The 304 stainless mesh on these caps can separate at the weld points after 8-12 winters in West Hartford, especially on homes near the reservoir where wind-driven rain accelerates corrosion at the corners. We see this more often than we’d like on colonials along Farmington Avenue. Our fix: remove the cap, assess the flue walls beneath, and either re-weld with marine-grade stainless or source a compatible replacement from Copperfield if the frame itself has warped. We never leave a cap sitting loose - that’s how squirrels get in and water gets down.
- Gelco Top-Mount Dampers (Pre-2015 cast-aluminum throat assemblies): The cast-aluminum throat plates on older Gelco top-mount dampers develop pitting that prevents a full seal, and the silicone gasket hardens to something resembling plastic after a decade of summer heat and winter cold. Homeowners notice the damper “almost” closing or hear a whistle on windy nights. We replace the gasket with OEM Gelco spec or upgrade to a HeatShield-compatible damper plate if the frame is still square. In West Hartford’s older homes with shallow fireboxes, this matters more than people realize - an unsealed damper is an uninsulated hole in your roof.
- Gelco Single-Flue Caps with Leg Kits (L-series, common on 1980s-1990s brick chimneys): The adjustable leg brackets were designed for standard 12″-16″ flue tiles, but West Hartford has plenty of non-standard flues from the 1950s building boom. We’ve found legs overextended to 18″+ that stress-crack at the bend, letting the cap tilt and channel water directly onto the crown. We fabricate custom leg extensions from Copperfield stock or switch to a slip-fit base mount that doesn’t depend on the bracket geometry.
- Gelco Chase Covers (galvanized steel, pre-2008): These were sold as “lifetime” covers but the galvanized coating on pre-2008 production runs was thinner than advertised. In West Hartford’s oak-and-maple neighborhoods with heavy leaf fall, trapped moisture accelerates rust at the drip edges. We replace with Gelco’s current 24-gauge stainless spec or match with Olympia Chimney covers if the chase dimensions are odd. The key detail most crews miss: the cover must overhang the chase top by at least 1″ on all sides, or you’re just making a swimming pool.
- Gelco Chimney Pots (terracotta and concrete, T-series): The concrete blend in Gelco’s T-series pots is porous enough that West Hartford’s 40-60 freeze-thaw cycles per winter eventually spall the surface, especially on south-facing exposures where daytime thaw and overnight refreeze happen daily. We see this on homes near West Hartford Center with minimal tree cover. Our repair: remove the pot, parge the spalled areas with a HeatShield-compatible crown coat, and reinstall with a stainless steel base plate that isolates the pot from direct crown contact. If the pot is too far gone, we source architectural matches from Famco that keep the roofline consistent.
Our Gelco Chimney Repair Process
- 1
Call and schedule: A live person answers, 24 hours a day. We ask about your Gelco components if you know them - model numbers help, but “the cap with the mesh top” is enough to get started.
- 2
Level-2 camera inspection: Our technician arrives in uniform, background-checked, and runs a camera up the flue before touching a tool. You get photos you can see and a plain-English verdict: what’s wrong, what caused it, what happens if you wait.
- 3
Parts decision: We check Gelco OEM availability against our inventory of DuraFlex, HeatShield, and Copperfield equivalents. If OEM is back-ordered (common on discontinued M-series caps), we explain the aftermarket option and why it meets or exceeds the original spec. No surprises on the bill - the number on the estimate is the number on the invoice.
- 4
The repair: Most Gelco jobs finish in one visit. Repointing, cap replacement, damper gasket swaps - our trucks carry the inventory. For rebuilds, we stage materials and return within 48 hours.
- 5
Test and document: We run the camera again, test dampers for full seal, and water-test caps with a controlled spray. You get the photo report and the 90-Day Done Right Promise in writing before we pack up.
- 6
Cleanup and follow-up: We leave the work area cleaner than we found it. Russell Haines reviews every Gelco job personally - that notepad in his pocket gets filled with flue sketches and notes for the file.

Why West Hartford Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been answering the phone with a live person for over 42 years, and we plan to be here in thirty more - that changes how you treat a customer. Our 90-Day Done Right Promise means if it’s not right, we make it right: in writing, no arguing, no paperwork chase. Russell Haines and our technicians know Gelco’s product evolution because we’ve removed and replaced hundreds of these components across West Hartford, from the pre-2008 galvanized chase covers failing in Elmwood to the M-series caps hanging on by a weld in Buena Vista.
We work with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes, no guessing at compatibility. When Gelco OEM is the right call, we source it. When a HeatShield or Copperfield equivalent solves the problem faster and holds up longer, we tell you straight. Background-checked, uniformed technicians. Most jobs in a single visit. Photos you can see, a plain-English verdict. That’s the square deal.
FAQs
Gelco’s warranty on caps and dampers covers manufacturing defects, not wear from age or weather, and it does not require manufacturer-authorized service for valid claims. As an independent Gelco service provider, we document our work with photos and parts receipts so any legitimate warranty issue remains traceable. If your component is within the original warranty period and shows a clear defect, we’ll flag it and advise whether a warranty claim or our repair is the faster path. Call (860) 743-1516 and we’ll check the manufacturing date against Gelco’s coverage terms.
A Gelco stainless cap in 304 grade typically holds 15-20 years in West Hartford if the mesh is cleared of leaf debris annually; the pre-2008 galvanized chase covers average 8-12 years before rust-through at the drip edge. South-facing exposures with daily freeze-thaw cycling shorten that by 20-30 percent. We inspect cap condition during every sweep and tell you when replacement is two years out versus two months out. Call (860) 743-1516 to schedule - estimates are free.
We stock common Gelco caps, dampers, and gaskets, and we source OEM for discontinued lines when inventory remains in the supply chain. For back-ordered or obsolete parts - the pre-2015 cast-aluminum damper throats are increasingly scarce - we use DuraFlex, HeatShield, or Copperfield equivalents that meet or exceed Gelco’s original specifications. We explain which route we’re taking and why before ordering anything. No surprises on the bill. Call (860) 743-1516 for parts availability on your specific model.
Repair makes sense when the failure is isolated - a separated mesh weld, a hardened damper gasket, a spalled pot with sound base structure. Replace when the component has reached end of life and adjacent masonry shows matching deterioration, or when three or more repairs in five years indicate systemic issues. Our camera inspection shows you the difference: photos you can see, a plain-English verdict, and an honest call on whether work can safely wait. Call (860) 743-1516 for a free second opinion on any written estimate.
Most Gelco repairs - cap replacements, gasket swaps, targeted repointing - are completed in a single visit because our trucks carry the inventory. Jobs requiring custom fabrication or staged masonry (chase cover with odd dimensions, partial rebuild) typically finish within two business days of the initial call. We do not promise same-day dispatch because a proper inspection comes first, and rushing that step is how you get a callback. We’ve learned: do it right the first time, or plan on doing it twice. Call (860) 743-1516 to book - a live person answers, 24/7.
