Gelco Chimney Cap & Crown Nationwide

Gelco Chimney Cap & Crown in Fairfield: What to Know First

We provide independent Gelco chimney cap and crown service in Fairfield, with most inspections scheduled within a few days and repairs completed in a single visit when possible. A standard Gelco cap replacement runs roughly $340-$580 installed, while crown repair or coating typically falls between $450-$890 depending on accessibility and condition. We do not quote over the phone for crown work without looking, because a cap that looks fine from the ground can hide spalling concrete or a rusted flue collar that changes the job entirely.

Call (475) 251-7537

This page is for Fairfield homeowners who already own a Gelco product, or whose contractor installed one, and need honest guidance on whether to repair or replace. We are not affiliated with Gelco. We are an independent service provider who has worked on their products for years, including the multi-flue assemblies common in the Greenfield Hill and Stratfield neighborhoods where colonial and mid-century chimneys sit close to mature oaks that drop debris year-round. If you are unsure what cap or crown you have, we will identify it during inspection and show you photos before recommending any work. Call (475) 251-7537 to schedule. A live person answers, 24 hours a day.

How Gelco Products Fail - and How We Fix Them

• Gelco Multi-Flue Caps (Model 125 and 130 Series): The 125 and 130 series use a galvanized steel base with a stainless steel lid, and the galvanizing fails first at the corners where Fairfield’s freeze-thaw cycles concentrate. Water wicks into the seam, the base swells, and the lid no longer seats square. We see this on homes within two miles of the coast where salt air accelerates the galvanizing loss. We replace with a full stainless base or, if the flue spacing allows, upgrade to a Gelco stainless multi-flue cap that eliminates the dissimilar-metal problem entirely.
• Gelco Single-Flue Caps with Mesh Sides (Model 100 Series): The 100 series uses a roll-formed mesh that can separate at the crimp where it meets the cap skirt. Squirrels in the Lake Mohegan and Tunxis Hill areas exploit this gap, and once they are inside, the homeowner usually discovers the problem from the smell. We do not just bend the mesh back. We remove the cap, assess whether the mesh is fatigued or the crimp tooling has failed, and either re-crimp with proper throat clearance or replace with a Gelco cap using welded mesh construction.
• Gelco CrownSeal Applications on Existing Crowns: CrownSeal is a flexible coating, not a structural repair, and we see it misapplied on crowns with active cracks wider than one-eighth inch. The product flexes, but it cannot bridge a moving crack. In Fairfield’s climate, a crack that opens in January will pump CrownSeal off by March. We grind out active cracks, apply a bonding agent, and use CrownSeal only as the final weathercoat over sound substrate. If the crown is too far gone, we pour new concrete with proper drip edge and slope.
• Gelco Draft-Increasing Caps (Vacu-Stack and WindBeater Series): The Vacu-Stack relies on a precise venturi gap that clogs with creosote in wood-burning installations, and the WindBeater’s rotating turbine seizes after a few seasons of coastal grit. Fairfield homeowners with these caps often call because “the fireplace smokes when it never used to.” We inspect the cap function first, because a seized WindBeater or clogged Vacu-Stack creates exactly the same symptom as a blocked flue. Cleaning the mechanism sometimes suffices; replacement with a conventional Gelco cap is the honest call when the moving parts are worn beyond service.
• Gelco Custom Caps with Factory Powder Coat: Gelco offers custom sizing with a black or brown powder coat that looks sharp when new. The powder coat chalks and fades unevenly on south-facing exposures, which is most Fairfield chimneys given our roof orientations. More critically, once the powder coat is compromised, the underlying galvanized steel corrodes faster than bare stainless would because the coating traps moisture at holidays. We stock raw 304 stainless Gelco caps in common sizes and can order custom stainless with no coating if the homeowner prefers longevity over color match. The price difference is usually $80-$140, and the cap outlasts the roof.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, notes your Gelco model if you know it, and books a Level-2 camera inspection. We do not guess at scope over the phone.
2. 2
   Inspection with documentation. Our technician arrives in uniform, photographs the cap or crown from the roof and from inside the flue, and runs a camera to confirm flue condition. You see the photos and get a plain-English verdict before any work is proposed.
3. 3
   Parts decision. If replacement is needed, we verify whether your original Gelco part is still in production. Some 100-series sizes were discontinued in 2019; we source quality aftermarket equivalents from Olympia Chimney or Famco that match the flue specification and maintain proper draft. For active warranty claims, we use OEM Gelco parts and document the installation for your records.
4. 4
   Repair or replacement. Cap installs include proper storm collar and sealant. Crown work includes grinding, bonding, and either coating or pour with cure time respected. We test draft and water intrusion before leaving the roof.
5. 5
   Written guarantee and cleanup. Every job carries the 90-Day Done Right Promise in writing. We bag debris, run a magnet for fasteners, and leave the work area cleaner than we found it. If it’s not right, we don’t leave.
6. 6
   Follow-up. We call within two weeks on crown pours to confirm curing, and we keep your inspection photos on file for future reference.

Why Fairfield Homeowners Call Hearthstone Chimney Co. for Gelco Work

Fairfield homeowners have called us for over 42 years because we treat a chimney cap like what it is: the only thing keeping water, animals, and debris out of a system that vents fire into your home. Our technicians are background-checked, uniformed, and trained on Gelco specifics, not just “metal hats in general.” We carry DuraFlex and HeatShield materials as well, so when a Gelco cap failure reveals liner damage or when crown deterioration has compromised the smoke chamber, we handle it without calling a second contractor.

The 90-Day Done Right Promise governs every job: Krafted right, Every time, Your home first, Standing behind it. In writing, no arguing. Russell Haines and our crew have worked the older homes along Greenfield Hill long enough to know which chimneys were built with oddball flue sizes and which neighborhoods see the worst squirrel pressure. That knowledge saves time and prevents callbacks. We also answer the phone with a live person 24 hours a day, because a cap that blows off in a March storm does not wait for business hours.
