Gelco Chimney Cap & Crown Nationwide

Gelco Chimney Cap & Crown in West Hartford: What to Know First

We provide independent Gelco chimney cap and crown service in West Hartford, with most Gelco cap replacements and crown repairs completed in a single visit. Our upfront pricing means the estimate we give over the phone or on-site is the number on the invoice. Gelco makes a solid product, but no cap lasts forever in New England’s freeze-thaw cycle, and no crown coating holds up indefinitely without honest inspection.

Call (860) 743-1516

This page is for homeowners who know they’ve got Gelco hardware on their chimney and want a technician who understands the difference between a Series A multi-flue cap and a Series L single-flue unit - without being sold a full rebuild they don’t need. If you’re seeing rust streaks, water in the firebox, or mortar crumbs on your roof, call (860) 743-1516. We’ll send a camera up, show you what we see, and tell you straight whether the fix is a cap swap, a crown coat, or something more.

How Gelco Products Fail - and How We Fix Them

• Series A multi-flue caps with clogged mesh screens. The 3/4-inch mesh on older Series A units traps cottonwood seed and West Hartford’s heavy maple samaras every spring. Water backs up, freezes in the collar, and splits the seam. We pull the cap, clean or replace the mesh with stainless 5/8-inch if the homeowner burns frequently, and reseal the collar with high-temp silicone rated for the Gelco expansion spec. Done right, not patched.
• Series L single-flue caps with corroded base flanges. The 304 stainless flange on pre-2015 Series L caps develops crevice corrosion where it seats against the flue tile, especially on south-facing chimneys in West Hartford that see daily sun and nightly dew. We catch this during camera inspection - the flange looks fine from the roofline but is paper-thin at the contact point. Our fix: flange replacement with 316L stainless where salt exposure is a factor, or full cap replacement if the lid geometry is compromised.
• Gelco crown coats that delaminate from thermal shock. Gelco’s CrownSeal is a good product, but it fails when applied over a crown that wasn’t properly prepped - still damp, or with active hairline cracks left unchased. We’ve re-coated dozens of West Hartford crowns where the previous contractor skipped the grinding step. We grind to sound concrete, prime with CrownSeal bonding agent, and build to 1/4-inch thickness minimum. It holds.
• Series C custom caps with improper overhang. The Series C line looks sharp with its rolled edges, but if the overhang is spec’d too short for a wide chimney shoulder, water runs behind the cap and erodes the crown underneath. We measure the shoulder width against Gelco’s own installation manual - which many installers have never read - and spec the correct overhang or recommend a drip-edge modification. Russell Haines has redrawn the flue diagram on his notepad more than once to show a homeowner exactly where the water’s getting in.
• Multi-flue caps with failed storm collar seals. Gelco’s multi-flue units rely on a storm collar where the cap skirt meets the flue projection. After fifteen to twenty Connecticut winters, the butyl sealant hardens and cracks. Water doesn’t always show inside immediately - it soaks the brick first. We remove the collar, inspect the flue wall for spalling, and reseal with a fresh butyl tape and mechanical fastening that exceeds the original spec. No guesswork.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, 24 hours a day. We ask about your chimney age, the Gelco model if you know it, and what you’re seeing - water, debris, rust, or draft problems.
2. 2
   Level-2 camera inspection. Our technician arrives in uniform, runs a camera up the flue, and photographs the crown, flue walls, and cap underside. You see the images on the screen. We explain what needs fixing, what can wait, and what doesn’t make sense to do.
3. 3
   Parts decision. If your cap is salvageable, we say so. If it needs replacement, we source Gelco OEM or equivalent-grade aftermarket - your choice, with the trade-offs explained. We keep common Gelco sizes in stock for same-visit completion.
4. 4
   The repair. Cap replacement, crown grinding and coating, or collar reseal - done with professional-grade materials, documented with before-and-after photos. Most Gelco jobs finish in two to four hours.
5. 5
   Testing and cleanup. We verify draft, check for leaks with a water test on crown work, and leave the roof and hearth cleaner than we found them.
6. 6
   Written guarantee. The 90-Day Done Right Promise, in writing, no arguing. If it’s not right, we come back. That’s the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.
