Gelco Chimney Cap & Crown Nationwide

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

We provide independent Gelco chimney cap and crown service throughout Attleboro, from single-flue cap replacements on ranch-style homes near Hebronville to multi-flue installations on the older colonials along the Woodcock Reservoir corridor. Most Gelco cap and crown jobs are completed in a single visit, with no-hassle upfront pricing agreed before we start. We’re not the cheapest outfit in town, and we don’t try to be - we quote the number you’ll see on the invoice, and we stand behind the work with our 90-Day Done Right Promise in writing.

Call (508) 545-9737

This page is for Attleboro homeowners who already have Gelco products on their chimney or are considering them, and want a technician who knows the difference between a Series A and a Series L cap without reading the label twice. If that’s you, call us at (508) 545-9737. A live person answers, any hour.

How Gelco Products Fail - and How We Fix Them

• Series A single-flue caps: The 18/8 stainless mesh on these is solid in theory, but in Attleboro’s freeze-thaw cycles the spot-welded corners fatigue after seven to ten years. We’ve replaced dozens on homes near Capron Park where the mesh has separated from the frame, letting squirrels nest directly above the flue. We fit a new Gelco Series A or, if the flue tile is oversized, a quality aftermarket equivalent with fully welded seams.
• Series L multi-flue caps: These cover multiple flues on a single crown, and the failure point is almost always the mounting skirt. The factory screws are 304 stainless, which galls against the aluminum skirt in coastal Massachusetts humidity. On a job last winter off County Street, we found three of four screws frozen solid and the skirt lifting in the wind. We drill out the old hardware, seal the skirt with a butyl-based flashing compound, and upgrade to 316 stainless fasteners that won’t seize.
• Series C copper caps: Beautiful when new, but the soldered seams on pre-2015 units crack where the crown slope meets vertical walls. Copper work-hardens with thermal cycling, and Attleboro’s temperature swings from single digits to sixty in March are hard on it. We don’t patch copper - we remove the cap, re-solder with 95/5 tin-silver, or replace with a new Series C if the metal is too thin.
• Gelco crown coating failures: The CrownSeal product is good material, but it fails when applied over a crown that’s already spalled or when the prep skips the bonding wash. We’ve stripped and re-coated crowns on Pleasant Street homes where a previous contractor painted over active cracks. Our prep: wire brush to sound concrete, mist with water, apply CrownSeal in two passes to the specified thickness.
• Multi-flue cap sizing errors: The Series L comes in stock sizes, and a surprising number of chimneys in Attleboro’s 1920s housing stock need something between catalog dimensions. A cap that’s even an inch short on one side creates a drip line that erodes the crown in three to five years. We measure with a story pole, not a tape measure held in the air, and we order custom-fabricated Gelco caps when stock won’t do.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers at (508) 545-9737, 24 hours a day. We book a window that works for you, not a four-hour guessing game.
2. 2
   Level-2 camera inspection. Before we touch the cap or crown, we run a camera up the flue. Russell Haines started doing this after finding too many cracked liners hidden beneath a perfectly good-looking cap. You see the photos; we explain what they mean in plain English.
3. 3
   Parts decision. If your Gelco cap is salvageable, we say so. If it needs replacement, we source OEM Gelco or a quality aftermarket from our inventory - we also carry DuraFlex and HeatShield materials for related repairs. We explain the trade-offs and the price difference before you decide.
4. 4
   The repair. For crown work, we cut back to sound material, prep the surface per manufacturer spec, and apply coating or pour new concrete as needed. For cap replacement, we verify flue tile condition, set the new cap with proper clearances, and secure it with hardware rated for the application.
5. 5
   Test and document. We run another camera pass to confirm nothing shifted during the work. You get photos, a written verdict, and our 90-Day Done Right Promise - in writing, no arguing.
6. 6
   Cleanup and close. We haul away the old cap and debris. The number on your estimate is the number on your invoice.

What Gelco Chimney Cap & Crown Costs in Attleboro

These are real ranges for Attleboro homes we’ve worked on in the past two years. Your exact price depends on access, crown condition, and whether we find related issues during inspection.

What moves the price: height and roof pitch (we don’t do steep roofs without proper fall protection), crown square footage, whether the flue tile needs repair before capping, and if we’re matching existing copper rather than switching to stainless. We don’t recommend anything without camera evidence you can see for yourself, and we’ll tell you straight when work can safely wait.
