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 Attleboro: What to Know First
We provide independent Gelco chimney repair in Attleboro, and most jobs are completed in a single visit with no-hassle upfront pricing agreed before we start. Typical Gelco repairs run $275-$1,850 depending on whether we’re repointing mortar, rebuilding a spalling crown, or replacing failed flashing on a multi-flue setup. We’re not affiliated with Gelco - we’re an independent service provider - which means we source the right parts for your specific model and fix only what actually needs fixing.
This page is for Attleboro homeowners who know they’ve got Gelco components on their chimney and want a technician who understands the difference between a Gelco Multi-Flue cap and a standard single-flue unit. If you’re seeing water stains on the ceiling near your fireplace, bricks shedding their faces, or mortar turning to sand, call us at (508) 545-9737. We’ll send a background-checked, uniformed tech with a camera and a plain-English verdict.
How Gelco Products Fail - and How We Fix Them
- Gelco Multi-Flue Chimney Caps - screen mesh failure. The stainless mesh on Gelco Multi-Flue caps can separate at the weld points after 8-12 years of Attleboro’s freeze-thaw cycles, especially on homes near the Ten Mile River where humidity sits higher. We see this every spring. We replace with OEM-grade Gelco mesh or, if the frame is still sound, fabricate a matching screen insert that costs less than full cap replacement.
- Gelco Single-Flue Caps - base seal deterioration. The silicone base seal on Gelco Single-Flue models hardens and cracks faster than the cap itself, creating a gap that funnels water straight down the flue. Homeowners often replace the entire cap when only the seal needs attention. We remove the cap, reseat it with fresh high-temp silicone, and test the draw - done in under an hour.
- Gelco chimney crowns - surface spalling from trapped moisture. Gelco’s pre-formed crown units are solid when installed correctly, but if the original installer skipped the expansion joint or used standard mortar instead of crown-specific mix, water wicks in and the surface flakes off in sheets. We grind back to sound material, apply HeatShield CrownSeal or rebuild with proper crown mix, and slope it so water runs off.
- Gelco chase covers - corner rust-through on galvanized models. Older Gelco galvanized chase covers installed in Attleboro’s 1980s and 1990s construction booms are hitting 30+ years. The corners pool water and rust from the inside out, often dripping onto the fireplace framing before the homeowner notices. We fabricate custom copper or stainless replacements, or source Gelco-compatible stainless chase covers with cross-breaks that prevent pooling.
- Gelco flashing kits - separation at the step-flue joint. Gelco’s standard flashing kits work well on straight runs, but on Attleboro’s older colonials with settled rooflines, the step flashing pulls away from the chimney shoulder. We don’t just caulk over it. We remove courses, install new step flashing woven into the shingles, and counterflash with copper or coated aluminum that matches the Gelco cap finish.
Our Gelco Chimney Repair Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask for your Gelco model number if you have it, the symptoms you’ve noticed, and we book a window that works.
- 2
Level-2 camera inspection. Our tech arrives uniformed and background-checked. We run a camera up the flue, photograph the exterior, and document mortar joints, crown condition, cap integrity, and flashing. You see the photos on the spot.
- 3
Plain-English verdict and upfront pricing. Russell Haines or one of our senior techs explains what’s wrong, what caused it, and what we recommend. The price we quote is the price on the invoice. No surprises.
- 4
Parts decision: OEM Gelco or quality equivalent. If your cap or component is still in production, we can source OEM Gelco. If it’s discontinued or the OEM lead time is unreasonable, we use professional-grade equivalents from Copperfield or Famco that match spec and won’t void any remaining warranty on adjacent components.
- 5
The repair and live test. We complete most Gelco repairs in a single visit. Afterward, we run a draft test, check for water intrusion with a controlled spray, and clean the work area.
- 6
Documentation and guarantee. You get photos, a written report, and our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork, no arguing.

Why Attleboro 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 isn’t a slogan - it’s in writing, and we don’t argue. If the Gelco cap we resealed leaks, or the crown repair doesn’t hold, we come back. The K.E.Y.S. code governs it: Krafted right, Every time, Your home first, Standing behind it.
Our technicians are background-checked, uniformed, and trained on Gelco’s specific product lines, but we also carry DuraFlex liner systems and HeatShield resurfacing materials. When a Gelco repair reveals a deeper issue - a cracked flue, deteriorated liner - we can handle it without calling in another contractor.
And we document everything. Photos you can see. A plain-English verdict. A square deal with no surprises on the bill.
The chimney doesn’t care what you paid for the house. It just needs to be right.
FAQs
No - if the work is done correctly by an independent Gelco service provider using OEM or equivalent parts. Gelco’s warranty covers manufacturing defects, not installation or wear. We use parts that meet or exceed Gelco spec, and we document what was replaced so any future warranty claim on the component itself remains clean. Call (508) 545-9737 if you want us to review your warranty paperwork before we start.
Most Gelco repairs are completed in a single visit of two to four hours. Crown rebuilds or chase cover replacements on taller Attleboro chimneys may require a second day for material curing, but we schedule consecutive days and you won’t be left with an open flue overnight. We don’t promise same-day dispatch, but we do promise we’ll be there when we say.
Many Gelco caps and components from the 1990s and 2000s are discontinued, but we fabricate compatible replacements or source equivalents from Copperfield and Famco that match the critical dimensions. We never install a part that doesn’t fit properly just because it’s what we have on the truck. If your model is obsolete, we’ll tell you before we quote and show you exactly what we’d use instead.
Replacement is only necessary when the structure itself is compromised - widespread brick spalling, liner collapse, or a shifted foundation. Surface issues like cap seal failure, crown cracking, or localized mortar deterioration are repairs. Our camera inspection shows you the difference. We don’t recommend replacement without photo evidence you can see for yourself, and we’ll tell you plainly when work can safely wait a season. Call (508) 545-9737 for a free estimate - we’ll give you an honest assessment either way.
Water intrusion through a failed Gelco cap or crown accelerates every other problem. In Attleboro’s climate, one winter of freeze-thaw cycling can turn a $400 cap reseal into a $1,600 crown rebuild. More critically, a compromised flue can allow carbon monoxide into living spaces or create a chimney fire risk from creosote buildup. That said, we don’t scare-sell. If the camera shows your issue is minor and stable, we’ll say so. Call (508) 545-9737 and we’ll tell you exactly where you stand.
