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.
Gelco Chimney Liner & Rebuild in Attleboro: What to Know First
As an independent Gelco service provider, we handle chimney liner and rebuild work for Gelco systems in Attleboro homes, typically completing most jobs in a single visit with upfront pricing agreed before we start. Gelco’s stainless steel and flexible liner lines are solid products when installed correctly, but we’ve seen enough of them in Attleboro’s older housing stock to know where they tend to fail after fifteen or twenty years of seasonal heating cycles. If you’re seeing water in the firebox, hearing metal flue noise, or your sweep flagged a liner issue on a recent inspection, call us at (508) 545-9737. We’ll send a technician with a camera, show you what we’re seeing, and quote the work honestly.
How Gelco Products Fail - and How We Fix Them
- Gelco UL-listed flexible liners in 6″ and 8″ diameters - common in Attleboro’s 1950s-1970s ranch and split-level retrofits - can develop circumferential crease cracks where the flex sections were over-compressed during original installation. The corrugations fatigue faster near the smoke chamber where temperatures spike. We cut back to sound metal and splice in a new Gelco flex section or, if the damage is extensive, upsize to a rigid Gelco stainless liner that eliminates the flex point entirely.
- Gelco’s older 316-alloy rigid liner systems, often found in the colonials along County Street and the Woodcock Reservoir corridor, sometimes show intergranular corrosion at the lower flue joints. Attleboro’s position in the Blackstone Valley means acidic condensation from long, cold shoulder seasons eats the weld seams from the inside out. We pull the compromised sections, inspect the surrounding masonry for spalling, and reinstall with Gelco’s current 316Ti alloy or a DuraFlex equivalent if the chimney geometry demands it.
- Gelco top-sealing dampers integrated with liner tops - the GTD series - suffer cable fray and frame distortion after a decade of freeze-thaw. The damper won’t seal, and the liner top loses its rain cap integrity. We replace the damper mechanism with OEM or a Famco equivalent, reseat the liner collar, and verify draw with a smoke test before we leave.
- Gelco liner collars and top plates in salt-air exposure - Attleboro isn’t coastal, but homes near the Ten Mile River basin see enough humidity that 304-grade hardware surface-rusts while the 316 liner body stays clean. We swap to marine-grade fasteners and copper or stainless top assemblies from Copperfield that outlast the original hardware without voiding the liner warranty.
- Partial chimney rebuilds above the roofline with Gelco liners in place - a scenario we hit regularly in Attleboro’s North Attleboro-adjacent neighborhoods where the brick was soft to begin with. The temptation is to yank the liner to rebuild, but Gelco’s compression-fit top assemblies often deform on extraction. We shore and rebuild around the liner when possible, or carefully extract and reinstall with a new compression band rather than gamble on reusing the old.
Our Gelco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, 24 hours a day. We book a Level-2 camera inspection with one of our background-checked, uniformed technicians.
- 2
Inspect and document. The tech runs a camera the full flue length, photographs every joint, crack, and creosote deposit, and delivers a plain-English verdict on the spot. You see what we see.
- 3
Quote and parts decision. We price the job upfront - no surprises on the bill. If Gelco OEM is available and makes sense, we use it. If a HeatShield cerfractory repair or DuraFlex alternative solves the problem more durably for your chimney’s geometry, we explain why and let you decide.
- 4
Repair and test. Most Gelco liner replacements and partial rebuilds finish in a single visit. We pressure-test or smoke-test every joint, verify proper draft, and clean the work area thoroughly.
- 5
Guarantee in writing. The 90-Day Done Right Promise covers the work - if it’s not right, we make it right, no paperwork, no arguing. The chimney doesn’t care what you paid for the house. It just needs to be right.

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 Russell Haines has put his hands on enough Gelco installations in this area to know which failures repeat and which are one-offs. Our Level-2 inspections end with photos you can see and a plain-English verdict - documented like an engineer, explained like a craftsman. If your Gelco liner needs help, we have the parts relationships to source correctly, and the multi-brand knowledge to specify a DuraFlex or HeatShield solution when that’s the better fit. The 90-Day Done Right Promise is in writing, no arguing. Most jobs complete in a single visit. We’ll be there when we say.
FAQs
No - provided the liner is not damaged during the rebuild and the original installation met Gelco’s clearance and fastening specs. We document pre-existing condition with photos before any masonry work begins, and we reinstall or support the liner to maintain those specs. If you’re concerned about warranty status, call (508) 545-9737 and we’ll review your installation paperwork during the free estimate.
Most full Gelco liner replacements in Attleboro homes take four to six hours and are completed in a single visit. Jobs stretch to a second day only when we’re also rebuilding the smoke chamber, replacing a damaged damper, or dealing with a particularly tall chimney on one of the old estates near the Highland Country Club. We’ll tell you before we start if your job is likely to run long.
A single minor crack in a Gelco rigid section can sometimes be addressed with a local HeatShield cerfractory seal if the surrounding masonry is sound and the crack doesn’t penetrate fully. Multiple cracks, flex liner crease failures, or any separation at a joint mean replacement - patching those is temporary at best and potentially hazardous. We show you the camera footage and explain which category you’re in before quoting either approach.
We carry common Gelco liner diameters, collars, and top assemblies on our trucks, and our Attleboro warehouse stocks the fast-moving sizes for this market. Unusual diameters or discontinued Gelco series typically arrive within two to three business days. If your heating season is active and the chimney is unsafe to use, we’ll discuss temporary measures or priority sourcing while we wait.
Poor Gelco installations we find in Attleboro often show three tells: gaps between liner sections visible on camera, inadequate top support that lets the liner sag, and missing or improper insulation in unlined masonry chimneys. Our inspection checks all three. If we find a factory defect or installation error that contributed to your current problem, we’ll note it in our report - it matters for how we fix it and what will last.
