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.

AfterDuraFlex Chimney Repair in Attleboro: What to Know First
We provide independent DuraFlex chimney repair in Attleboro, with most jobs completed in a single visit and upfront pricing agreed before we start. Typical turnaround from call to completion is three to five business days during peak season, faster when the weather cooperates. We’re not the cheapest outfit in Bristol County, and we don’t try to be - we quote the number you’ll pay, use the parts the job actually requires, and stand behind the work with our 90-Day Done Right Promise in writing.
This page is for Attleboro homeowners who’ve been told their DuraFlex liner, cap, or component needs attention, or who’ve noticed draft problems, water stains, or masonry damage and want a second opinion from someone who knows the product line. If that sounds like your situation, call us at (508) 545-9737. A live person answers, 24 hours a day.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW 304/316 stainless liners: The flex sections at the first offset above the smoke shelf take the worst thermal cycling in Attleboro’s freeze-thaw climate. We’ve found premature fatigue cracks in the corrugations where the liner bends through a 30-degree or greater offset, especially in homes built before 1960 with unlined terra cotta thimbles. We cut back to sound material, install a custom-fabricated rigid transition, and sleeve with new DuraFlex SW matched to the existing gauge - not a universal kit that changes the draft characteristics.
- DuraFlex Pro 316Ti chimney caps: The mesh spark arrestor on the Pro series can clog with creosote flakes faster than galvanized alternatives, particularly when homeowners burn unseasoned oak or maple from local cordwood suppliers. The cap itself warps from the trapped heat. We clean the flue first, then replace with either an OEM DuraFlex Pro cap or a Gelco equivalent with wider mesh spacing if the burn habits aren’t changing - and we tell you which we’re using and why.
- DuraFlex relining mortar joints (HeatShield-compatible installations): When DuraFlex liners were paired with HeatShield Cerfractory Foam resurfacing in the 2000s, the interface point between rigid foam and flexible liner sometimes separated as the foam cured and shrank. In Attleboro’s older capes and ranches near the Ten Mile River basin, we’ve found gaps of a quarter-inch or more that vent flue gases into the chase. We remove the compromised section, re-pour with HeatShield to factory spec, and reinstall with an expansion collar - never just caulk over it.
- DuraFlex AL 29-4C aluminum gas liner installations: The AL series was marketed heavily for Category I gas appliances in the 2010s, but Attleboro’s high-efficiency boiler retrofits often exceed the liner’s temperature rating when the installer didn’t downsize the appliance properly. We see sagging and delamination where the aluminum softened above 1,000°F. We replace with DuraFlex SW 316 or Olympia Chimney’s equivalent, sized to the appliance’s actual BTU output per NFPA 211 - not the original installer’s napkin math.
- DuraFlex chase cover integration: Factory chase covers with stamped DuraFlex knockouts often leak at the seal within eight to ten years in New England’s coastal snow load zones. Water runs down the flue, saturates the insulation wrap, and accelerates exterior spalling on brick chimneys. We fabricate a custom Copperfield or Famco chase cover with a welded collar and storm collar, sealed with high-temp silicone - not the peel-and-stick flashing tape that fails in February.
Our DuraFlex Chimney Repair Process
- 1
Call and schedule: A live person answers, asks what you’re seeing, and books a Level-2 inspection. We confirm our $89 Seasonal Tune-Up applies if we’re already doing repair work.
- 2
Level-2 camera inspection: Our technician runs a chimney camera the full length of the flue, documents every joint, offset, and defect with photos you can see on the spot, and delivers a plain-English verdict - no jargon, no scare tactics.
- 3
Parts decision: We check DuraFlex OEM availability against quality aftermarket equivalents from Olympia Chimney or Famco. If the OEM part is back-ordered (common on discontinued AL series components), we explain the aftermarket option, show you the warranty difference, and let you choose - never substitute without consent.
- 4
Upfront pricing and authorization: You get one number. That’s the number on the invoice. Our $50 Off Any Repair Over $250 applies automatically; your 5% Senior or Veteran discount applies if eligible.
- 5
The repair and post-work test: We complete most DuraFlex repairs in a single visit. Afterward, we run a smoke test or draft gauge check to verify proper draw, clean the work area, and walk you through the photos of what changed.
- 6
Written guarantee: You receive our 90-Day Done Right Promise documentation before we leave - in writing, no arguing. If it’s not right, we come back.

Why Attleboro Homeowners Call Hearthstone Chimney Co. for DuraFlex Work
We’ve been answering the phone with a live person for over 42 years, and we plan to be in Attleboro thirty years from now. That changes how you treat a customer.
Our background-checked, uniformed technicians carry DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield parts on most trucks - not because we’re fancy, but because the right part for your chimney might be from two different manufacturers. Russell Haines, our owner, trained at Los Angeles Trade-Technical College before following work east and settling in this corner of Massachusetts. He’s spent years in the older colonials along the Woodcock Reservoir corridor, where the chimneys haven’t seen a proper sweep in a decade and the DuraFlex installs were often done by roofers who didn’t read the manual.
We document everything with photos, explain what you’re seeing in plain English, and put our 90-Day Done Right Promise in writing before we leave. No paperwork to file, no arguing if something’s off. The chimney doesn’t care what you paid for the house. It just needs to be right.
FAQs
No, provided the repair uses DuraFlex-compatible parts and follows NFPA 211 installation standards. As an independent DuraFlex service provider, we’re not affiliated with the manufacturer, but we source OEM or equivalent-grade components and install to code - which preserves any remaining warranty coverage. If your liner is still under warranty, we’ll note that in our report so you have documentation. Call (508) 545-9737 and we’ll check your install date against the warranty period.
Most single-component repairs - caps, chase covers, section replacements - are completed in two to four hours during one visit. Full liner replacements usually require a full day, with the flue offline until the smoke test passes. We don’t promise same-day dispatch, but we do promise we’ll be there when we say. Call to check current scheduling in Attleboro.
We stock common DuraFlex SW and Pro series components, and our distributors in Massachusetts typically deliver specialty items within three to five business days. Discontinued AL series parts sometimes require fabrication or aftermarket substitution, which we discuss with you before ordering. We don’t leave you with an unsafe flue in the meantime - if the chimney can’t be used, we’ll tell you plainly and suggest interim measures.
The camera inspection tells the story. Isolated cracks, localized corrosion, or a failed cap usually justify repair. Multiple fracture points, delamination over more than a third of the run, or gauge thinning below manufacturer minimum means replacement is the honest recommendation - and we’ll show you the photo evidence so you can see why. No camera evidence, no upsell. Call (508) 545-9737 for a free inspection and a straight answer.
Yes. We regularly service HeatShield resurfacing systems, Gelco caps and components, and Olympia Chimney liners. Many Attleboro homes have mixed systems from multiple decades of repairs, and our technicians are trained to identify what’s in your flue before quoting work. We don’t guess, and we don’t learn on your chimney.
