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 Liner & Rebuild in Attleboro: What to Know First
As an independent DuraFlex service provider, Hearthstone Chimney Co. handles chimney liner and rebuild work on DuraFlex systems throughout Attleboro, typically completing most jobs in a single visit after a Level-2 camera inspection. We stock common DuraFlex diameters and termination components, so we’re not ordering parts while your fireplace sits cold. Our pricing is agreed upfront - the number on the estimate is the number on the invoice - and every liner job carries our 90-Day Done Right Promise in writing.
This page is for Attleboro homeowners who know they’ve got a DuraFlex liner in the flue, or suspect they need one installed, and want a crew that understands the difference between a DuraFlex Pro and a DuraFlex SW. If that’s your chimney, call (508) 545-9737. A live person answers, 24 hours a day.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex Pro (316Ti stainless) - crevice corrosion at the flex-to-rigid transition. In Attleboro’s older colonials, especially along the Woodcock Reservoir corridor, we see this where the Pro’s corrugated flex section meets the rigid tee or starter section. Condensation pools in the valleys during shoulder seasons when the chimney runs cool. We cut back to sound metal, install a properly sloped rigid transition, and verify with a pull-through camera before we button it up.
- DuraFlex SW (aluminized steel) - premature burn-through in wood-burning applications. The SW is rated for gas and pellet, but we’ve found it retrofit into wood-burning flues in several Attleboro capes from the 1980s build boom. The aluminized coating degrades where creosote accumulates at the smoke shelf. We replace with 316Ti or 321 alloy appropriate to the fuel type, not another SW, and document why for your records.
- DuraFlex Pro - seam separation at elongated offsets. When a chimney has significant offset (common in Attleboro’s fieldstone and brick construction), the Pro’s helical lock-seam can work open over thermal cycles. We identify the offset degree with a laser and either reroute with a manufactured elbow section or recommend a partial rebuild to straighten the flue path. No guesswork - we show you the laser readout.
- DuraFlex termination caps - wind-driven rain infiltration through OEM mesh screens. The standard DuraFlex cap mesh is fine for spark arresting, but Attleboro’s northeast exposure and winter wind off the reservoir can drive water through. We source marine-grade replacement mesh or upgrade to a Gelco or Famco cap with proper overhang and drip edge, matched to your liner diameter without adapter hacks.
- DuraFlex liner - inadequate support at the top plate in tall chimneys. On two-story Attleboro colonials with 30-foot-plus flue runs, we’ve found top plates that were never properly tensioned or have sagged after years of thermal expansion. The liner drops, creating a gap at the thimble or appliance connector. We reset with proper compression support, stainless draw bands, and a top plate with integral tensioning hardware - not a cobbled field repair.
Our DuraFlex Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, day or night. We’ll ask your fuel type, appliance age, and any symptoms - odd drafts, smoke rollout, water in the cleanout. We book a Level-2 inspection with camera.
- 2
Camera inspection and documentation. Russell Haines or one of our background-checked, uniformed technicians runs a high-res camera the full flue length. You see the footage in real time. We mark every defect, measure liner diameter and offset, and deliver a plain-English verdict with photos.
- 3
Parts decision: OEM DuraFlex or quality equivalent. If your DuraFlex Pro is salvageable, we source OEM replacement sections. If the full liner needs replacement, we may recommend Olympia Chimney or Copperfield 316Ti with equivalent or superior wall thickness - always disclosed, never substituted without your okay.
- 4
The repair or rebuild. Most liner replacements and partial rebuilds finish in one day. We protect your floors, work from the roof and hearth access as needed, and pressure-test gas-vent liners or do a smoke evacuation test on solid-fuel systems.
- 5
Final documentation and guarantee. You get photos of the completed work, a written condition report, and our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we make it right.
- 6
Cleanup and closeout. We haul away old liner sections and debris. The number on your estimate matches the invoice. We’ll note any maintenance timeline - typically an annual Level-1 inspection for solid fuel, every two years for gas.

These are real ranges for DuraFlex work we’ve completed in Attleboro and nearby Massachusetts markets. Your exact quote comes after camera inspection - estimates are free.
| Service | Typical Range | What Moves the Price |
|---|---|---|
| DuraFlex Pro liner section replacement (partial) | $1,200 - $2,400 | Height of chimney, offset complexity, access |
| Full DuraFlex liner replacement (single flue) | $2,800 - $5,500 | Diameter, length, insulation wrap, termination type |
| DuraFlex liner + partial chimney rebuild | $4,500 - $8,000 | Courses of brick to replace, crown condition, scaffolding needs |
| Full chimney rebuild with new liner system | $8,500 - $14,000 | Total height, decorative matching, permit requirements |
| DuraFlex termination cap / top plate replacement | $380 - $720 | Diameter, mesh grade, wind exposure rating |
Factors that increase cost: multi-flue chimneys requiring separate liners, historic district matching requirements in parts of downtown Attleboro, and concealed offset that wasn’t visible from the cleanout. Factors that don’t: we don’t charge extra for the camera inspection when bundled with repair work, and we don’t pad the bill with “trip charges” or “diagnostic fees” after the fact.

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’ve learned that chimney work is about what you can prove, not what you promise. Our Level-2 inspections end with photos you can see and a plain-English verdict - documented like an engineer, explained like a craftsman. The 90-Day Done Right Promise means if it’s not right, we come back. No paperwork to dig up, no arguing.
Our technicians carry DuraFlex, HeatShield, Gelco, and Olympia Chimney components on most trucks, so we’re not waiting on freight while your house gets cold. And because Russell Haines trained at Los Angeles Trade-Technical College before putting down roots in Massachusetts, he knows the difference between a liner that needs replacing and a liner that needs proper support - a distinction that saves Attleboro homeowners real money. The chimney doesn’t care what you paid for the house. It just needs to be right.
FAQs
DuraFlex’s warranty covers manufacturing defects on original product only; using an independent service provider like us does not void what remains of that coverage, but warranty replacement must use OEM DuraFlex parts. If your original warranty period has expired - most Pro liners carry 15 years, SW carries less - we typically recommend equivalent or upgraded 316Ti from Olympia Chimney or Copperfield with comparable or better specs, disclosed upfront. Call (508) 545-9737 and we’ll check your install date against warranty terms.
We stock common DuraFlex Pro diameters from 3 to 8 inches, flex lengths, and termination hardware at our Massachusetts warehouse. Uncommon sizes or SW series parts typically arrive in 3-5 business days. For urgent heating-season situations, we can often install a compatible temporary liner or expedite OEM freight - we’ll tell you honestly which makes sense for your timeline and budget. Call (508) 545-9737 to check current stock.
Localized damage - a failed top plate, minor seam separation, or isolated corrosion at the transition - usually warrants repair. We cut out the bad section and splice in new, pressure-tested. Widesde corrosion, multiple seam failures, or a liner that has dropped from its support indicate replacement. The camera inspection shows which category you’re in; we don’t recommend replacement unless we can show you why. Call (508) 545-9737 for a free camera inspection.
Most single-flue DuraFlex liner replacements in Attleboro homes are completed in one day, start to finish. Partial rebuilds adding masonry work typically run two days. Full chimney rebuilds with new liner systems take 3-5 days depending on weather and scaffold setup. We give you a specific day count in your written estimate - not a range that stretches.
A compromised liner allows exhaust gases, including carbon monoxide, to leak into wall cavities or living space. Creosote can also reach combustible framing through gaps. The risk is real and increases with use, though we won’t invent a hazard your chimney doesn’t have - the camera shows the actual condition. If the defect is minor and the chimney is unused, we’ll tell you that plainly and recommend a recheck timeline. Call (508) 545-9737 for an honest assessment.
