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 Norwood: What to Know First
DuraFlex chimney liner and rebuild work in Norwood typically runs between $1,800 and $6,500 depending on whether we’re replacing a section, relining the full flue, or rebuilding the chimney structure itself. Most DuraFlex jobs take one to two days once we’re on site, and we always give you the price before a single tool comes off the truck. If you’re reading this because your DuraFlex liner is showing signs of trouble, or a home inspector flagged it, call us at (508) 687-5884 and we’ll walk you through what you’re actually looking at.
This page is for Norwood homeowners who own or inherited a DuraFlex stainless steel liner and want straight answers about whether it needs repair, replacement, or a full rebuild. Wendell Pike and our crew have pulled more DuraFlex liners out of Norwood chimneys than we care to count, and we’ll tell you plainly if yours can be saved. If it doesn’t need doing, we’ll tell you that too.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex 316L liner seam separation at the corrugation peaks. The 316L alloy is solid, but the lock-seam construction on DuraFlex liners can pull apart at the corrugation crests when the liner shifts inside the flue, especially on tall two-story Norwood Capes where the flue runs 25 feet or more. We find this on camera inspection as a visible gap between the seam folds. The fix is usually a partial replacement of the affected section, not the whole liner, unless the separation runs more than a few feet.
- DuraFlex Pro (smooth-wall) liner pinhole corrosion from acidic condensate. The smooth-wall Pro series gives better draft, but oil-fired systems in older Norwood homes produce acidic condensate that eats through the thin spots. We see pinholes clustered near the bottom elbow where condensate pools. On a 2010s oil-to-gas conversion, this is the failure we find most often. The repair is a new Pro series section, and we advise an acid-resistant 316Ti alloy if the appliance is still oil.
- Improperly sized DuraFlex liner causing draft failure and backdrafting. We find more wrongly sized liners in Norwood than any other cause. A boiler rated for a 6-inch flue connected to a 5.5-inch DuraFlex liner will never draft right, no matter how much damper adjustment you throw at it. The symptoms are soot staining at the boiler draft hood and a lazy, smoky fire. The fix is a proper flue sizing calculation and a correctly sized replacement liner, not a band-aid.
- DuraFlex liner tearing at the rain cap collar from wind-driven movement. The Norwood Memorial Airport corridor gets real nor’easter wind, and a DuraFlex liner without a locking rain cap can rock back and forth enough to tear at the rivet line where the cap collar meets the liner. Homeowners call this in as a whistling sound on windy nights. The fix is a new locking cap and a short patch section, sometimes just the cap if we catch it early.
- Creosote glazing on third-degree buildup inside the DuraFlex liner. This is the one that people think needs a rebuild when it usually doesn’t. Third-degree creosote inside a DuraFlex liner looks like black glass and comes from burning unseasoned green wood or low-temperature fires. The liner isn’t ruined; it needs a professional mechanical removal, not just a brush. We use our rotary whip and camera to verify the entire flue wall is clean, then we check for any liner damage the glaze was hiding.
Our DuraFlex Chimney Liner & Rebuild Process
- 1
You call (508) 687-5884 and a live person answers. We don’t run a call center, and we don’t route you through a menu. We’ll ask about the symptoms, pull up the last cleaning record if we have one on file, and book a time that fits your schedule.
- 2
Wendell or one of his crew arrives in uniform, on time. We crawl the chimney top and bottom, drop a camera down the liner, and get you the footage and a plain-English verdict, every time, no exceptions. You see exactly what we see.
- 3
We give you a written price before any work starts. If the liner can be repaired, we’ll tell you that. If the liner is worn and replacement is the honest call, we’ll show you why on camera and price it for you. You decide, not us.
- 4
The repair or rebuild happens the same day in most cases. We carry DuraFlex 316L and Pro series liner sections on the truck, plus OEM connectors, caps, and framing plates. If we need a custom length, we’ll have it ready for a return visit within the week.
- 5
We test the draft and verify the new liner with a camera. You get a photo report of the completed job before the bill. No guessing.
- 6
The 90-Day Done Right Promise kicks in. If it’s not right, one call brings us back, in writing, on every single job. No fine print, no runaround.
What DuraFlex Chimney Liner & Rebuild Costs in Norwood
- DuraFlex liner inspection with camera: $149-$249, depending on chimney height and access. We waive this fee if you hire us for the repair within 30 days.
- Partial liner repair (short section, connector, or cap): $350-$900. Most common DuraFlex repair in Norwood.
- Full DuraFlex liner replacement (standard 316L, one-story flue): $1,800-$2,900.
- Full DuraFlex Pro smooth-wall liner (two-story or oil-fired): $2,400-$4,200.
- Full chimney rebuild (crown, brick, and liner, partial rebuild only above the roofline): $3,500-$6,500. Full rebuild from the foundation runs higher, usually $8,000-$14,000, depending on scaffolding and brickwork.
What moves the price is flue height, access, whether the existing clay tile liner needs to be removed first, and how much structural brickwork is actually failing. We don’t hide behind vague ranges. The number you hear on the phone is the number on the invoice. Call us at (508) 687-5884 for a free estimate.
Why Norwood Homeowners Call Top Hat Chimney for DuraFlex Work
We’ve been serving Norwood and the surrounding communities since 1999, and our roots go back to 1999. Wendell Pike puts his name and license number on every job we do, and he runs into you again at the hardware store on Saturday. We don’t hide behind a brand name or a rotating crew of strangers.
Here’s what that looks like in practice: A live person answers your call around the clock. The technician who shows up wears a uniform, is background-checked, and knows DuraFlex liners, not just a generic training video. If we find a HeatShield or Gelco liner up there instead, we work on those too. And when the job is done, the 90-Day Done Right Promise is stamped on your invoice. No national chain gives you that in writing.
FAQs
DuraFlex warrants their liners against manufacturer defects, typically for a limited lifetime period, but the warranty applies to the liner material, not the installation or damage from creosote, animals, or improper sizing. As an independent DuraFlex service provider, we’re not authorized to process warranty claims on DuraFlex’s behalf, but we can inspect your liner, document the failure with camera footage, and give you the evidence you need to pursue a claim if the defect qualifies. Call (508) 687-5884 and we’ll tell you honestly whether your issue is a material defect or an installation problem before you spend time on warranty paperwork.
A DuraFlex liner can often be repaired with a partial section replacement if the damage is localized, such as a seam separation, a tear at the cap collar, or pinholes near the bottom elbow. If the liner is corroded along its full length or was undersized from the start, replacement is the honest call. We’ll show you the camera footage before we recommend either route.
Most DuraFlex liner replacements in Norwood take one full day from setup to testing. If we’re removing old clay tile liner first, budget two days. We carry DuraFlex sections on the truck, so we aren’t waiting on a parts shipment unless it’s a custom length.
If the liner has a seam separation or pinholes, combustion gases and creosote are escaping into the chimney cavity, not the flue. That’s how chimney fires start, and it’s how carbon monoxide finds its way into the house. This is the one repair we tell Norwood homeowners not to sleep on. Call (508) 687-5884 and we’ll get you a camera-based quote this week.
We don’t sell liners for self-installation. Liner sizing, connection, and draft testing are skilled work, and a badly installed liner is worse than no liner at all because it gives you false confidence while the flue leaks. We’re happy to price the job for you, but we won’t hand you a box of liner and wish you luck.
