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.
DuraFlex Chimney Cap & Crown in Taunton: What to Know First
We provide independent DuraFlex chimney cap and crown service in Taunton, with most inspections and repairs completed in a single visit. A standard DuraFlex cap replacement or crown coating runs between $280 and $650 depending on flue count and access, and we do not start work until you have seen the photos and approved the price in writing. This page is for Taunton homeowners who already have DuraFlex components on their chimney and need someone who knows the difference between a DuraFlex 316Ti flex liner termination and a standard galvanized cap that does not belong there. If you’re seeing rust streaks, hearing flapping in a south wind off the Taunton River, or just want to know what you’re looking at up there, call (774) 310-4281. A live person answers.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex 316Ti flex liner termination collars loosen in Taunton’s freeze-thaw cycles. The 316Ti series uses a clamp-band termination that expands and contracts differently than the masonry crown it sits on. After three or four winters in Taunton, that gap opens enough to let water run behind the collar and pool on the smoke shelf. We pull the termination, inspect the crown surface underneath, and reinstall with a proper crown-seal interface - not just more caulk that will fail again by February.
- DuraFlex DW (double-wall) factory-built cap seams separate at the lid joint. The DW series cap is a stamped lid over a welded skirt, and the spot-welds at the corner radii fatigue from thermal cycling. We see this most on Taunton’s 1980s raised-ranch chimneys where the flue runs hot and cools fast. Our fix: source a replacement cap with continuous-seam construction, or when the flue configuration allows, step up to a Gelco multi-flue cap with a deeper overhang that sheds water past the crown edge.
- DuraFlex Pro cap mesh corrodes from the inside out near salt air. Taunton is not coastal, but the humidity off Mount Hope Bay and the salt on winter road spray gets into the mesh from below during downdrafts. The Pro series uses 5/8-inch mesh that looks fine from the ground while the wire is half-gone above the flue. We replace with 304 stainless mesh on the same cap body when the frame is sound, or spec a full replacement when the frame has started to pit.
- DuraFlex crown-mounted terminations without proper cricket backing collect ice. On Taunton’s shallower-pitched roofs, especially the capes and bungalows near Whittenton Pond, a DuraFlex termination sitting on a flat crown with no cricket behind it traps meltwater that refreezes. The ice lifts the cap skirt and tears the seal. We fabricate a soldered copper or aluminum cricket as part of the crown repair, sloped to shed water left or right of the flue - not just patch the crown and hope.
- DuraFlex 304-to-316 mixed-system caps galvanically corrode at the connection. Some Taunton installers saved money by pairing a 304 stainless DuraFlex cap with a 316Ti liner, or vice versa. The dissimilar metals set up a galvanic cell that accelerates corrosion at the clamp point. We spot this during camera inspection by the rust pattern at the flue top. The fix is matching the alloy through the stack, not just replacing the failed part and waiting for the next failure.
Our DuraFlex Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, checks our calendar, and books a window. We ask whether you know your DuraFlex series or liner diameter - helpful, not required.
- 2
Level-2 camera inspection on arrival. Our technician runs a camera up the flue and photographs the crown, cap, and termination from the top. You see the images on a tablet before we quote anything.
- 3
Parts decision with you. We stock common DuraFlex caps and crown repair materials. If your job needs an OEM DuraFlex part we do not carry, we order it and explain the lead time versus a quality aftermarket equivalent that fits. You choose.
- 4
Repair with documentation. Cap replacement, crown coating with HeatShield CrownSeal, or full crown rebuild - done with the right alloy match, proper slope, and cricket where the roof demands it. Photos at every stage.
- 5
Post-repair camera verification. We run the camera again to confirm clear flue, proper draft, and no debris from the work. The report goes to you by email.
- 6
Written guarantee and cleanup. The 90-Day Done Right Promise, in writing, no arguing. Technician vacuums the work area. You pay the price we quoted.

Why Taunton Homeowners Call Hearthstone Chimney Co. for DuraFlex Work
We are not a price-cutting chain, and we are not a one-truck operator who might answer the phone next year. Hearthstone Chimney Co. has served Taunton and nearby communities for over 42 years.

Russell Haines has run sweeps and inspections across Taunton for the better part of two decades, including the older colonials near Taunton Green where chimneys vary as much as the families living in them. He reads a flue the way other people read a room - quietly, thoroughly, and without missing much. Our technicians are background-checked, uniformed, and trained on DuraFlex, HeatShield, and Gelco systems. Most jobs finish in one visit. If it’s worth burning wood in, it’s worth knowing the chimney is clear.
FAQs
DuraFlex warranties cover manufacturing defects on the liner and components, not installation errors. As an independent DuraFlex service provider, we use DuraFlex-specified parts and follow manufacturer clearances, so your warranty remains valid for defects. Installation warranty comes from us: the 90-Day Done Right Promise, in writing. Call (774) 310-4281 if you have questions about your specific DuraFlex warranty terms.
Most single-flue DuraFlex cap replacements take 90 minutes to two hours from ladder set to final photo. Multi-flue caps or jobs requiring crown repair first run three to four hours. We complete most DuraFlex chimney cap and crown jobs in Taunton in a single visit because we stock the common diameters and alloys. Call (774) 310-4281 to check current availability for your flue size.
We can coat a crown with HeatShield CrownSeal if the structural concrete is sound and cracks are less than a quarter-inch wide. If the crown has spalled past the rebar, slopes inward toward the flue, or is cracked through to the flue wall, we recommend full rebuild. We show you the camera image and explain which category you’re in before quoting either option. Estimates are free - call (774) 310-4281.
We stock DuraFlex 316Ti and 304 termination caps in common diameters, plus HeatShield crown repair materials and Gelco multi-flue caps that mate to DuraFlex systems. Uncommon sizes or factory-ordered colors take three to five business days. We tell you before booking whether your part is on the truck or needs ordering. Call (774) 310-4281 with your flue diameter and we’ll know immediately.
Rust streaks on the chimney face, water in the firebox after rain, or a cap that sits crooked are failure signs, not dirt. A dirty cap still sheds water and keeps animals out. If you’re unsure, book a Level-2 inspection - we run the camera, photograph the cap and crown, and tell you plainly whether you need work or just a sweep. The inspection is free with repair, or $149 if you decline. Call (774) 310-4281 to schedule.
