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 Attleboro: What to Know First
As an independent DuraFlex service provider, we install, repair, and replace DuraFlex chimney caps and crowns throughout Attleboro and nearby Massachusetts towns. Most DuraFlex cap and crown jobs are completed in a single visit, with upfront pricing agreed before we start - the number on the estimate is the number on the invoice. We’re not the cheapest outfit in Bristol County, and we don’t try to be; we charge enough to do the job with proper parts and stand behind it for 90 days in writing.
This page is for Attleboro homeowners who already have a DuraFlex chimney component - whether it’s a factory-built cap that blew off in a nor’easter, a cracked crown letting water into the flue, or a multi-flue setup that needs matching coverage. If you’re unsure what you’ve got, we’ll sort that out when we arrive. 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 factory-built caps lose their mesh screening in Attleboro’s freeze-thaw cycles. The expanded stainless mesh on the SW series fatigues at the crimp points after five to seven winters, opening gaps that let squirrels and starlings nest in the flue. We replace with OEM-spec DuraFlex mesh or, when the frame is still sound, fit a Gelco stainless screen overlay that outlasts the original.
- DuraFlex Pro multi-flue caps develop corner-seam separation because the Pro series uses a single-piece stamped lid that flexes under heavy snow load. The 304 stainless holds, but the spot-welded corners crack where the lid meets the skirt. We’ve repaired dozens of these in Attleboro’s older neighborhoods - the colonials near Woodcock Reservoir seem to catch the worst drift. We either re-weld with TIG and seal, or source a replacement Pro cap with reinforced corner gussets.
- DuraFlex crown coating (the factory gray elastomeric) chalks and cracks on south-facing chimneys in Attleboro inside of four years. UV exposure on roofs without tree cover degrades the factory coating faster than DuraFlex’s published specs suggest. We strip to bare concrete, then apply HeatShield CrownCoat in two passes - it bonds better and carries a longer field track record in New England sun.
- DuraFlex DW double-wall caps suffer creosote bridging when the inner wall clearance is compromised by improper cap height. The DW series needs exactly 3/4 inch of exposed inner wall above the outer jacket for proper draft; caps installed too low create a cold spot where creosote plates across the flue opening. We measure with a depth gauge, then install a spacer or replace with the correct DW cap height.
- DuraFlex chase covers (the galvanized line, not stainless) rust through at the drip edge in Attleboro homes with asphalt shingle runoff. The galvanized coating lasts eight to ten years in this climate, then the pan edge pinholes and stains the chimney face. We replace with 304 stainless or copper from Copperfield - never another galvanized pan - and extend the drip edge to clear the shingles.
Our DuraFlex Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, asks what you’re seeing, and books a window. We don’t give blind quotes over the phone - we need eyes on it.
- 2
Level-2 camera inspection. Our tech arrives uniformed and background-checked, sets up the camera, and documents the cap, crown, and flue condition. You see the photos on the spot; we explain what we’re looking at in plain English.
- 3
Parts decision. If it’s a stock DuraFlex cap, we carry common sizes on the truck. If it’s discontinued or custom, we source OEM or quality aftermarket - Gelco for mesh, HeatShield for coating, Olympia Chimney for specialty flue adapters. We tell you which we’re using and why, with pricing before any work starts.
- 4
The repair or replacement. Most DuraFlex cap and crown jobs finish in two to four hours. We use proper fasteners (never sheet-metal screws into brittle crown concrete), seal with high-temp silicone rated for the application, and verify clearances on multi-flue setups.
- 5
Post-job test and documentation. We run a draft test, check for leaks with a water hose (weather permitting), and email you the photos and a written summary. The 90-Day Done Right Promise goes into effect immediately - in writing, no arguing.
- 6
Cleanup and walkthrough. We haul away the old cap or crown debris, sweep the roof and ground, and review the work with you before collecting payment. No surprises on the bill.
What DuraFlex Chimney Cap & Crown Costs in Attleboro
| Service | Typical Range |
|---|---|
| DuraFlex cap replacement (standard single-flue, stainless) | $280 - $450 |
| DuraFlex Pro multi-flue cap repair (corner weld + seal) | $340 - $520 |
| DuraFlex Pro multi-flue cap replacement | $480 - $750 |

What moves the price: accessibility (steep roof, multiple stories), whether the flue needs relining work discovered during inspection, and custom sizing for non-standard DuraFlex installations. We don’t upsell - if the crown can be coated instead of rebuilt, we’ll tell you, and we’ll show you the photo that proves it.

Our techs know DuraFlex products specifically, not just “chimney stuff.” They also carry HeatShield and Gelco inventory, so when a DuraFlex part is backordered or discontinued, we have a proven alternative ready - not a substitute that voids your warranty or fails in two seasons.

Russell Haines, our owner, trained at Los Angeles Trade-Technical College before coming east and putting down roots in Massachusetts. He’s spent years working Attleboro’s older housing stock, including the colonials along the Woodcock Reservoir corridor that never seem to have had a proper sweep in a decade. The chimney doesn’t care what you paid for the house. It just needs to be right.
FAQs
No - provided the repair uses OEM-spec or equivalent parts and follows DuraFlex installation clearances. As an independent DuraFlex service provider, we document every part number and measurement so your warranty stays intact. If your cap is still under DuraFlex’s original warranty, we’ll note that on your invoice and flag any claim-worthy defect we find. Call (508) 545-9737 and we’ll check your install date against the warranty terms.
Most standard single-flue replacements take two to three hours from ladder set to cleanup. Multi-flue Pro caps or jobs requiring roof-access equipment add an hour. We complete most DuraFlex cap and crown jobs in a single visit because we stock common sizes and fastener kits. If your cap is custom-sized, we measure, order, and return within five to seven business days - we’ll tell you upfront if that’s the case.
Yes - we cross-reference the DuraFlex part number against Gelco and Olympia Chimney equivalents that fit the same flue specification. In some cases, a quality aftermarket cap outperforms the original DuraFlex design, especially for the galvanized chase covers that DuraFlex no longer produces. We show you both options with pricing and let you decide. No pressure either way.
We determine that with a camera inspection and a simple probe test. Hairline surface cracks without spalling or exposed rebar usually qualify for HeatShield CrownCoat - a two-pass application that seals and flexes with thermal expansion. If the crown is crumbling, pitched wrong for drainage, or missing chunks at the flue edge, it needs partial or full rebuild. We’ll show you the photo and explain which category you’re in before quoting. Call (508) 545-9737 for a free inspection.
We offer a permanent 5% discount for seniors and veterans, applied to any DuraFlex cap or crown service. We also run a $50-off promotion on repairs over $250, and our $89 Seasonal Tune-Up includes a cap and crown condition check. If you have a written estimate from another company, we’ll provide a free second opinion - Russell Haines reviews it personally. No gimmicks, no expiration dates that pressure you into a hasty decision.
