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.

AfterHeatShield Chimney Cap & Crown in Attleboro: What to Know First
As an independent HeatShield service provider, Hearthstone Chimney Co. repairs and replaces HeatShield chimney caps and crowns throughout Attleboro, typically completing the work in a single visit with no-hassle upfront pricing agreed before we start. Most HeatShield cap and crown jobs run between $340 and $890 depending on whether we’re coating a hairline crown crack or replacing a multi-flue cap assembly that’s taken a hit from ice damming off the roofline.
This page is for Attleboro homeowners who already have a HeatShield product on their chimney and need to know whether it can be repaired, what it should cost, and who’s qualified to do the work without voiding whatever warranty remains. If that’s your situation, call (508) 545-9737. A live person answers, 24 hours a day.
How HeatShield Products Fail - and How We Fix Them
- Cerfractory Foam crown coatings (original formula) develop surface crazing after 8-12 winters in Attleboro’s freeze-thaw cycle. The foam expands and contracts at a slightly different rate than the concrete substrate beneath it, and once hairline cracks spider across the surface, water wicks straight through to the flue liner below. We strip the compromised foam, re-profile the crown with proper pitch, and reapply the current-generation Cerfractory coating - or switch to a poured concrete rebuild if the underlying crown has lost structural integrity.
- HeatShield ProForm stainless caps in the PF-200 series can warp at the mesh skirt where snow load sits heaviest. Attleboro’s nor’easters dump wet, heavy snow that settles and refreezes; the 24-gauge skirt on early PF-200 units fatigues at the crimp points. We replace with the updated PF-300 series (28-gauge, reinforced skirt) or, if the flue configuration allows, a Gelco multi-flue cap with a steeper snow-shed profile.
- Factory-welded seam caps (pre-2019 production) split at the corner joints after repeated thermal cycling. The MIG welds on these units work-harden every time the cap heats and cools; eventually the bead cracks and the cap starts funneling water onto the crown instead of off it. We cut off the failed cap, inspect the crown for hidden water damage, and install a current HeatShield unit with continuous-seam construction - or a custom-fabricated copper cap from Copperfield if the homeowner wants a 50-year solution.
- Cerfractory Flue Sealant used as a crown repair (improper application by non-certified sweeps) traps moisture and accelerates spalling. We’ve found this in three Attleboro homes near the Woodcock Reservoir, all done by the same defunct handyman service. The sealant is meant for flue joints, not horizontal surfaces. We remove the misapplied material, assess whether the crown is salvageable, and rebuild with the correct product for the job - crown coating for minor damage, full tear-off and pour for advanced deterioration.
- HeatShield’s earlier galvanized cap lines (discontinued GC series) rust through at the fastener holes first. The zinc coating wears thin where screws pass through, and Attleboro’s acidic rain - common downwind of Providence’s industrial corridor - attacks the exposed steel. By the time the homeowner notices drips in the firebox, the cap is perforated and the crown beneath is soaked. We replace with a stainless or copper cap, seal the fastener penetrations with high-temp silicone, and document the crown condition with camera photos the homeowner can see.
Our HeatShield Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, day or night. We book a window that works for you - no four-hour “maybe” windows.
- 2
Level-2 camera inspection on arrival. We photograph the cap, crown, and flue top from inside and out. You see the images on the tablet while we explain what we’re looking at. Russell Haines started this practice years ago after watching too many Attleboro homeowners get quoted work they couldn’t verify.
- 3
Parts decision: OEM HeatShield, quality aftermarket, or compatible upgrade. If your cap is under warranty, we source direct from HeatShield’s current catalog. If the warranty has expired, we’ll quote the OEM part alongside a Gelco or DuraFlex equivalent that may outlast it - your choice, no pressure either way.
- 4
The repair. For crown coating, we mask the flue, grind the surface to profile, and apply Cerfractory in lifts per manufacturer spec. For cap replacement, we remove the old unit without damaging the flue tile, seal all penetrations, and torque fasteners to spec - no impact drivers that strip threads.
- 5
Post-repair test and documentation. We run a smoke test to confirm draft behavior hasn’t changed, photograph the finished work, and leave you with a written report and the 90-Day Done Right Promise.
- 6
Cleanup and walkthrough. We haul away the old cap or debris. You approve the work before we leave. The number on the estimate is the number on the invoice.

Why Attleboro Homeowners Call Hearthstone Chimney Co. for HeatShield Work
The chimney doesn’t care what you paid for the house. It just needs to be right.
We’ve been in Attleboro long enough to know which neighborhoods have the pre-war colonials with oversized flues that never got proper caps, and which developments from the 1980s have HeatShield products installed by the original builder that are now due for attention. Our techs carry HeatShield parts on the truck when possible, but we’re not dependent on a single brand - if your job calls for DuraFlex liner compatibility or a Gelco cap that sheds snow better, we’ll tell you straight and source accordingly.
The 90-Day Done Right Promise means if it’s not right, we come back. In writing, no arguing. Most jobs finish in one visit. Background-checked, uniformed techs. A square deal: no surprises on the bill.
FAQs
No - as an independent HeatShield service provider, we follow manufacturer installation specs and use OEM parts when warranty coverage is still active, so your warranty remains intact. We document the work with photos and serial numbers in case you ever need to file a claim. Call (508) 545-9737 if you’d like us to verify your warranty status before booking.
HeatShield stocks replacement parts for most discontinued lines for at least 10 years after phase-out, and we maintain relationships with distributors who warehouse slow-moving inventory. For the rare cap that’s truly obsolete, we can fabricate a compatible solution from Copperfield or cross-reference to a Gelco unit that fits your flue configuration. We’ll know within minutes of measuring.
Coating works when the crown is structurally sound with surface cracking or minor spalling - typically under 1/4-inch depth and no exposed rebar. Full replacement is necessary when the crown has separated from the brick courses, shows through-cracks that leak into the smoke chamber, or has lost more than 30% of its mass to freeze-thaw damage. Our camera inspection shows you which category you’re in before any work is proposed.
HeatShield makes a solid stainless cap with good corrosion resistance, particularly the current PF-300 series. For some Attleboro homes - especially those with heavy snow load or proximity to salt air - we may recommend Gelco’s taller lid profile or a custom Copperfield fabrication. We don’t sell one brand because it’s profitable; we match the product to the conditions on your roof.
We book within a few business days for non-emergency cap and crown work, and sooner if water is actively entering the flue. We don’t promise same-day dispatch - a proper inspection takes time we won’t rush - but we do answer the phone live 24/7 and will tell you honestly where you sit on the schedule. Call (508) 545-9737 for a free estimate and we’ll find the first slot that works.
