This page is for Attleboro homeowners who know they’ve got a HeatShield product in their chimney system and need someone who understands how these components age in our freeze-thaw climate. Russell Haines and our crew have worked on HeatShield systems throughout Attleboro, including the older colonials along the Woodcock Reservoir corridor where the original installations are now hitting twenty-plus years. If you’re seeing crumbling mortar, water stains, or draft problems, call (508) 545-9737. A live person answers 24 hours a day, and estimates are free.

How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam flaking in the flue. The Foam series is designed to resurface clay flue liners, but in Attleboro’s wet winters and freeze-thaw cycles, we’ve seen it delaminate when the original liner had hidden hairline cracks we couldn’t reach. We strip the failed foam, camera-inspect to find the crack source, and reapply only after proper surface prep - or recommend a DuraFlex stainless liner if the clay is too far gone.
• HeatShield Joint Repair pulling away at mortar seams. The Joint Repair system seals between flue tiles, but it needs a stable substrate. In Attleboro homes with the softer lime mortar common in pre-1950 construction, the mortar itself crumbles beneath the sealant. We don’t just re-coat; we repoint the joint with compatible mortar first, then apply Joint Repair over sound material.
• HeatShield CrownCoat cracking on the chimney crown. CrownCoat is a flexible sealant, but it can’t bridge active structural movement. We’ve found that south-facing crowns in Attleboro take UV damage faster, and homeowners sometimes get two seasons instead of the expected five. We remove the failed CrownCoat, assess whether the crown needs rebuild or just recoat, and reapply only when the concrete beneath is sound.
• HeatShield FireGuard spalling in fireboxes. FireGuard is meant to resurface firebrick, but it bonds poorly to glazed or soot-saturated brick. We’ve learned to expect this in Attleboro homes that burn green hardwood without regular sweeping. We media-blast the surface clean, verify absorption with a water-drop test, then apply FireGuard to brick that can actually hold it.
• HeatShield FlashSeal separating at the roofline. FlashSeal is a peel-and-stick membrane for chimney flashing, but it won’t adhere to oxidized aluminum or tar residue from previous repairs. In Attleboro’s older neighborhoods with multiple roof layers, we often find this exact situation. We strip to clean metal, use proper primer, and only then apply FlashSeal - or switch to custom copper flashing from Copperfield if the geometry is too complex for membrane.

Our HeatShield Chimney Repair Process

1. 1
   Call and schedule. A live person answers, day or night. We’ll ask what you’re seeing and when the HeatShield product was installed, if you know.
2. 2
   Level-2 camera inspection. Our technician arrives in uniform, runs a camera the full flue length, and photographs every defect. You see the images on screen; we explain what we’re looking at in plain English.
3. 3
   Parts decision. If OEM HeatShield material is the right fix, we use it. If a quality aftermarket alternative from Gelco or Olympia Chimney serves better for your specific failure, we’ll say so and explain why. As an independent HeatShield service provider, we have no obligation to push one brand over another.
4. 4
   Upfront pricing. We give you one number before any work starts. That’s the number on the invoice.
5. 5
   The repair. Most jobs finish in a single visit. Our technicians are background-checked and trained on HeatShield’s application requirements.
6. 6
   Testing and documentation. We verify the repair with another camera pass or smoke test, leave you with photos, and put the 90-Day Done Right Promise in writing. If it’s not right, we come back. No arguing, no paperwork chase.
