How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner coatings degrade from thermal cycling in Attleboro’s freeze-thaw winters. The foam layer expands and contracts through our hard Massachusetts Januarys, especially in two-story colonials around the Woodcock Reservoir corridor where chimneys run cold between burns. We strip the compromised foam, inspect the underlying clay flue for spalling, and reapply only if the substrate is sound. Otherwise we sleeve with a stainless steel liner.
• HeatShield UL-Listed stainless liners in the HS-316Ti series can develop seam separation at the flex points. This happens where the liner navigates an offset in older Attleboro chimneys, common in 1920s construction. We cut back to solid metal, weld or mechanically lock the joint, and sleeve with DuraFlex if the damage extends beyond a single accessible point.
• HeatShield poured refractory liners crack at the smoke shelf in fireplaces converted to inserts. The poured mass cannot flex where the original firebox meets the flue throat. We remove the failed pour, camera-map the void, and install a Gelco or Olympia Chimney rigid liner sized to the appliance’s BTU output.
• HeatShield joint systems in the ProLiner line loosen at the collar connections after 8-12 years of wood-pellet service. Pellet exhaust is acidic and cooler than cordwood, so condensation collects at the joints. We replace the collars with OEM-spec hardware or transition to a continuous flexible liner if multiple joints are compromised.
• HeatShield crown-mounted termination caps corrode from road salt aerosol on Attleboro’s Route 1 corridor. The cap fails, water enters, and the liner rusts from the top down. We replace with a Copperfield or Famco stainless cap with proper overhang and screen, then inspect the liner interior for vertical rust streaks that indicate how far water traveled.

Our HeatShield Chimney Liner & Rebuild Process

1. 1
   Call and schedule. A live person answers, checks our calendar, and books a Level-2 camera inspection. We confirm our $89 Seasonal Tune-Up applies if we’re already doing sweep work.
2. 2
   Inspection with documentation. Our technician runs a camera the full flue length, records video, and photographs every defect. You see the images on a tablet before we leave the attic or basement.
3. 3
   Plain-English verdict and parts decision. We explain whether your HeatShield component can be repaired with OEM parts, if a quality aftermarket equivalent from DuraFlex or Gelco makes better sense, or if the warranty is already void and full replacement is the honest call.
4. 4
   Upfront pricing and scheduling. You get one number. The number on the estimate is the number on the invoice. No surprises.
5. 5
   Repair and testing. We complete most HeatShield liner and rebuild jobs in a single visit. After installation we run a smoke test or video verification to confirm draft and seal.
6. 6
   Cleanup, photos, and guarantee. We leave the work area as we found it. You receive after photos and a written 90-Day Done Right Promise. If it’s not right, we come back. No paperwork to find, no argument.

What HeatShield Chimney Liner & Rebuild Costs in Attleboro

What moves the price: flue height (Attleboro’s two-story colonials add 15-20 feet over a ranch), number of offsets, whether the crown and chase need rebuilding too, and if we discover hidden fire damage the camera could not reach. We show you everything before you decide. Call (508) 545-9737 for a free estimate.

We’ve been answering the phone with a live person for over 42 years, and we plan to be here in thirty more. That changes how you treat a customer.

When HeatShield parts are back-ordered, we have relationships with DuraFlex, Gelco, and Olympia Chimney to keep your job moving. The chimney doesn’t care what you paid for the house. It just needs to be right.
