How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam Joint Repair - The foam injection system can separate at mortar joints in older Attleboro colonials where freeze-thaw cycling is aggressive, especially within a half-mile of the Woodcock Reservoir where humidity stays higher through winter. We see this as a thin crack line running the joint, sometimes with light spalling on the surface. Our fix: we remove the compromised foam section, re-prep the joint with HeatShield-compatible bonding agent, and re-inject with professional-grade cerfractory foam. We do not patch over failed foam; that traps moisture and guarantees a callback.
• HeatShield Flue Liner Resurfacing (CeCure Sleeve) - The sleeve system can delaminate if the original application missed a thin spot or if the chimney was fired too soon after installation. In Attleboro’s shoulder seasons, homeowners sometimes light the first fire of October on a liner that hasn’t fully cured from a September application. We diagnose this with our camera: a blistered or flaking surface that looks like alligator skin. Our fix: strip the failed section, re-abrade the substrate, and reapply with proper cure time - or sleeve with DuraFlex if the substrate is too compromised for reliable rebonding.
• HeatShield ProFormance Liner - This poured-in-place system can develop shrinkage cracks in tall, straight flues common in the 1920s bungalows around Attleboro’s city center. The crack pattern is vertical, hairline to 1/16 inch, and typically starts three to five feet down from the crown where thermal stress concentrates. Our fix: we map the crack extent with camera and light abrasion, then determine whether a local HeatShield re-pour will suffice or if the flue needs a full DuraFlex liner insert. We show you the footage and explain both paths before quoting.
• HeatShield CrownSeal Application - CrownSeal is a crown repair product, not a liner, but we include it because Attleboro homeowners often confuse the two. It fails when applied over a crown that still holds internal moisture, which is common after wet New England springs. The symptom is surface bubbling or peeling within 18 months. Our fix: we grind the crown to sound concrete, let it breathe for a full day when weather permits, then reapply CrownSeal or recommend a Gelco pre-formed crown if the structural damage is too deep for coating.
• HeatSmoke Chamber Restoration (PouRite System) - The smoke chamber is the upside-down funnel above the firebox, and HeatShield’s PouRite system fills corbels and smooths the chamber. In Attleboro’s older homes with shallow fireboxes, we’ve seen PouRite slump if the formwork was removed too early or if the mix was over-watered. The result is a rough, uneven surface that traps creosote. Our fix: we re-form and re-pour to proper thickness, or switch to hand-troweled HeatShield smoke chamber mix if access is too tight for the PouRite form system. Either way, we verify with camera before we leave.

Our HeatShield Chimney Cleaning & Sweep Process

1. 1
   Call and schedule - A live person answers, confirms your HeatShield product if you know it, and books a window. We ask about the last sweep date, any changes in draft or odor, and whether you’ve noticed exterior staining.
2. 2
   Level 1 or Level 2 inspection - For annual sweeps, we start with a Level 1 visual inspection and rotary sweep. If we see HeatShield product, or if you report performance issues, we upgrade to Level 2: full camera inspection from firebox to crown, with photos you can see on the tablet as we work.
3. 3
   Diagnosis and parts decision - We identify your HeatShield system by visual markers: foam injection ports, sleeve seams, pour marks, or application texture. For repairs, we source OEM HeatShield materials when the job demands exact compatibility, or specify quality aftermarket equivalents from our Copperfield and Famco supply chain when they meet or exceed spec and save you money without voiding any remaining warranty.
4. 4
   The sweep and any repair - We sweep first, repair second, so debris doesn’t contaminate fresh HeatShield material. Technicians work in uniform, lay protection, and complete most jobs in a single visit. No-hassle upfront pricing means the estimate number is the invoice number.
5. 5
   Post-job testing and documentation - We run a final camera pass, verify draft with a manometer, and provide a written report with photos, our plain-English verdict, and any recommendations ranked by urgency. Work that can safely wait is noted as such.
6. 6
   The 90-Day Done Right Promise - In writing, no arguing. If it’s not right, we come back. The chimney doesn’t care what you paid for the house. It just needs to be right.

What moves the price: flue height, roof access difficulty, extent of HeatShield failure, and whether we can repair in place or need to remove and reapply.
