How HeatShield Products Fail - and How We Fix Them

• Cerfractory Foam liner sealant degradation in the UL-1777 listed systems. The foam-and-jacket combination that HeatShield uses to resurface clay flue tiles can delaminate after 8-12 years in Falls Church’s freeze-thaw cycle, especially where the chimney crown has hairline cracks letting water sit against the foam. We strip the failed foam, inspect the underlying tile with a camera, and either reapply with proper cure-time protocols or recommend a stainless steel liner if the substrate is too far gone.
• HeatShield Thermix 2000 joint separation in offset flues. The Thermix 2000 poured liner system sets rigid, and in older Falls Church colonials with angled offsets near the smoke chamber, thermal expansion can crack the pour at the turn. We find this with a Level-2 camera inspection - the crack shows as a hairline at 10 o’clock on the video - and repair with a partial Thermix re-pour or transition to a flexible DuraFlex liner through the offset.
• Stainless steel jacket corrosion in the Hybrid system when paired with unlined exterior chimneys. The 316Ti stainless jacket on HeatShield’s Hybrid liners resists acid well, but in Falls Church’s humid summers with condensing gas appliances, exterior chimneys that stay cold can cause jacket pitting from the outside in. We catch this early with camera inspection and replace with a fully-insulated Gelco or Olympia Chimney liner rated for exterior exposure.
• Smoke chamber parging failure in HeatShield-restored systems. When the original HeatShield job included smoke chamber parging but skipped the corbelled ledge detail, creosote and moisture collect at the ledge and undermine the parge from below. We remove the loose material, re-parge with proper ledge coverage, and document the repair with photos you can see.
• Improperly sized original liner causing draft failure. Some Falls Church homes got HeatShield systems sized by a previous owner for a different appliance - a wood insert removed and replaced with a higher-BTU gas unit, for instance. The liner diameter no longer matches the appliance, and the fix is not another HeatShield product but a correctly-sized replacement from our DuraFlex or Gelco inventory, with a new collar and proper termination.

Our HeatShield Chimney Liner & Rebuild Process

1. 1
   Call and schedule. A live person answers, asks what appliance type you have and what symptoms you’re seeing, and books a Level-2 inspection. We do not diagnose over the phone.
2. 2
   Camera inspection and documentation. Our technician runs a camera the full flue length, photographs every defect, and explains the footage in plain English. You see what we see. Russell Haines reviews every HeatShield report personally - he spent two decades running crews across Northern Virginia and knows the older colonials near the West Falls Church Metro corridor where HeatShield systems were popular in the 2000s.
3. 3
   Parts decision: OEM HeatShield, quality aftermarket, or cross-brand replacement. If the original HeatShield component is available and appropriate, we use it. If the system has been discontinued or a different brand solves the problem better - a flexible DuraFlex liner for a difficult offset, a Gelco insulated liner for an exterior chase - we explain why and let you decide. No brand loyalty that costs you money.
4. 4
   Repair or rebuild with upfront pricing. The estimate is the invoice. We agree on the number before any work starts.
5. 5
   Post-repair testing and documentation. We run another camera pass, perform a draft test where applicable, and leave you with photos, a written report, and the 90-Day Done Right Promise in writing.
6. 6
   Cleanup and follow-up. Background-checked, uniformed technicians protect your floors and furniture. If anything is not right, we come back. No paperwork, no arguing.
