How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner resurfacing - In Ashburn’s clay-heavy soil zone, minor foundation settling is common, especially in the older homes south of Route 7. That movement can stress a Cerfractory Foam liner at the smoke chamber transition, producing hairline cracks that look worse than they are. We camera-map the damage, then resurface only the affected section rather than relining the whole flue. Done right - and we stand behind it.
• HeatShield UL Listing compromised by aftermarket caps - Homeowners sometimes swap in a big-box cap after a storm, not realizing HeatShield’s UL listing requires compatible termination hardware. We see this on the TJ750 and TJ1000 series in Ashburn’s One Loudoun area. We source proper HeatShield-compatible caps or, when the homeowner prefers, transition to a Gelco or Famco cap that maintains draft performance without voiding underlying coverage.
• HeatShield CrownSeal cracking from thermal cycling - Ashburn sits at the freeze-thaw boundary of USDA Zone 7a, where winter mornings hit the teens and afternoon sun warms brick to 50 degrees. CrownSeal on exposed crowns develops alligatoring after 6-8 years here, faster than in milder climates. We grind back to sound substrate, reapply CrownSeal to factory spec, and add drip-edge detailing that HeatShield’s standard application sometimes skips.
• HeatShield Smoke Chamber Safe mixed with incompatible water repellents - A previous contractor in the Belmont Country Club area sprayed a silane-based waterproofer over Smoke Chamber Safe, causing surface whitening and reduced adhesion. We remove the incompatible layer with controlled abrasion, reapply Smoke Chamber Safe, and document the repair for the homeowner’s records. The flue doesn’t lie - and neither do we.
• HeatShield Flue Repair Resurfacing delamination near the damper frame - The FR Series resurfaces well until a rusted damper frame expands and pops the new surface from behind. We see this in Ashburn’s 1990s-era builds where original galvanized frames have corroded. We replace the frame with a stainless unit from Olympia Chimney, then resurface - fixing the root cause, not just the symptom.

Our HeatShield Chimney Repair Process

1. 1
   Call intake - A live person answers, notes your HeatShield product line if you know it, and schedules a Level-2 camera inspection. No voicemail, no callback queue.
2. 2
   Camera inspection and documentation - Our technician runs a full flue scan, photographs every defect, and explains what you’re seeing in plain English. You get the photos, not just our interpretation.
3. 3
   Parts decision - We specify OEM HeatShield materials when the repair must preserve factory warranty terms, or quality aftermarket from DuraFlex, Gelco, or Famco when the homeowner prefers and the application allows. No surprises on the bill either way.
4. 4
   Repair execution - Background-checked, uniformed technicians complete most HeatShield repairs in a single visit. Mortar work cures under controlled conditions; resurfacing products get their full cure time before we call it done.
5. 5
   Post-repair test and verification - We run a final camera pass, verify draft performance, and provide a written report with before-and-after images.
6. 6
   90-Day Done Right Promise activation - Your coverage is in writing before we leave. If it’s not right, we come back. No arguing, no paperwork chase.
