How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Flue Sealant shrinkage in the TJL series. The original TJL application can pull away from clay flue tiles after 8 to 12 years of Leesburg freeze-thaw cycling, especially in homes near the Potomac where humidity swings are sharper. We see this as a hairline gap at the tile joints that widens each winter. Our fix: mechanical removal of the compromised sealant, re-surfacing with compatible cerfractory material rated to the same 3,100°F spec, and a post-repair video scan to verify continuous coverage.
• HeatShield UL Listed Stainless Steel Liner seam separation in the 316Ti flexible lines. The corrugated sections can work loose at the seam collars in tall Leesburg colonials with exterior chimneys, where thermal expansion is greatest. This is not a patch job. We extract the damaged section, inspect the remaining run with a camera, and install a new HeatShield-compatible flexible segment or transition to a rigid DuraFlex or Gelco liner if the flue geometry allows a better long-term fit.
• HeatShield refractory crown coating delamination. The spray-applied crown repair product holds well on sound concrete but fails when applied over previously patched or salt-damaged crowns, which we find often in the older homes near Morven Park. We strip to sound substrate, rebuild the crown with proper slope and drip edge, then reapply only if the base is viable, or recommend a full cast-in-place crown instead.
• HeatShield ProLiner partial collapse in offset flues. The ProLiner’s flexible profile is excellent for straight runs but can crease at sharp offsets common in 1960s and 70s Leesburg ranchers. A creased liner traps creosote and restricts draft. We remove the ProLiner, evaluate whether an ovalization or a switch to a more pliable Gelco or DuraFlex flexible liner solves the geometry, and never reinstall a liner we know will fail again at the same bend.
• HeatShield Joint Repair system deterioration below the smoke shelf. The joint repair compound sees the most acid exposure and fastest temperature swings in this zone. In Leesburg, where many homeowners burn oak and hickory from local lots, the creosote acidity accelerates wear. We access through the cleanout, remove failed material, and reapply with enhanced ventilation at the smoke shelf, or recommend a full liner if the damage extends past two courses.

Our HeatShield Chimney Liner & Rebuild Process

1. 1
   Call and schedule. A live person answers, asks what you are burning and how often, and sets a window. Russell Haines has a saying: “Tell me what you are burning and how often, and I can tell you what your chimney looks like before I even climb up.”
2. 2
   Level-2 camera inspection. We run a full video scan, document every joint, seam, and surface with photos you can see, and give you a plain-English verdict on whether repair or replacement is the sound choice.
3. 3
   Parts decision. We source OEM HeatShield components when they are the right fit, but we also carry DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield products. We explain the trade-off, warranty implications, and price difference before you decide.
4. 4
   The repair. Our background-checked, uniformed technicians complete most HeatShield liner and rebuild jobs in a single visit. We protect your floors, work from the roof and hearth as needed, and clean up after.
5. 5
   Post-repair testing. We run another camera pass, perform a smoke or draft test depending on the work, and show you the results.
6. 6
   Documentation and guarantee. You receive photos, a written summary, and our 90-Day Done Right Promise in writing, no arguing. If it is not right, we come back.
