This page is for Pottstown homeowners who already have a HeatShield liner, crown coating, or refractory product in their chimney and need it repaired correctly. Maybe you’ve noticed flaking material, a new draft issue, or water staining after last winter’s freeze cycles. Whatever the symptom, we’ll diagnose it honestly and fix it under our 90-Day Done Right Promise. Call (610) 819-4281 - a live person answers, 24 hours a day.

How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner resurfacing develops hairline cracking and surface spalling when Pottstown’s hard freeze-thaw cycles strike chimneys with marginal crown drainage. The foam layer separates from the substrate, creating voids that collect acidic condensate. We grind back to sound material, apply HeatShield-compatible bonding wash, and resurface to factory thickness - or switch to a DuraFlex stainless liner if the underlying clay is too far gone.
• HeatShield UL Listed CrownCoat chalks and thins prematurely on south-facing chimneys in Pottstown’s summer sun, especially where the original application missed the minimum 1/8-inch build. Water then migrates through pinholes and attacks the crown concrete beneath. We strip failing CrownCoat, repair the crown substrate with proper pitch and drip edge, then reapply CrownCoat to full specification or upgrade to a Gelco pre-formed crown seal if the concrete crown is too compromised.
• HeatShield Flue Gasket joints in factory-built chimney systems loosen after repeated thermal cycling, particularly in older Pottstown homes near Manatawny Street where the flue runs are longer and colder at startup. The gasket material compresses and loses its seal, leaking smoke and CO into wall cavities. We remove the affected gasket sections, clean the joint faces to bare metal, and reinstall with OEM-spec gasket or a compatible high-temp replacement rated to the same 1,700°F.
• HeatShield Smoke Chamber Parge delaminates when applied over oil-soaked or improperly prepared brick in chimneys that previously burned unseasoned wood - common in rural-exurban Pottstown properties. The parge layer sounds hollow when tapped and sheds sandy debris into the firebox. We mechanically scarify the chamber, apply a compatible oil-blocking primer where needed, and re-parge to NFPA 211 smoothness standards.
• HeatShield Refractory Panels in zero-clearance fireplaces crack from thermal shock when homeowners overfire during Pottstown’s January cold snaps. The panels are proprietary to each fireplace model, and aftermarket substitutes often fit poorly or carry lower temperature ratings. We source genuine HeatShield refractory where available, or fabricate custom-cut alternatives from Copperfield high-density refractory board when OEM panels are discontinued - always documented in your inspection report.

Why Pottstown Homeowners Call Hearthstone Chimney Co. for HeatShield Work

We’ve been sweeping and repairing chimneys in Montgomery County for over 42 years. Russell Haines, our owner, has spent the better part of two decades on Pottstown roofs - including plenty of older homes over near Manatawny Street where the chimneys are as stubborn as they are historic. He reads a flue quietly and carefully, and he doesn’t miss much.

We’re an independent HeatShield service provider - not affiliated with or authorized by the manufacturer - which means we evaluate your chimney on its merits, not on brand loyalty. If a DuraFlex liner or Gelco crown solution serves you better, we’ll say so. Our technicians carry professional-grade materials from HeatShield, DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield, so we’re not stuck waiting on a single supplier.

The 90-Day Done Right Promise covers every repair in writing. Calls are answered by a live person, 24/7. Most jobs finish in one visit. The chimney does not lie - and neither do we.
