This page is for Allentown homeowners who already have a HeatShield liner, crown coating, or refractory product installed and need someone who knows how these specific systems fail in our climate. Russell Haines and our crew have worked HeatShield products across the Lehigh Valley for years, including plenty of older brick homes near West Park where freeze-thaw cycles hit hard. Call (610) 632-1394 to speak with a live person, any hour.

How HeatShield Products Fail - and How We Fix Them

• Cerfractory Foam liner resurfacing lifts or bubbles in HeatShield’s UL-Listed lining system. In Allentown’s wet shoulder seasons, moisture gets behind the foam layer where the original clay liner was cracked. We see this most in homes with marginal chimney caps. Our fix: strip the compromised section, re-apply with the proper Cerfractory bond coat, and verify with a camera pull before we close up.
• CrownSeal flexible coating cracks at the crown edge on HeatShield-treated crowns after 7-10 years. The product flexes well, but Allentown’s hard freezes in January and February test anything. When CrownSeal loses adhesion at the drip edge, water runs straight into the brick below. We cut back to sound substrate, re-coat with HeatShield CrownSeal or switch to Gelco’s crown treatment if the damage is too deep for a surface repair.
• Joint Repair (Smoke Chamber Parge) sags or delaminates in HeatShield smoke chamber applications. This happens when the original parge was applied over a soot-heavy surface or the chimney has seen heavy wood-pellet use. We grind to clean refractory, re-apply with proper surface prep, and run a mirror inspection to confirm full coverage. No guesswork.
• Flue Goo or similar refractory patch products shrink away from corbelled brick in pre-1950 Allentown chimneys. Many homes around 7th Street and the historic districts have corbelled shoulders that modern products weren’t designed to bridge. We pack with proper refractory mix or recommend a stainless liner from DuraFlex if the geometry is too irregular for a lasting patch.
• HeatShield liner coatings fail prematurely when paired with the wrong appliance. We’ve found HeatShield resurfacing rated for wood burning installed behind a gas insert running too cool, or vice versa. The chimney doesn’t care what it looks like from the street. We check what’s inside. We verify appliance category, flue size, and draft before touching the repair so the fix lasts.

Our HeatShield Chimney Repair Process

1. 1
   Call and schedule. A live person answers, 24 hours a day. We ask about your HeatShield product, symptoms, and appliance type so we arrive with the right materials.

   Level-2 camera inspection. We document everything with photos you can see. No hidden damage, no surprise recommendations. You get a plain-English verdict on what’s wrong and why.
3. 3
   Parts decision. If HeatShield OEM is available and makes sense, we use it. If lead times are long or the damage calls for a different approach, we explain the aftermarket or alternate-brand option - DuraFlex for liner replacement, Gelco for crown work - and you decide.
4. 4
   Repair with upfront pricing. The number on the estimate is the number on the invoice. No add-ons after we start.
5. 5

6. 6
   Cleanup and written guarantee. 90-Day Done Right Promise, in writing, no arguing. If it’s not right, we come back.
