How HeatShield Products Fail - and How We Fix Them

• Cerfractory Foam liner resurfacing breakdown. The Foam system is marketed as a repair coating for clay flue tiles, but in White Plains we’ve seen it delaminate after repeated freeze-thaw cycles when water gets behind the coating through crown cracks. We remove the failed foam mechanically, inspect the underlying clay with a camera, and either reline with a stainless HeatShield UL-listed liner or rebuild the flue section if the tile is too far gone. The freeze-thaw reality here means we won’t resurface over suspect substrate.
• ProForm liner joint separation in tall flues. The ProForm sleeve system can pull apart at the seam in runs over 25 feet, especially where the chimney passes through an uninsulated chase common in 1970s White Plains split-levels. We find the separation with a down-flue camera pull, then either re-sleeve with proper tensioning or switch to a rigid or flexible DuraFlex liner if the flue path won’t hold a seam.
• HeatShield stainless flex liner corrosion at the water heater connection. When a flex liner serves both a fireplace and a gas water heater, the lower BTU appliance produces acidic condensation that pools in the flex corrugations. We see this in White Plains basements with older B-vent water heaters tied into the same flue. Our fix is either a dedicated liner for the fireplace with proper sizing, or a Gelco or Olympia Chimney rigid liner with a condensate drain tee if shared venting must continue.
• CrownSaver top-mount failure letting water onto liner top. The CrownSaver cap is decent steel, but the mounting collar can work loose in our coastal Northeast wind exposure. Water runs down the flue and saturates the liner insulation blanket, which then sags and creates a cold spot. We reseat or replace the top mount, inspect the blanket, and replace any HeatShield liner section where the insulation has compressed below R-value.
• Original HeatShield clay liner spalling after 40+ years. In the Gedney Farm colonials and similar White Plains neighborhoods, we’ve pulled out original clay flue liners that were never meant to handle modern fireplace inserts. The liner flakes and spalls, narrowing the flue and creating a creosote trap. We sleeve with a HeatShield-listed stainless liner sized to the appliance, or do a partial rebuild with new flue tile if the homeowner wants to keep the original clay aesthetic.

Our HeatShield Chimney Liner & Rebuild Process

1. 1
   Call and schedule. A live person answers - no voicemail, no callback queue. We book a Level-2 camera inspection with photos you can see.
2. 2
   On-site diagnosis. Our technician runs a camera the full flue length, documents every defect, and gives you a plain-English verdict. Russell Haines reviews any questionable findings personally.
3. 3
   Parts decision. We quote OEM HeatShield components where they make sense, or quality aftermarket from DuraFlex or Gelco if the application calls for it. We explain the trade-off and let you decide - no default to the most expensive option.
4. 4
   The repair. Background-checked, uniformed techs complete most liner replacements and partial rebuilds in a single visit. Full rebuilds may need a second day for proper mortar cure.
5. 5
   Post-repair test. We run a smoke test or draft gauge check to verify proper draw, then photo-document the completed work.
6. 6
   Written guarantee. You get the 90-Day Done Right Promise in writing - if it’s not right, we make it right, no paperwork, no arguing.

Why White Plains Homeowners Call Hearthstone Chimney Co. for HeatShield Work

We’ve been in White Plains long enough to know which chimneys were built well and which were slapped together during the 1980s boom.

Our techs aren’t guessing at HeatShield part numbers. We work with the full professional-grade catalog - DuraFlex, Gelco, Olympia Chimney, Famco, Copperfield - so if a HeatShield component isn’t the right fit, we have options that are. Every job ends with photos you can see, a plain-English verdict, and the 90-Day Done Right Promise in writing. No surprises on the bill. We’ll be there when we say.
