How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner resurfacing on Bedford’s pre-1980 masonry chimneys often develops hairline cracking where the foam meets the terracotta shoulder, especially after freeze-thaw cycles in our hard Westchester winters. The foam shrinks slightly at the edges over five to seven years, opening a gap that collects acidic condensate from gas inserts. We cut back to sound substrate, re-apply with the manufacturer’s specified bonding wash, and verify with a pull-camera before we close up.
• HeatShield UL-Listed stainless steel liners in the HS-Flex series can suffer corrugated-wall fatigue at the first offset above the smoke chamber, particularly in chimneys with 30-degree or greater bends common in Bedford’s center-hall colonials. The flex memory works against itself after repeated thermal cycling. We replace the stressed section with rigid DuraFlex or Gelco rigid pipe at the offset, maintaining HeatShield compatibility while eliminating the failure point.
• HeatShield poured refractory jobs occasionally exhibit surface spalling when the original mix was applied too thin above the firebox - we see this in homes near the Bedford-Bedford Hills line where quick winter repairs were done before the product fully cured. The fix is mechanical removal of the compromised layer and a full re-pour to the specified 5/8-inch minimum thickness, not a skim-coat patch that’ll fail again in two seasons.
• HeatShield tee connections on wood-burning installations loosen at the snout-to-liner joint after a decade of ash abrasion and thermal expansion. The tee body itself is usually sound; the failure is in the compression seal. We source OEM-spec replacement snout assemblies rather than field-fabricating, which preserves the UL listing and keeps your homeowner’s insurance valid.
• HeatShield smooth-wall relining in oil-to-gas conversion chimneys can show pinhole corrosion at the condensate line when the original sizing was marginal for the new appliance’s lower flue temperature. Bedford’s older homes often have 6-inch flues forced to handle 80% efficient equipment. We resize with a properly spec’d HeatShield liner or, when the flue is too far gone, recommend a full DuraFlex or Gelco stainless replacement with the correct diameter for your BTU load.

Our HeatShield Chimney Liner & Rebuild Process

1. 1
   Call and schedule. A live person answers (914) 409-9387 24/7. We book a two-hour arrival window, not “sometime Tuesday.”
2. 2
   Level-2 camera inspection. Our tech runs a full-color, pan-tilt camera from top to bottom. You see the footage in real time. We mark every defect with a timestamp and explain what we’re looking at in plain English - no jargon, no scare tactics.
3. 3
   Parts decision with options. If HeatShield OEM parts are available and make sense for your job, we use them. If a quality aftermarket equivalent from DuraFlex or Gelco solves the problem more durably or cost-effectively, we tell you that straight and let you choose. We never substitute builder-grade materials.
4. 4
   The repair. Our background-checked, uniformed technicians work with drop cloths, HEPA vacuums, and the right tools for HeatShield’s specific bonding and curing requirements. Most liner and rebuild jobs finish in one visit.
5. 5
   Post-repair verification. We camera the repair, smoke-test or pressure-test per code, and show you the after photos next to the befores. You know it’s right because you saw it.
6. 6
   Written guarantee and cleanup. The 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back. Then we sweep up like we were never there.

What HeatShield Chimney Liner & Rebuild Costs in Bedford

What moves the price: accessibility (steep roof pitch, tight setbacks on Bedford’s smaller lots), extent of terracotta damage hidden until camera inspection, and whether the chimney serves a wood burner, gas, or oil appliance with different liner specs. We give you the full number before we start - no surprises on the bill. Call (914) 409-9387 for a free estimate.
