How HeatShield Products Fail - and How We Fix Them

• Cerfractory Foam liner systems crack from freeze-thaw cycling. Milford winters swing hard, and the Cerfractory Foam applied in HeatShield’s Relining Systems can develop hairline fractures where the flue meets the smoke chamber. We pull a camera to map every crack, then reapply factory-spec foam or sleeve with DuraFlex stainless where the damage is too deep for a surface repair.
• HeatShield UL-listed chimney liners corrode at the waterline. In homes near the Delaware River floodplain, we’ve found the lower sections of HeatShield’s stainless liners pit faster than inland installs. The fix is not a full replacement unless the pitting is through-wall. Often we can cut back and re-terminate with a Gelco or Olympia Chimney section, saving the owner the cost of a full reline.
• Factory-built fireplace inserts lose draft in tight Milford basements. The HeatShield Fireplace Insert series needs precise combustion-air balance. When a Milford basement is sealed up tight for winter, the insert can back-puff smoke. We test draft under real conditions, then adjust the termination height or add a code-compliant outside air kit, not a band-aid.
• Smoke chamber corbel joints fail in pre-1950s chimneys. HeatShield’s Smoke Chamber Restoration System is excellent, but it bonds poorly to oil-soaked brick. In Milford’s older homes, we encounter chimneys that burned coal or heavy oil for decades. We soda-blast the chamber first, verify porosity with a simple water-drop test, then apply the Cerfractory mix. Skipping the prep is why some local repairs fail inside two years.
• Factory dampers seize after humid Pike County summers. The cast-aluminum damper in some HeatShield fireplace systems corrodes where the pivot pin meets the frame. We stock the OEM pin and bushing kit, but we also carry a machined stainless aftermarket set from Famco that outlasts the factory part in our climate. We explain both options and let the owner choose.

Our HeatShield Fireplace Services Process

1. 1
   You call, a live person answers. We ask what you’re seeing, what you’re burning, and when the problem started. No phone tree, no callback tomorrow.
2. 2
   Level-2 camera inspection on arrival. Our technician runs a camera the full length of the flue and smoke chamber. You watch the screen. We explain what we see in plain English and email you the photos before we leave.
3. 3
   Parts decision with options. If your HeatShield component needs replacement, we quote OEM and quality aftermarket where a better option exists. No hidden markup. You approve the number before we touch a tool.
4. 4
   The repair, tested under operating conditions. We do not pack up until the fireplace is running and drafting as it should. For gas units, we check manifold pressure and thermocouple output. For wood, we burn a small test fire and verify draw.
5. 5
   Written guarantee, cleanup, and final invoice. The 90-Day Done Right Promise goes in your hand. The invoice matches the estimate. We leave the hearth cleaner than we found it.

What HeatShield Fireplace Services Costs in Milford

These are the ranges we see most often in Milford homes. Your exact price depends on access, height, and what the camera shows.

What moves the price: chimney height above two stories, concealed damage behind a surround, and whether the firebox needs refractory panel replacement. We do not discover surprises and then surprise you with the bill. Everything is agreed upfront. Call (610) 991-8179 for a free estimate.

Why Milford Homeowners Call Hearthstone Chimney Co. for HeatShield Work

We have been in Milford and Pike County for over 42 years. That means we have worked on HeatShield products installed in the 1990s, the 2000s, and last year. We know which factory batches had issues, which local installers took shortcuts, and how the Delaware River valley’s freeze-thaw cycles treat refractory materials differently than the manufacturer’s California test lab.

Our technicians are background-checked, uniformed, and carry the full range of HeatShield-compatible parts plus backup from DuraFlex, Gelco, and Olympia Chimney. Most jobs finish in one visit. The 90-Day Done Right Promise is in writing, no arguing. If it’s not right, we come back.

Russell Haines started this company in 1984 with a simple standard: find out what is wrong, say so plainly, fix it right, and stand behind it. That has not changed.
