How HeatShield Products Fail - and How We Fix Them

• Cerfractory Foam liner resurfacing separates from clay flue tiles in HeatShield’s UL-Listed relining system. In Hamden’s freeze-thaw cycle, moisture trapped behind the foam layer expands and pushes the coating away from the host tile. We see this most in homes near Lake Whitney where older clay liners were already spider-cracked. Our fix: mechanical removal of the failed section, re-application with HeatShield’s factory-specified bonding wash, and a post-cure camera verification.
• JointShield gap-filling compound shrinks in flues with chronic backdraft issues. The HeatShield JointShield product is designed to seal mortar joints between flue tiles, but sustained negative pressure from a poorly sealed fireplace pulls combustion gases through before the compound fully cures. We diagnose the draft problem first, then re-apply JointShield only after correcting air flow. In Hamden’s tighter new construction near Mix Avenue, this combination failure is more common than owners expect.
• HeatShield Pro-Formance stainless liners develop creosote bridging at flex points. The Pro-Formance line uses corrugated sections that flex around offsets, but those corrugations trap glazed creosote in homes burning unseasoned oak or maple, which is what most Hamden homeowners have delivered. We use rotary poly chains, not wire brushes, to clean Pro-Formance liners without scoring the stainless surface, then verify clearance with a video scan.
• Factory-applied refractory coatings delaminate above the smoke shelf in deep fireboxes. HeatShield’s spray-applied refractory faces its toughest thermal shock right where the smoke shelf meets the firebox rear wall. After years of Hamden winters with daily burns, the interface cracks and flakes. We grind to sound substrate, apply a heat-cured refractory patch, and match the original thickness spec rather than building up excess material that traps heat.
• HeatShield crown sealant fails at drip-edge terminations where squirrels have chewed. The flexible crown coating works until rodents breach it, which happens regularly near Hamden’s wooded lots around Sleeping Giant. We remove the damaged sealant, repair the concrete crown substrate if needed, then re-apply HeatShield crown product with reinforced mesh at vulnerable edges.

Our HeatShield Chimney Cleaning & Sweep Process

1. 1
   Call and schedule. A live person answers, 24 hours a day. We ask about your HeatShield product age, last service date, and what you’re noticing. We quote a range upfront.
2. 2
   Level-2 camera inspection on arrival. Our technician runs a video scan from firebox to cap, capturing the condition of your specific HeatShield system. You see the footage. We explain what we’re looking at in plain English.
3. 3
   Diagnosis and parts decision. If HeatShield OEM material is available and appropriate, we use it. If a quality aftermarket solution from our DuraFlex or Gelco inventory meets the same spec at better value, we explain the trade-off and let you decide. No surprises.
4. 4
   The sweep and any repair. Creosote and soot removal first, then repair work if needed. Most HeatShield jobs finish in one visit. We protect floors and furniture, and we clean up after ourselves.
5. 5
   Post-work camera verification and documentation. We scan again to confirm the repair. You get photos and a written condition report.
6. 6
   The 90-Day Done Right Promise. If it’s not right, we come back. In writing. No arguing.

We’ve been working Hamden chimneys for over 42 years, from the pre-war brick stacks near the Farmington Canal to the raised ranches off Skiff Street.

We’re an independent HeatShield service provider, not a factory affiliate, which means we source what actually fits your system, not what a corporate program pushes. Our 90-Day Done Right Promise is in writing. Our technicians are background-checked, uniformed, and trained on HeatShield, DuraFlex, and Gelco product lines. Most jobs finish in one visit. The price we quote is the price on the invoice. If it’s there, we’ll find it. If it doesn’t need fixing, we’ll tell you that too.
