How HeatShield Products Fail - and How We Fix Them

• Cerfractory Foam liner resurfacing cracks in the UL-Listed system. The foam shrinks slightly during curing, and in Evanston’s freeze-thaw cycles near the lakefront, hairline cracks reopen within 18-24 months. We find these with a camera scan during sweep, then re-apply Cerfractory Foam only after mechanical abrasion of the old surface. A full re-coat beats spot repair for longevity.
• Joint Repair system separation at mortar joints in pre-fab metal chimneys. HeatShield’s Joint Repair relies on adhesion to existing mortar, but factory-built units in Evanston’s 1960s-1980s housing stock often have degraded, sandy mortar beds. We remove loose material with a rotary whip during cleaning, then re-bed with fresh refractory mortar before applying the HeatShield seal. Skipping the re-bed step is why callbacks happen.
• CrownCoat degradation on concrete crowns with southern exposure. The acrylic-based CrownCoat breaks down faster on Evanston homes where UV hits the crown all afternoon, especially on shallower-pitched roofs common in the historic district near Dempster Street. We strip the failed coating during sweep access, assess crown integrity, and re-apply only after verifying no spalling concrete underneath. Sometimes the crown needs rebuild, not re-coat.
• Smoke chamber parging failure in HeatShield-treated chambers. The Cerfractory Foam parging mix can delaminate from smooth fireclay surfaces if the original application skipped scratch-coat prep. We find this during Level 2 inspection when the camera catches shadow lines in the smoke chamber. Our fix: mechanical scoring, then re-parge with a bonding agent specified for high-alkali substrates.
• Flue gas condensation accelerating liner surface breakdown. HeatShield’s resurfacing products are rated for specific flue temperatures, and oversized flues in Evanston’s converted coal-burning chimneys run too cool with modern gas inserts. We measure flue temperature and draft during inspection; if condensation is the root cause, we recommend right-sizing the liner or switching to a DuraFlex or Gelco stainless liner rather than re-coating a system that’s chemically incompatible with the appliance.

Our HeatShield Chimney Cleaning & Sweep Process

1. 1
   Call and schedule. A live person answers, collects the appliance type and any symptoms, and books a window. You’ll get a text when your tech is en route.
2. 2
   Level 2 camera inspection first. We run a camera down the flue before touching anything. Corrine Halstead and our crew have found that HeatShield-coated flues hide defects behind smooth surfaces; the camera catches what a flashlight won’t. The camera doesn’t negotiate - and neither does creosote.
3. 3
   Written price, written scope, written warranty. Before any cleaning or repair starts, you get a single-page scope with line-item pricing and the 365-Day Done Right Promise stamped at the bottom. Haven Standard Clause 1: have it in writing.
4. 4
   Cleaning with HeatShield-compatible methods. We use poly or wire whips sized to the flue diameter, avoiding aggressive mechanical damage to existing Cerfractory surfaces. Class III glazed creosote gets a chemical pretreatment, not brute force.
5. 5
   Repair or re-coat as quoted. OEM HeatShield materials when specified; quality aftermarket refractory when the application allows. Every parts choice is noted on your invoice.
6. 6
   Post-work camera verification and photo record. We camera the flue again, capture stills, and upload to your documented record under Haven Standard Clause 4. You see the footage before you see the final invoice.
