How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Flue Sealant delamination in the smoke chamber. The Cerfractory coating, common in Alpharetta homes built 2010-2018, can separate from the substrate when subjected to repeated thermal cycling plus our humid Georgia shoulder seasons. We see this most often in two-story homes off Webb Bridge Road where the chimney runs exterior with minimal insulation. We remove the failed coating, recondition the surface, and reapply to manufacturer thickness spec - or recommend a stainless liner if the underlying masonry is too compromised.
• HeatShield UL Listing compromised by improper original installation. Some Alpharetta installations from the 2015-2019 building boom used Cerfractory in applications beyond its listed clearance or temperature rating, particularly in zero-clearance fireplace installations. The material itself didn’t fail - it was put somewhere it was never tested to be. We document the mismatch with camera footage, quote a code-compliant solution in writing, and handle the rebuild or liner replacement to restore proper UL coverage.
• Thermal expansion cracks in HeatShield-relined clay flues. When a clay flue was previously coated rather than fully lined, the differential expansion rate between old clay and new cerfractory material creates hairline fractures after 8-12 years of Alpharetta freeze-thaw cycles. These cracks don’t always show on external inspection. We find them with our camera scan, then recommend either a fresh Cerfractory application or a move to flexible stainless steel depending on crack depth and location.
• Smoke chamber parging failure above HeatShield relined flues. The parged smoke chamber is the transition zone above your firebox, and it’s where HeatShield work often stops while masonry deterioration continues. In Alpharetta’s older Windward and Country Club of the South builds, we’ve found the parging crumbling behind a seemingly intact flue coating. We pull the camera back, show you the gap, and rebuild the chamber with proper refractory material before any new liner goes in.
• HeatShield-to-metal transition corrosion at the thimble. Where a Cerfractory-lined clay flue meets a metal thimble or appliance connector, condensation from Alpharetta’s high-humidity shoulder seasons accelerates rust at the junction. This isn’t a liner failure exactly, but it destroys the seal and can spill combustion gases. We replace the corroded thimble with a proper stainless transition, sealed and documented, or move to a full stainless liner system if the damage has propagated.

Our HeatShield Chimney Liner & Rebuild Process

1. 1
   Level 2 camera inspection. We run the camera the full flue length, document every crack, delamination, and joint gap, and show you the footage before quoting. Clause 4 of the Haven Standard requires this photo record on every job - we’ve done it since 2009.
2. 2
   Written scope and price. Corrine or a senior tech delivers a written price, written scope, and written warranty before any work starts. Haven Standard Clause 1: have it in writing. No verbal estimates, no “we’ll see when we get in there.”
3. 3
   Parts decision: OEM HeatShield or quality aftermarket. We source HeatShield Cerfractory direct when the application calls for it, but we also keep DuraFlex and Gelco stainless liners in stock for situations where a coating repair won’t last. We explain the trade-off in dollars and years, and you choose.
4. 4
   Repair or rebuild execution. Liner replacement gets pulled and replaced same day. Partial rebuilds - smoke chamber, crown, above-the-roof work - are scheduled with weather contingencies built in. Background-checked, uniformed technicians; license number on every page; text when we’re en route.
5. 5
   Post-repair camera verification and draft test. We camera the finished flue, run a draft and spillage test, and add the documentation to your record. You get photos, readings, and a written warranty with the 365-Day Done Right Promise stamped on it.
6. 6
   Cleanup and archive. Your documented record goes into our archive and yours. If you sell the home, need insurance documentation, or want a second opinion later, the file is there.

Why Alpharetta Homeowners Call Emberly Chimney Cleaners Alpharetta for HeatShield Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a significant share of those have been in Alpharetta neighborhoods where HeatShield systems were specified by builders during the 2010-2018 construction wave. Corrine Halstead and her crew know which flue configurations local builders favored in different eras and where the problem spots tend to hide - the exterior chimneys with inadequate clearance, the zero-clearance installs pushed beyond listing, the smoke chambers never properly parged to begin with.

We’re an independent HeatShield service provider, not a factory authorized dealer. That means we can recommend Cerfractory when it’s the right fix and DuraFlex or Gelco stainless when it’s not, without channel pressure to sell one brand’s solution. The camera doesn’t soften anything, and neither do I. You get the footage, the finding, the written price, and the warranty - every time, no exceptions.
