How HeatShield Products Fail - and How We Fix Them

• HeatShield cerfractory flue sealant delamination: On HeatShield’s CeaseFire and FireGuard resurfacing jobs, we sometimes find the cerfractory coating pulling away from the original clay tile in hairline sheets. Washington’s humidity swings make the underlying tile expand and contract, and the bond line is where it shows. Our fix starts with a camera pass to map every separation, then a mechanical cleaning at reduced RPM so we don’t peel off more material, then documentation of the exact delamination boundaries for the homeowner. If the delamination is under 30% of the flue, a re-application often holds. If it’s past that, replacement is the honest recommendation.
• CrownSeal shrinkage cracks at the flue collar: HeatShield CrownSeal is a good product, but we see shrinkage cracks at the joint where it meets the clay flue liner, especially on Washington rowhomes with full southern exposure. Water gets behind the seal and freezes in January, pushing the crack open a millimeter at a time. We clean out the loose material, verify the underlying crown is sound, and re-seal with a flexible refractory caulk rated for the same temperature range. The written quote includes exactly what we’re removing and what we’re putting back.
• Cerfractory buildup in the smoke chamber: On HeatShield resurfaced chimneys, excess cerfractory slurry can pool in the smoke chamber shoulders during application. That creates a rough, uneven profile that traps soot faster than smooth tile. When we sweep a HeatShield chimney in Washington, we camera the smoke chamber from below and above, then remove the excess with vacuum-assisted brushing. It’s a detail most sweeps miss because they don’t look for it.
• Joint pitting on older HeatShield liner installations: HeatShield liners installed before about 2012 sometimes show pitting at the butt joints where the product was applied too thin. The pitting catches creosote and makes standard brushing ineffective. We use a rotary brush with a poly line at controlled speed, then follow with a second camera sweep to confirm the joints are clear. Photos before and after are included in the record, per Clause 4 of the Haven Standard.
• Third-degree creosote glazing on HeatShield interiors: HeatShield surfaces are rougher than glazed clay tile, which means creosote adheres more readily. In Washington homes that burn unseasoned oak, we regularly find glossy third-degree creosote on the cerfractory surface. That requires a chemical treatment, usually a two-stage application of a creosote conditioner, followed by mechanical removal. This isn’t a job for a drill brush. We run it over two visits when the glaze is thick, and the written price covers both.

Our HeatShield Chimney Cleaning & Sweep Process

A HeatShield chimney isn’t a standard masonry flue, so we don’t sweep it like one. Here’s how a job goes, start to finish:

1. 1
   Call and written price promise: You tell us your address, chimney type, and last sweep date. We give you a written price before we schedule, covering the sweep, the camera inspection, and any known extras. That’s Clause 1 of the Haven Standard: written scope, written price, written warranty.
2. 2
   Arrival and setup: A named, background-checked tech arrives in uniform. You get a text before we head your way. Drop cloths go down, vacuum goes on, and the roof access gets set up.
3. 3
   Camera inspection first: We run the camera down the flue before we sweep. On a HeatShield system, we’re looking specifically for delamination, joint pitting, crown seal cracks, and glazed creosote. You see the footage in real time. The camera doesn’t lie.
4. 4
   Reduced-speed mechanical cleaning: We use a rotary brush at lower RPM than we’d use on raw clay tile, with vacuum capture running the whole time. This removes creosote and soot without risking further delamination of the cerfractory surface.
5. 5
   Post-sweep camera pass and documentation: We send the camera down again and compare before and after side by side. You get the photo record, the written condition report, and the written warranty, all in one package before we pack up.
6. 6
   Cleanup and payment: We leave the firebox and hearth cleaner than we found them, review the record with you, and take payment. The 365-Day Done Right Promise applies to the entire job.

What moves the price: how much creosote is packed in, whether the delamination needs re-application, and how hard the roof access is. We don’t charge extra for “difficult” flues as a line item. Call (240) 621-1264 and we’ll put the exact number in writing.

Why Washington Homeowners Call Level Two Chimney Washington for HeatShield Work

Most chimney companies in Washington sweep a HeatShield liner the same way they sweep a raw clay flue, and that’s exactly how the cerfractory coating gets damaged. We’ve been camera-documenting chimneys since 2009, which is years before most companies in this city would even show a homeowner their own flue on screen. Corrine Halstead runs our Washington operation with a simple rule: write down the finding, the photo reference, and the price before asking a homeowner to decide anything. We service HeatShield as an independent HeatShield service provider, and we keep DuraFlex and Gelco materials in the same truck, so if your liner is beyond patchwork, you get options and a written price for every one. The 365-Day Done Right Promise applies to every HeatShield job we do, no fine print.
