Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

How HeatShield Products Fail - and How We Fix Them
- HeatShield Cerfractory Flue Liner: thermal-shock cracking in the smoke chamber. The Cerfractory slurry cures to a ceramic-refractory hybrid that’s excellent when intact, but the transition from firebox to flue liner (the smoke chamber) sees the steepest temperature swings. In Pasadena, where evening temperature drops of 30°F or more are common from October through March, that thermal cycling opens hairline fractures that we catch on camera during a Level 2 inspection. We re-coat with factory-specified Cerfractory mix or recommend partial rebuild if the substrate has shifted.
- HeatShield UL Listed Relining System: delamination at the flue collar connection. The UL Listed system’s bond to the existing clay flue depends on surface prep most installers rushed in the 2015-2019 Pasadena building boom. We find collars working loose where the original crew didn’t scarify the clay adequately. Our fix: remove the collar, re-prep the substrate to NFPA 211 standards, and re-bond with fresh HeatShield-compatible compound or transition to a DuraFlex or Gelco stainless liner if the clay is too far gone.
- HeatShield Refractory Panels in factory-built fireplaces: corner spalling from gas-log impingement. Homeowners who converted to vented gas logs without adjusting the burner position send a concentrated flame against the panel corners. The refractory surface flakes off in wedges, exposing the insulating layer beneath. We source OEM HeatShield panels through our Haven buying network or fabricate matched refractory shapes when the series has been discontinued.
- HeatShield Smoke Chamber Repair: slumping parging in pre-1940s Pasadena chimneys. The corbelled brick smoke chambers in Bungalow Heaven and other craftsman neighborhoods weren’t built for modern insert loads. HeatShield’s smoke chamber sealant fills the corbels, but if the original parging was gypsum-based (common in 1920s Pasadena construction), it turns to powder behind the sealant. We remove the failed substrate, re-parge with proper refractory mortar, then apply HeatShield sealant over sound material.
- HeatShield Cast Damper Frames: rust-jacking in coastal-influence zones. Pasadena’s winter marine layer pushes humidity up against metal components in exterior chimneys, especially north-facing flues in the Linda Vista and San Rafael hills. The cast iron damper frame swells as rust forms, freezing the blade. We free the mechanism, assess the frame integrity, and replace with a stainless assembly from our DuraFlex or Gelco inventory when the original HeatShield casting is no longer serviceable.
Our HeatShield Fireplace Services Process

- 1
Call and schedule. A live person answers, 24 hours a day. We book a window, assign a named technician, and text when they’re en route.
- 2
Camera-scan inspection. NFPA 211 Level 2 inspection with full flue camera documentation. Corrine Halstead and her crew show you the footage before quoting anything. The camera doesn’t negotiate - it just shows what’s there.
- 3
Written price, written scope. We deliver a written price, written scope of work, and written warranty before any tool touches your fireplace. Haven Standard Clause 1: have it in writing.
- 4
Parts decision with full context. We stock HeatShield-compatible materials and maintain relationships with DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield suppliers. If OEM HeatShield parts are back-ordered or discontinued, we explain the aftermarket equivalent and warranty implications plainly.
- 5
Repair and live testing. The work is performed by background-checked, uniformed technicians. Gas systems are leak-tested and draft-verified; wood systems are burned in under observation where appropriate.
- 6
Documentation and follow-up. You receive a photo record of completed work, readings, and a stamped warranty document. Haven Standard Clause 4 requires this archive; we’ve done it on every job since 2009.

Why Pasadena Homeowners Call Level Two Chimney Pasadena for HeatShield Work

We’ve serviced homes throughout Pasadena for years, including older craftsman properties near Bungalow Heaven where the masonry work rarely surprises us anymore. Corrine Halstead learned the trade through Queensborough Community College’s building maintenance and HVAC programs, then put in years on actual rooftops before building this crew. That background shows in how we handle HeatShield jobs: we know the difference between a slurry that can be re-coated and a substrate that needs stripping, and we say so before quoting.
The 365-Day Done Right Promise backs every job. Our materials come through Haven’s buying network specifically to keep customer prices honest. If you have a competitor’s written estimate, we’ll give you a free second opinion. And every visit includes the documented photo record we’ve maintained since 2009 - Haven Standard Clause 4, non-negotiable.
FAQs
No. As an independent HeatShield service provider with no manufacturer affiliation, our repairs carry our own 365-Day Done Right Promise, not HeatShield’s original warranty. If your installation is recent enough to fall under HeatShield’s material warranty, we document the condition and can advise whether a factory claim is viable, but we don’t process those claims on your behalf. Call (213) 459-6058 for a free estimate - we’ll inspect and explain your actual coverage.
Sometimes, but not always. For discontinued refractory panels or early collar designs, we fabricate matched replacements from compatible refractory materials or transition to DuraFlex or Gelco components that interface correctly with your remaining HeatShield system. We explain the trade-offs in writing before you decide. Call (213) 459-6058 for a free estimate.
We know after the camera inspection. Hairline cracking in sound substrate gets re-coated; delamination over more than 30% of the surface, or any exposed structural clay shifting, means replacement. We show you the footage and quote both scenarios when the line is close. Call (213) 459-6058 for a free estimate.
Most smoke chamber or localized flue repairs are completed in one day. Full relining or extensive firebox rebuilds may run two days, with your fireplace out of service overnight. We tell you the schedule in the written scope, not after arrival. Call (213) 459-6058 for a free estimate.
Deferred maintenance on any gas fireplace risks delayed ignition, sooting, or carbon monoxide spillage from incomplete combustion. With HeatShield components specifically, refractory panel spalling can redirect flame patterns and overheat the firebox wrapper. We catch this on camera during routine service. The fix is usually minor if found early; ignored, it can require insert replacement. Call (213) 459-6058 for a free estimate.
