How HeatShield Products Fail – and How We Fix Them

HeatShield is a good product, but it’s not magic. Here’s what we actually see on HeatShield-lined chimneys across Los Angeles, and what we do about it.

• CeCure sleeve joints blistering at the seam. The CeCure line uses a ceramic-fiber sleeve soaked in HeatShield’s Cerfractory sealant. On older installs in LA, we find blistering where the sleeve seam faced the flue’s hot side. Cause is usually a first-year fire season that ran hotter than the installer expected. Our fix is a seam patch with HeatShield’s own repair compound when the underlying sleeve is sound, or a re-sleeve quote when it isn’t. We send pictures before we touch anything.
• Joint compound flaking on flues that vent gas logs. Gas log sets burn cooler, which sounds fine, but the constant low heat and moisture cycling loosens the joint compound on HeatShield’s Foam application. In Sherman Oaks and Studio City we see this often on homes with vented gas logs. We clean the flue, document every flake with the camera, and resurface only if the coating has actually separated. If it’s just surface dust, we tell you so and leave it alone.
• Creosote bonding to the ceramic surface after a wet burn season. HeatShield’s finish is smoother than raw clay tile, but not slick. After two or three seasons in a damp chimney, stage-two creosote can bond to it like tar. This is common in the older Craftsman bungalows of Atwater Village and Highland Park, where chimneys often lack a proper cap. We remove it with a rotary brush and solvent cleaner rated for ceramic-coated flues, then quote you a chimney cap if you don’t have one.
• Liner separation behind the firebox damper. The HeatShield application starts above the smoke shelf, which means the transition area behind the damper is a common failure point. Shifting from Santa Ana wind pressure cycles can crack the coating where it meets the clay tile. Our camera spots this in about ten seconds. The fix is a localized patch, not a full reline, and we’ll show you the video before quoting it.
• Aftermarket patch mismatches from previous service calls. We see chimneys where someone used a generic refractory cement on a HeatShield liner. It usually doesn’t bond and starts crumbling within a year. We remove the bad patch, prep the surface, and use material matched to HeatShield’s chemistry. The brand of patching compound matters more than most homeowners realize.

Our HeatShield Chimney Sweep Process

Here’s how a HeatShield job goes when you call Ashby Chimney Los Angeles. No surprises, no mystery charges.

1. 1
   Call and schedule. You reach a person, not a phone tree. We ask the basics: last sweep, fireplace type, anything worrying you. If you know it’s a HeatShield liner, we note it before we arrive.
2. 2
   We show up in the window. Uniformed, background-checked technician. We lay down drop cloths and set up the HEPA vac before anything else.
3. 3
   Camera inspection first. We run a camera up the flue before the brush touches it. On a HeatShield liner, this tells us the coating’s condition, the creosote grade, and whether there’s anything that needs a repair quote instead of just a cleaning.
4. 4
   Written price before work. After the camera, we tell you exactly what the sweep costs and whether we found anything that needs attention. You approve the number before we start. If we recommend a patch or resurface, you get photos and a written quote.
5. 5
   The sweep itself. Rotary brush and HEPA vacuum, sized to the flue. On HeatShield liners we use plastic or poly brushes, never steel, so the ceramic surface isn’t scarred. Firebox, smoke shelf, damper, and ash pit get cleaned too.
6. 6
   Post-sweep report and guarantee. We hand you a written report with before-and-after photos and a written guarantee on any repair work. If a covered repair fails, we come back and fix it free under the 365-Day Done Right Promise.

What HeatShield Chimney Sweep Costs in Los Angeles

Say the price first, put the promise in writing, and leave the firebox cleaner than you found it. That’s how we work, so here are the numbers for HeatShield chimneys.

• Standard sweep, clean flue: $189 to $229. One flue, normal creosote, working damper, fireplace or wood stove.
• Heavy creosote removal (stage two or three): $249 to $329. Takes longer and uses chemical treatment plus repeated brush passes. More common on HeatShield liners that have gone two-plus seasons without service.
• Sweep plus camera inspection report: Included. We don’t charge extra to show you what we saw. The camera report is part of the job.
• HeatShield patch or seam repair: $150 to $450 depending on location and size. Quoted separately, in writing, with video or photos before you approve anything.
• Full re-sleeve or resurfacing: $2,800 to $6,500 depending on flue height and access. We’ll tell you honestly if your liner has years left and doesn’t need this yet.

What moves the price: flue height, creosote grade, roof access difficulty, and whether we find repair work during the camera inspection. Nothing gets added without a written quote and your signature. Call (213) 652-7061 for an exact number, estimates are free.
