How HeatShield Products Fail, and How We Fix Them

HeatShield makes a range of repair products: the Cerfractory flue sealant, Eco-Sweep, and their crown coat. In Miami, we see specific patterns, often tied to humidity and salt air. Here’s what we actually find in the field:

• Cerfractory liner coating peeling at the smoke shelf in older masonry chimneys. Miami’s wet season drives moisture through brick, and a HeatShield coating that was applied over an already-damp flue will delaminate there first. Our fix: camera the flue, identify the failed section, and recoat only what needs it, rather than the whole liner.
• Glaze cracks in HeatShield-coated clay tile liners from salt encroachment. Homes within three miles of Biscayne Bay get salt deposition in the flue. HeatShield coatings hold up better than bare clay, but the tile itself still expands and contracts. We sweep, then inspect with a Level 2 camera to see whether the crack is cosmetic or structural before recommending any repair.
• Creosote bonding more aggressively to textured HeatShield surfaces. HeatShield’s textured coating creates micro-ridges that capture creosote faster than smooth clay. In Miami, where homeowners burn occasional fires in winter and then shut the damper in summer, glazed creosote gets rock hard. We use rotary cleaning heads suited to textured flue walls, and we will not tell you to run a DIY brush through a glazed, hardened flue.
• HeatShield crown coat cracking at the drip edge. The underside of a chimney cap has a sharp drip edge; HeatShield’s crown coat tapers there and cracks with UV exposure year-round in South Florida. We seal those cracks during a sweep when they’re hairline; anything wide enough to catch a thumbnail gets recaulked with the right high-temp product.
• Improper earlier application making the flue harder to clean evenly. We have seen HeatShield applied too thick in one pass, leaving a lumpy surface that traps soot and makes sweeping uneven. A camera inspection before we sweep tells us exactly what we are working with. If the liner was poorly applied, we tell you that plainly, with the footage to look at yourself.

One thing to know: Ashby Chimney Miami is an independent HeatShield service provider. We’re not owned by, or authorized by, the HeatShield company. That’s not a limitation. It means we tell you when a HeatShield product is fine and when a different material, like DuraFlex or Gelco, would serve you better.

Our HeatShield Chimney Sweep Process

Here’s the sequence we use on every HeatShield job in Miami, start to finish:

1. 1
   You call. A live person at (850) 787-8597 picks up, 24/7. We ask for your address, fireplace type, and the last time the flue was touched.
2. 2
   We arrive within the set window. Uniformed tech, background-checked. We bring tarps, a HEPA vacuum, and a camera unit from the van.
3. 3
   Visual inspection first. Before any sweeping, we look at the firebox, damper, and HeatShield surfaces. We note any early signs of cracking, peeling, or moisture intrusion.
4. 4
   Rotary sweep and Level 2 camera inspection. We sweep with heads matched to your flue surface, then run the camera. You see the footage. You decide what, if anything, needs doing beyond the sweep.
5. 5
   Written price for any repairs, before we start them. If we find something, you get a number in writing. No surprise invoices. No “well, now that we’re here.”
6. 6
   Cleanup, test, and the Kingswell Guarantee in writing. We leave the firebox, hearth, and floor cleaner than we found them. We test the draft. We hand you the guarantee. Done.

What HeatShield Chimney Sweep Costs in Miami

Plain dollars, as promised. These are the ranges we quote most often in the Miami market:

• Standard HeatShield sweep, Level 1 inspection included: $189 to $245
• HeatShield sweep plus Level 2 camera inspection: $265 to $325, depending on flue height and roof access
• Heavy creosote removal (glazed Stage 3, common with infrequent Miami fireplace use): $320 to $410
• HeatShield crown coat repair (minor crack sealing, not full re-coat): $180 to $360, determined by linear footage and crack depth
• Partial HeatShield Cerfractory recoat for a failed section: $450 to $900, quoted only after camera review

What moves the price: flue height, roof pitch and access, creosote stage, and whether your HeatShield surface is textured enough to require slower rotary passes. The estimate is free, in writing, and good for 30 days. Call (850) 787-8597 and we’ll give you an exact number before you commit to anything.

Why Miami Homeowners Call Ashby Chimney Miami for HeatShield Work

HeatShield owners in Miami have usually been through it once before: a technician who quoted one number over the phone, then “found” problems that tripled the invoice at the door. We run our shop differently. Every HeatShield sweep gets a written price before work starts. Every repair gets a written guarantee, the Kingswell Guarantee, which is not sold as an add-on. If a covered repair fails inside the guarantee period, we come back and fix it at no charge. That’s our 365-Day Done Right Promise, and it’s been the standard at Ashby Chimney Sweep since 2002.

Ask for Nathan Corliss personally. He grew up in Los Angeles, trained at LA Trade-Tech, and has spent nearly three decades working chimneys from Coral Gables to Brickell. He knows what humid coastal air does to a HeatShield liner, because he’s seen it hundreds of times. Tell me the price first, then explain the work, everything else is just noise, that’s how he puts it. And if you want to hear about his saltwater tank, that’s on the house too.

We also work with DuraFlex and Gelco systems, so when a HeatShield part is no longer the right call for a Miami flue, we’re not forcing a square peg. We’ll show you the footage and let the flue make the case.
