We’re Flint Chimney Co Miami, part of the Garrison Partners family founded in 2002. As an independent HeatShield service provider, we’re not a HeatShield affiliate or authorized warranty center. What we are is a crew that has swept and inspected hundreds of HeatShield flues in Miami, from Coconut Grove to Little Havana. Hank Delano runs the crew, and he’s the one you’ll talk to if the inspection turns up something that needs a closer look. Tell him what you saw, he’ll tell you what it costs.

Key Takeaways

• HeatShield chimney sweep in Miami costs $189 – $279 for a standard job, with a written price before work starts.
• HeatShield’s Cerfractory joint seal is the material that fails most often in Miami’s humid coastal air, and a sweep is when we catch it early.
• You get a full Level 1 or Level 2 inspection with every sweep, not just a brushing.
• Our 365-Day Done Right Promise covers every repair we make, in writing, for a full year.

How HeatShield Products Fail – and How We Fix Them

HeatShield makes two distinct systems: a cast-in-place Cerfractory liner and a resurfacing joint seal, plus protective coatings. In Miami, the failure patterns are different from what you’d see in a dry mountain climate. Here’s what we actually find on HeatShield jobs in this city:

• Cerfractory joint seal erosion in older Miami fireplaces. The HeatShield Cerfractory seal bonds flue tile joints. In Miami’s salt-laden air and summer humidity, water vapor works into the mortar joints behind the seal, and over five to ten years the seal starts to lift at the edges. We see this most on HeatShield Eco-Elite and HeatShield Resurfacing applications done more than a decade ago. A sweep won’t fix it, but a Level 2 inspection during the sweep catches it before the gap widens. The fix is a proper re-application of the joint seal, which we quote in writing before touching a trowel.
• Creosote bonding to Cerfractory surface texture. Cerfractory cures with a slightly porous surface, unlike smooth stainless. That’s fine for durability, but it gives creosote more to grip on unseasoned wood fires. We see third-stage glazed creosote on HeatShield liners in Miami homes that burn a lot of oak with the air shut down. Standard flat-wire brushing doesn’t always get it all. We use a rotary whip head with nylon lines when the deposit is heavy, which cleans the Cerfractory texture without abrading the surface.
• Damper seat warping from Miami humidity, not HeatShield failure. This one’s not the liner’s fault. Steel damper frames corrode and warp in Miami’s wet season, and homeowners sometimes blame the HeatShield work done years ago. We check the damper separately during a sweep. If the seat’s warped, we replace the damper or the top-sealing cap assembly, and the HeatShield liner stays intact. It’s a cheaper fix than people expect, usually $220 – $390 with the part.
• HeatShield coating delamination on the smoke chamber. HeatShield’s chamber coating is the thinner, spray-on application for the smoke chamber above the firebox. In Miami, we’ve seen it delaminate in layers when the original chamber was never parge-coated first. It looks like peeling paint on the chamber walls. The sweep itself doesn’t cause it, but a camera inspection shows it plainly. We document it, give you the photos, and tell you straight if it can wait. If it can’t, a re-coat with proper surface prep is the fix.
• Improper previous HeatShield application we only see with a camera. This happens more than HeatShield’s own documentation would suggest. We’ve done Miami sweeps where the Cerfractory was clearly poured by someone who skipped the primer pass, and the liner has hairline cracking within three years. A visual-only inspection misses it. Every HeatShield sweep we do includes a camera pass up the flue, because the camera is the only way to see whether the original application was done right. If it wasn’t, we can usually tell you within 20 minutes what the honest options are.

Our HeatShield Chimney Sweep Process

Every HeatShield job follows the same sequence, so you always know where you stand:

1. 1
   Call and book. A live person answers at (786) 305-7861, 24/7. We schedule the visit, give you a two-hour arrival window, and tell you what to expect.
2. 2
   On-site assessment. The tech walks the fireplace, checks the HeatShield liner visually from the firebox, inspects the damper, and lays out what the sweep will include.
3. 3
   Written price before work. No exceptions. The number you approve is the number you pay. If the assessment turns up something beyond a standard sweep, like heavy glazed creosote, the revised price is documented and agreed before any tool comes off the truck.
4. 4
   Sweep and camera inspection. We brush the full HeatShield flue with the appropriate head for the deposit type, then run a camera from firebox to cap. Your photos are included in the report, not an upsell.
5. 5
   Findings and options. If the camera shows a failing joint seal, coating issue, or cracked tile behind the HeatShield layer, we explain it in plain words. You get the exact cost to fix it. We tell you plainly if it can wait.
6. 6
   Cleanup and guarantee. Drop cloths, HEPA vac, no dust in the living room. Any repair we make gets the 365-Day Done Right Promise in writing, with a free return visit if it fails within the year.

What HeatShield Chimney Sweep Costs in Miami

Here are the real numbers for common HeatShield scenarios in Miami:

• Standard HeatShield chimney sweep with Level 1 inspection: $189 – $279. This covers brushing the full flue, firebox cleanup, and a visual inspection.
• HeatShield sweep with Level 2 camera inspection: $299 – $399. We recommend this for any Miami home that hasn’t had the flue camera-scoped in five years.
• Heavy glazed creosote removal on HeatShield Cerfractory: $350 – $500. Rotary whip head, more passes, longer run time.
• HeatShield joint seal re-application (if the sweep uncovers erosion): $1,200 – $2,800 depending on flue height and extent. Written quote after camera inspection, always.

What moves the price: flue height, deposit severity, and whether a previous application failed. You’ll know the exact number before we start. Call (786) 305-7861 for a free estimate on your specific fireplace.
