Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
HeatShield Chimney Liner & Rebuild in Brentwood: What to Know First
HeatShield chimney liner repair and rebuild in Brentwood runs $1,800 to $6,500 depending on whether we’re resurfacing a section of flue or tearing out and replacing the whole liner. Most jobs take one to two days on site, and we’ll give you the straight number before any work starts. If the liner can be safely resurfaced, we’ll say so. If it needs to come out, we’ll show you the camera footage that proves it.
This page is for Brentwood homeowners dealing with a HeatShield liner that’s spalling, cracking, or failing a chimney inspection. Call (934) 935-3847 and Wendell or one of his crew will answer. Not a call center.
How HeatShield Products Fail - and How We Fix Them
HeatShield’s Cerfractory system works differently than rigid metal liners, and it fails differently too. Here’s what we actually see in Brentwood flues.
- Spalling in the HeatShield Cerfractory Flue Sealant. The ceramic compound HeatShield uses can start flaking off the original clay liner within five to eight years, especially in unlined masonry that runs hot. We see this a lot on capes near Brentwood State Park where fireplaces get pushed hard in January. The fix is often a re-application after proper surface prep, not a full tear-out.
- Joint separation showing up as vertical cracks. HeatShield’s material is only as good as the bond between it and the old clay tile beneath. When the original mortar joints shift, the HeatShield surface cracks right along those lines. Camera inspection shows it clearly: a long vertical crack following a clay tile seam. Resurfacing over a moving joint fails again, so we address the joint movement first.
- Water intrusion compromising the HeatShield bond. Brentwood gets real rain in spring and fall. If the chimney cap is damaged or the crown is cracked, water runs down the flue and works between the HeatShield surface and the clay tile. The material lifts. No HeatShield repair holds if the water problem isn’t fixed first, which is why we inspect the cap and crown on every HeatShield job.
- HeatShield over previously glazed creosote. Third-degree creosote doesn’t just brush out. If someone tried to resurface a flue without fully removing the glaze first, the HeatShield can’t bond. We’ve found this on chimneys in Brentwood’s older neighborhoods where fires burned for decades before anyone resurfaced. The old surface has to be mechanically cleaned before any new application goes in.
- Deterioration around the smoke chamber. HeatShield’s product works in the flue, but the smoke chamber below it often gets skipped by other companies. A Brentwood chimney that passes a flue camera inspection can still draft poorly because the smoke chamber is rough and catching soot. We resurface both when they need it, not just the flue section that shows up on the invoice.
Our HeatShield Chimney Liner & Rebuild Process
- 1
We put eyes on it. Camera goes down the flue, top to bottom. You see the footage too. No verdict until we’ve looked at the actual surface, not just a photo from last year.
- 2
We give you a plain-English writeup. Here’s what the camera showed, here’s what it means, here’s what we’d do and what we’d leave alone. The number on the quote is the number on the invoice.
- 3
Prep work matters more than the product. The old surface gets cleaned and profiled so the HeatShield material has something real to grip. Skipping prep is how resurfacing jobs fail in two years.
- 4
The repair or rebuild. Smaller spalls get resurfaced with HeatShield’s Cerfractory compound. Badly deteriorated flues get a full rebuild, usually with a stainless liner from DuraFlex or Gelco when HeatShield resurfacing won’t hold.
- 5
We test it. Draft check, visual review, and we run the camera again so you can see the finished surface before we pack up.
- 6
The 90-Day Done Right Promise goes in writing. If something isn’t right, one call brings us back. That’s stamped on every job we do in Brentwood.
What HeatShield Chimney Liner & Rebuild Costs in Brentwood
Here’s the honest range we quote in Brentwood:
- HeatShield resurfacing, small section: $1,800 to $2,600 - covers minor spalling in a short flue run with good access.
- HeatShield full flue resurfacing: $3,200 to $4,800 - entire flue re-lined with HeatShield after proper prep.
- Full chimney rebuild with stainless liner: $4,500 to $6,500 - when the clay tile is gone and resurfacing won’t hold, we tear out and reline, often with DuraFlex or Gelco.
- Smoke chamber resurfacing (add-on): $600 to $1,100 - done at the same time whenever it shows rough.
What moves the number: access, roof pitch, how much prep the old surface needs, and whether the crown or cap needs work before anything else. Call (934) 935-3847 for a free estimate. We’ll tell you if the job can wait.
Why Brentwood Homeowners Call Top Hat Chimney for HeatShield Work
We’ve been working Brentwood chimneys since 1999, and Wendell Pike puts his name on every job we do. That’s not a marketing line. He runs into you at the hardware store. He drives the same roads you do. If the HeatShield work we did doesn’t hold up, you don’t have to chase a franchise. You call the same number and we come back. That’s the 90-Day Done Right Promise, in writing, on every single job.
We’re an independent HeatShield service provider, which means we’ll recommend what’s actually right for your chimney, not what a brand program tells us to push. Sometimes that’s HeatShield. Sometimes it’s a DuraFlex stainless liner or a Gelco rebuild because the flue is beyond resurfacing. The camera footage tells us which one, and we show you that footage every time, no exceptions. Ask anyone on your street.
FAQs
HeatShield offers a limited warranty on their Cerfractory material when installed to spec, and we honor the prep and application standards that keep that warranty valid. What we add on top is our own 90-Day Done Right Promise, in writing, so you’re not stuck sorting out manufacturer paperwork if something’s not right. Call (934) 935-3847 and we’ll walk you through what your existing warranty covers before we touch anything.
Resurfacing a small section often takes a single day. Full flue resurfacing or a rebuild is typically one to two days on site. The variable is prep: if the old surface needs heavy cleaning before new HeatShield material goes on, that’s time well spent, and we’ll tell you upfront what the day count looks like.
Spalling smaller than your palm with no structural movement behind it can usually be resurfaced. Cracks that follow the old clay tile joints or surface lifting from water intrusion usually mean the flue needs more than a patch. We don’t make that call from the ground. We run the camera, you watch the footage, and we give you the verdict in plain English. If it needs doing, we’ll do it right. If it doesn’t, we’ll tell you that too.
Once a year, burn or no burn. Chimneys break in the off-season too, and Brentwood’s spring rain gets into cracked crowns and caps before you notice it inside. Annual sweeping also gives us eyes on the HeatShield surface so small spalling gets caught before it turns into a rebuild. Call (934) 935-3847 to get on the schedule.
Yes, free. Bring us any written estimate for HeatShield or chimney liner work and we’ll tell you what’s actually needed and what isn’t. No obligation, no pressure. That’s how we’ve done business in Brentwood since 1999.
