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.

AfterHeatShield Chimney Cap & Crown in Brentwood: What to Know First
We repair, replace, and install HeatShield chimney caps and crowns across Brentwood, and we do it as an independent HeatShield service provider, meaning we work on the system without being tied to a manufacturer script. Most HeatShield cap and crown jobs take half a day once we’re on the roof. A crown coating runs $400 to $700, a full crown rebuild with a proper pour runs $900 to $1,800, and a new cap or cap replacement runs $250 to $850 depending on flue size and whether it’s a single-flue or multi-flue setup. If you own a HeatShield system and water’s getting in or the cap has seen better days, this page tells you exactly what’s going on and what it’ll take to make it right. Call us at (934) 935-3847 and a live person answers, day or night.
How HeatShield Products Fail - and How We Fix Them
HeatShield makes a solid product, but every system has weak points, and over two decades on Brentwood rooftops we’ve found where they show up. Here’s what we actually see on service calls:
- HeatShield Cease Fire crown cracking at the flue collar. This is the crown repair we do most often. The crown material pulls away from the clay or steel flue tile as it heats and cools, leaving a gap that lets water run straight down into the firebox. We grind the joint clean, pack it with a flexible sealant rated for high heat, and coat the whole crown so it moves with the temperature swings we get in Brentwood without opening back up.
- Rusted-out caps on HeatShield Eco-Saver systems. The Eco-Saver line was built for affordability, and the factory lids are thinner gauge than the rest of the system. After eight or ten winters, the mesh screens pop loose and the lid starts to pinhole. We replace them with a heavier stainless cap that still fits the existing collar, so you don’t have to touch the liner to fix the top.
- Multi-flue caps that don’t cover the whole crown. On Brentwood capes and colonials near Brentwood State Park, we see a lot of HeatShield setups with two or three flues. If the original install used individual caps instead of a single multi-flue cap, the exposed crown between them turns to dust eventually. We swap in a full-width multi-flue cap that covers the entire crown and sheds water to the drip edge instead of pooling it on top.
- HeatShield Supreme aftermarket parts that don’t seat right. Homeowners sometimes order a cheap universal cap online and wonder why it wobbles. The Supreme line has slightly different flue tile dimensions than generic caps are built for. We either match the cap to the actual tile size or bend the mounting legs so it locks down tight. A cap that rattles in the wind is a cap that’s grinding against your crown.
- Failed caulk seams on pre-fab HeatShield terminations. On factory-built chase tops, the cap body relies on a bead of caulk where the top plate meets the chase cover. Once that bead cracks, water follows the screws down into the framing. We pull the cap, wire-brush the mating surfaces, and reseal with a polyurethane that’s rated for exterior metal and actual temperature swing, not the cheap silicone that was there before.
Our HeatShield Chimney Cap & Crown Process
Here’s how a HeatShield cap and crown job goes when Wendell and his crew show up at a Brentwood home:
- 1
The call. You tell us what the chimney’s doing, or what a previous sweep told you. We give you a straight price range over the phone before anyone gets on a ladder. The number you hear is the number on the invoice.
- 2
The look. We get on the roof and check the crown, the cap, the flue tiles, and the chase or masonry around them. We take pictures of everything, including the inside of the flue if water’s been getting in.
- 3
The plain-English verdict. We show you the camera footage and tell you exactly what needs doing and what doesn’t. If the crown has another year in it, we’ll say so and leave it alone.
- 4
The parts call. For HeatShield systems, we check measurements and match the cap or crown material to the actual system. We use OEM HeatShield parts when they’re warrantable and available, and heavier aftermarket stainless when the factory part was the weak link in the first place.
- 5
The fix. We do the repair or replacement, which usually means removing the old cap, prepping the crown, pouring or coating, and setting the new cap with mechanical fasteners, not just caulk.
- 6
The test and the promise. We check the seal, run water over the top to confirm it sheds, and leave you with the 90-Day Done Right Promise in writing. If anything’s off, one call brings us back at no charge.
What HeatShield Chimney Cap & Crown Costs in Brentwood
Honest numbers, because you shouldn’t have to guess. Cap replacement on a single-flue HeatShield system in Brentwood runs $250 to $450 for standard stainless, and $500 to $850 for a multi-flue or custom-fit cap. Crown sealing and coating runs $400 to $700 if the crown’s still structurally sound. A full crown tear-out and repour with proper concrete and a flexible bond break runs $900 to $1,800 depending on flue count and roof pitch. Chimney height, chase repairs, and masonry patching are what move the price. What doesn’t move it is bait-and-switch pricing. We give the price before work starts and the invoice matches. Call (934) 935-3847 for a free estimate, no trip charge inside the county.

FAQs
No. As an independent HeatShield service provider, we match parts and materials to the original system specification, so warranty coverage on the liner itself is not affected by cap or crown work. If a warrantable HeatShield liner issue shows up while we’re up there, we’ll tell you and point you to the right claim path. Call (934) 935-3847 and we’ll walk you through it.
Yes, as long as the crown hasn’t spalled or separated to the point where it’s structurally gone. We grind the cracked surface, fill the gaps at the flue collars with high-heat flexible sealant, and apply a crown coat that flexes with Brentwood’s freeze-thaw cycles. If the crown is crumbling in chunks, a repour is the only fix that lasts, and we’ll show you why with photos before we touch it.
Most Brentwood calls get scheduled within a few days, and a standard cap replacement is a single-visit job. If water’s pouring in and you need it sooner, tell the person on the phone. We keep common stainless cap sizes on the truck, and if we have the right one, we can usually handle it the day we’re out. Free estimates: (934) 935-3847.
Once a year, burn or no burn. Chimneys break in the off-season too. The cap is the first thing to go because it takes full sun, rain, and whatever Brentwood’s weather throws at it, and by the time you see rust or a missing screen from the yard, water’s usually been finding its way in for a while. We’ll take a look and tell you if it’s fine. If it is, we’ll say so and leave.
Both, and we’ll tell you which we’re using and why. Genuine HeatShield caps go on when the system’s under active warranty coverage and the part is built well. When the factory lid was the weak point, we use heavier aftermarket stainless that fits the exact flue dimensions of your system. Either way, the cap is matched to the actual measurements, not forced on with a universal adapter kit.
