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 Coventry: What to Know First
We provide independent HeatShield chimney cap and crown repair in Coventry, with most jobs completed in a single visit once we’ve seen the damage. A cap replacement on a HeatShield-lined flue typically runs $180-$450 in this area, while crown work usually lands between $350-$900 depending on how far the deterioration has spread. We don’t charge a trip fee inside Tolland County, and we’ll give you a firm price before any tool comes off the truck.
If you own a HeatShield system and you’re seeing water in the firebox, spalling brick near the top of the chimney, or a cap that’s rusted through, this page will tell you what’s actually going on and what it costs to make it right. Call (860) 743-7732 and you’ll get a live person – often Wendell Pike himself – not a voicemail box.
Key Takeaways
- HeatShield is a flue liner and repair system, not a cap or crown product – but the materials used around it matter where they meet.
- We’re an independent HeatShield service provider. We install and service their liners, but we are not owned by or authorized by the manufacturer.
- Most cap failures on HeatShield chimneys in Coventry trace back to water getting behind the crown, not to the liner itself.
- We stock common cap sizes and can custom-fabricate within a week. Crown coating resin is jobsite-mixed, so no waiting on parts.
How HeatShield Products Fail - and How We Fix Them
HeatShield builds its reputation on the Cerfractory flue sealant system, and it’s a good product. But the cap and crown are the first line of defense, and when they go, they take the HeatShield liner down with them. Here’s what we actually see on HeatShield-equipped chimneys around Coventry:
- Rust-through on OEM caps above HeatShield liners. Many Coventry homes had their HeatShield liner installed in the early 2000s with a standard galvanized cap. Galvanized steel lasts 8-12 years in New England weather. By year 10, the lid is Swiss cheese and water pours straight down the flue. We replace with stainless steel, which gives you 20+ years, and the price difference is usually under $100.
- Crown cracking where the clay flue tile was sealed over. The HeatShield Cerfractory liner goes inside the existing flue, so most Coventry installs kept the original clay tile at the top. The crown was poured around that tile decades ago. Freeze-thaw cycles along Route 31 and out toward the lake country pop the bond between crown and tile. Once that hairline opens, water follows the HeatShield seam downward. We saw three of these in one week last spring, all on chimneys built between 1978 and 1985.
- Spalling at the crown edge on single-flue HeatShield systems. The crown should overhang the brick by at least two inches. On some of the older Coventry builds, the original mason poured the crown flush with the brick face. HeatShield can’t fix that, and neither can a cap. The crown edge starts crumbling within a few seasons. We rebuild the crown with a proper drip edge and coat it before it takes the top course of brick with it.
- Improperly sized caps installed after a HeatShield liner job. Here’s one you won’t read on HeatShield’s site. When a liner is dropped in, the flue opening changes. Some installers, especially the franchise operations that blow through town, slap on whatever cap they have in the truck. If the cap’s mesh screen hangs over the liner edge, condensation collects there and drips back down. We measure the actual liner diameter, not the old tile, and fit the cap to the HeatShield system as it sits now.
- Multi-flue cap installations that trap heat. HeatShield liners are insulated in many Coventry installations. On a wide-mouth chimney with two flues, a single multi-flue cap can trap warmer air between the liner tops. That’s not a fire hazard if the liners are properly installed, but it does accelerate rust on the underside of the cap. We prefer individual caps per flue unless the homeowner specifically wants the multi-flue look, and we’ll tell you why.
Our HeatShield Chimney Cap & Crown Process
Here’s how a HeatShield cap and crown job goes with us, from the first phone call to the last brush stroke:
- 1
You call or fill out the form. A live person answers. We ask what you’re seeing – water in the firebox, rust flakes on the hearth, visible cracks up top. We set a real arrival window and we call if anything slips.
- 2
We inspect from top and bottom. Wendell or one of his crew goes on the roof and photographs the cap, crown, and top of the flue liner. Meanwhile, someone checks the firebox for water stains. On HeatShield systems, we also run a camera to confirm the Cerfractory seal hasn’t delaminated from the tile wall.
- 3
You get a verdict with evidence. We will show you the pictures and the camera footage, then tell you in plain English what is urgent, what can wait, and what does not need doing. If the cap is fine and the crown has another year, we will say so. If it doesn’t need doing, I’ll tell you.
- 4
We agree on a fixed price. The number you agree to is the number on the invoice. We source OEM HeatShield-compatible components where it matters, and we will use quality aftermarket stainless caps where the OEM part is just a rebranded galvanized unit with a markup.
- 5
The repair gets done same-day where possible. Cap replacements are typically a one-visit job. Crown rebuilds with a proper concrete pour need about 24 hours of cure time before coating, so those run two visits over two days when weather allows.
- 6
We test it and back it. We water-test the crown seal where practical and confirm proper cap seating before we leave. Every HeatShield cap and crown job carries our 90-Day Done Right Promise in writing. One call brings us back, no charge, no argument.
We also work with DuraFlex and Gelco systems, so if your chimney has mixed components from prior owners, we are not the crew standing on your roof scratching our heads. We have seen just about every combination Coventry has thrown at us since 1999.
What HeatShield Chimney Cap & Crown Costs in Coventry
Here are real numbers for HeatShield chimney cap and crown work in the Coventry market, based on what we have charged over the past year:
- Standard single-flue stainless cap replacement: $180-$320 installed, depending on flue diameter and roof access difficulty.
- Custom-sized cap for an oval or oversized HeatShield flue: $280-$450, including fabrication if a stock cap will not fit.
- Multi-flue cap for HeatShield chimneys: $350-$750, depending on span and material gauge. We’ll quote individual caps against it so you can compare honestly.
- Crown repair (minor crack sealing, no major spall): $350-$550, including cleaning, bonding, and a waterproof membrane coat.
- Crown rebuild with proper overhang and drip edge: $650-$900 when the old crown is too far gone to patch. This includes form work, new concrete, and a full crown coating.
- HeatShield Cerfractory touch-up at the flue-to-crown junction: $150-$250 when we find the liner seam has started to open. We only recommend this when the camera shows localized wear; we’ll never sell you a full reline for a seam problem.
What moves the price: roof pitch and chimney height, whether the old crown was poured correctly in the first place, and whether we have to remove a rusted-on cap with a grinder. Call (860) 743-7732 for an exact quote after the inspection – estimates are free, and we do not charge a trip fee inside the county.

FAQs
Replacing a cap or repairing a crown does not void a HeatShield liner warranty, provided the work doesn’t disturb the liner itself. HeatShield’s warranty covers the Cerfractory sealant and repair materials, not the cap, crown, or masonry. We document every job with photos so you have a record if a warranty question ever comes up. Call (860) 743-7732 and we’ll walk you through what your specific warranty covers before we touch anything.
Yes. The liner materials are still widely available to independent contractors, and the caps and crowns were never HeatShield-branded parts to begin with – they’re standard chimney components sized to the flue. If your old cap was a custom oval or odd-size piece, we can fabricate a replacement in about a week at our shop. The liner itself rarely needs parts unless it’s physically damaged.
Water in the firebox after rain, rust stains running down the brick below the crown, and chunks of mortar on the roof or ground are the three reliable signs. But the only way to know for sure is a camera inspection and a look from the roof. We’ll show you exactly what we find, and we’ll tell you if the cap is fine and the water is coming from somewhere else. We do not guess and we do not upsell.
Most cap and crown inspections inside Tolland County get scheduled within the week, and we’ll often have you on the calendar within a few days during the spring and summer. Crown rebuilds are weather-dependent, so we schedule those for a stretch of dry days. If it’s urgent – water actively entering the home – tell us when you call and we’ll do what we can to move you up. The number is (860) 743-7732.
That depends entirely on what the inspection shows. A cracked crown will keep letting water into the brick and eventually the liner, no matter how good the new cap is. A rusted cap lets water pour straight down the flue, no matter how good the crown is. We’ll show you the damage and give you an honest recommendation. If the crown has another year in it, we’ll say so and you can plan for it.
Ready to get eyes on your chimney? Call (860) 743-7732 for a free estimate. A live person answers, the number you hear is the number you’ll pay, and if the work isn’t done right, one call brings us back. That’s been the deal since 1999.
