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.

How HeatShield Products Fail - and How We Find It Early
HeatShield builds a solid product, but every liner system has weak points. Here’s what we see in Coventry homes, season after season.
- HeatShield 314L Stainless Reline Kits: The lightweight 314L alloy holds up well against flue gases, but the thin-wall construction doesn’t love being scrubbed with aggressive wire brushes. We’ve seen crews from other companies go at these liners with brushes meant for masonry flues and leave fine scoring behind. Scoring gives creosote a foothold. Wendell’s crew uses poly brushes on all HeatShield stainless work. It’s a small thing, but it keeps the liner smooth and the creosote from grabbing hold.
- HeatShield GyFloam Sealant Deterioration: When HeatShield resurfacing compound ages, it doesn’t crack the way you’d expect. It starts turning soft and crumbly near the top of the flue, where temperature swings in a Coventry winter are most violent. During a sweep, we’ll see a fine sandy grit falling out of the upper tile joints. That’s the GyFloam breaking down. If we catch it early, it’s a localized patch. If we don’t, it’s a reline.
- HeatShield TherMax Panels in Older Fireboxes: The TherMax refractory panels hold up, but the panel clips and retaining brackets loosen over time. A loose panel rattles, and it also lets heat reach the firebox wall behind it. Homeowners rarely notice until they hear the rattle. When we’re in there for a sweep, we check every clip. Takes five minutes. Saves you from a warped firebox.
- Creosote Bonding at the Liner Seams: HeatShield’s interlocking segments are not the problem. The problem is the seam where the connector collar meets the existing clay tile. Third-degree glazed creosote loves to form at that transition, because it’s a spot where draft slows down just enough for smoke to linger. In Coventry homes that burn a lot of unseasoned oak, this seam loads up fast. We pay extra attention to it on every HeatShield sweep.
- Improperly Installed HeatShield Top Plates: We didn’t install every HeatShield system in Tolland County, and some of the ones we didn’t install have top plates that were never sealed correctly. Water gets under the plate, runs down the outside of the liner, and the first sign is usually rust staining on the damper hardware. By the time you see water in the firebox, the liner’s outer surface has been sitting wet for a while. A sweep catches this early if the sweep looks for it. We do.
Here’s the thing about HeatShield failures: most of them announce themselves as a change in how the chimney behaves, not as a sudden breakdown. Smoke that rolls into the room when you first light a fire. A smell you didn’t have last season. A fine grit collecting on the smoke shelf. Your flue doesn’t care how the fire looks. It cares how it breathes.
Our HeatShield Chimney Cleaning & Sweep Process
- 1
You call, a person answers. Around the clock, and it may well be Wendell himself picking up. You tell us what you’ve got in Coventry, we give you a straight price range before anything is scheduled.
- 2
We arrive and protect the space. Drop cloths, shoe covers, and a real arrival window that we actually hit. Then we lay eyes on your HeatShield system before a single tool comes off the truck.
- 3
Camera inspection first. Every HeatShield chimney gets a camera run before the sweep starts. We’re looking at seam integrity, GyFloam condition, panel fit, and creosote load. You’ll see the footage.
- 4
The sweep itself. Poly brushes on HeatShield stainless. Air-driven whip for glazed sections. The goal is clean, not scratched. We’re careful with your liner the way we’d be careful with ours.
- 5
Plain-English verdict. Camera footage after the sweep. If it’s clean and sound, we tell you. If it needs work, we show you exactly what we saw and tell you honestly whether it can wait. If it doesn’t need doing, Wendell will tell you.
- 6
Cleanup and the promise. The fireplace looks better than when we arrived. And every job carries the 90-Day Done Right Promise in writing: if it’s not right, one call brings us back.

FAQs
No. Regular chimney cleaning and sweeping is required maintenance for every liner manufacturer, including HeatShield, and using an independent HeatShield service provider does not void your warranty. What voids warranties is neglect and damage from improper cleaning methods. We use poly brushes on HeatShield stainless specifically to protect your liner. Call (860) 743-7732 if you want to talk through what your warranty actually covers.
Once a year, burn or no burn. Chimneys break in the off-season too. Coventry winters mean you’re burning hard from October to April, and that’s when creosote builds up. But summer humidity in Connecticut can attack GyFloam joints just as surely as fire can. An annual sweep catches both kinds of problems. If you burn green wood or burn more than three cords a season, you may need two sweeps a year. We’ll tell you honestly after your first visit.
When HeatShield OEM parts are available and make sense, we use them. When an OEM part is backordered or overpriced for what it is, we’ll tell you that too, and we’ll recommend a proven aftermarket alternative from brands we trust. You’ll always see the receipt for what we installed, and we’ll never mark something up without telling you what the part actually cost.
Yes, but it takes longer and costs more due to the creosote load. First-degree creosote is a brush job. Third-degree is a glaze. If a liner has been neglected for five or more years, we’ll camera it first to check for damage underneath, then quote you honestly. Some liners are salvageable. Some are not. If yours isn’t, Wendell will tell you before any money changes hands.
Creosote keeps building. In a HeatShield stainless liner, heavy creosote doesn’t just create fire risk, it traps moisture against the liner walls and accelerates corrosion at the seams. First-degree creosote is a brush job. Third-degree is a glaze. Catch it early. The camera footage and a plain-English verdict come with every sweep we do, so you’ll always know where you stand. Call (860) 743-7732 to book your sweep before the burn season gets here.
