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.
Fast, Reliable Chimney Cap & Crown Across Avon
A chimney cap and crown in Avon usually runs $220-$680 for standard work, with multi-flue caps and custom directional caps landing between $450 and $1,100 depending on flue count and wind exposure. Most jobs are done in one visit. Wendell Pike has been looking at Avon chimney tops since 1999, and he’ll give you a straight number before any tool comes off the truck. Call (860) 743-7743 and a live person answers, day or night.
We work the neighborhoods along Route 44, up Avon Mountain Road, and through the Farmington Valley corridors every week. These aren’t simple single-flue ranches. They’re large colonials and capes with two or three fireplaces, mixed masonry and prefab chases, and crowns that take a beating from Talcott Mountain weather. Our Avon Fireplace Services cover every configuration we see. We know what we’re looking at before we climb the ladder, and that saves you money.
Why Top Hat Chimney Is Avon’s Preferred Chimney Cap & Crown Company
We’re the local outfit that puts a name on the work. Wendell Pike founded Chimney Cap & Crown in Avon work on simple terms: publish the license number, show up in uniform, hand you a written price before the ladder comes off the truck, and back the whole thing with a 90-Day Done Right Promise. If it’s not right, one call brings the crew back at no charge.
Ask anyone on your street. Homeowners in Avon have been burned by national franchises that send a stranger with a tablet full of add-ons and a price that changes at the door. Wendell has run into the same Avon customers at the hardware store for over 25 years. That changes how you quote a job and how you finish one. Every technician is background-checked and gives you a real arrival window. Calls are answered by a live person 24/7, and half the time it’s Wendell himself.
Avon’s housing stock works in our favor and yours. The homes built between 1975 and 2000 along Route 44 and the Farmington Valley corridors were built for families who wanted multiple hearths. That means we see the same cap and crown failure patterns on house after house, and we’ve learned exactly which fixes hold up on this terrain. No trial and error. Just the right repair the first time.
Our Chimney Cap & Crown Services in Avon
This is the page for everything that sits on top of your chimney and keeps water, wind, and animals out. Here’s what we do in Avon, and how it applies to the homes we see here.
Cap Installation
A proper cap keeps rain out of the flue and keeps the local wildlife on the ground. In Avon, that means raccoons looking for a den and squirrels with a ladder problem. We install standard single-flue caps, custom sizes for oddball tile liners, and the heavier Copperfield caps that hold up to the wind off Talcott Mountain.

Cap Replacement
Rusted, missing, or undersized caps are the most common thing we find during our Chimney Cleaning & Sweep in Avon. If your cap is rusting through, it’s already letting water into the flue or the chase. We pull the old one, measure the flue exactly, and replace it with a cap that fits the liner, not just the outside tile. On Avon Mountain Road and the upper ridgeline subdivisions, we routinely replace standard round caps with directional models because the northeast wind load will reverse standard caps every season.

Crown Repair
The concrete crown is the flat slab that seals the top of the chimney. In Avon’s wet, freezing winters, water gets into hairline cracks, freezes, expands, and pops chunks of concrete loose. That’s spalling, and once it starts it accelerates. We repair crowns with proper crown cement, not mortar, and only after the surface is cleaned and prepped, as part of our Chimney Repair in Avon. On multiple-flue masonry chimneys, which are common on Avon’s 1970s and 1980s colonials, crown repair often means rebuilding the entire top slab to get a proper overhang.

Crown Coating
Coating is what we do before the crown needs a full rebuild. We apply Gelco crown coating to seal hairline cracks and prevent the freeze-thaw cycle from doing real structural damage. In Avon, where the burn season runs October through April, a coated crown is the difference between a five-year crown and a twenty-year crown. If we can coat it early, you don’t pay for a rebuild later.

Multi-Flue Cap
This is a big one in Avon. Many colonials here have two or three flues terminating side by side on a single masonry chimney, or a masonry chimney next to a prefab chase. A single multi-flue cap spans all the terminations and seals the entire top. It’s cleaner than separate caps, drains better, and gives you one piece of metal instead of three. We measure on site and order the cap to the exact flue spacing. This is not a one-size-fits-all job.

Custom Cap
Some chimneys in Avon don’t fit anything off the shelf. Oversized flues on older farmhouse chimneys, odd tile configurations, decorative caps on architectural chimneys. We fabricate custom caps to spec and install them to hold up to the same wind loads as everything else on the ridgeline. If you want something that looks right on a $900,000 colonial, we’ll build it that way.

Trusted Brands We Service in Avon
We install and service caps, crowns, and related components from Chimney Cap & Crown suppliers we trust: Copperfield, DuraFlex, Gelco, and Famco. These are the brands that hold up to New England weather, and we keep common sizes and parts on the truck for Avon calls. That means fewer second trips and no waiting two weeks for a part that should have been in stock. When a customer off Avon Mountain Road needs a directional cap before the next weather front, we usually have it with us.
One more thing worth knowing: we’re not a franchise rotating crews in from another county. Scheduling is coordinated from the Hartford metro office, and the crews that show up in Avon are the same people who’ve been working these streets for years. Same faces, same standards, same promise in writing.
Common Chimney Cap & Crown Problems We See in Avon Homes
- Wind-driven smoke-back on Talcott Mountain slopes. Homes on the western and northern sides of Avon sit in a prevailing wind channel that pushes smoke down the flue. Standard round caps can’t fight it. Directional and draft-inducing caps usually can, and we know which ones work because we’ve tested them on the worst ridgeline exposures in town.
- Spalled crowns on multi-flue masonry chimneys. Avon’s freeze-thaw winters are hard on concrete crowns, especially wide crowns spanning three flues. Once water gets in and freezes, the surface starts pitting, then chunks break off. The water then drops into the flue liners and smoke chamber, which is a much more expensive repair than the crown itself.
- Failed caps over aging zero-clearance fireplaces. The prefab fireplaces in Avon’s 1975-1999 colonials are now 30 to 50 years old. A missing or rusted cap lets rain fall directly onto the metal firebox and liner panels. We see the rust-water streaks on the chase every time. A $300 cap today prevents a $3,000 liner job in two years.
- Improperly sized caps on replacement flues. When a previous contractor relined a flue or converted a fireplace to gas, the old cap often doesn’t match the new liner size. That gap lets rain and animals in around the edges. We re-measure and refit so the cap actually seals the flue, not just the tile around it.

- Aging prefab fireplaces in 30-50-year-old Avon homes need caps and coatings before water destroys the firebox.
- Fixed upfront pricing, 90-Day Done Right Promise in writing, and a live person on the phone 24/7.

FAQs - Chimney Cap & Crown in Avon
If your home sits on the western or northern slope of Talcott Mountain or along Avon Mountain Road, yes, you’re at higher risk for wind-driven downdraft, and a directional cap is usually cheaper than chasing the problem after you’ve already had smoke in the living room. The wind patterns here are consistent, not occasional. We recommend directional caps on those exposures before you see smoke-back because once the smoke starts reversing, you’ve already had a night or two of particulate blown back through the firebox. Call (860) 743-7743 and we’ll take a look at your specific roofline and flue configuration before you commit to anything.
Yes, if the flues terminate side by side on the same masonry chimney or the same chase, a multi-flue cap can cover all of them in one unit. If the flues are on separate chimneys or chases, you’ll need two or three separate caps. The multi-flue cap approach is cleaner and often more durable in Avon’s climate because it eliminates the gaps between individual caps where water and animals work their way in. Call (860) 743-7743 for a measurement visit, and we’ll tell you which option actually fits your house, not which one we’d rather sell.
Because what looks fine from the ground is exactly what fails first on Avon’s aging zero-clearance fireplaces. The crown on a prefab chase is often just a metal pan with a thin sealant coating, and 35 years of Farmington Valley rain and freeze-thaw cycles have likely started the rust process you can’t see. A missing or failed cap lets rain fall directly onto the metal firebox and liner panels, which are already past their rated service life. A cap and Gelco coating now is a $400-$700 job. A firebox replacement is several thousand. Call (860) 743-7743 and I’ll show you the camera footage, so you can see the rust before you spend a dollar.
When you see small concrete chips or sand-like grit at the base of the chimney or in the gutters, the freeze-thaw cycle has already started breaking the crown apart. The next stage is visible cracks wide enough to fit a nickel, and after that, chunks start falling. In Avon, the wet months from November through March are when most of the damage happens, because that’s when water sits in the cracks and freezes overnight. If you see grit, call us before the first hard freeze. Call (860) 743-7743 for a crown inspection, and we’ll give you a fixed quote for either a coating or a rebuild, whichever is actually needed.
Yes, and here’s the reason: a gas insert still exhausts through the flue, and the cap you had sized for a wood fireplace may not match the new liner diameter or the draft characteristics of the gas appliance. In Avon, where many of those Route 44 colonials are converting from wood to gas, we regularly replace the old round cap as part of the conversion. It seals the top correctly, keeps rain off the new liner, and prevents the kind of draft issues that gas appliances are sensitive to. Call (860) 743-7743 and we’ll quote the cap replacement along with the rest of the conversion, so there’s one number upfront and no second visit.
