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.

AfterFast, Reliable Chimney Cap & Crown Across Collinsville
Chimney cap and crown work in Collinsville usually comes down to two things: keeping water out and keeping embers in. A cracked crown or a missing cap on a 150-year-old flue is not a cosmetic problem here. It’s how a $400 repair becomes a $9,000 liner replacement. We’re Top Hat Chimney, Wendell Pike’s crew, and we’ve been working the Farmington Valley long enough to know exactly what Collinsville’s wind and freeze-thaw cycles do to mortar and metal. Call (860) 744-2656 and you’ll get a straight answer, not a sales pitch.
Why Top Hat Chimney Is Collinsville’s Preferred Chimney Cap & Crown Company
We’re not a franchise that rotated in last spring. Wendell founded the company in 1999 and his name goes on every job. Collinsville homeowners tell us the same thing: they’ve been burned by a national outfit that quoted one number on the phone and a different one at the door. We give upfront pricing before a single tool comes off the truck. The number you hear is the number on the invoice.
Our crew knows the Collinsville Historic District, Cherry Park, and the Canton Center Historic District. We know what an original 1840s chimney looks like from the inside. And every job, including Chimney Cap & Crown work, carries the 90-Day Done Right Promise in writing. If it’s not done right, one call brings Wendell back. For Chimney Cap & Crown in Collinsville, that promise means something. You’ll see us again on Saturday, not just when the invoice is open.
Our Chimney Cap & Crown Services in Collinsville
Cap Installation
New caps on Collinsville chimneys are not one-size-fits-all. The historic rowhouses along East Main Street and the mill-worker cottages near the Collins Axe Factory have flues that predate modern sizing standards by a century. We measure the actual flue tile, not the outside brick. A stock cap from a box store leaves gaps that wind-driven rain will find. We install caps sized to the clay tile opening, with screening fine enough to keep embers and birds out but open enough to preserve draft on Avon Mountain Road.
Cap Replacement
Wind-driven rain funnels into uncapped or damaged flues in the Farmington River valley. We see caps that have been lifted by cold air drainage inversions, bent legs, torn screens, rusted bases. Replacing a cap in Collinsville means matching the existing flue geometry and checking for hidden damage below. A cap that’s been off for one winter has already let water into a rubble-mortar flue. We check what the cap was protecting, not just what the cap looked like.
Crown Repair
This is the most common call we get from Collinsville homeowners, and it’s almost always a crown, not a cap. Hard winter burns in unlined flues accelerate crown spalling. Thermal cycling from a 600-degree flue gas hitting a 15-degree crown cracks the mortar in a season or two. We rebuild crowns with a proper Portland-based mix, then coat them with a weatherproof sealant. A crown that sheds water is a flue that doesn’t soak it up.
Crown Coating
For crowns that are still structurally sound but starting to show hairline cracks, a crown coat is the difference between a $350 fix now and a full crown rebuild later. We use DuraFlex crown coat and similar products, applied over a cleaned and prepped surface. In Collinsville’s freeze-thaw cycle, a sealed crown is the only crown that lasts. Water gets into a hairline crack, freezes, expands, and turns the crack into a chunk.

Common Chimney Cap & Crown Problems We See in Collinsville Homes
- Storm-driven water intrusion in shared-wall flues. Collinsville’s mill-era rowhouses along East Main Street and Waterville Road share party walls with closely adjacent flue systems. A cracked crown on one unit channels water into a neighbor’s masonry, and the ceiling stain shows up next door, not in the unit with the bad crown.
- Cap uplift from valley wind patterns. The Farmington River valley creates cold air drainage that produces temperature inversions in winter. Wind gusts funnel along Avon Mountain Road and hit chimneys from odd angles. We regularly find caps lifted off their bases with legs bent, screens torn loose, and embers on shared roofs.
- Spalled crowns from unlined flue heat. Original flues in pre-Civil War homes have no clay tile liner. The flue gases run hotter against the masonry, and the crown takes the brunt. Thermal cycling over one hard burning season can spall chunks off the crown edge, which then damage raincaps below.
- Water pooling on flat crowns on 1850s chimneys. The Federal and Greek Revival homes in the Canton Center Historic District often have wide, nearly flat crowns built for a different chimney design. Water pools, soaks into the mortar, and freezes. We slope the crown surface during a rebuild to shed water, which no original 1850s mason ever did.

FAQs - Chimney Cap & Crown in Collinsville
You’ll see it first as a ceiling stain or damp smell on the party wall, usually a few feet from the chimney chase. In Collinsville’s rowhouses along East Main Street, the flues run side by side inside a shared masonry mass, and water entering one crown can travel down the common mortar joints. The sign is a stain that appears after heavy wind-driven rain, not after a normal rain. If your neighbor has a stain and your crown has visible cracks, it’s leaking. Call (860) 744-2656 and we’ll camera the flue and give you a plain-English verdict, free estimate included.
For Collinsville, we install caps with a full-coverage lid that extends past the flue tile edge by at least an inch on all sides, screened sides, and legs that set fully inside the flue tile, not clamped to the outside brick. Clamp-on caps fail first in valley wind. The full-coverage lid sheds wind-driven rain from any direction, and the screened sides keep embers from lifting out onto shared roofs. For rowhouses, we use custom galvanized caps from Copperfield sized to the actual tile opening.
Yes, if the crack is through the crown and into the flue masonry, but the flue fire risk is not what most Collinsville homeowners should worry about first. A serious crack lets combustion gases and heat reach the framing around the chimney chase, and that can smolder and ignite even when the damper is closed. The more common and faster problem is carbon monoxide leaking into the house through cracked flue masonry. If you have a cracked crown, don’t wait for the next burn. Call (860) 744-2656.
Because the flue tiles in pre-Civil War rowhouses are not a standard modern size. The rowhouses near the Collins Axe Factory were built with brick flues that were parged on the inside, not lined with clay tile. Stock caps from box stores fit a 13×13 or 8×13 tile. Your 1840s flue might be 11×7 or an irregular round shape. A stock cap leaves gaps, and gaps are where water and embers get through. We measure the actual opening and build the cap to fit it.
You slope it. Original crowns on 1850s chimneys were built nearly flat, and they pond water after every storm. When we rebuild a crown in Collinsville, we form the mortar so the surface slopes away from the flue tile at a minimum pitch, so water runs to the drip edge instead of sitting on the crown. Then we coat it. The slope is the fix. Without it, any coating just keeps water pooled on top.
