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 Windsor
A chimney cap and crown replacement in Windsor typically runs $340-$890 for the crown, $180-$520 for a standard cap, and $680-$1,400 when both need work on a two-flue chimney. Most jobs in Windsor are done in one visit once we’ve confirmed the flue dimensions with a camera. If water is getting into your firebox or you’ve found rust flakes on the hearth, call (980) 580-8641 and we’ll give you a written price before any work starts.
Windsor isn’t like the newer subdivisions in South Windsor or Farmington. Along Palisado Avenue and the town green, we’re working on chimneys that were built before the United States existed. That changes how a cap or crown job gets quoted, and it’s why we never size a cap from the ground or assume a standard flue tile fits. We document everything with a camera and show you what we found.
Why Emberly Chimney Cleaners Is the Chimney Cap & Crown Team Windsor Calls
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and the Windsor ones stand out. The town’s oldest housing stock predates standardized flue tile by a century, so a chimney on Palisado Avenue almost never has uniform interior dimensions. Corrine Halstead, who leads our team, made camera-scan documentation standard practice in 2009 under what became Clause 4 of the Haven Standard. That means every Windsor job, whether it’s a simple cap replacement or a crown rebuild, gets a photo record before and after.
Our crews know the difference between a colonial-era three-flue chimney with a shared crown and a mid-century ranch on Bloomfield Avenue with a single undersized oil flue. That knowledge changes what we recommend. When a Windsor homeowner asks for a cap, we don’t just bolt one on. We figure out whether the crown underneath will hold it, whether the flue is sized for the appliance it actually vents, and whether an adjacent unused flue is open to weather and animals. You get a written scope, a written warranty, and photos of everything we saw. That’s how we’ve earned a strong reputation in Windsor.
Calls from Windsor are answered by a live person, any hour. Scheduling is coordinated from our Hartford office, and crews serve Windsor daily. You’ll get a text when your technician is on the way, with their name and license information.
Our Chimney Cap & Crown Services in Windsor
Cap Installation
A new chimney cap in Windsor runs $180-$520 depending on the flue count and whether the crown needs prep work first. We install multi-flue and custom caps, including Copperfield units, and we size them from camera measurements, not from a guess at the roofline. On older Windsor chimneys with irregular handmade-brick flue openings, a standard cap often won’t seat properly. That’s when we go custom.
Cap Replacement
Rusted or missing caps are common in Windsor because the river confluence keeps ambient moisture high. A replacement cap job usually runs $220-$480 for removal, disposal, and installation. We also check the crown at the same time. If the old cap’s mounting flange has rusted through, there’s a good chance the crown underneath has cracks that were letting water sit against the flue tile.
Crown Repair
Crown repair in Windsor typically costs $340-$890. That range covers everything from minor crack repair and sealing on a simple single-flue crown to rebuilding a wide multi-flue crown on a colonial. We use Gelco crown coating on most Windsor crowns because it bridges small cracks and gives a flexible, weatherproof surface that holds up through Connecticut freeze-thaw cycles. The river climate here punishes rigid mortar crowns faster than drier inland towns.
Crown Coating
A crown coating over an intact but weathered crown runs $290-$640 in Windsor. It’s the most cost-effective way to add years to an older crown that hasn’t cracked through yet. We clean the crown, repair any missing mortar joints, then apply two coats of Gelco. We document the before and after with photos. This is a standard part of our Chimney Cap & Crown service across Connecticut, and in Windsor it’s especially important because the freeze-thaw cycle at the Farmington River floodplain accelerates spalling.

We install and service caps and crowns from Copperfield, DuraFlex, and Gelco. Copperfield caps hold up well on multi-flue colonial chimneys where standard sizes won’t fit. DuraFlex liners come into play when a crown repair reveals a damaged flue that also needs addressing. Gelco crown coating is our default surface treatment because it flexes through Windsor’s winter temperature swings. Parts are ordered through our supply network and arrive fast, which keeps most Windsor cap and crown jobs on a single-visit schedule.
Common Chimney Cap & Crown Problems We See in Windsor Homes
- Freeze-thaw crown cracking near the river confluence. Windsor’s location at the Connecticut and Farmington Rivers means higher ambient moisture. When that moisture soaks into a crown with even a hairline crack, winter freezes expand it, and by spring the crack is wide enough for water to run down the flue tile and into the firebox.
- Rusted cap flanges on older multi-flue chimneys. Along Palisado Avenue, we regularly find caps that were installed for one fuel era and left in place through three more. Rain and nesting animals get in through the unused flue and damage the smoke chamber below.
- Condensation damage on mid-century chimneys. Capes and ranches along Bloomfield Avenue often have original oil-heat flues that were never relined when owners added gas inserts. A cap on an undersized liner traps condensation, which accelerates liner deterioration and shows up as rust stains on the firebox floor.
- Spalling brick at the crown line. The oldest Windsor chimneys used lime-based mortar. Once that mortar loses its bond, bricks begin flaking off at the top. A new cap won’t stay anchored to a spalling crown, so the crown has to be repaired first.

A 1790s colonial with three flues, a shared crown, and mismatched terra-cotta patch sections is a different job entirely. You get a written price before any work starts, and it includes the scope, the materials, and the warranty. No surprises after the fact.

FAQs - Chimney Cap & Crown in Windsor
Because those chimneys have been modified across three or four fuel eras, and what’s inside the flue rarely matches what you see from the ground. A colonial that started as a wood-burning hearth often has a coal insert, an oil boiler flue, and a gas appliance stacked inside the same stack. Standard cap sizing won’t work, and quoting without camera evidence means guessing. We send a camera down every flue on every Windsor job, then show you the footage. Call (980) 580-8641 and we’ll schedule it.
It accelerates crown deterioration. The river confluence means higher year-round ambient moisture, which soaks into even hairline cracks. Each winter freeze expands that water, and each thaw lets it push deeper. Windsor crowns spall and crack faster than chimneys in drier inland towns. Annual inspection catches this before the crown fails completely.
No, and that’s an important distinction. A cap keeps out rain, animals, and debris. It does not reduce creosote buildup. Third-degree creosote is a tar-like glaze that forms inside the flue from incomplete combustion, usually in unlined or oversized chimneys common in older Windsor homes. A cap is still worth installing, but it’s not a substitute for cleaning and a camera inspection. If you’re unsure what’s inside your flue, call (980) 580-8641 for a written assessment.
A flexible coating like Gelco is the right choice. Those old crowns were built with lime-based mortar, which is porous and brittle. A rigid Portland-based patch will crack again within a season or two because the brick expands and contracts through Windsor’s temperature swings. Gelco flexes slightly, which is what an old crown needs. We apply it after repairing missing mortar joints and document the finished surface with photos.
Because the original flue was sized for an oil furnace, not a wood stove. Many of those capes and ranches still have an undersized or unlined flue from the original oil-heat installation. A wood stove vented into that flue creates a creosote risk and a draft problem. Before you install a stove, we need to camera the flue, check the existing cap, and determine whether a liner is required. We’ll show you the footage and give you a written price for whatever the chimney needs.
