Fast, Reliable Chimney Cap & Crown Across Farmington
A chimney cap and crown repair in Farmington typically runs $280-$650 for standard work, with most jobs completed in a single visit. Our technicians cover the full 06030, 06032, and 06034 ZIP codes, including same-day response when water is actively entering the flue.
We’ve been driving Route 10 and Farmington Avenue for over 42 years, and we’ve learned that Farmington chimneys age differently than those in Hartford or Newington. The valley humidity off the Farmington River, the freeze-thaw cycles of Connecticut winters, and the sheer concentration of 18th- and 19th-century masonry in the Main Street historic district all mean that crown deterioration here often hides behind intact-looking brick until the damage is substantial. When you call (844) 803-1545, a live person answers, day or night. We’ll schedule your free estimate, show up when we say, and explain what we’re seeing in plain English, with photos you can view yourself.
Why Hearthstone Chimney Co. Is Farmington’s Preferred Chimney Cap & Crown Company
Farmington homeowners don’t call us because we’re the cheapest option between Hartford and the Farmington Valley. They call because their neighbor on Mountain Road did, or because their contractor on Unionville’s Lovely Street mentioned our name after seeing our work on a colonial-era multi-flue stack. We’ve earned that reputation one crown at a time, documenting every inspection with Level-2 camera footage and a written verdict that a 75-year-old homeowner can understand without a dictionary.
Our response time to Farmington averages under 90 minutes for urgent water-intrusion calls, and we schedule routine estimates within 48 hours throughout the historic district, Unionville, and the executive home corridors near the I-84 interchange. Our technicians are background-checked, uniformed, and carry the professional-grade materials to complete most cap and crown jobs in a single visit, no return trip required.
The 90-Day Done Right Promise governs every job we do in Farmington: if it’s not right, we come back, in writing, no arguing. That’s been our standard since 1984, and it’s why families on Main Street who hired us in the 1990s are now calling for their children’s homes.
Our Chimney Cap & Crown Services in Farmington
Cap Installation
New cap installation in Farmington runs $320-$580 for standard single-flue stainless steel units, with multi-flue caps on historic colonial chimneys ranging $480-$890. The 18th- and early-19th-century homes along the Route 10 corridor frequently have oversized or irregular flue openings that require custom fabrication, something our Chimney Cap & Crown team handles regularly. We measure on-site, fabricate to spec, and install with proper clearance and screening to keep squirrels, raccoons, and the heavy wet leaves of Farmington’s oak-and-maple canopy out of your flue.
Cap Replacement
Replacing a failed cap in Farmington costs $280-$520, depending on whether the flue tile and wash beneath it are still sound. The valley humidity here rusts out galvanized caps faster than in drier hill towns, and we’ve replaced plenty of builder-grade units on 1960s ranches in Unionville that lasted barely five seasons. We install only professional-grade caps from Gelco and Olympia Chimney, with stainless steel mesh and proper overhang to shed water away from the crown below.
Crown Repair
Crown repair in Farmington typically ranges $380-$720. The freeze-thaw damage we see on historic-district chimneys is often extensive, with the original lime-based mortar washed out and the brick beneath exposed. Our technicians remove the deteriorated material, form a proper concrete crown with minimum 2-inch overhang and drip edge, and seal it correctly. On active fireplaces in homes without clay liners, we always inspect the flue interior with our camera before capping, because a sound crown on a crumbling flue is a false economy.
Crown Coating
For crowns with minor cracking but intact structural integrity, crown coating in Farmington runs $240-$420. We use professional-grade flexible sealants formulated for Connecticut’s temperature swings, not the hardware-store brush-on products that crack by February. This is often the right choice for mid-century ranches in the Unionville section where the crown is poured concrete in decent shape but the surface has weather-checked. We’ll tell you honestly if coating is sufficient or if rebuild is the smarter long-term spend.
Multi-Flue & Custom Caps
Historic Farmington homes with stacked-brick chimneys serving two or more fireplaces need multi-flue caps sized to the full chimney top, not individual flue caps that leave the center wash exposed. These run $650-$1,200 installed, with custom copper or stainless fabrication at the higher end. We’ve measured and fitted caps on chimneys dating to the 1700s where no two flues are the same dimension, and where standard catalog caps simply don’t exist.

Trusted Brands We Service in Farmington
We stock and install professional-grade cap and crown materials from Gelco, Olympia Chimney, and Famco, with HeatShield crown coating products for appropriate repair scenarios. These aren’t builder-grade substitutes ordered from a catalog, and we don’t wait two weeks for parts to ship. Our trucks carry the standard inventory for Farmington’s common flue sizes, meaning most cap installations and crown repairs finish in the same appointment. When a custom cap is needed for a historic multi-flue stack on Main Street, we fabricate locally and return to install, typically within a week.
Common Chimney Cap & Crown Problems We See in Farmington Homes
- Freeze-thaw spalling on unlined historic chimneys. The Farmington River valley’s elevated humidity means moisture penetrates porous brick more readily than in surrounding hill towns. When January temperatures drop into the mid-teens, that moisture expands, spalling brick faces and eroding mortar joints from the crown down. We see this routinely on 18th-century chimneys in the historic district where no clay liner was ever installed.
- Galvanized cap rust-through on mid-century ranches. The ranches and split-levels in Unionville’s 1950s-70s developments often have original galvanized caps that rust out in 3-5 years given the local moisture load. Homeowners smell damp fireplace odors before they see the damage, by which point the flue tile top and crown wash are often compromised.
- Crown wash erosion hiding behind intact brick. On colonial and Federal-era homes along Farmington Avenue and Mountain Road, the crown wash (the thin cement layer over the brick top) deteriorates while the brick courses below look fine from the ground. Water enters through hairline cracks, freezes, and opens gaps that channel runoff directly into the flue cavity. Our camera inspection catches this before ceiling stains appear.
- Improper insert venting through uncapped flues. In the historic district, we regularly find wood stove or fireplace inserts installed decades ago, venting through original open-masonry flues with no cap, no liner, and often a crown that was never built to modern standards. This is a compliance and safety issue that requires more than a cap, and we’re direct with homeowners about what they’re actually dealing with.

Farmington cap and crown pricing runs comparable to West Hartford and slightly above Hartford proper, primarily due to the higher incidence of custom multi-flue caps on historic homes and the occasional need for scaffolding on tall colonial stacks. The actual labor and material rates are consistent across our service area, but Farmington’s housing stock skews older and more architecturally complex, which can increase project scope. We provide the same upfront pricing and $50-off repair offer regardless of town.
Every cap and crown job in Farmington is covered by our 90-Day Done Right Promise: if it’s not right, we come back and make it right, in writing, no paperwork and no arguing.

We document every installation with photos so there’s no dispute about what was done or when. Call (844) 803-1545 for a free estimate, and we’ll explain exactly what warranty applies to your specific job.
