We’ve been driving Route 189 and Simsbury Road to Granby jobs for over 42 years. We know the difference between a 1980s cape on a quarter-acre off Salmon Brook Street and an 1810 center-chimney farmhouse set back on Lost Acres Road. That matters because the cap and crown solutions for those two chimneys have almost nothing in common. Our Chimney Cap & Crown team treats every Granby chimney on its own terms, with a Level 2 camera inspection and photos you can see before we recommend anything.

Why Hearthstone Chimney Co. Is Granby’s Preferred Chimney Cap & Crown Company

Granby homeowners tend to stay put. The town’s large-lot zoning and working farmland character attract people who plan to live in their house for decades, not flip it in five years. That matches how we operate. Hearthstone Chimney Co. was founded in 1984, and we’re building a company that will still be answering calls in 2050. When we fit a cap or repair a crown, we do it knowing we’ll likely see that chimney again.

Our reputation here rests on three things. First, the 90-Day Done Right Promise in writing, no arguing. If a cap leaks or a crown coating fails because we missed something, we come back and make it right. Second, our Level 2 camera inspections end with photos the homeowner can see and a plain-English verdict. No mystery recommendations. Third, a live person answers every call 24 hours a day, 7 days a week. Not a voicemail, not a callback queue.

Our background-checked, uniformed technicians complete most jobs in a single visit, with no-hassle upfront pricing. The number on the estimate is the number on the invoice. We’ve learned that Granby customers, especially those in the historic districts near the center of town, have been burned by contractors before and remember it. We don’t give them reason to remember us that way.

Our Chimney Cap & Crown Services in Granby

Cap Installation

New cap installation on a Granby chimney runs $275-$650 for a standard single-flue stainless steel unit, or $800-$1,400 for a custom multi-flue cap on one of the town’s oversized historic chimneys. We size caps to the flue, not the other way around. On ridge-adjacent properties near the Metacomet traprock ridge, we use reinforced attachment methods because localized downdraft and wind-shear conditions here can lift or loosen poorly secured caps. That’s a real Granby problem we’ve documented on camera more than once.

Cap Replacement

When a cap is rusted, damaged, or missing entirely, replacement is straightforward until it isn’t. On Granby’s older farmhouses with multiple flues, we often find that the original cap was never properly sized for the flue arrangement, or that a previous installer used a builder-grade unit that lasted five winters instead of twenty. We replace with professional-grade materials from Gelco and Olympia Chimney, matched to your flue count and draft requirements. If wildlife from the McLean Game Refuge has nested in the uncapped flue, we handle removal before installation.

Crown Repair

Crown repair is where the industry’s worst upselling happens, so we’ll be direct. A typical crown repair in Granby runs $450-$950. We recently restored a failing chimney crown and installed a custom multi-flue cap on a 1790s farmhouse on Simsbury Road. The original crown had spalled and cracked, allowing water to deteriorate the mortar and rust the damper. After a Level 2 inspection with camera evidence, we applied a CrownCoat coating and fitted a copper cap sized for the three flues, resolving the downdraft issue the homeowners had been experiencing. Nothing was recommended before they saw the photos.

Crown Coating

For crowns with minor cracking but sound structural integrity, a professional crown coating costs $350-$650 in Granby. This is a preventive repair, not a cosmetic one. Granby’s colder, longer winters, sitting at higher elevation than the Farmington Valley floor, mean more freeze-thaw cycles that open small cracks into major water infiltration paths. We use HeatShield and CrownCoat products formulated for New England temperature swings. If the crown is too far gone, we’ll tell you plainly and show you why on camera.

Multi-Flue Cap

Multi-flue caps are essential for Granby’s 18th- and 19th-century farmhouses with oversized central chimneys. These chimneys were built for cooking hearths and whole-house wood heat, with two to four flues that each need individual protection. A custom multi-flue cap runs $900-$1,850 depending on size, material, and attachment complexity. We measure on site, fabricate to order, and install with proper clearances for each flue. This is not an off-the-shelf product, and it shouldn’t be treated like one.

Custom Cap

When standard sizes won’t work, we design and install custom caps in copper, stainless steel, or black galvanized steel. Custom work starts around $1,200 and can exceed $2,000 for large or architecturally specific installations. On historic properties in Granby, we match the cap to the period and the chimney’s scale. The result protects the flue without looking like an afterthought bolted to a landmark.

Trusted Brands We Service in Granby

We work exclusively with professional-grade brands: DuraFlex, HeatShield, Gelco, and Olympia Chimney. We don’t use builder-grade substitutes because they fail faster and cost more in the long run. For Granby customers, this means we stock common cap sizes and crown repair materials locally, so most jobs don’t wait on shipping. When we order custom, we know the lead times and communicate them upfront. No surprises on the bill, and no surprises on the schedule.

Common Chimney Cap & Crown Problems We See in Granby Homes

• Cap loss or damage from downdraft and wind-shear on ridge-adjacent properties. Granby’s proximity to the Metacomet traprock ridge creates localized wind conditions that can lift or loosen poorly attached caps. We see this on properties along the higher elevations near the Massachusetts border, where standard attachment methods simply don’t hold.
• Crown cracking and spalling due to freeze-thaw cycles in Granby’s colder, longer winters. The town sits at higher elevation than Hartford-area towns, extending the heating season by several weeks and exposing chimney crowns to more temperature swings. Water enters hairline cracks, freezes, and opens them into channels that destroy mortar and rust dampers.
• Uncapped flues attracting wildlife from the McLean Game Refuge. The refuge’s 4,000-plus acres of forested sanctuary sit directly within Granby, and technicians here routinely find raccoon, squirrel, and chimney swift nesting in uncapped or damaged flues. This is a wildlife-removal add-on that our colleagues in Simsbury or Avon encounter far less frequently. Uncapped old farmhouse chimneys are essentially a prime nesting invitation in this environment.
• Deteriorating clay-tile liners in unlined historic chimneys. Many Granby farmhouses have flues originally built for cooking hearths, with no liner or a failing clay-tile liner that crumbles into the smoke chamber. A cap can’t fix this, but it can prevent accelerated deterioration by keeping water and animals out while you plan the right repair.
