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

Nashua’s chimney problems are not generic. The downtown colonials near the Millyard, the post-war ranches off Amherst Street, and the ’80s subdivisions spreading toward the Massachusetts line each present different cap and crown failures, and we’ve worked on all of them. Our Chimney Cap & Crown in Nashua crew knows the difference between a clay-tile flue on a 1920s brick stack and a metal chase cover on a prefab fireplace, because misidentifying one for the other leads to the wrong repair and another leak six months later.

We’ve earned a strong local reputation across Hillsborough County by documenting every inspection with photos the homeowner can see and delivering a plain-English verdict before any work begins. Our Level-2 camera inspections show you exactly where the crown has cracked or the cap has pulled loose, not because it’s flashy, but because a craftsman shows his work.

Response time to Nashua averages same-day or next-day during peak season, and emergency calls for active water intrusion get priority scheduling. We’ve had technicians on Crowley Street in the 03061 ZIP by mid-morning after a dawn call about a crown washed out in an overnight storm.

Our 90-Day Done Right Promise applies to every job in Nashua, in writing, with no arguing. If the repair doesn’t hold, we come back. That’s how a company that’s been here for over 42 years stays in business, and how we plan to be here thirty years from now.

Our Chimney Cap & Crown Services in Nashua

Cap Installation

New cap installation in Nashua typically serves homeowners who’ve never had one, or whose original cap blew off in a nor’easter. We measure your flue count and dimensions on site, then fabricate or source a proper fit from professional-grade materials. In the 03062 and 03064 subdivisions, we frequently install multi-flue caps over factory-built chimneys that were sold with cheap galvanized covers now rusted through after thirty years. A proper copper or stainless cap from Copperfield or Famco stops water entry, keeps squirrels and starlings out of the flue, and vents properly so smoke draws correctly. Most installations take under two hours.

Cap Replacement

Replacing a failed cap is one of the most common calls we get after Nashua’s late-winter freeze-thaw cycles. The existing cap may be rusted, improperly sized, or missing entirely after a windstorm. We remove the old unit, inspect the flue tile beneath for hidden damage, and install a replacement that actually fits. Homeowners near Greeley Park in 03064 often call us after discovering their “cap” was actually a piece of bent flashing that funnelled water into the chimney rather than away from it. We don’t reuse old hardware. The new cap gets secured with proper fasteners and sealant rated for New Hampshire temperature swings.

Crown Repair

The concrete crown at the top of a masonry chimney is not decorative. It’s the structural layer that sheds water away from the flue and the brick below. In Nashua’s climate, crowns crack and spall faster than in drier parts of the state because Merrimack River valley humidity keeps masonry damp, and repeated freezing expands those cracks wider each season. We repair crowns by removing loose material, applying a bonding agent, and pouring new concrete sloped properly for drainage, or we apply a specialized crown coating when the damage hasn’t reached the structural layer. Either way, we extend the crown edge beyond the brick to form a proper drip edge, something we see missing on half the older homes we inspect near Main Street.

Crown Coating

For crowns with hairline cracking but sound underlying structure, a professional-grade flexible coating from HeatShield or similar compounds can add years of life without full reconstruction. This is often the right choice for Nashua’s 1970s and ’80s colonials where the crown was poured thin to begin with and is now spider-webbed but not yet failing. We clean the surface, fill cracks, and apply the coating in weather-appropriate conditions. It’s not a permanent fix for a crown that’s already crumbling, but for the right chimney, it’s a square deal that puts off major rebuild expense.

Trusted Brands We Service in Nashua

We don’t use builder-grade substitutes that fail in three seasons. For cap and crown work in Nashua, we specify materials from Famco, Copperfield, and DuraFlex, brands that have proven themselves in northern New England’s freeze-thaw environment. We stock common cap sizes and crown repair compounds locally, so most Nashua homeowners aren’t waiting weeks for parts to ship. When a custom cap is needed for an oversized or unusual flue configuration, we fabricate to spec and install with the same single-visit efficiency. The materials cost a bit more than big-box alternatives. They also last.

Common Chimney Cap & Crown Problems We See in Nashua Homes

• Crown washout after freeze-thaw cycles. Nashua’s position in the Merrimack River valley means masonry stays damp longer than in drier NH cities, and the repeated hard freezes each late winter break apart concrete crowns that were already marginal. We see this most on pre-1940 brick homes near the Millyard where the original crown was never properly maintained.
• Missing or rusted caps on prefab fireplaces. The southern ZIP codes, 03062 and 03064, are full of ’80s and ’90s colonials with factory-built fireplaces whose cheap original chase covers have corroded through. Homeowners often don’t realize water is entering until the firebox rusts or refractory panels crack.
• Improperly sloped crowns pooling water. A crown must shed water to the edge, not sit flat. Nashua’s heavy snow loads and spring rains make flat or reverse-sloped crowns fail fast. We re-pitch or rebuild to proper specifications.
• Squirrel and bird entry through open flues. Without a cap, Nashua’s mature tree canopy, especially in the older neighborhoods off Concord Street, provides easy access for wildlife. A proper cap with mesh screening solves this permanently.
