We’ve been working on chimneys in New Canaan for over 42 years. The town’s inland position in Fairfield County, sitting above the frost line in a humid continental zone, creates a specific wear pattern on masonry that coastal communities don’t see in the same way. Long heating seasons running October through April, combined with wet nor’easters that saturate chimney crowns before temperatures drop below freezing, push mortar and brick through aggressive freeze-thaw cycles. In neighborhoods like Silvermine and the historic district around Main Street, we regularly find original clay-tile flue liners from the 1920s and 1930s that have simply reached the end of their service life. When you call us, you’re getting technicians who understand the difference between a pre-war colonial revival on Oenoke Ridge and a Harvard Five modernist home with an integrated stucco chase that requires specialized access planning.
Why Hearthstone Chimney Co. Is New Canaan’s Preferred Chimney Repair Company
New Canaan homeowners tend to stay in their homes for decades. They remember the contractor who showed up late, the one who added charges mid-job, the one who never returned the call. We built Hearthstone Chimney Co. in 1984 specifically for customers who have seen that movie before and don’t care to watch it again.
Our reputation here rests on documentation. Every inspection ends with photos you can see and a plain-English verdict you can understand. No jargon, no scare tactics, no pressure. The 90-Day Done Right Promise covers every repair in writing - if it’s not right, we make it right, no paperwork and no arguing. That’s been our standard since before most chimney companies in Fairfield County existed.

Most New Canaan repairs are scheduled within 48 hours, and our background-checked, uniformed technicians arrive with the materials to finish the job in one visit. The price we quote is the price on the invoice. A square deal, no surprises on the bill.
We know the local permitting process through the New Canaan Building Department, and we’re familiar with the specific challenges of working on architecturally significant properties where preservation standards matter. Our Chimney Repair team has documented experience with the non-standard flue geometries found in mid-century modern homes throughout the 06840 and 06842 ZIP codes.
Our Chimney Repair Services in New Canaan
Mortar Repointing
The mortar joints between your bricks are the first line of defense against water intrusion. In New Canaan’s older neighborhoods - particularly around Parade Hill and the Lakeview area - we find original lime-based mortar from the 1920s through 1950s that has simply powdered away after ninety years of freeze-thaw exposure. Our repointing matches the original mortar composition and compressive strength, using professional-grade materials from Olympia Chimney and Copperfield. We grind out the deteriorated joint to proper depth, never just smearing new mortar over old. Done right, repointing extends chimney life by decades and prevents the structural failure that leads to full rebuilding.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - accelerates dramatically when chimneys lack proper crown overhang or when waterproofing has failed. New Canaan’s combination of wet snow loads and rapid temperature swings makes this especially common on south-facing exposures where daily freeze-thaw cycles repeat through winter. We remove and replace spalled bricks with matching units, addressing the underlying moisture source so the problem doesn’t return in two seasons. For homes in the 06840 ZIP code with original architectural brick, we take particular care to source compatible replacements that preserve facade appearance.
Chimney Waterproofing
Standard brick is surprisingly absorbent. Without a breathable, vapor-permeable sealant, New Canaan chimneys draw in moisture that expands during freezing and destroys masonry from within. We apply professional-grade waterproofing agents from HeatShield and Famco that allow the chimney to breathe while repelling liquid water. Application timing matters here: we won’t seal a chimney that hasn’t been properly repaired and dried, because trapping moisture inside causes worse damage than no treatment at all. For properties near the Five Mile River watershed where groundwater pressure runs higher, we evaluate whether additional drainage improvements are warranted.
Flashing Repair
The intersection between chimney and roof is the most leak-prone point on most New Canaan homes. Original step flashing on colonial revivals often consists of single pieces of galvanized steel that have corroded through after eighty-plus years. On mid-century modern homes with flat or low-slope rooflines - common in the Harvard Five-influenced areas - the flashing detail is often integrated with the roofing membrane in ways that require specialized repair techniques. We fabricate and install custom flashing using DuraFlex and professional-grade sheet metal, with proper counterflashing reglets that shed water for the life of the roof. Most flashing repairs run $550-$1,200 in the New Canaan market and stop active leaks the same day.

Trusted Brands We Service in New Canaan
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from Olympia Chimney, Famco, Copperfield, DuraFlex, HeatShield, and Gelco - the brands that professional sweeps and masons specify when they’re doing their own homes. For Chimney Repair in New Canaan, this means faster turnaround because we’re not ordering parts; we have them. When we document your inspection with photos and recommend a specific product, it’s one we’ve installed hundreds of times and can stand behind.
Common Chimney Repair Problems We See in New Canaan Homes
- Crown cracking after wet nor’easters. New Canaan’s position inland from Long Island Sound doesn’t protect it from coastal storm tracks. When wet snow loads sit on concrete crowns and temperatures plunge overnight, thermal shock creates hairline fractures that widen each season. We inspect crown condition annually and recommend sealing or rebuilding before water reaches the flue.
- Original clay flue liner deterioration in pre-war homes. The colonial revivals and Tudors built between 1910 and 1940 throughout the historic core typically have unlined or single-wythe clay tile flues that have cracked from thermal cycling. These liners can’t contain creosote fires safely and allow combustion gases to migrate into wall cavities. Our Level-2 camera inspection documents exactly what condition your liner is in.
- Stucco chase deterioration on mid-century modern homes. The Harvard Five and Bauhaus-influenced homes from the late 1940s through 1960s often encase chimney structures in stucco that traps moisture against framing. We’ve developed specific protocols for these properties that address water damage without compromising architectural character - a concern we take seriously given the documented significance of New Canaan’s modernist housing stock.
- Flashing failure at chimney-roof intersections on complex rooflines. Many New Canaan homes have multiple roof planes, dormers, and valleys that create difficult flashing conditions. Original installations often relied on caulk and hope rather than proper metalwork. We fabricate custom solutions that work with your specific roof geometry, not despite it.
