Call (844) 660-6590

We’re based in Yonkers and regularly on the road to Larchmont — usually within 30 minutes for calls along Boston Post Road, Palmer Avenue, or down toward the Manor neighborhood. Gary Murphy, our owner and lead technician, handles every job personally. We’ve spent 11 years specializing exclusively in chimney work, and our Chimney Repair team knows the village’s housing stock inside out: the 1890s Victorians, the 1920s Tudor Revivals, the substantial Colonials from the 1930s and 40s. These aren’t generic suburban chimneys. They’re century-old masonry systems built with original clay tile flue liners and multiple flues, now facing accelerated decay from salt-laden air off Long Island Sound. When you call us at (844) 660-6590, you’re getting the decision-maker on your roof — not a subcontractor working under our name.

Why Sterling Chimney Cleaning Yonkers Is Larchmont’s Preferred Chimney Repair Company

Our reputation in Larchmont has been built job by job, not through advertising. Over 1,100 homeowners across Westchester have trusted us with their chimneys, and our 1,142 verified reviews averaging 4.7 stars reflect consistent performance on real, complex jobs — not routine sweeps alone. Larchmont customers specifically mention the difference it makes when Gary leads every job himself: no handoffs, no “the crew will handle it,” just direct accountability from the person who owns the business and climbs the ladder.

Response time matters for chimney damage, especially after winter freeze-thaw cycles. We typically reach Larchmont properties within 30–45 minutes of a call, whether you’re near the Larchmont train station, up in the Wykagyl border area, or down in Larchmont Manor where the Sound exposure is most severe. That local speed matters because water entry through a compromised crown or flashing doesn’t wait — and neither do we.

Our familiarity with Larchmont’s specific conditions runs deep. We know that a chimney inspection here isn’t the same as one in White Plains or Yonkers. The salt air, the age of the housing stock, the prevalence of original clay liners — these factors change what we look for and what we find. We’ve learned to expect the unexpected: dampers rusted solid despite minimal fireplace use, mortar washed out from marine humidity cycles, liner damage that standard camera inspections in inland homes rarely match.

Our Chimney Repair Services in Larchmont

Mortar Repointing

Mortar repointing in Larchmont runs $850–$2,200 depending on the chimney’s height, accessibility, and the extent of joint erosion. In this village, we routinely see mortar deterioration that’s 10–15 years ahead of what we’d expect inland. The combination of salt-laden air and aggressive freeze-thaw cycling — especially on homes within a few blocks of Long Island Sound — washes out mortar joints faster than almost anywhere else we work in Westchester. We grind out the deteriorated mortar to proper depth and repoint with color-matched, high-lime mortar formulated for coastal exposure, not the quick-set products some crews use that crack within two seasons here.

Spalling Brick Repair

Spalling brick repair in Larchmont typically costs $1,200–$3,500, with full-course replacement at the higher end. The flaked, popped faces you see on chimney bricks here aren’t just cosmetic. They’re the result of water penetrating the brick, freezing, and expanding — a process amplified by the Sound’s marine humidity. In Larchmont Manor especially, where century-old brick was often laid with softer, more porous mortar beds, we see spalling concentrated on the seaward faces of chimneys. We remove damaged bricks, source matching replacements when possible, and address the water source — usually failed crown or cap — so the repair lasts.

Chimney Waterproofing

Professional chimney waterproofing in Larchmont costs $400–$900 for standard application, with additional crown repair or cap replacement billed separately. Given the village’s coastal position, we treat waterproofing as essential maintenance, not an upsell. We use vapor-permeable sealers — specifically products from our professional-grade lines — that allow the chimney to breathe while blocking liquid water. Trapping moisture inside with cheap non-breathing sealers is a common mistake we correct on Larchmont homes where previous owners or contractors took the wrong approach. The goal is keeping water out without accelerating the internal deterioration that salt air already encourages.

Flashing Repair

Flashing repair in Larchmont ranges from $350 for simple step-flashing resealing to $1,800–$2,800 for complete counter-flashing and step-flashing replacement on complex rooflines. Many of Larchmont’s older homes have undergone multiple roof replacements without proper flashing attention, leaving gaps where water runs directly into the attic space. We see this particularly on the steep-pitched roofs of Tudor Revival homes in the Manor and along Boston Post Road corridors. Our flashing work integrates with existing roofing or coordinates with your roofer when a full replacement is needed — we don’t caulk over problems and call it done.

Chimney Rebuilding

Partial chimney rebuilding in Larchmont starts around $4,500 and can reach $8,000+ for multi-flue structures with complex crown reconstruction. Full rebuilds are less common than targeted repairs, but when we encounter a 1920s chimney with failed liner, spalled brick through multiple courses, and a compromised foundation, rebuilding from the roofline up becomes the only sound approach. We handle this in-house — no contractor handoffs — using Olympia Chimney components and proper structural reinforcement. For Larchmont’s landmark-era homes, we match existing brick and mortar profiles to preserve architectural integrity.

Tuckpointing

Tuckpointing — the fine-art removal and replacement of mortar joints for both structural and aesthetic restoration — runs $1,500–$4,000 in Larchmont depending on chimney size and joint condition. On the village’s pre-war masonry, tuckpointing isn’t just maintenance; it’s preservation. We match joint profiles and mortar composition to original specifications, using techniques appropriate for historic construction rather than speed-focused methods that compromise the chimney’s long-term stability.

Trusted Brands We Service in Larchmont

We install and repair with professional-grade materials: HeatShield for ceramic flue liner restoration, Gelco and Famco for caps and dampers designed to withstand coastal corrosion, and Olympia Chimney for stainless steel liner systems and components. We don’t source from big-box retailers or use whatever’s cheapest that week. For Larchmont’s salt-air environment, material selection matters enormously — a standard galvanized cap that lasts 8 years inland might fail in 3 here. We stock common replacement parts and can typically source specialized components within 24–48 hours, meaning Larchmont customers aren’t waiting weeks for repairs while water continues entering their chimney system.

Common Chimney Repair Problems We See in Larchmont Homes

• Salt-air corrosion of metal components. In Larchmont Manor’s waterfront streets, we routinely find chimney caps and dampers rusted nearly through — not from fireplace use, but from year-round salt air off Long Island Sound. Homeowners who haven’t burned a fire in years are often shocked to discover their damper has seized completely, creating a direct path for water, pests, and conditioned-air loss.
• Accelerated mortar joint erosion from freeze-thaw cycling. The village’s position at the water’s edge means marine humidity penetrates masonry joints, then freezes and expands with particular severity each winter. Post-winter inspections in Larchmont regularly uncover structural damage that wouldn’t yet appear on equivalent chimneys in White Plains or Yonkers, just a few miles inland.
• Original clay tile liner failure. Larchmont’s housing stock — overwhelmingly pre-World War II, with many homes built between 1890 and 1940 — contains clay flue liners now 75–130 years old. These liners commonly show cracking, offset joints, and mortar deterioration that standard brush cleaning reveals. What starts as a routine sweep call often becomes a liner assessment once we camera the flue.
• Crown deterioration from combined moisture and temperature stress. Chimney crowns on Larchmont homes take a beating: summer humidity, winter freeze-thaw, and the thermal shock of occasional fireplace use on century-old concrete. We see more crown reconstruction needs here than in comparable inland villages, and we address them with proper crown-forming techniques and materials — not surface-level patching that fails within a season.
