Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Our Chimney Repair Services in Larchmont
Mortar Repointing
In Larchmont, repointing isn’t a someday repair - it’s often the first thing we flag. The village’s direct Long Island Sound frontage exposes chimneys to salt-laden air that chemically attacks lime-based mortar in the 1910-1945 brick homes that dominate here. Mortar joints in Larchmont Manor degrade noticeably faster than identical construction just a few miles inland in White Plains. We grind out the failed joint to proper depth and repack with color-matched, professional-grade mortar formulated for coastal exposure. Typical repointing on a Larchmont chimney runs $1,200-$2,800 depending on access and how many courses need work.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is what happens when water gets in and freezes through Westchester’s 30-40 annual freeze-thaw cycles. In Larchmont, the damage starts faster because salt-air corrosion pits the chimney crown or rusts through a galvanised cap, letting water penetrate from above. We see this pattern constantly on homes near the Sound: the crown fails first, water migrates behind the brick, and freeze cycles pop the faces off. We replace spalled brick with matching units and address the water source so it doesn’t repeat. Spalling repair in Larchmont typically costs $850-$2,400.
Chimney Waterproofing
Waterproofing a Larchmont chimney means more than slapping on sealant. The coastal humidity here keeps masonry damp longer than inland Westchester, so breathability matters. We use professional-grade, vapor-permeable treatments from Copperfield and HeatShield that block liquid water while letting trapped moisture escape. For Sound-front homes, we also evaluate whether stainless steel caps and flashing are warranted over galvanised originals that will rust through again. Waterproofing treatments run $400-$950 for most Larchmont chimneys, with stainless cap upgrades starting around $380 installed.
Flashing Repair
Chimney flashing - the metal where your chimney meets the roof - is a common failure point in Larchmont’s coastal environment. Galvanised flashing rusts through in as little as 7-10 years here, compared to 15-20 inland. We replace with step flashing and counterflashing in compatible metals, sealed with professional-grade compounds. Because we stock parts locally and dispatch crews from our New York City office, turnaround is fast. Flashing repair in Larchmont typically runs $650-$1,400.

Common Chimney Repair Problems We See in Larchmont Homes
- Salt-softened chimney crowns. The concrete or mortar cap atop your chimney takes the brunt of coastal exposure. In Larchmont, we regularly find crowns that have cratered and spalled while the flue liner below is still sound. A stainless cap and Gelco crown coating often solve it without rebuilding.
- Rusted-through galvanised caps and flashing. That galvanised cap looked fine when installed. Ten years of salt air later, it’s perforated and funneling water straight into your brickwork. We replace with stainless or copper that won’t repeat the failure.
- Unused flues with third-degree creosote and active nesting. In Larchmont Manor, grand homes often have three or four chimneys, but owners may use only the living-room fireplace. Upper-floor and library flues sit unswept for a decade or more, building glazed creosote and hosting squirrels or birds the owner never suspects.
- Degraded mortar joints on multi-fireplace estates. Original lime mortar in these 1910-1945 homes was never meant to withstand salt-laden air. We find joints receded half an inch or more, letting water behind the wythe and accelerating freeze-thaw damage.

FAQs - Chimney Repair in Larchmont
Your Larchmont chimney crown degrades faster because salt-laden air off Long Island Sound chemically attacks the Portland cement and lime in the crown mix, while your brother’s inland chimney faces the same rain but none of the salt corrosion. The difference is dramatic - we see Sound-front crowns fail in 8-12 years that would last 20 inland. A Gelco crown coating and stainless cap replacement, rather than another galvanised lid, is usually the right fix. Call (914) 246-5794 and we’ll assess whether your liner is still sound beneath the damaged crown.
Yes, especially in Larchmont, because the inspection isn’t only about creosote - it’s about salt-air damage to mortar, crowns, and caps that progresses whether you light fires or not. On a Manor Lane Tudor Revival a few blocks off the Sound, our tech pulled a salt-softened chimney crown that had cratered and spalled across its top while the terra-cotta flue liner below was still sound, and we reset it with a stainless cap and Gelco crown coating instead of the original galvanised lid. The owner had called for a routine sweep on the living-room fireplace only; the upper-floor and library flues - unused for years - held third-degree creosote glaze and an active squirrel nest we cleared the same visit. Annual inspection catches what silence hides.
The chimney crown and top mortar joints fail first, followed by galvanised metal components. Salt air pits and cracks the crown, letting water into the brick below. That water freezes through 30-40 annual cycles and spalls brick from the inside out. Meanwhile, galvanised caps and flashing rust through, accelerating the water intrusion. Stainless replacement and proper waterproofing break this cycle. We document the progression with camera photos so you see exactly where your chimney stands.
Most Larchmont chimneys we see need repointing, not rebuilding. The key is whether the brick itself is sound and the structural wythe is intact. We grind test joints and camera-scan the flue to determine this. If the brick is spalled less than 25% of the face and the liner is structurally adequate, repointing with color-matched mortar and crown repair is the right call - typically $1,200-$2,800 versus $2,800-$6,500 for partial rebuild. We’ll show you the photos and give you a plain-English verdict, not a sales pitch. Call (914) 246-5794 for a free second opinion on any written estimate.
Not automatically. Many Larchmont homes built 1910-1945 have original terra-cotta liners that are still structurally sound, especially in flues that saw moderate use and were swept regularly. What matters is the condition we find on camera: cracked tiles, missing mortar between joints, or glaze buildup that narrows the flue. If the liner is sound, we document it and move on. If it’s compromised, we discuss DuraFlex stainless options or HeatShield resurfacing - both professional-grade solutions with no builder-grade substitutes. The inspection tells the story, not the age of the house.
