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.

AfterFast, Reliable Chimney Repair Across West Hills
Chimney repair in West Hills, NY typically costs between $350 and $4,500 depending on scope, with most standard repairs completed in a single visit and backed by our written 90-Day Done Right Promise. Our crews coordinate dispatch from our New York City office and serve West Hills homes directly, carrying DuraFlex liners, HeatShield resurfacing materials, and Copperfield caps on every truck so we don’t waste your time with return trips for parts.
We know the chimneys here. The large-lot colonials and Capes built from the 1950s through the 1980s along Sweet Hollow Road, Chichester Road, and the wooded streets backing up to West Hills County Park still run their original multi-flue masonry stacks. Many were never lined, or carry clay tile that’s now cracking after sixty-plus winters of freeze-thaw at elevation. When mortar starts dropping into the firebox or you smell your neighbor’s oil burner in your living room, that’s not a nuisance - it’s a sign the stack is failing and potentially drawing combustion gases where they don’t belong. Call us at (631) 776-4075. A live person answers, 24 hours a day.

Our Chimney Repair Services in West Hills
Chimney Rebuilding
Some West Hills chimneys have simply reached the end of their service life. The original fieldstone-and-brick stacks on older parcels near Jayne’s Hill, and the 1960s-70s masonry on the Ridgeline Drive corridor, often show compound failure: spalling brick, deteriorated mortar, cracked crowns, and compromised liners all at once. Rebuilding isn’t cosmetic - it’s structural safety. We dismantle only what’s unsound, salvage sound brick where possible, and rebuild to current code with proper clearance to combustibles and a new stainless or DuraFlex liner system. For West Hills homes with shared flue configurations, we re-engineer the separation so your fireplace and your neighbor’s furnace draw independently.
Chimney Waterproofing
At roughly 401 feet above sea level, West Hills catches wind that flatland Long Island towns don’t. That wind drives rain past cracked crowns and into porous masonry. Once water saturates the brick, winter freeze-thaw cycles open cracks wider each season. Our waterproofing uses Gelco’s vapor-permeable silane/siloxane formula - it keeps water out while letting trapped moisture escape, which is critical for West Hills chimneys that have already absorbed decades of weather. We apply it after any repointing or rebuilding, and we warranty the application. One treatment, properly done, protects for ten years.
Mortar Repointing
Repointing is the most common repair we perform in West Hills, and for good reason. The elevated, windswept terrain accelerates mortar joint erosion. When joints recede past a half-inch, water penetrates the wall, spalls the brick faces, and can destabilize the entire stack. We grind out failed joints to proper depth, match the original mortar composition for thermal compatibility, and tool the new joints to shed water. On a typical West Hills colonial with a two-flue stack, expect two to three days of scaffold work. We document the before condition with photos, and we show you the finished joints before we wrap.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is everywhere we look on older West Hills chimneys. It’s caused by water trapped inside the brick expanding through freeze cycles. Individual brick replacement is possible when the damage is isolated. When spalling is widespread, it’s usually a symptom of systemic water intrusion, and we recommend combining brick repair with crown rebuilding and waterproofing. We source matching brick when possible, or recommend a compatible replacement that blends with your home’s exterior.
Flashing Repair
Chimney flashing is the sheet-metal seal where your stack penetrates the roofline. In West Hills, wind off Jayne’s Hill works flashing loose over time, and the mature oak canopy drops debris that traps moisture against the seal. Failed flashing is the leading cause of interior water damage we see - stained ceilings, rotted roof decking, damaged insulation. We remove the old flashing, inspect the roof deck for rot, and install new step and counter flashing with proper soldered or sealed joints. On steep pitches common to West Hills’s Capes and colonials, we use additional ice-and-water shield as backup protection.
Tuckpointing
Tuckpointing is the decorative and functional art of cutting narrow grooves in mortar joints and filling them with a contrasting color to create the appearance of fine joints. On West Hills’s historic and estate-style homes, original tuckpointing adds architectural character worth preserving. Our masons match the original profile and color, maintaining the home’s period detail while restoring weather resistance.

Trusted Brands We Service in West Hills
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - brands that stand up to West Hills’s wind and weather. DuraFlex liners handle the thermal cycling of shared flue systems. HeatShield resurfacing restores deteriorated clay tile without full liner replacement when the damage is moderate. Copperfield caps stop the rain and wildlife that plague uncapped flues under the West Hills canopy. Because we stock these parts, most West Hills repairs don’t wait on ordering.
Common Chimney Repair Problems We See in West Hills Homes
- Wind-driven rain penetration at the crown. The exposed ridgeline elevation of West Hills means chimney crowns take a beating. A hairline crack in the crown cement becomes a water highway during a nor’easter, saturating the flue and the masonry below. We rebuild crowns with proper slope and drip edges, then cap them to break the wind.
- Shared-flue cross-contamination. Attached homes and close-set properties in West Hills often have flues serving multiple appliances. When a liner cracks or a damper fails to seal, your neighbor’s furnace exhaust can draw into your living space, or your fireplace smoke can backdraft into their utility room. This is a repair issue we take seriously - it involves carbon monoxide exposure, not just odor.
- Wildlife blockage in uncapped flues. The dense oak and hardwood canopy that makes West Hills beautiful also makes it prime habitat for raccoons and chimney swifts. We regularly remove nests from uncapped flues on wooded streets near West Hills County Park, following New York DEC guidelines for wildlife-compliant removal before any inspection or cleaning proceeds.
- Accelerated mortar joint erosion from freeze-thaw cycling. West Hills’s elevation means colder overnight lows and more rapid temperature swings than lower Long Island communities. Saturated mortar joints go through more freeze-thaw cycles per winter, eroding faster and requiring repointing years sooner than flatland chimneys of the same age.

FAQs - Chimney Repair in West Hills
West Hills sits at roughly 401 feet on Jayne’s Hill, the highest point on Long Island, which exposes chimneys to stronger prevailing winds and more severe freeze-thaw cycling than flatland towns experience. That elevation drives wind-driven rain into crowns and accelerates mortar erosion at a rate South Huntington or Melville simply don’t see. Call (631) 776-4075 for a free inspection and exact repair quote.
Yes - shared flues are a documented carbon monoxide and cross-contamination hazard when liners crack or dampers fail to seal. In West Hills’s attached and close-set housing, we regularly find combustion gases migrating between flue channels. We separate the flues with proper liner installation and damper repair so each appliance draws independently and safely. Call (631) 776-4075 to schedule a camera inspection that will show you exactly what’s happening inside your stack.
Yes, frequently enough that we expect it on first-season calls to uncapped chimneys on wooded streets near West Hills County Park and the Jayne’s Hill ridgeline. The dense oak canopy provides ideal nesting habitat. We remove nests under New York DEC wildlife guidelines before any cleaning or inspection, then install a Copperfield cap to prevent recurrence. Call (631) 776-4075 if you hear scratching or see debris dropping into your firebox.
Repointing suffices when the brick faces are sound and only the mortar joints have eroded. A full rebuild becomes necessary when spalling has compromised the structural brick, when the stack leans, or when multiple systems (crown, liner, flashing, masonry) have failed together. Our Level-2 camera inspection and photo report show you which category you’re in, with no pressure either way. Call (631) 776-4075 for your free assessment.
Yes - the National Fire Protection Association Standard 211 recommends annual inspection of all chimney and venting systems regardless of use, because deterioration from weather, wildlife, and structural settling continues whether you light fires or not. In West Hills, where wind and freeze-thaw stress masonry year-round, the annual inspection often catches crown cracks and mortar failure before they become rebuilds. Call (631) 776-4075 to schedule; estimates are free.
