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 Elmont
If you own a home in Elmont built between 1945 and 1965, your chimney was almost certainly constructed for an oil-burning furnace, not the gas unit now venting into it. That mismatch is the root cause of most chimney repairs we perform across Elmont, from spalling brick on Hempstead Turnpike-adjacent Cape Cods to failed flashing on split-levels near Dutch Broadway. Our Chimney Repair crews serve Elmont from our New York City dispatch office, and we walk every job with a written price, camera documentation, and a named technician. Call (516) 240-9612 for a free estimate on any repair, from mortar repointing to a full flue liner replacement.
Why Level Two Chimney Jamaica Is Elmont’s Preferred Chimney Repair Company
Elmont’s housing stock is almost entirely postwar tract construction: Cape Cods, ranches, and early split-levels built fast during the Nassau County suburban boom. The brick used in those quick-build chimneys is softer and more porous than what you’d find in pre-war masonry, which means mortar joints fail sooner and face brick spalls under decades of freeze-thaw cycles. Our technicians know the difference between a chimney that needs repointing and one that needs rebuilding, and we show you the camera footage before recommending either.
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and every single one included a written price before work started and a photo record when it was done. That’s not a marketing promise. It’s Clause 1 and Clause 4 of the Haven Standard, the inspection and documentation protocol our company has operated under since its founding. Elmont homeowners who call us get a background-checked, uniformed technician with a license number on the page and a text when they’re on the way. Calls are answered by a live person, 24/7, not a voicemail.
What builds trust in Elmont isn’t a longevity claim. It’s the archive. Every visit produces documented camera footage, moisture readings, and a written scope of work. If you get a written estimate from another chimney company, bring it to us. We offer a free second opinion on any written quote, and we’ll tell you plainly if the work can wait or if it can’t.
Our Chimney Repair Services in Elmont
Mortar Repointing
Repointing is the most common repair we perform on Elmont’s postwar chimneys, and it’s the one most often oversold by companies that push a full rebuild when joints are only partially deteriorated. Repointing removes the failed mortar between bricks and replaces it with fresh mortar matched to the original’s compressive strength. On Elmont’s 1950s-era Cape Cods and ranches, the original mortar is often lime-based and softer than the brick around it, which means using a modern high-strength mortar actually accelerates brick failure. We match the mortar, not just the color. Expect to pay $800 to $1,800 for a typical partial repointing job on an Elmont chimney, depending on access and how many faces need work.
Spalling Brick Repair
Spalling is the flaking, chipping, or popping of brick faces, and Elmont sees more of it than most Long Island towns because of two factors: the soft postwar brick used in 1945-1965 construction, and the salt-laden Atlantic air that’s only 15 miles away. When brick faces spall, water enters the chimney’s interior, freezes, and expands, accelerating the damage. We replace spalled brick with units rated for exterior freeze-thaw exposure and repoint the surrounding joints so the repair blends into the existing chimney. A focused spalling repair on an Elmont chimney typically runs $600 to $1,500, while full-face rebuilding can reach $3,000 to $6,000 depending on the extent.
Chimney Waterproofing
Waterproofing is the preventive repair Elmont homeowners skip because the damage hasn’t become visible yet. A breathable siloxane-based waterproofing treatment, applied after repointing and crown repair, prevents water absorption while still allowing the chimney to expel moisture from within. It’s a one-day job that costs $400 to $900 for a typical Elmont residential chimney. Where it matters most in Elmont is on chimneys facing south and west, the sides that take the brunt of nor’easter-driven rain and wind. If your chimney’s south face shows white efflorescence, the brick is already absorbing water, and waterproofing after repair is the difference between a five-year fix and a twenty-year fix.
Flashing Repair
Flashing is the metal barrier where the chimney meets the roof, and it’s the first thing to fail on Elmont’s ranches and Cape Cods because of ice damming and the repeated thermal expansion of cheap original flashing. When flashing pulls away from the brick, water follows the chimney into the attic and down the interior walls, often showing up on second-floor ceilings as brown stains that homeowners mistake for roof leaks. We remove failed flashing, inspect the underlying underlayment, install new step and counter flashing from Copperfield, and seal every seam with high-grade polyurethane. Flashing repair in Elmont typically costs $500 to $1,200 depending on the chimney’s pitch and roof access.

AfterTrusted Brands We Service in Elmont
We stock repair materials from DuraFlex, Copperfield, and Famco for our Elmont calls, which means we can often complete liner and flashing work without a second visit. When an Elmont homeowner needs a stainless steel liner to replace an oil-era clay tile flue, we use DuraFlex flex-liners sized to the exact appliance BTU output, not just the chimney’s diameter. Crown repair and flashing work uses Copperfield products, and we keep common dimensions on our trucks. None of this is an upcharge. Materials are procured through Haven’s buying network specifically to keep customer pricing honest, which is why our written estimates in Elmont are consistently lower for equivalent scope than companies that source parts piecemeal.
Common Chimney Repair Problems We See in Elmont Homes
- Oversized oil-era flues on gas heat: The original 8-inch clay tile liners built for oil burners are far too large for modern gas furnaces, which exhaust at lower temperatures and velocities. The result is chronic condensation inside the flue that eats through clay tile and stains interior walls with white efflorescence. We see this on nearly every unlined gas-vented chimney in Elmont, and it’s fixed with a properly sized stainless liner, not a patch.
- Spalled brick faces from salt air and freeze-thaw: Elmont’s soft 1950s brick absorbs water easily, and the salt-laden air from 15 miles away accelerates the erosion. When water freezes inside the brick, the face pops off. Spalling brick is a structural issue, not cosmetic, and it compounds fast on chimneys near the Cross Island Parkway where winter road salt aerosolizes.
- Failed flashing on Cape Cods and ranches: The original flashing on Elmont’s postwar homes was often galvanized steel with a short service life. Ice damming along rooflines and repeated thermal expansion pull it away from the brick. If you have a water stain on a bedroom ceiling near the chimney, the flashing is the likely culprit before the roof is.
- Backdrafting and carbon monoxide risk in split-levels: Split-level homes in Elmont have living spaces that straddle the chimney’s midpoint. When an oversized flue can’t maintain draft, combustion gases spill back into the house during long furnace runs on cold nights. If you hear a musty smell near the fireplace or your CO detector trips when the heat kicks on, call for a Level 2 camera inspection immediately.
Pricing for Chimney Repair in Elmont, NY
A typical chimney repair job in Elmont runs between $500 and $1,800, with most homeowners paying around $900 to $1,400 for the most common work: repointing, flashing replacement, and crown sealing. Liner replacement for an oil-to-gas conversion, where the original oversized clay tile flue is replaced with a correctly sized stainless unit, runs $2,200 to $4,500 depending on the chimney’s height and access. Full chimney rebuilds in Elmont start around $4,500 and can reach $9,000 for two-story structures with extensive spalling. The factors that move the price are scaffold needs, roof pitch, access from Dutch Broadway-area alleys versus open yards, and whether the original brick can be salvaged. We provide a written line-item price before any work begins, and a free second opinion on any competitor’s written estimate. Call (516) 240-9612.

FAQs - Chimney Repair in Elmont
The white staining is efflorescence, and in Elmont it’s almost always caused by acidic condensation from a gas furnace venting into an oversized, oil-era clay tile flue that was never relined. The condensation leaches through the brick and leaves mineral deposits on the surface. It’s a sign of active liner deterioration, not just cosmetic staining, and it typically signals that the flue needs a camera inspection and likely a properly sized stainless liner. Call (516) 240-9612 and we’ll scope it and show you the footage.
Yes, if your home still has the original clay tile liner from its oil-burning era, a gas-suitable liner is the single most valuable repair you can make. Elmont’s postwar homes were built with 8-inch flues designed for high-temperature oil exhaust. Modern gas furnaces run cooler and slower, so the exhaust condenses inside the oversized flue. That condensate is acidic, and it eats through clay tile from the inside out. A correctly sized DuraFlex stainless liner solves the problem permanently. Liner replacement typically runs $2,200 to $4,500 in Elmont.
Nor’easters drive heavy, wind-blown rain against the south and west faces of Elmont’s chimneys, and that’s exactly where flashing fails first. On a Cape Cod, the chimney sits below the roofline’s peak, so water sheets down the roof and slams into the flashing at the back of the chimney. On a ranch, the chimney is more exposed and takes the wind-driven rain directly on the face brick. Both conditions accelerate flashing pull-away and water penetration. If you see a ceiling stain after a nor’easter, the flashing is usually the point of entry, and repair costs $500 to $1,200.
Spalling is when the face of a brick flakes off or pops away from the body of the brick. In Elmont, it’s common because the brick used in 1945-1965 tract construction is softer and more porous than modern brick, and the salt-laden Atlantic air 15 miles away accelerates water absorption. When absorbed water freezes, it expands and shatters the brick face. Spalling is structural: it exposes the softer interior of the brick to faster erosion. We replace spalled brick with freeze-thaw-rated units and repoint the surrounding joints, typically for $600 to $1,500 depending on how many faces are affected.
You need a Level 2 inspection, which includes a camera scan of the flue interior, whenever there’s been a change to the system: a new furnace, a change from oil to gas, a chimney fire, a property sale, or visible damage like spalling or efflorescence. In Elmont, we strongly recommend a Level 2 for any home built before 1965 that has not been relined, because the oil-to-gas conversion is exactly the condition that hides liner failure. A Level 2 is included with every repair quote we issue, and you’ll see the camera footage yourself. Call (516) 240-9612 to schedule one.
