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 Liner & Rebuild Across South Hempstead
Chimney liner replacement and chimney rebuild work in South Hempstead typically runs $1,800-$6,500 depending on scope, and most jobs are completed in a single visit after our Level-2 camera inspection. If your home is one of the postwar Cape Cods or ranches built during Nassau County’s 1945-1965 boom, there’s a strong chance your clay-tile flue was sized for oil heat, not the gas furnace or boiler running through it now. That’s not a guess - it’s what our Chimney Liner & Rebuild team documents on camera week after week in this hamlet.
We’ve been dispatching crews to South Hempstead from our New York City office for decades, and we know the local housing stock the way a mason knows his trowel. The salt air off the Great South Bay, the nor’easters that drive rain into aging crowns, the original clay liners now pushing 70 or 80 years - these conditions shape every recommendation we make. When you call (631) 735-5125, a live person answers, 24 hours a day. We’ll schedule your inspection, walk you through the camera footage, and give you upfront pricing before any work begins.

Our Chimney Liner & Rebuild Services in South Hempstead
Stainless Steel Liner Installation
A stainless steel liner is the permanent solution for most South Hempstead chimneys with deteriorated clay tile. We use insulated 316Ti stainless steel from trusted manufacturers, properly sized to your appliance’s BTU output and venting requirements. For the gas conversions common in this area, we typically drop a 4-inch or 5-inch insulated liner into an oil-era flue that was originally 8 inches or larger. The insulation maintains proper draft temperature and prevents condensation that leads to creosote buildup. Our stainless installations carry the 90-Day Done Right Promise, and we document the before-and-after with camera footage for your records.
Flexible Liner
Flexible liners solve the offset and bend problems we find constantly in South Hempstead’s postwar construction. Many of these chimneys were built with slight offsets or narrow smoke chambers that make rigid stainless installation difficult or impossible. A DuraFlex or Olympia Chimney flexible liner navigates these irregularities while still providing a continuous, properly sized venting path. We see this especially in the split-levels and ranches off Jerusalem Avenue and in the blocks south of Merrick Road, where chimney construction was often expedited during the 1950s building rush. Flexible liners are our go-to recommendation when a rigid liner won’t seat correctly or when the chimney has settled slightly over sixty-plus years.
Liner Replacement
Liner replacement is the core service we perform in South Hempstead, and it’s almost always driven by the oil-to-gas conversion problem. The original clay tile was engineered for the high temperatures and strong draft of an oil burner. A modern high-efficiency gas appliance produces cooler exhaust that moves more slowly through an oversized flue, allowing condensation to collect on the tile surface. That moisture seeps into cracks, freezes and expands, and progressively destroys the liner. Meanwhile, the slower exhaust can backdraft into the home. We remove the failed clay tile, inspect the surrounding masonry with our camera system, and install a new liner properly sized to the appliance. Nothing is recommended without photo evidence you can see yourself.
Partial Rebuild
Partial rebuilds are common in South Hempstead because the salt-laden air off the Great South Bay accelerates mortar joint erosion faster than almost anywhere else in Nassau County. We regularly rebuild the top four to six feet of chimney stack, replacing spalled brick and repointing joints before installing a new liner. Attempting to line a chimney with compromised structural integrity is putting a new pipe in a collapsing building. Our partial rebuilds use matching brick where possible and always include a new concrete crown with proper drip edge and step flashing detail. The liner installation follows only after the masonry is sound.

Trusted Brands We Service in South Hempstead
We stock professional-grade materials from DuraFlex, Olympia Chimney, Famco, and Copperfield - the brands that professional sweeps specify, not the builder-grade substitutes some operators use. For South Hempstead homeowners, this means faster turnaround because our trucks carry the common liner diameters and fittings for the gas-conversion work this market demands. When we recommend a DuraFlex flexible liner or an Olympia Chimney stainless system, it’s because we’ve installed hundreds of them and we know how they perform in salt-air conditions. We don’t experiment with your chimney.
Common Chimney Liner & Rebuild Problems We See in South Hempstead Homes
- Gas appliances venting into unlined oil-era flues. The most dangerous pattern we document: a furnace or boiler installed in the last decade still exhausting into an original 8-inch clay flue, cracked and oversized, with no liner and often no permit. Our camera inspection reveals the hazard, and we size a new insulated liner to the appliance’s specifications.
- Salt-air mortar erosion requiring partial rebuild before lining. The prevailing winds off the Atlantic carry corrosive salt that breaks down mortar joints on South Hempstead’s exterior stacks. We rebuild the compromised section first, then install the liner in sound masonry.
- Nor’easter water intrusion destroying smoke chambers and dampers. Wind-driven rain enters through failed crowns and step flashings, rusting metal components and saturating masonry. We see this after every major coastal storm, and we address the water entry before any liner work proceeds.
- Cracked clay tiles patched instead of replaced, trapping creosote. Some sweeps brush past cracked tile and call it clean. The cracks harbor third-degree creosote that no brush removes, creating a fire hazard and obstructing draft. HeatShield repair works for minor cracking; full replacement is required when the damage is extensive.

FAQs - Chimney Liner & Rebuild in South Hempstead
Yes, almost certainly. The original clay-tile flue in your South Hempstead home was sized for the high-BTU draft of an oil burner, and a modern gas appliance produces cooler, slower exhaust that will not properly vent through that oversized channel. The result is condensation, backdraft risk, and progressive liner damage that Town of Hempstead inspectors now flag as a code violation. Call (631) 735-5125 for a camera inspection - estimates are free, and we’ll show you exactly what your flue looks like inside.
A standard sweeping includes a visual inspection from the top and bottom, but it does not include the Level-2 camera inspection required to document liner condition throughout the flue length. We recommend the camera inspection for any South Hempstead home with a clay-tile liner over 40 years old, or any home that has converted from oil to gas. The $199-$289 camera service includes photos you keep and a written verdict on liner integrity.
A cracked tile allows exhaust gases, including carbon monoxide, to escape the flue and enter wall cavities or living spaces. In South Hempstead’s postwar chimneys, we also find that cracks trap creosote that brushes cannot remove, creating a concentrated fuel source for chimney fires. The salt-air moisture accelerates both problems by expanding freeze-thaw cycles inside the cracks. A cracked tile is not a maintenance item to defer - it’s a documented hazard that camera inspection reveals.
No. An unlined or oversized clay-tile flue serving a gas appliance will fail Town of Hempstead building inspection. The town requires proper venting sized to the appliance’s input rating, and an oil-era flue does not meet that standard. We document the non-compliance with our camera system, specify the correct liner size from manufacturer tables, and provide the inspection documentation your permit application requires. Call (631) 735-5125 - we handle this regularly and can walk you through the process.
We rebuild any compromised masonry before liner installation, because a liner in a failing stack is a waste of your money. In South Hempstead, this typically means addressing crown cracks, deteriorated step flashing, and spalled brick that salt air has damaged. Our partial rebuilds include a new poured concrete crown with proper overhang and drip edge, plus counter-flashing integration. The liner goes in only after the structure is sound. That’s the craftsman sequence, and it’s how we avoid callbacks.
