We’ve been serving Nassau County communities for over 42 years, and Manhasset’s chimneys have taught us plenty.

Our technicians know to check for this damage first, not last.
Homeowners in the 11030 ZIP call us because we document every inspection with photos and a plain-English verdict. No jargon, no scare tactics. Frank Calucci built this company in 1984 on the principle that a square deal earns more trust than a hard sell, and that hasn’t changed.

Our Chimney Liner & Rebuild Services in Manhasset
Stainless Steel Liner Installation
Manhasset’s estate homes with their multi-flue chimneys demand stainless steel liners that can handle the thermal stress of modern gas appliances while fitting inside oversized coal-era flues. We install DuraFlex 316Ti stainless steel liners, the alloy specified for condensing appliances and high-efficiency boilers. In a typical Manhasset relining, we’ll drop a 6-inch or 7-inch liner down a 12×12 or 10×10 flue originally built for coal, then seal the annular space with HeatShield to restore proper draft and meet Nassau County code. The stainless steel resists the acid condensation that kills lesser materials, and we back every installation with our written guarantee.
Flexible Liner Solutions
Not every Manhasset chimney is straight. The corbelled offsets we find in pre-war Colonials and Tudors, especially in the older sections near Plandome Road, require a liner that can navigate bends without tearing or creating hang points for creosote. DuraFlex flexible liners handle up to 30-degree offsets while maintaining full structural integrity. We size these carefully - an oversized flexible liner in a too-large flue is as bad as no liner at all - and we verify the fit with our Level-2 camera before we seal the top. You’ll see the photos. We’ll explain what they show.
Liner Replacement & Liner Repair
Sometimes the clay tile liner is cracked but the surrounding masonry is sound. In those cases, a full replacement isn’t necessary. We can repair localized tile damage with HeatShield cerfractory foam, a refractory compound that fills cracks and restores a smooth, insulated flue surface. This works well in Manhasset chimneys where the thermal stress from fuel conversions - coal to oil to gas - has caused hairline fractures but not structural collapse. We’ll tell you honestly whether repair or replacement is the right path. No upsell.
Partial Rebuild & Full Chimney Rebuild
When the salt air off Manhasset Bay has done its worst, or when decades of deferred maintenance have left the stack structurally compromised, we rebuild. A partial rebuild addresses the top courses, the crown, and the flue walls above the roofline - common in Manhasset homes where the crown cracked and water infiltrated the brick freeze-thaw cycle. A full chimney rebuild strips the stack to the roofline or below and reconstructs with matching brick and proper flue sizing for your current appliance. We handle the Nassau County permit process, and we build to code, not to “good enough.”

Trusted Brands We Service in Manhasset
We don’t use builder-grade substitutes. Our trucks stock DuraFlex stainless and flexible liners, HeatShield cerfractory repair materials, and Gelco chimney caps and fittings - the brands specified by manufacturers who understand that a liner failure isn’t an inconvenience, it’s a house fire waiting to happen. For Manhasset customers, this means no waiting on special orders. When we arrive for your estimate, we can often show you the exact materials we’ll use, and in most cases, complete the installation same-day. Copperfield and Famco hardware round out our inventory for crown rebuilds, flashing repair, and custom cap fabrication when a standard size won’t fit your chimney’s profile.
Common Chimney Liner & Rebuild Problems We See in Manhasset Homes
- Cracked clay tile liners from fuel-switch thermal stress. Manhasset chimneys built for coal furnaces endured decades of high-temperature oil firing, then cooler gas appliance exhaust. Each conversion changed the thermal expansion pattern in the flue, and the clay tiles - never designed for cycling - cracked progressively. We find these with our Level-2 camera, show you the photos, and explain whether repair or replacement is warranted.
- Oversized flue passages causing improper draft and creosote buildup. A 12×12 flue designed for a coal furnace creates sluggish draft when connected to a 90,000 BTU gas boiler. The exhaust cools too quickly, condenses on flue walls, and mixes with residual soot to form glazed creosote. This is a code violation in Nassau County and a common reason Manhasset homes fail pre-sale inspections. We resize with a proper liner and seal the excess space.
- Spalled brick faces and eroded lime mortar from salt-laden bay air. Manhasset’s proximity to Manhasset Bay means persistent salt aerosol, especially in winter when storms drive spray inland. The salt crystallizes in brick pores, expands, and spalls the face. Lime mortar - softer than Portland cement, standard in pre-1950 construction - erodes faster under salt attack than in inland communities. We repoint with appropriate mortar mixes and rebuild when the damage is too extensive.
- Corbelled offsets trapping creosote and complicating inspections. The decorative and functional offsets in Manhasset’s older chimneys, built to clear rooflines or interior framing, create turbulence that deposits creosote and makes camera passage difficult. Our flexible liners navigate these offsets, and our cameras are sized to pass through and document conditions past the bend.

FAQs - Chimney Liner & Rebuild in Manhasset
Manhasset’s housing stock was built during the Gold Coast era when coal was the standard heating fuel, and those furnaces required large flue cross-sections to handle the volume of exhaust. When homeowners converted to oil and later to gas, the appliances shrank but the flues didn’t. A modern gas boiler might need a 6-inch round flue; it’s venting into a 12×12 inch masonry passage designed for a coal furnace. This mismatch causes poor draft, condensation, and creosote buildup, and Nassau County inspectors flag it during real-estate transactions. We relined a flue in a 1936 Tudor on Plandome Road originally sized for a coal furnace. The clay tile liner was cracked and the flue was 12×12 inches - far too large for the new gas boiler. We installed a 6-inch DuraFlex stainless steel liner and sealed the excess space with HeatShield, bringing the chimney up to code for the home’s sale. Call (855) 950-3861 if you’re facing a pre-sale inspection or your draft has been sluggish.
Manhasset’s location on Manhasset Bay exposes chimneys to persistent salt-laden air that accelerates spalling of brick faces and erosion of lime-based mortar joints, a faster deterioration cycle than inland Nassau County communities just a few miles south. For liner work, this means we often discover masonry damage during what starts as a simple relining job, and we address it before installing the new liner. A liner in a deteriorating shell won’t last. For rebuilds, we specify harder brick and appropriate mortar mixes when the original materials have succumbed to salt attack. Call (855) 950-3861 and we’ll assess whether your chimney’s exterior damage has compromised the flue structure.
Yes. Nassau County requires permits for chimney liner replacement and any structural rebuild work, and Manhasset falls under the Town of North Hempstead building department jurisdiction. We handle the permit application, the inspection scheduling, and the sign-off as part of our standard process. You won’t need to visit the building department or coordinate with inspectors. For most liner jobs, the permit is issued within a few business days; full rebuilds may require plan review. We’ll tell you the timeline upfront. Call (855) 950-3861 and we’ll walk you through what’s needed for your specific job.
We install DuraFlex stainless steel and flexible liners, and we repair with HeatShield cerfractory materials. These are professional-grade products, not the builder-grade substitutes some operators use. DuraFlex 316Ti is specified for condensing appliances and carries a lifetime warranty when installed by a certified technician. HeatShield is the only cerfractory foam approved for localized liner repair without full replacement. We stock these in our trucks for Manhasset jobs, so we’re not ordering and waiting. Call (855) 950-3861 to see the materials and get your estimate.
Most full rebuilds in Manhasset’s larger estate homes take 3 to 5 working days, assuming standard weather and no access complications. The height of these chimneys - often 30 feet or more on three-story Colonials and Tudors - plus the need to match existing brick and navigate corbelled offsets, extends the timeline compared to simpler structures. We work section by section, weatherproofing each night, and we don’t rush the mortar cure. If your home is on the market or you’re coordinating with other contractors, we’ll give you a firm schedule and stick to it. Call (855) 950-3861 to discuss timing for your project.
