We’ve been working on chimneys in Plainview since 1984. We know the 1950s Cape Cods off Manetto Hill Road, the split-levels near the Plainview-Old Bethpage Community Park, and the raised ranches along South Oyster Bay Road. These houses share something important: original masonry chimneys built for oil heat, now sixty to seventy years old, often serving gas appliances they were never designed for. That mismatch between old flue and new fuel is the root of most liner failures we see here. When your clay tiles crack or your stainless liner corrodes prematurely, you want someone who understands why it happened, not just how to patch it.

Our Chimney Liner & Rebuild Services in Plainview
Stainless Steel Liner Installation
Stainless steel liners are the standard for gas conversions in Plainview’s mid-century homes. The original clay tile flues were sized for oil-burning appliances with higher exhaust temperatures. When homeowners switched to gas in the 1980s and 1990s, those oversized masonry flues became cold surfaces where moisture and acids condense. A properly sized stainless liner - we use DuraFlex and Olympia Chimney products - creates the correct draft and protects the masonry from corrosive condensation. In Plainview’s damp climate, with humidity from Long Island Sound and the Atlantic keeping masonry chronically moist, this matters more than it does inland. Last winter on Alderwood Lane, we relined a 1958 raised ranch where the original clay tile liner had cracked from decades of oil-to-gas conversion moisture. After removing the old tiles, we installed a DuraFlex stainless steel liner and added a Gelco crown extension to fix a chronic downdraft caused by the garage roofline clearance issue - permanent fix, no more smoky mornings.
Flexible Liner Installation
Some Plainview chimneys have offsets or bends that rigid liners cannot navigate, particularly in split-levels where the flue path shifts between floors. Flexible liners solve this without dismantling walls. We size them precisely for the appliance - critical because an oversized flexible liner in a gas application creates the same condensation problems as an oversized masonry flue. Our Chimney Liner & Rebuild team measures twice and installs once.
Liner Replacement
Not every failed liner needs a full rebuild. Sometimes the masonry is sound and only the liner itself has deteriorated. We see this in Plainview homes where a previous installer used the wrong material for the fuel type, or where a DIY liner kit was sized incorrectly. We remove the damaged liner, inspect the surrounding masonry with our camera, and install a replacement that matches the appliance and the fuel. If the masonry shows hidden damage, we tell you before we proceed - no surprises on the bill.
Partial Chimney Rebuild
Freeze-thaw spalling in exposed chimney crowns and brick along Plainview’s damp Long Island climate causes water entry that deteriorates mortar joints. A partial rebuild addresses the damaged section - often the crown and upper courses - while preserving sound masonry below. But partial rebuilds fail if the root cause is not fixed. In Plainview’s 1950s-60s split-levels and ranches, the short, low-pitch roofline over the garage wing often leaves the chimney crown too close to the flue opening, causing downdrafts and debris accumulation that Nassau County code may require correcting with a cap or crown extension. We rebuild with matching brick and proper crown sealing, then verify clearance to code. Done right - and we stand behind it.

Trusted Brands We Service in Plainview
We stock professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - no builder-grade substitutes. For Plainview homeowners, this means faster turnaround because we are not waiting on special orders. When we find a cracked crown on a Saturday morning in January, we have the Gelco cap or HeatShield cerfractory sealant on the truck. We also work with Famco and Copperfield components for specialized applications. These are the brands specified by manufacturers who understand that a liner in a 1962 Plainview ranch faces different stresses than one in a new construction.
Common Chimney Liner & Rebuild Problems We See in Plainview Homes
- Oversized flues from oil-to-gas conversion. The original masonry flue was built for an oil boiler. Gas exhaust is cooler and wetter. Without a properly sized liner, that cold surface accelerates creosote buildup and flue gas condensation, leading to rapid steel liner corrosion if the replacement is not sized correctly for the gas appliance.
- Freeze-thaw spalling in crowns and brick. Plainview’s damp Long Island climate, with residual humidity from surrounding water bodies, keeps masonry chronically moist. Sustained below-freezing winter stretches drive freeze-thaw cycles that spall brick and crumble mortar in chimneys already sixty to seventy years old.
- Downdraft misdiagnosed as liner failure. Homeowners mistake downdraft symptoms for a draft problem and attempt DIY fixes that fail to meet Nassau County height-clearance code. The real issue is often the low garage roofline common to Plainview split-levels, requiring crown extension or chimney cap retrofits rather than simple liner replacement.
- Cracked clay tiles from thermal shock. Original clay tile liners in Plainview’s post-war housing stock were never designed for the rapid temperature swings of modern high-efficiency appliances. Decades of cycling causes vertical cracks that allow flue gases into the masonry - a fire hazard and a carbon monoxide risk.

FAQs - Chimney Liner & Rebuild in Plainview
Yes. Gas exhaust is cooler and more acidic than oil exhaust, and your oversized masonry flue will condense moisture that destroys both the flue and the appliance. We install a properly sized stainless steel liner - typically DuraFlex or Olympia Chimney - sized specifically for your new gas appliance. Call (855) 950-3861 and we will measure it during your free estimate.
No, and it is likely not a liner problem at all. In Plainview’s 1950s-60s split-levels, the short garage roofline often leaves the chimney crown too close to the flue opening, causing downdrafts that blow debris back down. Nassau County code may require a crown extension or proper chimney cap to fix the clearance. We see this pattern constantly in homes near Fairfield Drive and across the 11803 zip code. Call us - we will verify the height and give you a permanent solution, not another temporary screen.
The masonry tells the story. During our Level-2 camera inspection, we photograph the flue interior and the exterior brick and crown. If the clay tiles are cracked but the mortar joints and brick are sound, a liner replacement suffices. If we find spalled brick, crumbling mortar, or a cracked crown with water staining inside the flue, the masonry itself is failing and a partial rebuild is necessary - installing a new liner in deteriorated masonry wastes your money. We show you the photos and explain which category you are in. No pressure, just facts.
We match as closely as brick aging allows. Plainview’s post-war housing stock used common regional brick from the 1950s-60s that we can source through our suppliers. Weathering over sixty years means new brick will not be identical, but we select for compatible size, texture, and color range, then blend the courses so the repair does not shout. We have done this on homes from Manetto Hill to South Oyster Bay Road - the results hold up.
A properly installed DuraFlex stainless steel liner, correctly sized for the appliance and fuel type, should last 15 to 20 years in Plainview’s climate. Premature failure usually means incorrect sizing (oversized for gas), poor installation (gaps at connections), or neglected maintenance (annual cleaning ignored). We document the installation details and schedule reminders so you get the full lifespan. If your DuraFlex liner is failing early, we will diagnose why - not just replace it again.
