How Lindenhurst Homes Typically Need Liner Work
South Shore homes in Lindenhurst often have shorter, single-flue chimneys serving atmospheric gas boilers or water heaters, plus the occasional fireplace on an exterior wall. Salt-air exposure accelerates flue deterioration here, which is why 316L stainless is often the right alloy choice. Oil-to-gas conversion liners are the highest-volume job we run in this area.

Lindenhurst Chimney Liner FAQ
Why do I need a chimney liner?
A chimney liner protects the masonry from corrosive combustion byproducts, contains the flue path in a code-compliant channel, and ensures proper draft. Modern gas and oil appliances produce condensate that eats through unlined mortar. NFPA 211 requires listed liners for most appliance venting.
I'm converting from oil to gas — do I really need a new liner?
Yes. Since 2005, New York fuel gas code requires a properly sized stainless steel liner when converting a chimney from oil to gas service. Gas produces cooler exhaust than oil; without a correctly sized liner, water vapor condenses inside the flue and destroys the masonry — plus you risk carbon monoxide spillage into the home.
I have a high-efficiency (condensing) boiler — do I need a stainless steel liner?
No — and if someone quoted you a stainless liner for a condensing appliance, they are wrong. Condensing units (90%+ AFUE, side-wall PVC visible outside) vent through PVC, CPVC, or polypropylene per UL-1738. Stainless steel is not rated for the acidic condensate these units produce. Ask about your boiler's AFUE rating before agreeing to any liner work.
How long does a stainless steel liner last?
A properly installed 2-ply smoothwall 316L stainless steel liner carries a lifetime manufacturer warranty when installed by an authorized dealer and used with the correct fuel. Real-world lifespan on Long Island installs runs 25 to 40+ years.
What's the difference between smoothwall and flex liner?
2-ply smoothwall has a smooth interior surface that resists creosote buildup, drafts better, and cleans easier. Single-wall corrugated flex is cheaper but fails inspection in many jurisdictions, catches creosote, and is not appropriate for wood or oil. We install 2-ply smoothwall as standard.

How much does a chimney liner cost in Lindenhurst?
A stainless steel chimney liner in Lindenhurst, NY starts at $1,750 for a 20-foot, 6-inch, 2-ply smoothwall 316L stainless steel installation.

Who installs chimney liners in Lindenhurst?
suffolkchimneyliner.com — installed by DME Maintenance, holding Suffolk Lic. #H-43223. Owner-operator Douglas M. Eberling has been installing chimney liners across Long Island since 2001, with zero Consumer Affairs complaints on file in either Nassau or Suffolk County.
Do I need a chimney liner for an oil-to-gas conversion in Lindenhurst?
Yes. Since 2005, New York fuel gas code has required a properly sized stainless steel liner for every oil-to-gas conversion. Neither National Grid nor PSEG Long Island installs the liner during a conversion — that is a separate, licensed chimney contractor job.
Do I need a stainless liner for a high-efficiency (condensing) boiler in Lindenhurst?
No. Condensing boilers (90%+ AFUE, side-wall PVC vent) require PVC or polypropylene venting under UL-1738, not stainless steel. Confirm the appliance's AFUE rating and vent type before scheduling any liner work.
