Fast, Reliable Chimney Liner & Rebuild Across Selden
Chimney liner installation and rebuild work in Selden typically runs $2,800-$8,500 depending on whether we’re relining a single flue or rebuilding from the roofline up, and our Chimney Liner & Rebuild crews complete most Selden jobs in one day. We’ve been driving to homes off Bicycle Path and North Bicycle Path since 1984, and we know the 11784 area well enough to spot the patterns before we even unload our tools. Selden’s ranch and cape cod stock from the 1960s and 70s keeps us busy with clay tile liners that have finally given out after fifty-plus years of oil heat, freeze-thaw cycles, and the occasional nor’easter driving salt air inland from the Sound. If your chimney is pulling double duty after a fuel conversion, or if you’ve noticed bits of terra cotta in your cleanout, call (844) 803-1545. A live person answers, 24 hours a day.
Why Hearthstone Chimney Co. Is Selden’s Preferred Chimney Liner & Rebuild Company
We’ve worked in Selden long enough to remember when much of this area was still potato fields and scrub oak. That history matters because we understand how the Town of Brookhaven’s suburban boom produced thousands of homes with masonry chimneys sized for oil-fired systems, many of which now sit unlined or improperly lined after conversions to gas or wood inserts. Our Chimney Repair in Selden starts with Level-2 camera inspections that end with photos you can see and a plain-English verdict, documented like an engineer, explained like a craftsman.
Selden homeowners call us back because we show up when we say we will, we explain what we found without talking down, and we put our Fireplace Services in Selden behind the 90-Day Done Right Promise in writing with no arguing. Background-checked, uniformed technicians complete most jobs in a single visit, and the price we quote is the price on the invoice. No surprises on the bill.
Our office is staffed by a live person every hour of every day, not a callback queue. When a chimney issue has you worried, you reach someone who can actually dispatch help to Selden, not a recording that promises a response within 48 hours.
Our Chimney Liner & Rebuild Services in Selden
Stainless Steel Liner Installation
A stainless steel liner is the right fix for most Selden chimneys that have deteriorated clay tile but sound masonry walls. We size the liner to the appliance, not the existing flue, which matters enormously in this town because so many original chimneys were built oversized for oil boilers. A properly sized stainless liner from DuraFlex or Olympia Chimney improves draft, reduces condensation, and brings an aging flue up to modern safety standards. Most Selden installations we do off Old Town Road and Hawkins Road run $2,800-$4,200 for a single-flue system, completed in one day with no mess left behind.
Flexible Liner Installation
Selden’s 1960s ranches often have chimney offsets or bends that make rigid stainless tubing impossible to feed. A flexible liner navigates those turns while still providing the same venting protection. We see this need frequently in the cape cods near Selden Plaza, where chimney runs were built with offsets to clear second-floor framing. Flexible installations typically fall in the $3,200-$4,800 range in Selden, depending on length and diameter. We pull the permit, we handle the inspection, and we leave you with documentation for your records.
Liner Replacement
Sometimes a previous liner has failed due to improper sizing, poor installation, or material that couldn’t handle the appliance it was paired with. In Selden, we regularly find chimneys where a flexible liner was jammed into an oil-flue without proper sizing for a later gas conversion, leading to condensation damage and creosote buildup. We remove the failed liner, inspect the masonry with our camera, and install a replacement sized correctly for what you’re actually burning now. Replacement jobs in Selden generally run $3,500-$5,500.
Partial Chimney Rebuild
Central Long Island’s freeze-thaw cycles hit hard above the roofline, and Selden chimneys from the 70s often show spalled brick, failed crowns, and mortar joints that have turned to sand. When the upper portion is compromised but the structure below is sound, a partial rebuild makes sense. We rebuild from the roofline up using matching brick where possible, pour a new concrete crown with proper overhang and drip edge, and install our Chimney Cap & Crown in Selden from Famco or Copperfield to protect the investment. Partial rebuilds in Selden typically range from $4,500-$7,500 depending on height and accessibility.

Trusted Brands We Service in Selden
We don’t use builder-grade substitutes. Our Selden trucks carry professional-grade materials from Olympia Chimney, Famco, and Copperfield, plus DuraFlex flexible liner systems when the job calls for them. That inventory on the truck means we don’t waste your time with supply runs. Most Selden homeowners we serve have never heard of these brands, and that’s fine, they shouldn’t have to. What matters is that these are the same materials specified by chimney engineers and required by warranty underwriters, not the cut-rate alternatives that some operators install to win on price. We buy right, we install right, and we stand behind it with the 90-Day Done Right Promise, in writing, no arguing.
Common Chimney Liner & Rebuild Problems We See in Selden Homes
- Oil-to-gas conversions without relining. Selden’s housing boom produced chimneys sized for 180-degree oil exhaust, not the cooler, wetter flue gases from high-efficiency gas appliances. We regularly find gas boilers and water heaters venting into unlined or oversized flues near Independence Plaza and along the Middle Country Road corridor, creating condensation that destroys mortar from the inside out.
- Clay tile liner collapse after decades of thermal cycling. The original terra cotta flue tiles in Selden’s 1960s and 70s construction were never designed for sixty years of service. We’ve pulled fragments of collapsed liner that were blocking the flue and forcing exhaust into the chimney walls, a condition that often shows no symptoms until a Level-2 inspection catches it.
- Freeze-thaw damage to chimney crowns and upper masonry. Selden sits far enough inland that homeowners sometimes assume salt air isn’t a factor, but prevailing winds carry enough marine moisture to accelerate spalling and mortar deterioration. Combined with Brookhaven’s hard freeze cycles, this produces the cracked crowns and missing brick faces we see on roofs throughout 11784.
- Improperly sized inserts stuffed into unlined fireplaces. Wood-burning inserts are popular in Selden’s older homes, but without a proper liner connecting the insert to the top of the chimney, creosote deposits in the remaining flue space create a fire hazard. We install insulated stainless connectors that maintain proper clearances and meet NFPA 211 requirements.
