Centereach sits at the heart of Suffolk County’s 11720 ZIP, a community built fast during Long Island’s suburban boom between the mid-1950s and mid-1970s. Those decades produced solid, unpretentious homes - ranches along Mark Tree Road, Cape Cods near Dawn Drive, split-levels off Nichols Road - and nearly all of them were fitted with oil-fired boilers venting through original clay-tile flues. That history matters when we’re sizing a liner or deciding whether mortar joints can be saved. The chimney on a 1962 ranch in Centereach isn’t like a chimney in a 1990s development or a prewar city rowhouse. We’ve worked on enough of them to know the difference before we unload the truck.
Our Chimney Liner & Rebuild in Centereach crew carries Level-2 camera equipment, stainless steel liners from DuraFlex and Olympia Chimney, and the permits required by the Town of Brookhaven. Most calls from Centereach reach us within 30 minutes during business hours, and we schedule inspections within a day or two.
Why Hearthstone Chimney Co. Is Centereach’s Preferred Chimney Liner & Rebuild Company
We’ve been serving Suffolk County homeowners for over 42 years, and Centereach has been part of our route since the beginning. The same families call us back. Their neighbors call after seeing our trucks on the block. We don’t run ads claiming to be “the best” - we let the work speak, and we stand behind it with the 90-Day Done Right Promise in writing.
Our Centereach customers tend to be longtime homeowners, often 55 to 75, who bought their house in the 1980s or 1990s and raised a family there. They’ve seen contractors come and go. They remember the ones who showed up late, left a mess, or charged more than the estimate. We answer the phone with a live person, 24/7, because we know these homeowners would rather talk to a human than navigate a website. Our technicians are background-checked and uniformed. Most jobs finish in one visit. The price we quote is the price on the invoice - no surprises, no “we found something else” add-ons after the work starts.
What separates us from the one-truck operators and the national chains is documentation. Every Level-2 inspection ends with photos you can see on a screen and a plain-English verdict: this flue is cracked here, this crown is spalled there, this liner is oversized for your new gas boiler and here’s why that matters. We explain it like a craftsman, not a salesman. Then we write it up, and if you hire us, we back it with the 90-Day Done Right Promise - Krafted right, Every time, Your home first, Standing behind it. If it’s not right, we come back. No paperwork to dig up, no argument.
Our Chimney Liner & Rebuild Services in Centereach
Stainless Steel Liner Installation
A stainless steel liner is the standard correction for Centereach’s original clay-tile flues that have cracked or been left improperly sized after a heating conversion. The Town of Brookhaven requires a permit for this work, which we pull as part of the job. We use DuraFlex and Olympia Chimney stainless products, sized precisely to your appliance’s BTU output and venting requirements. A typical stainless steel liner installation in Centereach runs $2,200-$3,800, depending on flue height, diameter, and whether the existing clay needs extraction.
Flexible Liner Installation
Some of Centereach’s older masonry chimneys - especially the offset flues common in 1960s split-levels near Hawkins Path - won’t accept a rigid liner without extensive demolition. A flexible liner navigates those offsets while still providing a sealed, properly sized venting path. We see this need frequently in homes where a previous owner converted from oil to gas without updating the flue. Flexible liner jobs in Centereach typically cost $1,800-$3,200.
Liner Replacement
When an existing stainless or clay liner has failed but the surrounding masonry is sound, replacement is the targeted fix. In Centereach’s 11720 ZIP, we often find that a liner installed 15-20 years ago by another company was the wrong alloy or wrong diameter for the appliance. We remove it, inspect the surrounding structure with our camera, and install a replacement that matches current NFPA 211 standards. Liner replacement in Centereach generally falls between $2,000 and $3,500.
Partial Chimney Rebuild
Centereach’s maritime humidity - pulled in from Long Island Sound and the Atlantic - accelerates freeze-thaw damage at chimney crowns and upper courses of brick. When the upper third of a chimney is deteriorated but the lower structure is solid, a partial rebuild restores integrity without the cost of full demolition. We match existing brick and mortar where possible, and we always install proper crown flashing to slow future water intrusion. Partial rebuilds in Centereach typically range from $3,500 to $6,000.
Our Chimney Liner & Rebuild team also handles full rebuilds when the damage extends below the roofline, though we always inspect first to determine whether a less invasive solution will suffice. We also offer Chimney Repair in Centereach for crown work, repointing, and flashing - sometimes that’s all a chimney needs.

For liner work in Centereach, we stock and install professional-grade materials from HeatShield, Gelco, and Famco, alongside DuraFlex and Olympia Chimney stainless products. HeatShield’s cerfractory resurfacing system lets us restore some clay flues that would otherwise require full replacement - a square deal for homeowners whose chimneys are structurally sound but have internal spalling.

We keep common sizes in stock, so most Centereach jobs don’t wait on parts.
Common Chimney Liner & Rebuild Problems We See in Centereach Homes
- Oversized flues after oil-to-gas conversion. Original 8×8-inch or larger terra cotta liners in Centereach were built for oil boilers. When a homeowner switches to natural gas or propane without resizing the flue, condensation pools inside the oversized space, producing acidic runoff that attacks mortar and creates carbon monoxide risk. Town of Brookhaven code requires a properly sized liner; many homeowners don’t realize their conversion triggered this obligation.
- Freeze-thaw crown failure. Centereach’s mid-island location means winter temperatures swing across the freezing mark repeatedly, especially during January and February thaws. Water penetrates crown cracks, expands when it freezes, and opens the crack wider each cycle. By March, we’re scheduling crown rebuilds across the 11720 ZIP.
- Sulfurous mortar deterioration in oil-heat chimneys. Long Island’s oil-heat concentration produces a different kind of chimney damage than wood-burning regions. The acidic soot from oil combustion attacks mortar joints from the inside out, especially in chimneys that haven’t been regularly swept. We also handle Chimney Cleaning & Sweep in Centereach to catch this before rebuild-level damage sets in.
- Improper gas appliance venting into unlined flues. This is the dangerous one. We’ve found gas water heaters and boilers in Centereach split-levels venting directly into crumbling clay flues with no liner at all - a code violation and a lethal hazard. Our Level-2 camera inspection finds it, and we document it with photos you can see.
