Fast, Reliable Chimney Liner & Rebuild Across Selden
Chimney liner replacement and rebuild work in Selden typically runs $2,800–$7,500 depending on flue size, liner type, and whether the chimney structure itself needs partial rebuilding. Most Selden jobs are completed in one to two days, with our crew crossing the Sound to reach 11784 within 90 minutes of a call. We’ve been working Suffolk County’s legacy oil-heat belt long enough to recognize the sound of spalling clay tile before we even set up the ladder.
Selden’s ranch and split-level neighborhoods off College Road and Middle Country Road are filled with chimneys built for 1960s oil boilers, not the gas inserts and wood stoves homeowners have added since. That’s why our Chimney Liner & Rebuild team treats every Selden inspection as a potential liner replacement until proven otherwise. Acid-etched clay tile, freeze-thaw damage, and oil-to-gas conversion mismatches are the standard findings here, not the exception. Call (833) 719-7193 for a free estimate.
Why Premier Chimney Cleaning Connecticut Is Selden’s Preferred Chimney Liner & Rebuild Company
Eight years, one specialty — and a lot of those years spent on Long Island’s North Shore and Suffolk County interior. Anthony Perez leads every job personally, which means Selden homeowners get the owner on the roof, not a subcontractor learning the trade on their chimney. After 800+ reviews averaging 4.7 stars, we’ve earned the kind of reputation that travels by word-of-mouth across the Sound from Bridgeport to Selden.
Our response time to Selden averages under 90 minutes because we know the route: I-95 to the Throgs Neck or Whitestone, then straight out the LIE to Exit 63. We’ve worked the Cape Cods near Dawn Drive, the ranches off Old Town Road, and the split-levels clustered around the Selden Plaza corridor. That familiarity matters when you’re diagnosing a chimney that’s been deteriorating since the Johnson administration.
Selden customers specifically mention our thoroughness in reviews — the fact that we photograph the flue interior, explain the oil-to-gas conversion code issues in plain English, and don’t push rebuilds when a liner replacement solves the problem. Anthony’s accountability as both owner and lead technician means the person who quotes the job is the person who does the job.
Our Chimney Liner & Rebuild Services in Selden
Stainless Steel Liner Installation
For Selden’s oil-damaged flues, we install rigid or flexible stainless steel liners using DuraFlex and Olympia Chimney products sized precisely to your appliance. A 1960s clay tile liner built for a 172,000 BTU oil boiler is almost always oversized for a modern 40,000 BTU gas insert — and that size mismatch creates condensation, corrosion, and carbon monoxide hazards. We measure the flue, measure the appliance, and specify the right liner diameter to meet Town of Brookhaven code.
On a ranch off College Road, we pulled an original clay tile liner that had been silently spalling for years from oil combustion byproducts. Our crew installed a DuraFlex stainless steel flexible liner sized for the homeowner’s new gas insert, correcting a dangerous undersized opening left by the previous oil-to-gas conversion. The job was complicated by late-winter freeze-thaw—typical for Selden—so we used a heat gun to seat the top plate before the next nor’easter.
Flexible Liner Installation
Flexible liners are our go-to for Selden’s older masonry chimneys with offset flues or tight cleanout passages. The Cape Cods and ranches built during the 1965–1975 boom often have chimney structures with slight shifts or settled offsets that make rigid stainless steel impossible to feed. We use DuraFlex flexible liners with proper top plates and rain caps, never the cut-rate hardware-store kits that crack at the flex points after two seasons.
The flexibility also helps us navigate around the spalled tile fragments that litter so many Selden flues — remnants of decades of sulfuric acid etching from oil combustion. We extract what we can, smooth the passage, and install the flexible liner with proper insulation to prevent condensation in the oversized flue chamber.
Liner Replacement
Full liner replacement is the most common service we perform in 11784, and it’s rarely optional by the time we arrive. The original clay tile in Selden’s 1960s–70s housing stock was never designed for the acidic exhaust of modern condensing appliances, and decades of oil heat have turned what looks like intact tile into a honeycomb of cracks and spalls. We remove the damaged liner — sometimes in pieces, sometimes as powder — and install a new stainless steel system from top to bottom.
Cost for a typical Selden liner replacement runs $3,200–$5,800 for a single-flue chimney, including the liner, insulation, top plate, cap, and proper appliance connection. Homes with multiple flues or significant offset complexity push toward the higher end.
Partial Chimney Rebuild
When freeze-thaw cycles have compromised the masonry above the roofline, a liner replacement alone won’t solve the problem. We see this regularly on Selden’s south-facing chimney exposures, where daily sun-thaw and overnight re-freeze open mortar joints faster than the north side. Our partial rebuilds address the crown, top courses of brick, and sometimes the shoulder of the chimney — restoring structural integrity before the new liner goes in.
A partial rebuild in Selden typically adds $1,800–$3,500 to the project, depending on course count and whether we need to reconstruct the crown with proper slope and drip edge. We use HeatShield crown sealant and proper Portland-based mixes, not the acrylic caulk jobs that fail within two winters.

Trusted Brands We Service in Selden
We stock DuraFlex flexible liners, Olympia Chimney rigid systems, and HeatShield resurfacing products for Selden jobs — no waiting on drop-shipments from Midwest warehouses. When Anthony quotes your job, he’s specifying materials he’s personally installed hundreds of times, not reading from a distributor catalog. For crown and masonry work, we use Copperfield refractory products and Famco chimney caps, the same brands specified by chimney professionals nationwide. That local inventory means a Selden homeowner who calls Monday can often have Anthony on the roof by Wednesday with everything needed to complete the job.
Common Chimney Liner & Rebuild Problems We See in Selden Homes
- Oil-to-gas conversion mismatches. Homeowners who convert from oil to gas assume the old oversized, acid-damaged clay tile liner is safe for gas, but the liner is usually the wrong size and condition, leading to flue gases backing up into living spaces. We inspect the flue diameter against the appliance BTU rating and find code violations in roughly two-thirds of Selden conversions.
- Freeze-thaw masonry collapse. Repeated nor’easter freeze-thaw cycles drive moisture into already spalled mortar joints, causing partial chimney collapses that require a partial rebuild before a new liner can be installed. The damage accelerates dramatically after the first visible crack appears.
- DIY liner installations flagged at sale. DIY or unlicensed chimney crews install flexible liners without resealing the crown or correcting the flue size, resulting in code violations during Town of Brookhaven real-estate inspections. We’ve re-done five of these in Selden in the past two years alone.
- Spalled tile misdiagnosed as “just dirty.” Homeowners see black staining and assume creosote buildup, but in Selden’s oil-heat legacy housing, that blackening is often sulfur-compound corrosion eating the tile face. A camera inspection separates dirty from damaged — and the difference determines whether sweeping or replacement is needed.

FAQs — Chimney Liner & Rebuild in Selden
Almost certainly yes — and it’s a safety issue, not a recommendation. The original clay tile liner in your Selden home was sized for a high-temperature, high-volume oil exhaust, and decades of sulfuric acid exposure have likely spalled the interior surface. A gas appliance in that same flue will produce cooler, wetter exhaust that condenses on the oversized, damaged surface, accelerating corrosion and risking carbon monoxide leakage. We inspect these conversions weekly in 11784 and find code-deficient liners in roughly two-thirds of cases. Call (833) 719-7193 for a camera inspection — estimates are free.
A rigid liner offers slightly better draft performance and longevity but requires a straight flue path; a flexible liner navigates offsets and settled masonry but needs proper insulation to prevent condensation. Your Selden Cape Cod likely has a straight or near-straight flue if it was built in the 1960s–70s, making rigid a viable option, but settling over 50+ years sometimes creates offsets we discover during inspection. Anthony will camera the flue and recommend based on what your specific chimney allows — not a one-size-fits-all default. Call (833) 719-7193 to schedule the inspection.
It directly affects your liner — and it’s never just cosmetic in Selden’s climate. The moss and efflorescence you see indicate moisture penetration, and that moisture freezes, expands, and drives deeper into the crown and flue walls with every nor’easter cycle. A compromised crown lets water pool on the liner top plate, rust the connection, and seep between the liner and masonry, accelerating spalling of whatever original clay tile remains. We treat crown condition as part of every liner inspection in Suffolk County. Call (833) 719-7193 and we’ll assess whether sealant or rebuild is needed.
No — and attempting to do so violates Town of Brookhaven fire code and creates a genuine house-fire risk. Your Selden chimney’s original clay tile liner, even if intact, was sized for an oil boiler or fireplace, not the concentrated high heat and specific draft requirements of a wood stove insert. An unlined or improperly lined wood stove overfires the surrounding masonry and can ignite creosote deposits in the oversized flue chamber. We install insulated stainless steel liners specifically sized to the stove’s outlet diameter — typically 6″ or 8″ — with proper clearance to combustibles. Call (833) 719-7193 for a quote on safe insert installation.
You can’t tell from the hearth — and neither can we without a camera. Spalling clay tile and heavy creosote buildup both appear as blackened, irregular surfaces to the naked eye from below. Our chimney camera inspection reveals the difference: spalling shows as flaked, pitted, or missing tile sections with the clay body exposed; creosote shows as layered, tarry deposits on an intact surface. In Selden’s oil-heat legacy housing, we often find both — the sulfur corrosion weakened the tile, and subsequent use filled the cracks with creosote. The camera inspection is $149, credited toward any work. Call (833) 719-7193 to schedule with Anthony.
