Why Sterling Chimney Cleaning Bridgeport Is Selden’s Preferred Chimney Liner & Rebuild Company
More than 1,200 homeowners have trusted us with their chimneys, and that 4.7 average star rating across 1,234 verified reviews reflects the accountability that comes from having Gary Murphy handle jobs personally rather than dispatching rotating subcontractors. In Selden specifically, we’ve built repeat business through the neighborhood streets off Middle Country Road where oil-to-gas conversions clustered during the 2015–2022 period — homeowners there know we understand the oversized flue problem because we’ve solved it on their block already.
Our response time to Selden averages under two hours for emergency calls, and we carry DuraFlex and Copperfield stainless steel liner stock sized for the 6-inch retrofits these converted gas systems require. That’s the difference between a specialist who shows up with the right materials and a generalist who orders after measuring. Fourteen years, one trade — we don’t split your job between multiple contractors or refer out the rebuild portion.
Our Chimney Liner & Rebuild Services in Selden
Stainless Steel Liner Installation
For Selden’s converted gas systems, a 6-inch DuraFlex stainless steel liner is the fix we install most often. The original 8-inch clay flue in your 1960s Cape Cod or ranch was engineered for oil exhaust temperatures around 600°F; natural gas exhaust runs cooler and wetter, and that oversized flue lets acidic condensate cling to the walls instead of drafting out. We pull a flexible stainless liner through the existing flue, top it with a proper termination cap, and seal the connection at the appliance — typically completed in a single day for Selden homes with straightforward access.
Flexible Liner Retrofits
Not every Selden chimney runs straight. The split-levels near Hawkins Path and the older ranches with offset flues need a liner that navigates bends without losing draft performance. We use flexible stainless systems that conform to these irregular channels while maintaining the smooth interior surface that resists creosote buildup. For homes where the clay tile is intact but the flue is simply wrong-sized for gas, this is often the most cost-effective path — no masonry tear-out, just a properly sized passage for exhaust.
Liner Replacement
When clay tiles are cracked, spalled, or missing sections after fifty-plus winters of Long Island freeze-thaw, patching isn’t a permanent option. We extract the damaged liner where accessible and install a new stainless system that carries its own independent structural integrity — the new liner supports itself, so it’s not relying on deteriorating surrounding masonry. In Selden’s 1970s housing stock, we’re frequently called after a chimney inspection reveals tile shards in the cleanout or visible gaps in the flue wall that allow combustion gases into the home’s structure.
Partial Chimney Rebuild
Last winter we handled a partial chimney rebuild on a 1970s ranch off Boyle Road where the original clay tile liner had shattered after repeated freeze-thaw cycles. The homeowner had converted to natural gas two years prior, and the oversized flue was depositing corrosive soot on the interior walls. We installed a 6-inch DuraFlex stainless steel liner and rebuilt the crown with a reinforced mortar cap to prevent future spalling. That job is representative of what we see across Selden — the liner failure and crown deterioration are connected, and addressing only one leaves the other to fail next season.
Full Chimney Rebuild
When spalling brick, compromised structural courses, and multiple flue failures converge — often after years of water infiltration through a cracked crown — we rebuild from the roofline up. In Selden’s marine-influenced climate, where humidity from Long Island Sound and the Atlantic accelerates mortar erosion, we’ve reconstructed chimneys on homes near Coram and Centereach borders where the stack had simply reached end of service life. Gary Murphy scopes these jobs personally to determine what can be salvaged and what must come down, then rebuilds with proper crown overhang, cricket flashing where needed, and a new liner system sized for your current appliances.

Trusted Brands We Service in Selden
We install DuraFlex, HeatShield, and Copperfield — the materials professionals specify, not brands pulled off a retail shelf. For Selden homeowners, that means we stock liner diameters and lengths matched to the common flue configurations in this area’s post-war housing, so we’re not ordering parts and making you wait. When a liner job requires refractory repair or crown resurfacing, we use HeatShield’s cerfractory systems and Famco termination components that integrate properly with the stainless liner. Our supplier relationships let us source same-day when a Selden call reveals an unexpected flue dimension — another advantage of 14 years in a single trade, building inventory knowledge rather than scrambling.
Common Chimney Liner & Rebuild Problems We See in Selden Homes
- Oversized clay flues from oil-to-gas conversions. Selden sits within the Town of Brookhaven’s massive post-war suburban build-out, where thousands of 1960s–1970s Cape Cods and ranch homes were constructed with clay-tile-lined masonry chimneys sized for oil-fired heating systems. As Suffolk County homeowners have aggressively converted those oil boilers to natural gas or propane over the past decade, those oversized, unlined-for-gas flues now accumulate acidic condensate that rapidly deteriorates mortar joints and tile — making flue relining and chimney inspections a near-universal need on these streets rather than an occasional upsell.
- Cracked or missing clay tile sections from freeze-thaw damage. Central Suffolk County experiences repeated freeze-thaw cycles each winter, and nor’easters deliver heavy wet snow that saturates chimney crowns and mortar beds. After 50+ years of this cycling, Selden’s original clay liners show offset joints, vertical cracks, and missing sections that allow flue gases to leak into wall cavities or attic spaces — a genuine carbon monoxide risk that demands immediate attention.
- Deteriorated crowns and mortar beds from marine humidity. The marine-influenced humidity from both Long Island Sound to the north and the Atlantic to the south accelerates efflorescence and mortar erosion on exposed chimney stacks. We see this particularly on Selden homes where the crown was poured without proper slope or overhang, letting water pool and penetrate the masonry matrix below.
- Water infiltration accelerating liner failure. Once a crown cracks or mortar joints open, water follows gravity into the flue system, where it accelerates spalling of both brick and clay tile. In Selden’s converted-gas chimneys, this moisture combines with acidic condensate to create an especially aggressive deterioration environment — we’ve removed liner sections where the interior surface had degraded to powder.
Pricing for Chimney Liner & Rebuild in Selden, NY
Here’s what Selden homeowners can expect for typical chimney liner and rebuild work:
- Stainless steel liner retrofit (single flue, gas appliance): $2,800–$4,200
- Flexible liner with offset navigation: $3,200–$4,800

These ranges reflect Selden’s market and the typical access conditions in its 1960s–1980s single-family stock. Factors that move a job toward the higher end: multiple flues requiring separate liners, significant mortar deterioration requiring more extensive rebuild, steep roof pitch complicating access, and the need for custom termination hardware. We provide exact quotes after inspection — call (888) 975-6389 to schedule. Estimates are free, and we don’t charge for the diagnostic visit that determines whether you’re facing a liner job or something more extensive.

FAQs — Chimney Liner & Rebuild in Selden
The existing 8-inch clay flue in your Selden home was sized for oil exhaust at roughly 600°F; natural gas exhaust is cooler and produces more water vapor, and that oversized flue lets acidic condensate accumulate on the walls instead of drafting properly. When a Selden homeowner converts from oil to gas, the existing 8-inch clay flue is drastically oversized for the new appliance’s cooler exhaust, causing persistent sooting and water damage inside the flue — a pattern technicians see repeatedly on the neighborhood streets off Middle Country Road and Boyle Road, where the oil-to-gas conversion wave hit hardest in the 2015–2022 period. A 6-inch stainless steel liner corrects the sizing and contains the exhaust safely. Call (888) 975-6389 and Gary Murphy can inspect your flue to confirm whether conversion damage has already begun.
Annual inspection is the standard for active heating-system flues in Selden’s climate, and we recommend adding a mid-winter check after severe nor’easters. Central Suffolk County experiences repeated freeze-thaw cycles each winter, and nor’easters deliver heavy wet snow that saturates chimney crowns and mortar beds; the resulting spalling and cracked crowns are the leading repair driver on these homes. If your home still has original clay tile from the 1960s or 1970s, that schedule isn’t conservative — it’s necessary. Call (888) 975-6389 to book an inspection before the next freeze cycle.
Individual clay tile replacement is rarely practical in Selden’s aging chimneys because the surrounding mortar is typically deteriorated and accessing specific tiles without damaging adjacent courses is difficult. We usually recommend a stainless steel liner system that installs within the existing flue without requiring full masonry demolition, paired with crown repair or partial rebuild as needed. A full rebuild becomes necessary when structural courses are compromised or multiple flues have failed simultaneously. Gary Murphy evaluates each Selden chimney personally to determine the least invasive solution that still meets safety standards. Call (888) 975-6389 for an assessment.
We install DuraFlex and Copperfield stainless steel liners as our primary systems for Selden’s gas-conversion retrofits, with HeatShield cerfractory products for crown and refractory repairs where needed. These are brands specified by chimney professionals, not carried by big-box retailers, and we stock the 6-inch diameters most common for Selden’s converted heating systems. Our supplier relationships with Famco and Olympia Chimney also let us source termination caps and connection hardware matched to local appliance configurations. Call (888) 975-6389 to confirm material availability for your specific flue dimensions.
Retrofitting makes sense if you plan to use the fireplace for supplemental heating or if the open flue is creating drafts that affect your home’s energy efficiency; an unlined fireplace flue in a Selden Cape Cod also presents a fire risk if creosote from occasional use ignites. Many Selden homes have two-flue chimneys where the heating-appliance flue was converted but the fireplace flue was ignored — that second flue still needs proper lining if it’s ever used, and sealing it properly if it’s permanently retired. We can line it with a stainless system or install a proper cap and seal depending on your plans. Call (888) 975-6389 and we’ll walk through whether the investment fits your use case.
