We’re familiar with the streets off Middle Country Road, the ranch rows near Boyle Road, and the Cape Cod clusters around Hawkins Road — the same 1960s and 1970s homes that dominate Selden’s 11784 zip code. Gary Murphy, our owner and lead technician, has spent 14 years in the chimney trade, and he’s personally handled hundreds of jobs in central Suffolk County. That matters here because Selden chimneys aren’t generic. They’re aging clay-tile systems originally sized for oil heat, now frequently mismatched to gas conversions that changed the exhaust chemistry entirely. When you hire Sterling Chimney Cleaning, you’re getting someone who recognizes that pattern before the camera even goes up the flue.
Why Sterling Chimney Cleaning Bridgeport Is Selden’s Preferred Chimney Cleaning & Sweep Company
More than 1,200 homeowners have trusted us with their chimneys, and our 4.7 average star rating across 1,234 verified reviews reflects the accountability that comes from owner-led work. Gary handles it personally — he’s the technician who arrives at your Selden home, runs the inspection, and explains what he’s seeing.
Our response time to Selden is typically same-day or next-day during peak season, and we don’t route you through a call center or dispatch a rotating crew. We’ve worked on chimney systems in the neighborhoods near Selden Plaza, along the stretch of Middle Country Road toward Centereach, and throughout the residential blocks between Mooney Pond Road and College Road. That local repetition means we know which builders used which clay tile specs, where the freeze-thaw damage tends to concentrate, and how the coastal humidity from Long Island Sound and the Atlantic accelerates mortar erosion on exposed stacks.
Our Chimney Cleaning & Sweep team doesn’t subcontract out inspections or relining work. From your first sweep to a full rebuild, one call covers it.
Our Chimney Cleaning & Sweep Services in Selden
Level 1 Inspection
A Level 1 inspection in Selden is the baseline annual service for homeowners who haven’t changed their heating system or experienced any chimney event. We examine the readily accessible portions of your chimney exterior, interior, and connection — checking for creosote buildup, obstructions, and basic structural soundness. For Selden’s 1960s-era Cape Cods with original decorative fireplaces, this annual check often reveals the first signs of crown cracking or flue tile shifting before water infiltration becomes visible inside the home. The service typically runs $180–$250.
Level 2 Inspection
Level 2 inspections are where our Selden work gets specific. We use a video camera to scan the full length of the flue liner, documenting every crack, spall, and mortar gap. In Selden, this is non-negotiable after any oil-to-gas conversion — the oversized 8-inch clay flue that worked fine for oil heat is now drastically wrong for gas, and the cooler exhaust condenses acidic moisture against the tile walls. Last winter, we serviced a 1972 ranch on a street off Boyle Road where the homeowner had converted from oil to gas three years prior. During a Level 2 inspection, our technician found the 8-inch clay flue lining was heavily spalled from condensate attack, with mortar joints eroded down nearly half an inch. We recommended a HeatShield flue relining to restore safe venting, and the customer approved the work on the spot. Level 2 inspections in Selden range from $350–$550.
Creosote Removal
Creosote accumulation in Selden isn’t just about how often you burn. The oversized gas flues we see throughout the 11784 area create incomplete combustion patterns that deposit soot and acidic residue at abnormal rates — especially on the upper flue walls where draft velocity drops. We remove glazed, powdery, and tar-like creosote deposits using rotary brushes and professional-grade vacuums, not the hardware-store tools that scratch tile or leave debris behind. Heavy creosote removal in Selden typically adds $75–$150 to the base sweep price.
Soot Removal & Fireplace Cleaning
Selden’s original decorative fireplaces — the ones built alongside the heating-appliance flue in those 1960s ranches and split-levels — often sit unused for years, then get fired up for holidays without proper cleaning. We remove soot from firebox walls, smoke chamber, and damper assemblies, checking for proper draft and clearances. The marine-influenced humidity here means soot absorbs moisture and hardens into a corrosive paste if left sitting. A thorough fireplace cleaning in Selden runs $220–$340 depending on accessibility and buildup severity.
Annual Sweep
For Selden homeowners burning wood regularly — or running gas inserts in original fireplaces — we recommend annual sweeping before the heating season. We schedule these aggressively in September and October because once the first nor’easter hits, emergency calls spike and appointment windows compress. Annual sweeps in Selden are $180–$250.

Trusted Brands We Service in Selden
We install DuraFlex, HeatShield, and Olympia Chimney materials — the brands professionals specify, not the retail-grade products pulled off a shelf. For Selden’s coastal climate, this matters. The salt-laden humidity that accelerates mortar erosion on exposed stacks also corrodes lesser-quality stainless steel and premature-failure liner materials. We stock HeatShield cerfractory foam and DuraFlex flexible liner locally, which means relining work doesn’t wait on shipping when your inspection reveals immediate needs. When we recommend a product for your Selden chimney, it’s because that material has survived 14 years of our own callback tracking — not because a distributor offered a volume rebate.
Common Chimney Cleaning & Sweep Problems We See in Selden Homes
- Excess creosote buildup from oversized gas flues. The 8-inch clay flues common in Selden’s 1960s–1970s housing stock were designed for oil heat’s hotter, faster exhaust. After gas conversion, the cooler exhaust lingers, deposits acidic condensate, and creates rapid mortar joint deterioration. Flue gas leakage into the chimney chase follows — a pattern we document on nearly every Level 2 inspection in post-conversion homes.
- Freeze-thaw crown and mortar damage. Central Suffolk County’s repeated winter freeze-thaw cycles, amplified by nor’easter snow saturation, cause chimney crowns to spall and crack. Water enters, freezes, expands, and fractures the crown further. By spring, we’re repairing crowns on Selden homes that seemed fine in October.
- Coastal humidity accelerating exterior deterioration. The marine-influenced humidity from Long Island Sound and the Atlantic accelerates efflorescence — that white mineral staining — and actively erodes mortar joints on exposed chimney stacks. Selden chimneys face this double exposure, and the deterioration shortens exterior lifespan measurably compared to inland Suffolk County.
- Cracked or missing clay tile liner sections after 50+ years. The original clay tile in Selden’s two-flue chimneys has endured more than five decades of thermal cycling. Tiles crack, shift, or fall away entirely, creating gaps that allow heat transfer to surrounding combustibles. We find this on routine sweeps in homes where the homeowner assumed “it’s been fine this long.”

FAQs — Chimney Cleaning & Sweep in Selden
The oversized 8-inch clay flue designed for oil heat runs too cool for gas exhaust, causing acidic condensate and soot accumulation that standard gas flues don’t produce. We see this pattern repeatedly on streets off Boyle Road and Middle Country Road where conversions clustered between 2015–2022. Call (888) 975-6389 to schedule a Level 2 inspection if your conversion was more than two years ago and hasn’t been camera-inspected.
Nor’easter-saturated chimney crowns crack and spall, allowing water infiltration that fractures mortar beds through repeated freezing and expansion. This is the leading repair driver on Selden homes with original 1960s–1970s construction. Annual inspections catch crown deterioration before structural damage spreads.
Yes — we install HeatShield cerfractory foam relining and DuraFlex stainless liners specifically sized to match your gas appliance’s output, correcting the mismatch that causes condensate damage in converted Selden homes. Gary Murphy handles the sizing and installation personally. Call (888) 975-6389 for a free assessment of your flue dimensions.
Schedule a Level 2 inspection within the first heating season after conversion, then every 3–5 years if no changes are made. The condensate damage we document in Selden’s post-conversion homes typically appears within 2–3 years, so early inspection prevents accelerated deterioration from going unnoticed.
We specify DuraFlex, HeatShield, and Olympia Chimney materials — professional-grade products with proven resistance to salt-air corrosion and thermal cycling. These are the brands chimney professionals choose for Long Island’s marine environment, not retail alternatives that fail prematurely under coastal exposure.
