We know Smithtown’s chimneys. Not the generic kind you read about on national sites—the actual brick-and-mortar flues venting through Cape Cods along Meadow Road, raised ranches off Jericho Turnpike, and split-levels in the 11787 ZIP code. Fourteen years in one trade means we’ve cleaned, inspected, and repaired hundreds of chimneys in this town. We understand the local building stock, the oil-heating legacy, and how Smithtown’s North Shore exposure to nor’easter-driven freeze-thaw cycles punishes masonry that hasn’t been properly maintained. When you hire our Chimney Cleaning & Sweep service, Gary Murphy shows up himself. Not a subcontractor. Not a rotating crew. The owner, with his hands on the brushes and his eyes inside your flue.
Why Sterling Chimney Cleaning Bridgeport Is Smithtown’s Preferred Chimney Cleaning & Sweep Company
More than 1,200 homeowners have trusted us, and our 1,234 verified reviews averaging 4.7 stars reflect that volume of real-world experience. Smithtown customers specifically mention Gary’s willingness to explain what he found—oil-flue conversions, hidden tile dimensions, mortar deterioration from Long Island Sound moisture—and show them the camera footage.
We’re typically on-site in Smithtown within 24–48 hours for standard sweeps, same-day for emergencies involving blocked flues or suspected CO backdrafting. That matters in a town where winter storms can knock out power and push homeowners to fireplaces they haven’t used since last season.
Our local knowledge runs deep. We know that Smithtown’s post-WWII housing boom produced masonry chimneys designed for oil-fired boilers, not wood-burning fireplaces. We know the Town of Smithtown’s building department flags certain flue configurations during real-estate transfers. And we know that a 6-inch oil-flue tile hidden behind a decorative hearth opening isn’t just a quirk—it’s a code violation that can derail a sale or create a fire hazard. That kind of specificity doesn’t come from a franchise manual.
Our Chimney Cleaning & Sweep Services in Smithtown
Level 1 Inspection
A Level 1 inspection is the annual standard for chimneys in regular use—accessible portions of the appliance, flue, and chimney structure examined without specialized tools. In Smithtown, we perform more Level 1 inspections on oil-to-gas conversion chimneys than on traditional wood-burning systems. Gary checks for proper venting path, clearances to combustibles, and signs of moisture intrusion from those damp maritime winters. If your Cape Cod on Old Northport Road hasn’t been inspected since you bought it, this is where we start.
Level 2 Inspection
Level 2 inspections are required when a property changes hands, after a chimney fire or weather event, or when you’re modifying your appliance or fuel type. This is our most-requested service in Smithtown, and for good reason. We run a video camera the full length of the flue, examining every tile joint, mortar bed, and liner connection. In Smithtown’s 1955–1985 housing stock, we regularly find 6-inch round oil-flue tiles inside chimneys that now have decorative fireplace openings—a dangerous mismatch that Town of Smithtown inspectors flag during real-estate transactions. Our Level 2 includes a written report with video stills, documenting exactly what a buyer’s inspector will see.
Creosote Removal
Wood-burning creosote is flammable, tar-like, and familiar. But Smithtown’s oil-heating legacy means many flues contain something different: acidic, sulfurous deposits from decades of oil combustion. Standard wood-creosote brushes and chemicals won’t touch it. We use specialized chemical rinses formulated for oil-combustion residue, then mechanical brushing with properly sized poly or wire brushes. Attempting to clean an oil-flue chimney with standard wood-creosote methods leaves corrosive deposits that continue eating tile and mortar. We’ve rebuilt too many chimneys where that shortcut was taken.
Soot Removal
Soot accumulation reduces draft efficiency and can harbor moisture against flue walls. In Smithtown’s damp climate, that moisture accelerates deterioration. Our soot removal process uses HEPA-contained vacuum systems and graduated brushing to remove buildup without introducing new debris into your home. For homeowners near the Nissequogue River watershed, where humidity runs higher than inland Suffolk County, we pay particular attention to organic debris—leaves, nesting material, moisture-retaining buildup—that can block proper venting.
Annual Sweep
The National Fire Protection Association recommends annual inspection; sweeping frequency depends on use and fuel type. For Smithtown homeowners who’ve converted to gas inserts, annual sweeping may seem unnecessary—but we still find blocked caps, deteriorating crowns, and moisture damage that gas exhaust exacerbates. For those burning wood in converted oil flues, annual sweeping is non-negotiable. We schedule recurring annual sweeps for Smithtown customers, with reminder calls before the heating season.
Fireplace Cleaning
Fireplace cleaning addresses the firebox, smoke shelf, and visible flue throat—areas where ash, soot, and partially burned material accumulate. In Smithtown’s older colonials with multi-flue chimneys, we often find deteriorating mortar joints and no stainless liner, requiring careful cleaning that doesn’t accelerate damage. Our fireplace cleaning includes inspection of the damper assembly, firebrick condition, and hearth sealing.

Trusted Brands We Service in Smithtown
We install DuraFlex stainless liners, HeatShield ceramic resurfacing systems, and Copperfield chimney caps—the materials professionals specify, not the retail-grade products you’ll find at big-box stores. For that Cape Cod on Meadow Road where we relined the oil-flue conversion, we used HeatShield to bring that 6-inch tile up to proper wood-burning dimensions. We stock common sizes and configurations for Smithtown’s dominant housing stock, which means faster turnaround when your inspection reveals a problem and you need it resolved before closing. Famco and Gelco components are on our trucks for same-day cap and damper replacements when conditions allow.
Common Chimney Cleaning & Sweep Problems We See in Smithtown Homes
- Orphaned oil flues after gas conversion. Homeowners switch to natural gas or heat pumps, cap the oil vent, and assume the job is done. The flue is still open at the chimney top, collecting rain, debris, and nesting animals. We find these regularly in Smithtown’s split-levels and raised ranches—chimneys that look fine from the ground but are deteriorating inside from moisture intrusion.
- Decorative hearths added to oil-flue chimneys without relining. A previous owner wanted the ambiance of a fireplace, so they knocked in an opening and connected it to the existing boiler flue. The 6-inch tile can’t handle wood combustion temperatures or volume. We recently swept a Cape Cod on Meadow Road in Smithtown where exactly this scenario existed. Our crew used a HeatShield ceramic liner to reline that flue to proper wood-burning dimensions, then capped the old oil vent—eliminating the fire hazard and getting the homeowner a clean inspection for their sale.
- Freeze-thaw spalling on mortar joints. Smithtown’s position on Long Island’s North Shore exposes chimneys to repeated freeze-thaw cycles driven by nor’easters off Long Island Sound. Moisture penetrates brick and mortar, freezes, expands, and flakes off the face. One unsealed season can destroy a crown or open mortar joints. We catch this during camera inspection before it requires rebuild-level intervention.
- Failed smoke tests on visually intact chimneys. Your chimney looks fine from the driveway. But smoke testing reveals leakage at hidden cracks, deteriorated tile joints, or gaps where the flue meets the smoke chamber. In Smithtown’s oil-flue legacy housing, we often trace these failures to improper conversions or missing liners that a casual inspection misses.

FAQs — Chimney Cleaning & Sweep in Smithtown
You can use it safely only after confirming the flue is properly sized and lined for wood combustion—most 1960s Smithtown chimneys have 6-inch oil-flue tiles that are too narrow and not rated for wood-fire temperatures. We run a Level 2 video inspection to measure interior dimensions and check for cracks or missing liner sections. If the flue is unlined or undersized, we can install a DuraFlex stainless liner or apply HeatShield ceramic resurfacing to bring it to code. Call (888) 975-6389 for a free estimate—Gary will inspect and explain exactly what your chimney needs.
Town of Smithtown inspectors verify that chimney flues match their listed use, are properly lined, and vent safely without leakage or obstruction. The most common failure we see is a decorative fireplace opening connected to an unlined or undersized oil-flue tile—a code violation that stalls closing. Our Level 2 inspection produces documentation that anticipates what the town inspector will flag, so you can address issues before they derail your sale. We provide written reports with video stills accepted by local attorneys and title companies. Call (888) 975-6389 to schedule before you list.
Even infrequently used chimneys in Smithtown need annual inspection and sweeping every 1–2 years, because maritime moisture and organic debris accumulate regardless of burn frequency. Damp, salt-laden air from Long Island Sound accelerates mortar deterioration and rust on metal components. Before that January storm knocks out your power and you light your first fire in eleven months, have us inspect and sweep. Call (888) 975-6389 to schedule in early fall—our calendar fills once the weather turns.
We don’t recommend it. Capping requires confirming the flue is fully abandoned, properly sealed at the appliance connection to prevent CO leakage into living spaces, and vented correctly for any remaining appliances. We’ve found DIY caps that trapped moisture and destroyed flue tiles within two seasons, and others that sealed active vent paths for water heaters or furnaces. Gary handles capping personally, with verification of all connected appliances and proper material selection for Smithtown’s freeze-thaw exposure. Call (888) 975-6389—estimates are free, and the cost of doing it wrong is a full rebuild.
Hidden tile cracks, deteriorated mortar joints, gaps between flue sections, or missing liner segments can all leak combustion gases while the exterior brick appears sound. In Smithtown’s oil-flue legacy housing, we frequently trace smoke-test failures to improper conversions where a hearth opening was added without relining, or to stainless liners that separated at a joint. Our video scan locates the exact breach. Don’t assume cosmetic integrity means functional safety—call (888) 975-6389 for a Level 2 inspection with Gary Murphy.
