Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterDuraFlex Chimney Cleaning in Smithtown, NY | Top Hat Chimney
We provide independent Smithtown Chimney Cleaning & Sweep for DuraFlex liners, and the short answer is this: most DuraFlex liners in this town are attached to oil-burner flues inside 1950s and 60s masonry chimneys, which means the cleaning work here is rarely just about creosote. It is about making sure the liner is still intact while the oil-to-gas conversions keep happening all over Smithtown. Wendell Pike and our crew have worked those double-flue cape cods and split-levels since 1999. Call us at (631) 502-3612 for a straight answer and a free estimate.
Why Smithtown Residents Choose Us for DuraFlex Service
We are an independent shop. We are not manufacturer-affiliated, we are not authorized by DuraFlex, and we do not pretend otherwise. What we are is familiar with how DuraFlex liners actually behave inside Smithtown’s housing stock, because we have been pulling brush heads and camera lines through them for over 29 years. Wendell Pike grew up in San Diego, but he has spent the better part of two decades running crews through Suffolk County, and he learned the trade at Southwestern College in Chula Vista before he picked up his first brush. If a liner does not need cleaning yet, he will say so, and he will save you the appointment. That is the kind of honesty that keeps people in Smithtown calling us back.
We stock OEM-compatible DuraFlex components for the common Chimney Repair in Smithtown we see here, which gets your system back in service faster when a section does fail. Every job comes with our 90-Day Done Right Promise in writing. If it is not right, one call brings the crew back at no additional cost. When we say we stand behind a liner cleaning or a seam repair in Smithtown, that promise is stamped on the job, not just implied.
Common DuraFlex Chimney Cleaning Problems We Solve in Smithtown
- Perforation and pinhole leaks along corrugation valleys. Smithtown’s 1950s oil-burner flues run DuraFlex 316L liners, and when a homeowner converts to gas without relining, the lower exhaust temperatures create acidic condensate that pools at offset joints. That condensate eats pinholes through the liner wall, and by the time we arrive for a cleaning the liner is already compromised.
- Tearing at pop-rivet seams on flexible sections. In split-level chimneys built during the 1960s in Smithtown, original installers pulled flexible DuraFlex around sharp 90-degree offsets in tight framing. The stress point is usually a pop-rivet seam, and years of heating cycles eventually tear it open. We find this during cleanings more often than homeowners expect.
- Vertical seam overlap separation from thermal cycling. Smithtown homes that alternate between an oil burner and a low-mass gas furnace subject the liner to repeated expansion and contraction. On a DuraFlex liner, that cycling can separate the vertical seam overlap, allowing soot and carbon monoxide to leak between the liner wall and the surrounding masonry.
- Corrosion where stainless meets unlined middle sections. Smithtown’s double-flue chimneys often have a fully lined upper section, but a partially unlined middle. Where the DuraFlex stainless connects to that bare masonry, galvanic pitting develops, and the problem is accelerated by chimney crown leaks from nor’easter snow loads. The damage is usually visible on camera before it becomes a safety issue.
- Damper jamming from creosote-glazed liner caps. Wood fireplace flue gases condense on the DuraFlex liner cap in cold weather, and in Smithtown’s freeze-thaw winters that condensate hardens into a glaze that can freeze the damper shut. A cleaning fixes it, but it usually takes a proper brushing and sometimes a cap replacement, not just a quick vacuum.
DuraFlex Service in Smithtown: What Local Conditions Mean for Your Equipment
Smithtown sits squarely in Long Island’s oil-heat belt, where a large share of the town’s 1950s to 70s cape cods and colonials still run oil burners venting through aging single- or double-flue masonry chimneys. National Grid has been extending gas service into Smithtown neighborhoods for years, and as homeowners convert from oil to gas, the existing flues are routinely found to be oversized for the new appliance’s lower exhaust temperatures. When that conversion is not paired with a properly sized liner or an insulated reline, the DuraFlex liner already in the chimney starts condensing acidic flue gas along its full length. Our techs have seen it after DIY conversions that were permitted without any chimney inspection. In the Burr Farms neighborhood of Commack and matching cape cod clusters across Smithtown, the fix is usually a liner resizing or insulation, not just a sweep. That local pattern is the single biggest reason a routine DuraFlex cleaning in Smithtown often turns into a liner assessment.
DuraFlex Models & Products We Service in Smithtown
We work on the DuraFlex sales & service lines most common in Smithtown: the DuraFlex 316L flexible chimney liner, the DuraFlex 304 flexible liner, the DuraFlex UltraPro masonry relining system, and DuraFlex rigid liner sections. Our approach is simple: we use OEM DuraFlex liner sections and termination caps when the damaged run is short and the rest of the liner is serviceable. When a whole-flue replacement makes more sense in a 60-year-old Smithtown chimney, we often switch to a high-grade aftermarket 316L liner that is selected for durability, not for a brand sticker. We keep common repair components on the truck, which means a Smithtown job can usually be finished the same day rather than waiting on a parts shipment.
DuraFlex Service Pricing in Smithtown
A standard DuraFlex chimney cleaning in Smithtown runs $180 to $340. A Level 2 camera inspection, which we recommend before any liner repair or replacement call, is $150 to $350. Liner repairs start around $500 for simple seam fixes, while a full reline of a double-flue Smithtown chimney runs $3,500 to $7,000, and custom jobs or difficult access push toward $10,000. The price is driven by what the camera shows, not by what a sales script says. We give a no-hassle upfront quote before any tool comes off the truck, and the number on the phone is the number on the invoice. We also offer $40 off any repair over $200, a free second opinion on any competing written estimate, no trip charge inside the county, and 10% off always for seniors and veterans. Soft nudge: call (631) 502-3612 for an exact quote, estimates are free.

FAQs - DuraFlex Chimney Cleaning in Smithtown
Yes, and the difference matters. DuraFlex liners in Smithtown are typically paired with oil-burner flues, and that flue needs a yearly sweep regardless of how often you use the fireplace, because combustion byproducts from the heating appliance deposit on the liner wall all winter. Once a year, burn or no burn. Chimneys break in the off-season too, and Smithtown’s freeze-thaw cycles hide liner damage well. Call (631) 502-3612 for a schedule that fits your house and your burn habits, and the estimate is free.
Isolated pinholes or a popped seam can be patched, and we do that when the surrounding liner is solid. Stainless rivets and a high-temp sealant fix a seam; a short run of pinholes can be sleeved. But if the perforation is widespread, or the surrounding masonry is spalled, or the divider tile between the fireplace flue and the oil-burner flue is cracked, a patch is a temporary fix at best. In that case, we recommend complete relining rather than patching, and we will show you the camera footage before you decide. Call us if you have seen soot marks or a draft smell. Estimates are free at (631) 502-3612.
A nor’easter’s wet snow and coastal wind hammer the chimney crown and cap first, and once the crown leaks, water reaches the liner from the outside in. In a DuraFlex liner, that moisture accelerates corrosion at stainless-to-masonry joints and worsens galvanic pitting at unlined middle sections. What starts as a crown leak in a Smithtown winter becomes liner corrosion by spring. The fix is usually crown repair plus liner inspection, and if we find the corrosion early enough, the liner itself survives. Call (631) 502-3612 and we will put eyes on it, camera included, no charge for the trip inside the county.
Yes, with one caveat specific to Smithtown’s double-flue chimneys. The two flues are separated by a shared terra cotta divider tile, and when that tile cracks, flue gases cross between the fireplace and the heating appliance. A DuraFlex liner in one flue does not fix a cracked divider in the other. If both flues are to be lined, each flue needs its own correctly sized DuraFlex liner, and the divider tile must be intact or repaired first. If you own a Smithtown cape cod or split-level from the 1950s or 60s, ask us to check that divider during the camera inspection. The call is free to make: (631) 502-3612.
Most DuraFlex liners we encounter in Smithtown were installed in the 1990s or early 2000s, so they are 20 to 30 years old, often inside chimneys that are 60-plus. Age alone does not warrant replacement. A 316L liner with no perforation, intact seams, and proper sizing is still serviceable at that age. What matters is the camera evidence: pinholes, seam separation, corrosion at joints, or damage to the surrounding masonry. If the liner is sound, we say so and we save you the money. If it is not, the footage tells you why. Get a straight answer from Wendell and his crew at (631) 502-3612. Free estimate, free second opinion on any written competing quote.
