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 Commack, NY | Top Hat Chimney
We provide independent Commack Chimney Cleaning & Sweep and DuraFlex inspection across Commack, NY. What makes our DuraFlex work different here is simple: we know what happens when a liner sized for a 100,000 BTU oil burner gets asked to vent a 60,000 BTU gas furnace, because we see it weekly in Commack’s 1950s and 60s ranches. That mismatch drives most of the corrosion, blockage, and draft complaints we’re called out for. Call (631) 502-3612 for a straight answer and an honest look at your liner.
Top Hat Chimney has been at this since 1999. We’re not a DuraFlex dealer and we don’t pretend to be authorized by the manufacturer. Wendell Pike and his crew work on DuraFlex Pro, DuraFlex 316Ti, DuraFlex 304, and DuraFlex Aluminum liners every season in Commack, fixing what previous owners and rushed oil-to-gas conversion contractors left behind. If you need a cleaning, a cap, or an honest assessment of whether your liner is still doing its job, you’ll get the camera footage and a plain-English verdict, every time, no exceptions. For deeper background on the systems we service, see our DuraFlex sales & service page.
Why Commack Residents Choose Us for DuraFlex Service
Wendell Pike grew up in San Diego, but he’s spent the better part of two decades running crews through Suffolk County, including plenty of jobs in the Burr Farms neighborhood of Commack. He learned the trade at Southwestern College in Chula Vista and picked up his first brush before he was twenty-five. Since 1999, he’s been inside more Commack flues than he can count, and he’ll tell you plainly when a liner doesn’t need replacing yet. If it does not need doing, he will be the first one to tell you.
Commack homeowners choose us for DuraFlex work because we’re the locally owned, owner-operated alternative to the national outfits. The number you hear on the phone is the number on the invoice. A live person answers every call, around the clock, and it may well be Wendell himself picking up. Every job carries the 90-Day Done Right Promise in writing: if it’s not done right, one call brings us back at no additional cost. We also offer $40 off any Chimney Repair in Commack over $200, a free second opinion on any written estimate, no trip charge inside the county, and 10% off always for seniors and veterans.
Common DuraFlex Chimney Cleaning Problems We Solve in Commack
- Pinhole corrosion in DuraFlex Aluminum liners. Commack’s 1960s and 70s chimneys often have offsets built into the original clay tile. When a high-efficiency gas furnace sends cool exhaust through a DuraFlex Aluminum liner, condensate pools in those low spots. We find pinholes there during routine cleanings, and they’re a red flag that the liner is near the end of its service life.
- Crushed or kinked DuraFlex Pro sections. Oil-to-gas conversion contractors in Commack sometimes pulled the liner through the original clay tile offset without a pull cone. The result is a crushed section against the flue wall, uninsulated and pinched. We find these with a Level 2 camera and tell you honestly whether section repair or full replacement makes sense.
- Improperly sealed joints on DuraFlex 316Ti liners. The adapter plate where the liner meets the clay tile crown is a common failure point. Through Commack winters, flue gas and condensate weep back into the masonry chase at that joint. You’ll see staining on the exterior brick, sometimes efflorescence. We replace the seal with the right DuraFlex-compatible materials and document it on camera.
- Animal intrusion through missing or non-brand caps. Squirrels and raccoons get into Commack ranch chimneys through absent or generic caps. They nest above the DuraFlex liner inlet, and the nesting debris blocks draft and creates creosote accumulation. We install proper DuraFlex-compatible caps and clean the debris out before it becomes a chimney fire risk.
- Creosote glaze above the liner inlet. Third-degree creosote is a glaze. It forms when a wood-burning fireplace vents through a liner that was never sized for wood use, or when burning wet wood on Long Island. In Commack, we see this most often in homes that haven’t had a professional cleaning since the original oil furnace was swapped out. First-degree creosote is a brush job; third-degree is a glaze, and it needs mechanical removal.
DuraFlex Service in Commack: What Local Conditions Mean for Your Equipment
Here’s the thing about Commack that shapes nearly every DuraFlex inspection we do here: this town developed almost entirely between 1950 and 1975, and a huge share of those original chimneys were built to vent 100,000-plus BTU oil burners through clay tile liners sized for that load. When National Grid expanded natural gas service into central Suffolk County, thousands of Commack homeowners converted to gas furnaces that put out 60,000 BTUs and left the original oversized chimney in place. The DuraFlex Aluminum liner that often got pulled in during those conversions was a band-aid on a sizing problem. Our inspections in Burr Farms and throughout Commack almost always start with one question: was this liner ever sized for the current appliance? Because the original tile wasn’t.
One job off Harned Road sticks with us. A split-level built in 1972 had been converted to gas in 2004. The DuraFlex Aluminum liner we pulled out was severely corroded, with multiple pinholes where condensate had pooled at a 15-degree offset. The top plate was missing its storm collar entirely. We documented the failure with a Level 2 camera, removed the degraded sections, replaced the top connector and cap with a proper DuraFlex-compatible crown-mount, and advised full relining with 316Ti before next heating season. That’s the kind of thing you don’t know until someone actually looks.
DuraFlex Models & Products We Service in Commack
We work on the full DuraFlex line: DuraFlex Pro, DuraFlex 316Ti, DuraFlex 304, and DuraFlex Aluminum. When a liner is sound but has a failed joint or cap, we recommend OEM DuraFlex replacement sections, connectors, and caps. Mixing metallurgies is how you create galvanic corrosion, and we won’t do it. That said, we’re clear about when patching is the wrong call. If a liner segment is crushed, corroded, or showing multiple pinholes, full replacement beats section patching, especially given Commack’s freeze-thaw cycling. We stock common DuraFlex-compatible connectors, caps, and storm collars for fast turnaround on Commack jobs, so you’re not waiting on a shipment from a warehouse two states away.
DuraFlex Service Pricing in Commack
A DuraFlex chimney cleaning in Commack typically runs between $180 and $340, depending on the liner condition, creosote stage, and whether animal debris needs to be removed. A Level 2 inspection with camera documentation adds $150 to $300. Cap replacement on a DuraFlex liner runs $120 to $400 depending on the cap type and crown condition. If we find a failed joint or leaking adapter plate, that repair adds $75 to $250. A full liner replacement, when it’s genuinely needed, runs $2,800 to $6,500 for most Commack homes. Every estimate is free, and the number we quote before the truck rolls is the number you’ll see on the invoice. Call (631) 502-3612 and we’ll walk you through what your chimney actually needs.

FAQs - DuraFlex Chimney Cleaning in Commack
Rust spots that soon after a gas conversion means condensate is pooling inside the liner, almost always at an offset in the original clay tile. Commack’s 1950s and 60s chimneys were built for oil burners that ran hot and dry. Gas furnaces run cooler and produce acidic condensate. If the liner was undersized or uninsulated, that condensate sits in low spots and eats through aluminum in under a decade. This is often a sign the liner was never right for the appliance. Call (631) 502-3612 and we’ll camera the liner and show you exactly where it’s failing.
Yes. We use poly brushes sized to the liner diameter and rotary tools only when creosote grade requires it, and only with the right head for stainless or aluminum. Scratched liners are usually the result of someone using a steel brush on a 316Ti liner, or forcing a brush through a kinked section. Your flue doesn’t care how the fire looks. It cares how it breathes. We clean it without turning a serviceable liner into a liability.
It usually means the liner was installed without documentation, or the installer used a liner not listed for the appliance it now vents. In Commack, this comes up constantly on oil-to-gas conversions where the original clay tile was never relined, or where a DuraFlex Aluminum liner was pulled in for a gas furnace that required stainless. It doesn’t automatically mean the chimney is dangerous today. It means the liner needs an honest Level 2 assessment to determine whether it’s safe to use. We’ll give you the camera footage and a plain-English verdict, every time, no exceptions. Call (631) 502-3612 to schedule one.
Central Suffolk County’s wet Atlantic winters, with repeated crossings of the freezing point, mainly attack the masonry: mortar joints, crowns, and the clay tile surrounding the liner. The liner itself is metal and doesn’t spall. But when the surrounding masonry shifts and cracks, it can pinch or kink a liner where it passes through an offset. That’s why spring inspections in Commack routinely turn up frost damage that went unnoticed at the end of heating season. A compromised crown also lets water track down the outside of the liner, accelerating rust at the top plate. We check both liner and masonry because they fail as a system.
Absolutely. A missing screen is a cap replacement, not a liner replacement. We’ll match the cap to your DuraFlex liner diameter and crown style, use a DuraFlex-compatible crown-mount, and make sure the storm collar is seated properly, because a missing storm collar is how water gets behind the top plate in the first place. We keep common caps in stock for Commack ranch chimneys specifically because critters in the flue are a year-round problem here. Call (631) 502-3612 and we’ll get the right cap on before the next squirrel moves in.
