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.

Why Top Hat Chimney Is Islandia’s Preferred Chimney Cleaning & Sweep Company
We’ve worked enough homes in Islandia to know what’s behind the damper before we open it. The majority of houses here went up during Long Island’s post-war building boom, which means single masonry chimneys that served oil burners first and fireplaces second. That’s not a guess. It’s what we find when we run a camera up the flue on Canterbury Woods, on Serpentine Lane, and along Old Nichols Road.
Wendell Pike founded Top Hat Chimney in 1999, and he still runs the company the way he ran it on day one. His name is on the work. His license number is published for anyone who asks. When a homeowner in Islandia calls, a live person answers, and that person may well be Wendell himself. No call center. No voicemail maze. Our Chimney Cleaning & Sweep team arrives in uniform, background-checked, and gives you an upfront price before a single tool comes off the truck.
Every job we complete in Islandia carries the 90-Day Done Right Promise in writing. If the sweep isn’t right, one call brings us back. No invoice. No argument. That’s the whole promise.
Our Chimney Cleaning & Sweep Services in Islandia
Level 1 Inspection
A Level 1 inspection is what happens during a routine chimney sweep in Islandia, and it covers the readily accessible areas of the flue, the firebox, and the exterior chimney structure. For homes that burn regularly and haven’t changed their heating system, this is usually the right level. We check for creosote buildup, blockages, and obvious masonry problems, then we give you the camera footage and a plain-English verdict. Every time, no exceptions.

Level 2 Inspection
Islandia homeowners who’ve converted from oil to gas heat need a Level 2 inspection, and here’s why. The conversion changes what’s going on inside your original clay-tile flue, and you can’t see that from the ground. We run a camera from the top of the chimney down through the entire liner, documenting cracks, gaps, and any residual oil soot that the HVAC crew didn’t address. If you’ve bought a home in Islandia in the last few years and you don’t know what the flue looked like before the gas furnace went in, a Level 2 is the honest place to start.

Creosote Removal
Islandia’s older capes, ranches, and split-levels often have fireplaces sized generously for the house. They were built to provide real heat. When you burn regularly in those fireplaces, creosote accumulates in stages. First-degree creosote is a brush job. Second-degree is harder but still removable with rotary tools. Third-degree is a glaze, and a standard brush won’t touch it. We see all three stages in Islandia, and we’ll tell you straight which one you have.

Soot Removal
Soot removal matters most in Islandia for the flues that were once tied to oil burners. After a conversion to gas, that old oil flue often sits abandoned, but the soot doesn’t leave on its own. It stays, lining the tile, waiting to mix with moisture from the new gas appliance. We remove it, show you the before-and-after on camera, and then talk about whether the liner needs resurfacing with HeatShield or a full DuraFlex stainless upgrade.

Trusted Brands We Service in Islandia
When an Islandia chimney needs parts, we don’t wait on a shipment from somewhere else. We stock and work with brands built for Long Island conditions, including Famco caps and dampers, Copperfield chimney products, and DuraFlex stainless liners. For older masonry chimneys that aren’t structurally shot but need liner repair, we use HeatShield resurfacing. The parts go in fast because we keep them on the truck. When we recommend a liner replacement or cap replacement, you’ll know the brand, the price, and the reason before we start.
Common Chimney Cleaning & Sweep Problems We See in Islandia Homes
- Abandoned oil flues still carrying soot and creosote. Many Islandia homes converted from oil to gas years ago, and the old burner flue was simply left in place, soot and all. That residue remains a fire risk and must be cleaned before any liner work can be done safely.
- Dual-flue chimneys with cracked tile liners. Homes built in the 1960s and 1970s often have two separate flues, one for the oil burner, one for the fireplace. After five decades of freeze-thaw cycles, hairline cracks in those clay tiles are common, and we catch them with a camera before they become structural failures.
- Third-degree creosote glaze in wood stove flues. Islandia is far enough east that plenty of homes rely on wood stoves for real heat, not just ambiance. Burn two winters without a sweep and that creosote can glaze inside the flue. A standard brush won’t remove it.
- Salt-driven mortar erosion on the chimney crown and upper courses. Salt air from the Great South Bay reaches central Suffolk County and works into mortar joints, especially after nor’easters drive moisture in during late fall. The freeze-thaw cycles then push the damage deeper between cleanings.
Pricing for Chimney Cleaning & Sweep in Islandia, NY
A standard chimney sweep in Islandia runs $189-$279 for a single flue, depending on the condition of the chimney and how much creosote has built up. Level 2 camera inspections add $150-$250. If you have a dual-flue chimney, which is common in Islandia, expect the price to land at the higher end because both flues need to be cleaned and inspected. Soot removal from an abandoned oil flue adds $75-$150, and creosote removal with rotary tools, when it’s second-degree or worse, runs $100-$200 depending on severity. Every estimate is free and upfront. The number you hear on the phone is the number on the invoice, and senior and veteran discounts knock 10% off every time.

FAQs - Chimney Cleaning & Sweep in Islandia
Because the old oil flue didn’t clean itself when the furnace was swapped out. The original clay-tile flue, sized for an oil burner, still carries residual soot and creosote from decades of oil heat. When you add the moisture from a new gas appliance, that old residue becomes a sticky, acidic mess that accelerates liner deterioration. A sweep addresses the residue before you spend anything on liner work. Call (934) 935-3847 and we’ll tell you what’s actually in that flue.
Once a year, burn or no burn. If you heat primarily with wood through a Long Island winter, sweep twice a year, once before burning season and once mid-winter. Wood stoves create heavier creosote loading than open fireplaces, and two winters of neglect can produce third-degree glaze that requires rotary tools and serious labor. The good news is that a mid-winter sweep catches the problem while it’s still a brush job. Call (934) 935-3847 and we’ll get you on the schedule.
Yes. Salt-laden moisture reaches inland Suffolk County and settles on masonry surfaces, working into mortar joints and accelerating brick spalling. Once moisture gets behind the brick face, freeze-thaw cycles push the damage deeper. The crown and upper courses are hit hardest. A routine sweep won’t fix masonry erosion, but a Level 2 inspection will document it before it becomes a structural repair. Call (934) 935-3847 for a camera inspection and a straight answer.
Residual oil soot in an old flue creates two problems. First, it’s a fuel source. If enough creosote and soot remain, exposure to high temperature or a stray ember can ignite it. Second, the new gas appliance produces moisture and acidic condensation that soaks into the soot and attacks the mortar joints between clay tiles. You end up with a deteriorated liner and a documented fire hazard. We address both in a single visit, showing you the camera footage before and after. Call (934) 935-3847 to set it up.
No. Third-degree creosote is a hardened, shiny glaze that a standard wire brush won’t remove. It requires rotary chains or chemical treatments over multiple visits in severe cases. The earlier you catch creosote, the cheaper and faster the job. If you suspect heavy buildup, or if it’s been more than one season since your last sweep, get it checked before burning season. Call (934) 935-3847 and we’ll inspect, quote upfront, and give you a photograph of exactly what’s coating your flue.
