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.

AfterFast, Reliable Fireplace Services Across Nesconset
Most fireplace work in Nesconset comes down to one thing: chimneys that were built for oil heat, not wood fires. Gas fireplace service, wood burning fireplace repair, insert work, and damper fixes on these mid-century homes all need a sweep who understands what these flues were originally designed to do. Top Hat Chimney has been working on Long Island chimneys since 1999, and the patterns we see in Nesconset are distinct. The old terracotta liners, the two-flue layouts, the freeze-thaw damage on soft 1950s brick. We know what we’re looking at before we even ring the doorbell. Call (934) 935-3847 for a free estimate.

Why Top Hat Chimney Is Nesconset’s Preferred Fireplace Services Company
Wendell Pike started Top Hat Chimney in 1999, and he built the business the way a sweep should: his name on the work, his license number published, and a 90-Day Done Right Promise backed up in writing. If something’s not right after we leave, one call brings Wendell and his crew back at no cost to you.
That matters in a place like Nesconset, where the housing stock has a very specific problem. Most of the ranches, Cape Cods, split-levels, and colonials along Smithtown Boulevard and the side streets off Lake Avenue were built between 1950 and 1975. They came with masonry chimneys fitted for oil-fired boilers. When homeowners switch to gas or add a wood burning insert, that old oil flue gets asked to do a job it was never designed for. We see it constantly. Ask anyone on your street.
Phones are answered by a live person around the clock. Not a voicemail box, not a call center. Often Wendell himself. He’ll tell you what he thinks before a single tool comes off the truck.
Our Fireplace Services Services in Nesconset
Wood Burning Fireplace Service
Wood burning fireplaces in Nesconset are almost always an addition to a chimney that started life as an oil exhaust system. We sweep the flue, inspect the liner with a camera, and tell you straight whether that fireplace can burn safely as-is. First-degree creosote is a brush job. Third-degree is a glaze. Catch it early and you’re looking at a standard sweep. Let it go, and you may be looking at a liner.
Fireplace Insert Installation and Service
Homeowners across Nesconset add wood-burning inserts to mid-century chimneys that were never relined for wood temperatures. Town of Smithtown code requires relining before any new appliance is connected to an old flue. Our Fireplace Services team scopes the full run, gives you the camera footage and a plain-English verdict, and installs DuraFlex or HeatShield liners sized for the insert you actually have. No guesswork. No padding.
Damper Repair
Dampers on Nesconset chimneys see more rust than you’d expect. The reason is simple: an oil-burning system exhausted moisture-laden air for decades, and once that flue went dormant or was repurposed for gas, the cast iron dampers sat in humidity. We repair or replace dampers, and we check the whole assembly when we do. Half the time a “draft problem” is actually a damper that doesn’t seat anymore.
Fireplace Conversion
Converting from wood to gas, or from an old gas log set to a sealed direct-vent unit, is a real specialty here. Nesconset homes built for oil heat have flues with the wrong draft characteristics for modern gas appliances. Conversion means either relining or capping the old flue and running a new vent system. We handle the whole job, and we’ll tell you plainly if a conversion isn’t worth doing on your particular chimney.
Trusted Brands We Service in Nesconset
We install and service Famco, Copperfield, DuraFlex, and HeatShield products. We stock common replacement parts and liners locally, so a fireplace insert or damper job in Nesconset doesn’t get hung up waiting on a warehouse three states away. If you’ve got a Famco chimney cap that’s rusting out or a Copperfield damper that won’t hold position, we can usually fix it same trip.
Common Fireplace Services Problems We See in Nesconset Homes
- Dormant oil flues left uncapped after gas conversion. The oil boiler flue sits unused for one or more winters. Animals get in. Tiles crack from moisture. Then someone hooks a new appliance to it without relining, and now you have a code violation and a fire risk inside your chimney chase.
- Freeze-thaw spalling on 1950s brick. Long Island winters oscillate around freezing for weeks at a time, and that repeated expansion and contraction eats at the soft brick and original lime mortar above the roofline. The crown and flashing go first. Once water gets into the chase, you’ll see interior plaster damage near the chimney that gets mistaken for a roof leak.
- Wood-burning inserts on oil flues. The original terracotta liner was sized for low-temperature oil exhaust. Wood fires burn hotter and produce a different draft requirement. Without relining, the old clay tile cracks sooner than you’d believe. Then creosote finds those cracks and now you have a chimney fire waiting for a spark.
- Two-flue confusion. Nesconset split-levels and colonials often have two flues in one chimney: one for the oil boiler, one for a living-room fireplace. People assume both are fine because one works. They’re not. The dormant flue deteriorates faster because nothing ever flows through it to dry it out.

FAQs - Fireplace Services in Nesconset
How do Nesconset’s oil-to-gas conversions affect my fireplace flue?
Your original terracotta flue was sized for low-temperature oil exhaust, and when you convert to gas or add a wood burner, that same flue is being asked to handle temperatures and draft conditions it was never built for. Town of Smithtown code requires relining before any new appliance is connected, but plenty of homeowners never hear that until an inspection flags it. Call (934) 935-3847 and we’ll scope the flue and show you exactly what you’ve got.
Why does my Nesconset chimney need repointing more often than my cousin’s chimney in Westchester?
Nesconset winters hover around the freezing mark for long stretches, and that constant thaw-and-refreeze cycle is what destroys mortar joints and spalls brick. It’s not the cold itself. It’s the oscillation. Westchester has the same winter temperatures, but the brick and mortar there are often harder and newer than the soft 1950s lime-mortar chimneys that make up most of Nesconset’s housing stock. Different masonry, different failure rate.
Can I just stop using my fireplace and skip the yearly inspection?
You can skip it, but the chimney doesn’t stop breaking. Once a year, burn or no burn. Chimneys break in the off-season too. An unused flue in a Nesconset home still collects moisture, still goes through freeze-thaw cycles, and still hosts animals if it’s uncapped. We’ve scoped dormant flues that looked fine from the outside and were crumbling from the inside. The inspection is cheaper than what you’re gambling on. Call (934) 935-3847.
Third-degree creosote-how fast does that happen with a wood stove in Nesconset?
In a wood stove burning less-than-dry wood, third-degree glazed creosote can build within a single season. Long Island humidity works against you here. Firewood stored outside without good airflow picks up moisture, and wet wood makes creosote. A stove that ran all winter can absolutely glaze by March. If you’re burning pine or anything else that smolders, the interval shortens. We’ll tell you whether you have a brush job or a problem after one look.
My split-level has a two-flue chimney-do both flues need servicing?
Yes. Both flues are inside the same masonry structure, and both deteriorate. The dormant flue is often in worse shape because nothing ever flows through it to dry it out. We scope both, every time, no exceptions. The camera footage tells you what’s actually there. If one flue is abandoned, we can cap it properly and line the working flue for whatever appliance is actually using it.
