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 Chimney Cleaning & Sweep Across Smithtown
Chimney cleaning in Smithtown usually runs between $189 and $329 for a standard sweep, and most homes here need something closer to a full inspection than a quick brush-out. That’s because Smithtown’s housing stock wasn’t built for the way we heat now. The mid-century Cape Cods, ranches, and split-levels that fill Kings Park, Nesconset, and central Smithtown were framed around oil-fired boilers, and their flues carry sulfur-laden soot, not the dry creosote you’d find in a wood-burning town. If you’ve got a fireplace that’s been acting up, or a boiler flue that hasn’t been looked at in twenty years, call Wendell and his crew at (516) 968-5380. We’re local, we answer the phone, and we’ll tell you straight what your chimney needs and what can wait.
Why Top Hat Chimney Is Smithtown’s Preferred Chimney Cleaning & Sweep Company
Top Hat Chimney is Wendell Pike’s company, and it’s been running since 1999. Not a franchise that rotated in last spring. Wendell put his name and license number on the work twenty-nine years ago and hasn’t changed the formula since: answer the phone, show up when you say you will, price the job before a single tool comes off the truck, and stand behind it in writing. Ask anyone on your street. In Smithtown, that matters more than a truck wrap and a jingle.
Our Smithtown customers get the same crew, the same pricing, and the same promise as everyone else: a 90-Day Done Right Promise stamped on every job. If it’s not right, one call brings Wendell back. No arguing, no call center, no voicemail maze. And we don’t do the bait-and-switch the national outfits are famous for. The number you hear on the phone is the number on the invoice.
We’ve worked the same subdivisions long enough to know what we’re walking into before we climb the ladder. A 1968 split-level in Kings Park has a different set of problems than a newer colonial on the south edge of town. Knowing that up front saves you money and saves us from guessing.
Our Chimney Cleaning & Sweep Services in Smithtown
If you’re looking for a full Chimney Cleaning & Sweep team that understands mid-century Long Island construction, you’ve found it. We don’t run a one-size-fits-all sweep. We match the service to the home and the fuel. Here’s what that looks like across Smithtown:
Level 1 Inspection
This is the once-a-year checkup. We run the camera up, confirm the flue is clear and drafting, and give you a plain-English verdict. In Smithtown, a Level 1 is the minimum you want before burning season, especially if you’ve got a wood fireplace that hasn’t been used since spring. Most homes here get this done in under an hour.
Level 2 Inspection
A Level 2 is a deeper camera inspection, and it’s the one Smithtown buyers and sellers ask for most. Real-estate transactions in Suffolk County routinely hinge on a Level 2 finding hidden flue damage. If you’re selling a Kings Park ranch or buying a Nesconset split-level, this is the inspection that tells you whether that original brick chase is safe or needs a stainless liner. We give you the camera footage and a written report, no exceptions.
Creosote Removal
First-degree creosote is a brush job. Third-degree is a glaze. Catch it early. In Smithtown, we run into tar-glazed fireplace flues in homes that were converted from oil to wood without relining. A brush won’t take that off. We’ll show you on camera what you’re dealing with and tell you honestly if it’s a sweep or a reline. Try to charge someone for a brush-out that won’t work in this town, and word spreads.
Soot Removal
Most Smithtown chimneys vent oil, and oil soot is a different animal: acidic, sulfur-heavy, and hard on masonry. Left alone, it eats the mortar from the inside out. We remove it properly, check the flue for damage it’s already caused, and tell you if parging or a liner is needed. This is the service that matters most for the oil-to-gas conversions happening all over the town right now. Your flue doesn’t care how the fire looks. It cares how it breathes.

Trusted Brands We Service in Smithtown
When a Smithtown flue needs relining or repair, we work with brands that hold up to salt air and freeze-thaw: HeatShield, Gelco, and DuraFlex stainless steel. We stock common parts locally, so a liner job in Kings Park doesn’t wait on a warehouse in Ohio. These aren’t budget knockoffs. They’re the products we’d put in our own flues, and we back them with the same 90-Day Done Right Promise.
Common Chimney Cleaning & Sweep Problems We See in Smithtown Homes
- Cross-contamination in shared chases. Many Smithtown homes have an oil-boiler flue and a fireplace flue in the same brick chase with minimal separation. When mortar fails between them, boiler exhaust pushes into the fireplace and sometimes into the living space. We see this constantly in Kings Park and Nesconset subdivisions.
- Salt-air mortar erosion. Smithtown sits minutes from Long Island Sound. Salt-laden air softens lime-based mortar significantly faster than inland Suffolk, and roughly 100 freeze-thaw cycles a year pry it apart. Cracked crowns and rusted dampers are the result.
- Tar glaze from oil-to-wood conversions. Homeowners convert, then light a fire for the first New England winter, and the old oil residue bakes into a hard glaze. A brush won’t touch it. The fireplace flue needs a proper reline before it’s safe for wood.
- Hidden unlined chases. In Smithtown’s mid-century building boom, some builders ran flues through brick chases with no tile liner at all. These went uninspected for decades. A Level 2 camera inspection is the only way to catch them before they fail a real-estate transaction or worse.
Pricing for Chimney Cleaning & Sweep in Smithtown, NY
A standard chimney sweep in Smithtown runs $189 to $329 for one flue. Two flues (boiler plus fireplace) runs $269 to $449. A Level 2 camera inspection adds $149 to $249 depending on access and height. If you’re converting from oil to gas, a stainless reline in this area runs $2,800 to $5,400, and a dual-flue retrofit in a shared Kings Park chase can reach $6,500. That’s the honest range. We give you a firm number before the ladder comes off the truck, and estimates are free. We also stock HeatShield and Gelco products for smaller repairs, and a patch-and-parse job is usually far less than a full reline. The camera footage decides. You see it, we walk you through it, then you choose. Call (516) 968-5380 for an exact quote. $40 off any repair over $200, and 10% off always for seniors and veterans.

FAQs - Chimney Cleaning & Sweep in Smithtown
Oil flues carry acidic, sulfur-heavy soot that corrodes the inside of a brick chimney. Gas exhaust is cooler and carries moisture. When you convert from oil to gas, that moisture mixes with the old oil residue and creates a corrosive slurry that eats the mortar and can leak into the house. A stainless steel liner separates the flue gases from the masonry. In Smithtown, where oil-to-gas conversion is happening block by block, we recommend a Level 2 camera inspection before you fire up a new gas boiler in an old flue. Call (516) 968-5380 and we’ll show you what’s actually inside your chase.
It changes everything. A shared chase means the oil-boiler flue and the fireplace flue run side by side in the same masonry pocket. If the separation between them has failed, sweeping one flue can push debris into the other one. And when the boiler kicks on during a fire, a backdraft can push smoke and carbon monoxide right through the fireplace damper into the living room. We inspect the shared chase with a camera before any sweep. If separation is compromised, the fix is a dual-channel DuraFlex stainless liner system, not just a brush-out.
That white powder is efflorescence. It’s salt and mineral deposits wicking through the brick as moisture evaporates. In Smithtown, the salt-laden air off Long Island Sound accelerates this process, and combined with 100 freeze-thaw cycles a year, it’s a signal that your mortar joints are failing and water is getting in. A sealed crown and tuckpointed mortar joints are typically the fix. It’s rarely a DIY job; the underlying water entry has to be addressed or the powdery film comes right back.
No. A wire brush cannot remove third-degree creosote glaze. That glaze is a hard, shiny, tar-like deposit that forms when oil residue or wet wood burns at low temperature. It’s a fire hazard and it requires mechanical removal with a rotary chain system or a full stainless reline if the flue is too far gone. In Smithtown, this usually shows up in homes converted from oil to wood. We’ll show you the glaze on our camera before we quote anything. If a brush job won’t solve it, we’ll say so and save you the money.
Because the problem isn’t a dirty flue. It’s the shared chase design itself. Many Nesconset split-levels were built with a boiler flue and fireplace flue sharing the same brick chase without proper separation. When both are in use, they compete for the same air. When the boiler runs, it pulls air down the fireplace flue, and smoke backs up into the house. The permanent fix is a properly separated stainless liner system. We’ve done this fix in subdivisions all over Nesconset and Kings Park, and it transforms how the fireplace drafts. Call (516) 968-5380 and we’ll come see whether you’ve got a shared chase problem.
