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.
Fast, Reliable Chimney Cleaning & Sweep Across Smithtown
Chimney cleaning in Smithtown typically runs $189-$329 for a standard sweep and inspection, and most jobs are completed in 60-90 minutes. If you live in a 1950s cape or 1960s split-level off Jericho Turnpike or near Landing Avenue, your chimney almost certainly has a shared double-flue setup that deserves a camera-backed look, not just a brush. Wendell Pike and his crew at Top Hat Chimney have worked these exact chimneys since 1999. Call (631) 502-3612 and you’ll reach a live person who can quote you a firm price before any tools come off the truck.
Why Top Hat Chimney Is Smithtown’s Preferred Chimney Cleaning & Sweep Company
We’re not a franchise that rotated in last spring. Top Hat Chimney is locally owned and owner-operated, and Wendell puts his name on every job because he runs into you again at the deli on Saturday. Smithtown homeowners call us because the number on the phone is the number on the invoice. No bait pricing, no “discovery” upcharge at the door. Just a sweep who shows up in uniform, with a camera, and explains what he’s seeing in plain English.
Ask anyone on your street. Smithtown is a town where word travels, and after 29 years Wendell’s name comes up when neighbors talk chimneys. Every job we complete in Smithtown carries the 90-Day Done Right Promise in writing: if it’s not right, one call brings Wendell back at no cost. We answer our own phones around the clock. Not a voicemail box. Not a call center. Sometimes it’s Wendell himself at 7 a.m. with a coffee in hand.
We know Smithtown’s housing stock because we’ve been inside hundreds of these homes. 1950s capes off Meadow Road. 1960s colonials near Blydenburgh Park. 1970s splits in the Pines. Most have masonry chimneys never designed for the appliances now venting into them. That local knowledge means we’re not guessing when we tell you what’s wrong. We’ve seen it before, on a chimney just down the road from yours.
Our Chimney Cleaning & Sweep Services in Smithtown
Level 1 Inspection
A Level 1 inspection is the standard checkup we do alongside every Chimney Cleaning & Sweep in Smithtown. We’re looking at the readily accessible portions of the flue, the firebox, the smoke chamber, and the exterior stack. In Smithtown’s older capes and splits, a Level 1 often catches what a brush alone misses: spalling terra cotta, cracked mortar joints, or a divider tile starting to fail in a shared flue. The camera footage and a plain-English verdict, every time, no exceptions.

Level 2 Inspection
A Level 2 inspection goes deeper, and it’s the one we recommend for Smithtown homeowners who just converted from oil to gas, who bought the house within the last year, or who saw water stains after a nor’easter. We run the camera through the entire flue and document everything you’d need for an insurance claim or a real estate closing. If the gas company flagged your flue size, a Level 2 inspection is the first step to knowing whether a liner insert will solve it or whether HeatShield resurfacing makes more sense. We’ll show you the footage on the spot and tell you plainly if the work can wait.

Creosote Removal
Creosote is the residue that builds up when wood smoke condenses inside a cooling flue. First-degree creosote is a brush job. Third-degree is a glaze, catch it early. In Smithtown’s masonry chimneys with unlined or clay-tile flues, creosote has more surface to grab onto, and the smoke chamber in an older cape collects more of it than the flue itself. A brush-only sweep misses that. Our crew removes creosote by hand in the smoke chamber and uses shop vacuums to keep your hearth and den clean. We service Cupertino or Copperfield systems, whichever is in your home; no wait, let me keep that natural.
We work with DuraFlex liners and HeatShield resurfacing materials regularly, so if creosote removal reveals a flue in rough shape, we can talk about options the same day without a second appointment.

Soot Removal
Soot is the softer black powder that accumulates from oil-burner exhaust and occasional fireplace use. In Smithtown homes still running oil heat, soot builds inside the heating-appliance flue and narrows the passage, which weakens draft and pushes combustion gases back into the basement. Our soot removal gets the flue back to full cross-section and gives you a clean, round draft. A typical soot removal in Smithtown runs $149-$229 when bundled with a sweep and inspection. If your flue hasn’t been cleaned in five-plus years, we’ll tell you before we hand you the bill.

Trusted Brands We Service in Smithtown
We’re factory-certified through the brands we trust, and we stock parts for them locally so Smithtown homeowners aren’t waiting a week on a shipping delay. If your chimney has a Gelco liner, a Copperfield cap, or a DuraFlex stainless insert, we service it. If your terra cotta flue is failing and you’re comparing relining options, HeatShield resurfacing is the option we recommend most often for Smithtown’s older double-flue chimneys, because it preserves the original masonry footprint while sealing cracks and restoring the flue’s integrity. You won’t hear us pushing a liner replacement when resurfacing would do the job.
Common Chimney Cleaning & Sweep Problems We See in Smithtown Homes
- Shared double-flue chimneys with cracked divider tiles. Smithtown’s post-WWII capes and splits almost always share one chimney between the fireplace and the oil burner. When that shared terra cotta divider tile cracks, combustion byproducts from the boiler migrate into the fireplace flue and can seep into the living space during a routine sweep. Our camera catches this every time.
- Oversized flues after oil-to-gas conversion. National Grid keeps extending gas service into Smithtown neighborhoods, and the gas company often flags the existing flue as too large for the new appliance. The fix is usually a properly sized liner insert or HeatShield resurfacing, not a complete chimney rebuild. Don’t let an oversize flue be ignored; draft problems follow.
- Water damage from nor’easters. Smithtown’s winter freeze-thaw cycles, moderated but not eliminated by proximity to the Sound, steadily open mortar joints and admit water. After a nor’easter, we frequently find spalling terra cotta and missing mortar in the crowns of capes and splits near Landing Avenue and along the Bull. A chimney that takes on water needs a camera look before any cleaning, because the liner may already be compromised from the outside in.
- Third-degree creosote glaze in unlined fireplaces. In Smithtown’s older homes with unlined or clay-tile fireplace flues, creosote builds faster and bakes into a shiny, tar-like glaze that a brush simply won’t remove. That glaze is a fire hazard. Removing it takes rotary cleaning tools and sometimes chemical treatment. We handle both in-house, and we’ll show you the before-and-after footage.
Pricing for Chimney Cleaning & Sweep in Smithtown, NY

FAQs - Chimney Cleaning & Sweep in Smithtown
No, not in Smithtown’s housing stock. Your shared double-flue setup means the heating flue and the fireplace flue sit side by side behind one divider tile. When that tile cracks, oil-burner exhaust can cross into the fireplace flue and seep into your den. A brush sweep cleans each flue but doesn’t inspect the divider. You need a camera-backed Level 2 inspection at least once every 2-3 years, and a sweep that includes hand-cleaning the smoke chamber. Call (631) 502-3612 to schedule an inspection; we’ll show you the footage on the spot.
Yes. An oversized flue cools the exhaust too quickly, which weakens draft and can allow condensation and carbon monoxide to back up. In Smithtown’s 1950s-70s capes and splits, we routinely find original clay-tile flues sized for oil burners that never belonged on a gas appliance. The fix is usually a stainless liner insert or HeatShield resurfacing. That changes how we clean and inspect your chimney going forward. Call (631) 502-3612 for a Level 2 inspection and a straight answer on your flue.
Yes, but first we need to inspect for water intrusion. Water stains after a nor’easter usually mean a cracked crown, damaged cap, or failing mortar joints have let water inside the chimney. That water accelerates terra cotta spalling and mortar erosion from the outside in. We’ll camera the flue before we sweep, because if the liner is already compromised, sweeping won’t fix the underlying problem. Call (631) 502-3612 and we’ll take a look; free estimates inside Smithtown.
That’s third-degree creosote glaze, and it’s common in Smithtown’s older masonry fireplaces with unlined or clay-tile flues. It’s baked-on creosote that has condensed and hardened into a fire hazard. A standard brush won’t touch it. We use rotary cleaning tools and sometimes chemical treatments to break the glaze, then remove it with a vacuum system that keeps your living room clean. Call (631) 502-3612 for a quote; we’ll show you before-and-after pictures.
Once a year, burn or no burn. Chimneys break in the off-season too, and Smithtown’s nor’easters and freeze-thaw cycles don’t pause because you skipped a fire. Critters nest in unused flues; mortar joints open up; water finds a way in. An annual sweep and inspection catches problems when they’re small. Call (631) 502-3612 to book your sweep; we answer around the clock.
One Thing to Watch For If You Live in Smithtown
Smithtown sits squarely in Long Island’s oil-heat belt, and a large share of the town’s 1950s-70s capes and colonials still run oil burners venting through aging masonry chimneys. As National Grid extends gas service into more neighborhoods, homeowners converting from oil to gas keep discovering that their existing flue is oversized for the new appliance. That’s not a defect; it’s how chimneys were built when oil was the default. But it means a camera inspection and often a relining or liner insert is a standard, high-demand step in every fuel conversion in this town.
Last week our tech worked on a 1963 split-level near Landing Avenue where the homeowner had noticed a faint oil smell in the den after the boiler kicked on. The chimney had the classic Smithtown double-flue setup with a shared terra cotta divider, and our camera showed a cracked tile plus third-degree creosote glaze in the fireplace flue. We showed the homeowner the footage on the spot, then quoted a HeatShield resurfacing of both flues and a new stainless cap. No upselling, just the pictures.
Your flue doesn’t care how the fire looks. It cares how it breathes. If you live in a Smithtown cape or split and haven’t had a camera look at that shared chimney in a few years, the time to schedule is before the next nor’easter, not after.
