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 Commack
Chimney cleaning in Commack typically costs $189-$325 for a standard sweep and inspection, and most jobs are completed in under two hours. Wendell Pike and his crew at Top Hat Chimney have worked these 1950s-70s ranch, cape, and split-level homes long enough to know what’s behind the damper before they open it. If you’re on Jericho Turnpike, off Harned Road, or tucked into the neighborhoods below the Northern State, call (631) 502-3612 and a live person answers, day or night.
We’re not a national chain that rotates a new tech through every season. Wendell founded Top Hat Chimney in 1999, puts his name and license number on every job, and drives the same roads you do on Saturday morning. The Commack homes we service were built in a specific era with specific materials, and a chimney sweep who doesn’t know that will miss things that matter.

Why Top Hat Chimney Is Commack’s Preferred Chimney Cleaning & Sweep Company
Ask anyone on your street. That’s not a slogan; it’s how a company that’s been working the same communities since 1999 builds a reputation. Wendell Pike still answers his own phone more often than not, and the sweep who shows up at your door is background-checked, in uniform, and accountable to a name you can look up.

Commack homeowners have been burned by the phone-quote-then-door-price routine. We don’t play that. The number you hear on the phone before a single tool comes off the truck is the number on your invoice. Freeze-thaw damage, shared flues, cracked clay tiles: we’ve seen the recurring problems in this town for nearly three decades, and we’ll tell you plainly when a chimney just needs a routine sweep versus when you’re looking at a relining job that can’t wait.

Our Chimney Cleaning & Sweep Services in Commack
Level 1 Inspection
A Level 1 inspection is what happens every time we clean a chimney in Commack. We check the accessible portions of the flue, the firebox, the damper, and the exterior crown and joints. For most Commack ranches and capes with a wood-burning fireplace, this level is appropriate, provided nothing has changed about how you use the fireplace or what type of fuel you burn.
But here’s the Commack wrinkle: if your home had an oil burner converted to natural gas, we’re going to recommend moving beyond Level 1. The liner questions that matter in this town don’t show up on a basic visual inspection.

Level 2 Inspection
This is the inspection we push hardest in Commack, and here’s why: the post-war homes here were built with clay-tile liners sized for high-BTU oil furnaces. When National Grid extended natural gas service through central Suffolk, thousands of homeowners converted and left the original oversized liner in place. That liner was never meant for a modern gas appliance. A Level 2 inspection uses camera equipment to see down the entire flue, and in Commack it’s not an upsell. It’s the only honest way to know whether your liner is still safe.
A Level 2 inspection in Commack typically runs $275-$450 depending on the chimney’s height and access. If you’re buying or selling a home here, or if you’ve converted from oil to gas and never had the chimney looked at, this is what you need.

Creosote Removal
Creosote builds up in every wood-burning chimney. How fast it builds depends on what you burn and how you burn it. In Commack, where plenty of homes still run wood stoves as primary heat through the winter, we see heavier creosote loading than in towns where fireplaces are just decorative. First-degree creosote is a brush job. Third-degree is a glaze, which takes mechanical removal and sometimes chemical treatment.
A routine creosote removal in Commack runs $189-$275 as part of a standard sweep. If you’re burning green wood, burning with the damper choked down to stretch overnight, or running a wood stove daily from November through March, you need this done more than once a year. We’ll tell you honestly what interval fits your burn pattern.

Soot Removal
Soot removal is lighter work than creosote removal, but it still matters, especially on gas fireplace chimneys and oil-to-gas converted flues. Gas appliances produce a fine, acidic particulate that eats at clay tile liner joints over time. Commack’s converted furnaces push that particulate through oversized liners, where it lingers and concentrates. A soot removal service for a Commack gas fireplace typically runs $150-$225.
If you’ve converted from oil to gas and haven’t had the chimney cleaned since, the soot left behind from the oil years doesn’t just go away. It’s still in there, and it still needs to come out before a proper camera inspection can tell you what condition the liner is truly in.

Trusted Brands We Service in Commack
When a Commack chimney needs more than a sweep, Wendell’s crew installs and services equipment from brands that hold up to Long Island weather: DuraFlex for stainless liners, Copperfield for chimney caps and chase covers, and Famco for dampers and cleanout doors. We keep common parts on the trucks so most Commack repairs don’t mean waiting on a shipment. If you’ve got a Copperfield cap that’s rusted through after an Atlantic winter, or a Famco damper that won’t seat, we can usually handle it the day we look at it.
Common Chimney Cleaning & Sweep Problems We See in Commack Homes
- Oversized liners left over from oil-to-gas conversions. Commack homes built between 1950 and 1975 had chimneys sized for high-BTU oil appliances. Natural gas burns cooler and vents less volume, so the original oversized clay liner never gets warm enough to draft properly. That leads to condensation, acid etching on the tile, and eventually liner failure. We flag this on almost every Commack job.
- Shared flues in 1960s colonials. A significant number of Commack builders ran the fireplace flue and the oil-burner flue through the same clay tile liner. That was never code-compliant, and it creates backdrafting that pushes smoke and carbon monoxide back into the house. Finding this turns a routine sweep into a code-compliance conversation.
- Freeze-thaw mortar erosion. Central Suffolk winters bring repeated crossings of the freezing point, with wet Atlantic air soaking into mortar joints that then freeze and pop. The crowns and joints on Commack’s aging masonry chimneys spit bricks and crack grout faster than the rest of Long Island. We catch it during spring inspections, after the damage is done and before it gets worse.
- Heavy creosote in wood-stove homes. Commack homeowners who burn wood as a primary heat source, or supplement through the winter, load their flues faster than the once-a-year schedule assumes. Third-degree creosote glaze is common in homes off the main roads, where stoves run hot and long.
Pricing for Chimney Cleaning & Sweep in Commack, NY
A standard chimney cleaning and sweep in Commack runs $189-$325 for most single-flue homes. That includes the sweep, creosote or soot removal, and a Level 1 inspection. Add a camera-based Level 2 inspection and you’re looking at $275-$450 total, depending on flue height and access from the roof.

Liner relining work in Commack, when needed, typically runs $2,800-$5,500 depending on liner length and diameter for a single flue.

FAQs - Chimney Cleaning & Sweep in Commack
Because your chimney was built for oil, not gas. Commack’s post-war homes went up between 1950 and 1975, with clay tile liners sized for high-BTU oil furnaces. When natural gas arrived via National Grid’s expansion into central Suffolk, thousands of homeowners converted while leaving the oversized liner in place. Modern gas appliances vent cooler, less forceful exhaust that never warms those big clay tiles enough to draft properly. The result is condensation inside the flue, acid etching on the tile, and slow but definite liner failure. That’s why Wendell recommends a camera inspection on virtually every Commack chimney cleaning job where an oil-to-gas conversion has happened. Call (631) 502-3612 to schedule a Level 2 inspection and know for sure what shape your liner is in.
Once a year, burn or no burn. Chimneys break in the off-season too. If you run a wood stove as primary heat in Commack, burning daily from November through March, you may need sweeping twice a season, especially if you’re burning less-than-fully-seasoned wood or running the air control closed overnight to stretch a load. Heavy creosote loading is the single most common issue we see on Commack wood-stove chimneys, and it shows up faster here because stoves run long and the outside air is wet. First-degree creosote is a brush job. Third-degree is a glaze that costs more and risks a chimney fire every single burn. If you’re not sure where you fall, schedule a sweep and we’ll tell you honestly what your burn pattern requires.
Shared flues, full stop. A significant share of Commack’s 1950s and 1960s homes were built with the wood-burning fireplace flue and the oil-burner flue dumping into the same clay tile liner. That violates current code, creates backdrafting that pushes smoke and carbon monoxide back into the house, and should have been corrected decades ago. We find it most often in homes that haven’t had a professional chimney cleaning since the original oil furnace was pulled out. The fix is usually a full reline with a DuraFlex liner and a dedicated flue for each appliance. Wendell will show you the camera footage and explain it in plain English, every time, no exceptions. Call (631) 502-3612 to schedule an inspection if you suspect your home is one of them.
Yes, and it’s worse here than you’d expect. Commack sits in central Suffolk County, where Atlantic-influenced winters bring repeated crossings of the freezing point, often several times in a single week. Water soaks into the mortar joints and the crown, freezes, expands, and pops small pieces loose. Do that a few hundred times over a winter and you get spalling bricks and cracked crown edges, which let more water in and accelerate the cycle. Homeowners who skip an end-of-heating-season inspection usually don’t notice until a chunk of brick falls or a leak shows up in the attic. Spring is the right time to have Wendell look at the crown and joints before summer thunderstorms push more water in. One call to (631) 502-3612 gets you scheduled.
Expect the sweep to take roughly two hours, with the house left as clean as we found it. We lay drop cloths around the hearth, run a high-powered HEPA vacuum at the firebox, and brush the flue from the roof or from below depending on your roof pitch and access. On Commack ranches, we’re also checking the attic chase, the crown, and the visible mortar joints, because these homes are 50 to 70 years old now and freeze-thaw damage doesn’t announce itself. After the sweep, Wendell walks you through what he found. If it needs more, you’ll see the camera footage and hear the plain-English verdict. If it doesn’t need more, he’ll tell you that too. Call (631) 502-3612 for a free estimate, and the price you hear is the price on the invoice.
