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 Commack’s Preferred Chimney Cleaning & Sweep Company
Commack didn’t grow gradually. It went up almost all at once between 1955 and 1975, when the Long Island Expressway opened the land to tract developers who built the same colonials, ranches, and split-levels block after block. That means your chimney has the same bones as your neighbor’s, the same aging clay liner, the same freeze-thaw cracks starting at the crown. We’ve been inside enough of them to tell you what’s wrong from the driveway. That local repetition isn’t a knock on the town; it’s an advantage for the sweep who knows it. Ask anyone on your street about the last time a national outfit sent a stranger who changed the price at the door. That’s exactly why we publish Wendell’s name and license number, answer every call with a live person around the clock, and put the 90-Day Done Right Promise in writing on every job.
Our Chimney Cleaning & Sweep team serves the whole town, from the Burr Farms area north of Jericho Turnpike down through the neighborhoods south of Veterans Memorial Highway. We know which streets run oil heat, which ones converted to gas in the last decade, and which fireplaces burn wood all winter. That’s the kind of knowledge you only get from an owner-operated shop, not a rotating franchise crew. When you call for service in Commack, the crew that shows up is background-checked, in uniform, and accountable to a man who lives with his reputation in the same county you do.
Our Chimney Cleaning & Sweep Services in Commack
Level 1 Inspection
Every standard cleaning in Commack includes a Level 1 inspection, which checks the readily accessible parts of the fireplace and flue. Given the age of the town’s housing stock, this is where we most often spot the first signs of clay liner spalling and cracked mortar joints. If your chimney was built between 1955 and 1975, a Level 1 is the minimum we’d recommend before the first burn of the season, and it’s included in the sweep price we quote on the phone.

Level 2 Inspection
A Level 2 inspection is the right call after an oil-to-gas conversion, a new insert, a chimney fire, or a property sale. Commack’s original clay liners were sized for oil furnace exhaust, and when that furnace leaves and a gas unit or wood insert takes its place, the flue often fails code. This inspection uses camera equipment to look inside the liner, and we show you the footage. If there’s damage, you’ll see it with your own eyes before anyone asks you to spend a dollar on a repair.

Creosote Removal
Wood fires in Commack produce creosote, and the stage determines the job. First-degree creosote is a brush job. Third-degree is a glaze, and it often means a chemical treatment or mechanical removal that takes longer and costs more. In older fireboxes, we regularly find heavy buildup where the smoke chamber narrows, especially in homes where a previous owner burned unseasoned wood. A standard sweep in Commack runs $189 to $289. Glazed third-degree creosote removal can run $350 to $500 depending on how far up the flue it extends.

Soot Removal
Oil-fired furnaces in Commack leave a sulfurous soot that’s different from wood creosote. It’s acidic, and over decades it eats at mortar joints. When a house converts from oil to gas, the new appliance often vents through the same flue, and the existing soot and liner condition become a real issue. We remove the soot, inspect what’s underneath, and tell you plainly whether the flue is safe for the new setup or needs relining. The camera footage and a plain-English verdict, every time, no exceptions.

Annual Sweep
Once a year, burn or no burn. Chimneys break in the off-season too, and Commack’s freeze-thaw winters crack mortar even in chimneys that see no fire. An annual sweep catches that early, before water gets in and turns a $100 crown repair into a $2,000 rebuild. We book annual sweeps out through the fall, and the earlier you call, the more flexibility you have on scheduling.

Fireplace Cleaning
Full fireplace cleaning means more than the flue. We clean the firebox, smoke chamber, damper, and glass doors. If you’ve been burning pressed logs, which leave a waxy residue, expect the job to take a little longer. Your flue doesn’t care how the fire looks. It cares how it breathes.

Trusted Brands We Service in Commack
We install and service liners and caps from brands we trust, including DuraFlex, Olympia Chimney, Famco, and Copperfield. When a Commack job needs parts, we don’t order blind from a warehouse and hope for the best. We carry common components and know which DuraFlex liner sizes and Famco cap configurations fit the typical 6-inch clay flue in a mid-century split-level off Burr Road. That means less waiting and fewer surprises on the invoice.
Common Chimney Cleaning & Sweep Problems We See in Commack Homes
- Spalled clay tile liner pieces blocking flue gas flow. In the 1955-1975 colonials and ranches that define Commack, original clay tiles crack over time and pieces fall into the flue. Those pieces restrict draft, trap carbon monoxide, and can ignite creosote. This is the most common finding we flag during a routine sweep.
- Eroded brick and cracked mortar crowns from freeze-thaw cycling. Commack sits inland enough to avoid direct salt air, but Long Island winters repeatedly push temperatures across 32°F. That cycling opens hairline cracks at the crown, water gets in, and the liner deteriorates faster. Homeowners often smell the result in the living room as a musty odor in the summer.
- Undersized 6-inch clay liners after oil-to-gas conversion. This is the big one in Commack. The original liner was sized for oil. Gas appliances often need a different flue diameter or material, and when the conversion happens without a reline, draft suffers and carbon monoxide risk goes up. A Level 2 inspection catches this, and local building codes will not ignore it.
- Third-degree creosote glaze in heavily used fireplaces. We see this most often in homes where a wood stove or insert was added decades ago and burned hot. The glaze is hard, flammable, and a brush won’t touch it. It needs mechanical or chemical removal, and the cost reflects that.

FAQs - Chimney Cleaning & Sweep in Commack
Because nearly every chimney in Commack was built in the same 1955 to 1975 wave, with the same 6-inch clay tile liners from the same suppliers, venting the same oil furnaces. Those liners are now 50 to 70 years old, past their rated service life. During cleaning, the brush dislodges loose tile pieces, revealing spalling at the smoke chamber offset. It’s predictable because the town’s housing stock is uniform. The failure pattern repeats street after street. Call (516) 968-5380 for an inspection and we’ll show you the camera footage before recommending anything.
We stop the standard sweep and tell you. Third-degree creosote is a hard glaze that a brush won’t remove. It needs chemical treatment or mechanical removal, and in Commack it usually runs $350 to $500 depending on how far up the flue it extends. The tech will show you the buildup on camera, explain the fire risk in plain English, and give you a written quote before any additional work begins. You’ll never wonder if we found something after the fact.
Yes. Once a year, burn or no burn. Chimneys break in the off-season too, and Commack’s freeze-thaw winters crack mortar and crowns even when no fire burns. An annual sweep in Commack at $189 to $289 is cheaper than a $2,000 crown repair or a failed Level 2 inspection during a home sale. We’ll inspect the liner condition while we’re in there, which matters more as your chimney ages past 50 years. Call (516) 968-5380 to book.
It changes what we’re looking for and what the code requires. The original 6-inch clay liner was designed for oil exhaust, which is cooler and higher-volume. Gas appliances run hotter but with lower volume, and the liner may not be sized or rated correctly. During cleaning, if we find spalling or cracking, a Level 2 inspection is almost always required to document the flue before the gas appliance can run safely. If the liner fails, a DuraFlex stainless reline typically runs $2,500 to $4,500 in Commack. Call (516) 968-5380 and we’ll walk you through what your specific setup needs.
The smoke chamber offset, where the flue narrows from the firebox, followed closely by the concrete crown cap. In Commack’s 1955-1975 colonials and ranches, the clay tiles at the offset spall first, dropping pieces into the flue. The crown erodes from freeze-thaw cycling, letting water in. Summer heat then expands the moisture and widens the crack. Both failures show up on camera during a routine sweep, and both are cheaper to fix before winter. Call (516) 968-5380 for a free estimate.
What Commack Homeowners Should Know Before the First Burn
Here’s the thing about a 1960s chimney in Commack: it’s not a mystery. It’s a known failure point. The original clay liner was undersized for the way you use the house now. The crown has been through sixty winters of freeze and thaw. The firebox has seen decades of oil heat, wood fires, and maybe a gas insert. A routine cleaning in Commack almost always turns into a conversation about liner condition, and that’s not a sales pitch. It’s the reality of a town built in a single wave, with chimneys now well past their designed service life. Last week we swept a split-level off Burr Road in the Burr Farms area where third-degree creosote had glazed the firebox and smoke chamber after an oil-to-gas conversion with no liner update. We pulled the Famco cap, ran the camera down the 6-inch clay flue, and found spalling tiles at the smoke chamber offset. We closed out with a written reline quote using DuraFlex and a Copperfield flashing repair. The homeowner saw every frame of that footage before we asked for a decision. That’s the way it should work. That’s the way Wendell has done it since 1999.
If you’re in Commack and your chimney hasn’t been looked at in more than a year, call (516) 968-5380. A live person picks up. You’ll get a flat price, a real arrival window, and an honest answer about whether anything needs to be done at all. If it’s not right, one call brings Wendell back. That’s the 90-Day Done Right Promise, in writing. Seniors and veterans always save 10%. And if a competitor already wrote you an estimate, bring it to us. We’ll give you a free second opinion.
