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.
Chimney Cleaning Services in Commack, NY
Chimney cleaning in Commack usually runs between $189 and $329 for a standard single-flue sweep, and most jobs booked early in the week can be scheduled within three to five business days. That price should include the full sweep, a visual inspection, and a report on the flue’s condition before any repair conversation starts. If you’re in Commack and want a straight answer on cost, condition, or whether the job even needs doing, call (631) 502-3612 and Wendell or one of his crew will walk you through it on the phone.
We’re Top Hat Chimney, and we’ve been cleaning chimneys the same way since Wendell Pike founded the company back in 1999: show up when we say we will, charge what we quoted, and tell you the truth about what’s up there. Commack’s housing stock keeps us plenty honest. The homes here were built in a particular decade, with particular materials, and they fail in predictable ways a sweep who knows the town can spot from the driveway. That’s the kind of familiarity you don’t get from a call center.

Why Commack Homeowners Choose Top Hat Chimney
Ask anyone on your street. Commack is the kind of place where word travels, and Wendell has been working these neighborhoods long enough to get flagged down at the grocery store. That’s not a marketing line; it’s what happens when you put your name on the truck. Top Hat is locally owned and owner-operated. The sweep who shows up at your door is background-checked, in uniform, and works for the guy whose name is on the invoice.
We clean chimneys in the ranch and cape neighborhoods off Jericho Turnpike, the split-levels over by the library, and the older homes near the Greenmeadow and Mayfair sections. Homeowners in Commack keep calling us for the same reasons. The price we quote on the phone is the number on the invoice, no trip charge inside the county, and every job is backed by our 90-Day Done Right Promise in writing. If the sweep isn’t right, one call brings Wendell back at no additional cost. Phones are answered by a live person twenty-four hours a day, and it may well be Wendell himself picking up at two in the morning.
We also honor a standing 10% discount for seniors and veterans, and knock $40 off any repair over $200. If another company has already handed you a written estimate, bring it to us and we’ll give you a free second opinion. No pressure, no hard sell. Wendell will tell you plainly when a chimney can wait another year, and he’ll show you the camera footage to prove it.
Chimney Cleaning Services We Offer in Commack
Chimney Cleaning & Sweep
A proper Commack chimney cleaning removes creosote, soot, and debris from the flue, smoke chamber, and firebox, then finishes with a visual inspection of the liner and masonry. First-degree creosote is a brush job; third-degree is a glaze, and catching it early saves you from a relining conversation later.

Chimney Repair
Mortar joints, cracked bricks, spalling crowns, and damper issues all show up in Commack chimneys as they pass the fifty-year mark. We repair what’s failing, and we won’t recommend work the camera footage doesn’t support.

Fireplace Services
From a full teardown and rebuild of a firebox to a simple gas log placement, fireplace work in Commack comes down to the same rule every service here does: nothing gets recommended without visual evidence you can see for yourself. Your flue doesn’t care how the fire looks. It cares how it breathes.

Chimney Cap & Crown
Commack’s freeze-thaw cycles are rough on crowns, and a missing cap invites rain, squirrels, and the occasional raccoon. We install and repair both, using hardware from Copperfield and Olympia Chimney, and we’ll show you the before and after photos without being asked.
Learn more about our chimney cap and crown work by calling (631) 502-3612.

Chimney Liner & Rebuild
When a clay tile liner in Commack is cracked, offset, or missing sections, we talk you through the options: stainless steel relining with DuraFlex, HeatShield resurfacing, or a full rebuild where the structure demands it. This is the conversation that matters most in Commack, for reasons we’ll get into below.

Why Commack’s Climate & Housing Affect Chimney Cleaning
Commack is a post-war suburb in the truest sense. The overwhelming majority of homes here went up between roughly 1950 and 1975, which means ranch, cape cod, and split-level houses with original masonry chimneys now sitting at fifty, sixty, sometimes seventy-plus years old. The clay tile flue liners installed during that building boom have been through decades of heating seasons, and in Commack’s Atlantic-influenced winters, the freeze-thaw cycling is what does the real damage. Water gets into the mortar joints, freezes, expands, and repeats that cycle dozens of times each winter. By the time spring arrives, crowns are cracked and bricks are spalling, and nobody notices because nobody looks at the chimney until October. Spring inspections in Commack routinely turn up frost damage that went unseen through the entire heating season.
But the bigger story in Commack is fuel conversion. When natural gas lines expanded through central Suffolk County, thousands of Commack homeowners converted from oil to gas, and many left the original chimney in place. Those chimneys were built for high-BTU oil appliances, and the flue is often oversized for a modern gas furnace. That’s not a cosmetic issue. An oversized flue cools the exhaust too quickly, which means condensation, which means liner damage. On a chimney cleaning job in Commack, a liner-condition assessment is nearly mandatory, because the chimney may not have been properly relined when the fuel source changed. Once a year, burn or no burn. Chimneys break in the off-season too, and in Commack, the off-season is when the gas furnace is doing all the work.

FAQs About Chimney Cleaning in Commack
A standard chimney sweep in Commack costs between $189 and $329 for a single flue, with dual-flue homes running $349 to $459. The price depends on whether you have a fireplace, a furnace flue, or both, and whether the system has been cleaned within the last few years. Every quote is fixed before work starts. Call (631) 502-3612 for an exact number, and we’ll give it to you over the phone.
Once a year, burn or no burn. In Commack, the off-season matters as much as winter, because the gas furnace is running through the same flue year-round. Annual cleaning catches creosote buildup in a wood-burning fireplace and condensation damage in a converted gas flue before either becomes a fire hazard or a structural problem. If you can’t remember the last time it was swept, it’s time to call (631) 502-3612.
Not always, but the answer almost always requires a camera inspection. Commack homes built for oil heat often have clay tile liners sized for high-BTU burners, and when the furnace was converted to gas without relining, the flue is oversized. That causes condensation, which damages the tile. The camera footage will tell us whether relining with DuraFlex or a HeatShield resurfacing is necessary, or whether the existing liner is still sound. We’ll show you the footage and give you a plain-English verdict. Nothing gets recommended without it. For a free second opinion on a relining estimate, call (631) 502-3612.
Creosote builds up, and creosote is fuel. A hot fire can ignite it, and a chimney fire can crack the liner, damage the masonry, and in the worst cases, spread into the house. For gas furnaces, a blocked or deteriorating flue can push carbon monoxide back into the home. This is genuinely dangerous, and it’s not the place to save two hundred dollars. If you haven’t had a cleaning in a year or more, call (631) 502-3612 and get it done before the next burn.
Usually, yes, but the process starts the same way every job in Commack starts: with a camera inspection. A chimney that’s been neglected for that long often has more than creosote, and we need to see the liner’s condition before we run a brush through it. If the liner is cracked or missing sections, sweeping alone won’t fix it, and we’ll tell you that plainly. The camera footage and a plain-English verdict, every time, no exceptions. Call (631) 502-3612 to schedule.
If you’re ready to have your Commack chimney cleaned, inspected, or repaired, call (631) 502-3612 for a free estimate. Wendell and his crew have been working these neighborhoods for over 29 years, and the 90-Day Done Right Promise means the job gets done right or we make it right, in writing, every single time.

What Commack Customers Say
"The sweep was properly done and the report was thorough. It is a small operation though, and getting a slot in October is close to impossible. Book in the summer and you will be fine."
- Marguerite Fowles"Turns up in the hat, which the children thought was the best thing that had ever happened, and left the hearth cleaner than he found it."
- Josefina Aranda"We bought a house with a fireplace nobody had touched in a decade. He ran a camera up it, found a cracked liner tile, and told me plainly not to light a fire until it was fixed. He could have swept it, taken the money and said nothing."
- Marcus Elderidge
