Over a season that residue turns into a hard coating of creosote, plus soot, ash, and sometimes debris carried in by animals. Left in place, this buildup restricts airflow, sends smoke and carbon monoxide back into your rooms, and becomes the fuel for a chimney fire. Our cleaning removes all of it. We scrub and vacuum the flue, the smoke chamber, and the firebox until the surfaces are clear, then we check that your chimney draws the way it should. You get a fireplace that lights easily, burns cleaner, and heats your home the way it was built to. If you are simply keeping up with yearly upkeep, our routine [Chimney Sweeping](https://thechimneyprofessionals.com/services/chimney-sweep/) service covers the annual visit. A cleaning is the deeper job for chimneys that have gone a while, smell smoky, or show heavy buildup. - 20+ Years in Business - 1,000+ Chimneys Swept - Free Estimates - 24/7 Emergency Service [Book a Cleaning](https://thechimneyprofessionals.com/contact-us/) WHAT WE REMOVE ## Everything Fire Leaves Behind ### Soot The fine black powder that coats the flue walls, dulls your firebox, and drifts into the room every time you open the damper. ### Ash The loose residue that settles in the firebox and smoke chamber and starts to block airflow when it piles up. ### Light to heavy creosote The flammable coating that hardens in stages. We handle Stage 1 flaky soot, Stage 2 crusty buildup, and Stage 3 glazed creosote, the thick tar like layer that is the most dangerous and the hardest to remove. ### Blockages and nesting debris Twigs, leaves, and nests left by birds and small animals that trap smoke inside your home. ### Staining The dark residue and buildup on the firebox and flue that a routine pass leaves behind, cleared so the surfaces are truly clean. OUR PROCESS ## How We Clean Your Chimney 01 ### Inspection We start with a camera and a visual check of the flue, smoke chamber, and firebox so we know exactly what buildup we are dealing with. 02 ### Protection We lay down coverings around the fireplace and set up containment so soot and dust stay out of your living space. 03 ### Cleaning We scrub the flue and chamber with professional brushes and rods, then break down heavy and glazed creosote where it has formed. 04 ### Vacuuming A high powered vacuum pulls the loosened soot, ash, and debris out of the system so nothing is left behind. 05 ### Final Check and Certificate We confirm the chimney draws properly, walk you through what we found, and issue your certificate of cleanliness and functionality.

Chimney Professionals did a terrific job cleaning my two wood burning fireplaces in a Manhattan brownstone. They came within one day. Their equipment is state of the art, and it was all done in less than 30 minutes. Everything kept spotless. The price was right too. 1 Mar 2026 ### M. J. Not only did they answer right away, they had Rod at my door first thing Monday morning and sourced a hard to find part same day when others could not. They beat every other quote I got and had our system back up and running in under an hour. 27 Oct 2025 ### Bruce S. The chimney in my 115 year old brick rowhouse had a badly deteriorated terra cotta lining. Michael gave me a fair price, was punctual, and while spending more time than he expected, stuck to the original price. Kudos to Michael for getting a tricky job done. 2 Nov 2025 ### Jim S. Mike and his team are phenomenal. Very quick to respond and schedule and then more importantly, absolute professionals. Deep cleaned the chimney and made sure they cleaned any residual dust around the area. 13 Nov 2025 ### Ryan L. Our building needed three new liners for each apartment.

If you burn wood often or have not cleaned in several seasons, you may have heavy creosote that calls for a cleaning sooner. ### What is the difference between cleaning and sweeping? A sweep is the routine annual pass to keep a chimney maintained. A cleaning is the deeper job for chimneys with heavier soot, creosote, or blockage that need more than a quick service. ### How do I know my chimney needs cleaning? Common signs are a smoky smell, poor draft, black soot around the opening, or smoke coming back into the room. A camera inspection confirms the buildup. ### Is chimney cleaning messy? No. We cover the area, use containment, and vacuum as we go, so the soot leaves with us and your home stays clean. ### How long does a cleaning take? Most residential cleanings take one to two hours, depending on the size of the chimney and how much buildup has formed. ### Can you remove glazed creosote? Yes. We handle all three stages of creosote, including the hard, tar like glazed layer that standard brushing alone cannot clear. ### What does chimney cleaning cost? Chimney cleaning cost depends on the condition of the flue, and we always inspect before we quote. The price is driven by: Buildup stage - light annual soot, dense second-stage creosote, or glazed third-stage creosote that needs rotary cleaning or chemical treatment. Chimney type and height - fireplace, furnace, or boiler flue. Blockages - nests, debris, or collapsed liner sections. After the inspection you get a free written estimate, so you know the exact chimney cleaning cost before we start. A Certificate of Cleanliness is included with every job across NYC and Long Island. ### Will I get proof the work was done? Yes. Every cleaning ends with a certificate of cleanliness and functionality for your records. ### Do gas and wood-burning chimneys need different cleaning? Yes. Wood-burning and gas chimneys collect different deposits and need different service: Wood-burning flues build up soot and creosote - the flammable residue behind most chimney fires - and need mechanical sweeping. Gas and furnace flues collect corrosive condensate deposits and debris that block venting and can push carbon monoxide back into the home. We clean both types across NYC and Long Island and adjust the equipment and safety checklist to your system. ## Ready for a Clean, Safe Chimney Clear out the soot and creosote before your next fire.
