OVERVIEW
Keep Every Flue Clear, Compliant, and Documented
Commercial chimneys and flues carry a far greater load than residential systems. Continuous operation, larger flue sizes, and higher temperatures mean creosote, soot, and grease build faster and pose a real fire and liability risk. Regular commercial chimney sweeping is not optional maintenance for a commercial property. It is a code obligation that protects tenants, staff, and the building itself.
We sweep and clean commercial systems to NFPA and CSIA standards, then issue a certificate of cleanliness and functionality that serves as your record for fire inspectors, insurers, and regulators. We plan the work around your building operations, contain dust and debris in occupied spaces, and return every flue to safe, efficient service with clear documentation of what we found and what we did.

WHAT WE CLEAN
Commercial Systems We Sweep and Clean
Boiler and furnace flues
Boiler flue cleaning for heating plants that run through peak season, clearing soot and scale that restrict draft and reduce combustion efficiency.
Restaurant kitchen exhaust and grease ducts
Restaurant exhaust cleaning and grease duct cleaning performed to fire code, removing the grease deposits that fuel commercial kitchen fires and trigger inspection failures.
Creosote removal, including heavy Stage 2 and Stage 3 buildup
Mechanical and specialized removal of glazed and hardened creosote that standard brushing cannot reach.
Draft and smoke issues flagged during the sweep
We identify blockages, downdraft, and ventilation faults uncovered during cleaning and document them with recommended corrections.
A certificate of cleanliness and functionality is issued after every sweep, giving you a dated compliance and insurance record for each system we service.
OUR PROCESS
How a Commercial Sweep Runs From Start to Certificate
01
Site Assessment and Scheduling
We review the systems on site, confirm access, and schedule the work around your building operations to minimize downtime.
02
Containment Setup
We protect occupied areas with drop cloths, industrial vacuums, and containment methods so dust and debris stay off your floors and out of tenant spaces.
03
Inspection and Cleaning
We sweep the flue, stack, and connected components with professional grade equipment and eco friendly products, removing creosote, soot, grease, and debris.
04
Post Sweep Testing
We verify draft and functionality, confirm the system vents correctly, and note any defects found during the work.
05
Documentation and Certificate
We deliver a condition report with findings and recommendations, and issue the certificate of cleanliness and functionality for your records.

What Our Clients Say
Mike S.
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.

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.

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.

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.

They were able to come out next day and fix our gas fireplace issue. They listened to all of our concerns and addressed any questions we had while thoroughly explaining the work that needed to be done. The price was fair and upfront.
