Chimney Cleaning
Our chimney cleaning service removes dangerous creosote buildup to prevent fires and carbon monoxide intrusion. We use professional-grade equipment and follow CSIA-certified procedures to ensure safety. Clients receive a detailed 12-point inspection report with visual documentation.
Gutter Cleaning
Professional gutter cleaning prevents water damage to foundations and roofs. Our team clears debris, checks downspout functionality, and identifies potential repairs. We follow CDC safety protocols to eliminate ladder-related risks during service.
Slate Roof Repairs
Specialized slate roof repairs preserve historic properties and maintain structural integrity. Our technicians replace damaged shingles, renew flashing, and install snow guards while preserving original architectural details.
Duct & Vent Cleaning
Comprehensive duct and vent cleaning removes allergens and fire hazards. We clean dryer vents to reduce fire risk and HVAC ducts to improve indoor air quality using commercial-grade disinfection protocols.
Chimney Inspections
Level 2 chimney inspections use ChimScan technology to identify hidden structural issues. Our certified technicians check for cracks, water damage, and animal intrusion while providing repair recommendations in easy-to-understand terms.

Report
Michael and Matt from Clean Sweep were wonderful to work with. They helped us with all of our fireplaces. Michael's expertise is evident in how he explained all of the details one needs to know to operate their fireplaces safely and confidently. We look forward to working with Clean Sweep for as long as we live here and will most certainly refer them to our friends and neighbors.
Luckily the previous owners of our home suggested we use Clean Sweep because they do a GREAT job and he was right.

I called Clean Sweep to discuss issues regarding the work they did to my chimney one year ago. Two weeks went by with no phone call. Today I called to follow up and my call went to voicemail, but the voicemail box was full! I recommend that you look elsewhere. With something as safety critical as a chimney, you need a company that you can trust. Your life depends on it.

I had a last minute real estate need and these guys stepped up big time! I called them at 9 in the morning and they were able to come out and inspect my clients chimney by 3 pm. Their workers were professional and knowledgeable, taking the time to explain what they had found to my client. Their report was user friendly and clearly explained what the issue was. Absolutely would recommend them.

Honest and prompt service. If you have any chimney issues, call clean Sweep. I called another company (ace of diamonds) and they told me it needed $2000 of work. Clean Sweep told me they could do that work but it isn't necessary because nothing will happen either way. I'd call them again in a heartbeat if there was a problem.
