Brett B is an excellent technician. He is professional and did a great job inspecting and cleaning my dryer duct. On a previous job he built me a custom dryer duct. It works perfectly and makes inspection and cleaning quick and easy. I recommend him for all my duct work. He is easy to communicate with and gets the job done. Capitol duct cleaning is the one to go to for all duct work.

Brett and Matt at Capitol Duct cleaning went above and beyond to help me today. Not only did they accommodate my schedule due to upcoming travel (thx to Amy too), they cleaned, and sealed my air ducts, and also helped troubleshoot how to best condition my crawl space to mitigate mold when the water table gets too high. They are top notch professionals, and just absolutely delightful people to work with. I will absolutely work with this company again!

5 stars is not enough!! From the first interaction with Amy over the phone and beyond, I had a wonderful experience with Capitol Duct Cleaning. I had initially scheduled a duct cleaning for my new home, but when they went in with the camera it was discovered that I had a few ducts that needed replacement. The technicians, Brett and Sean, were wonderful and provided me with quotes that same day for the replacements.

They were very honest and provided me with a few different options, which was very appreciated and refreshing. I cannot say enough good things about the team at Capitol Duct Cleaning! They have me as a customer for life.
