We had Capitol Duct Cleaning out to our home to insulate both the attic and crawl space. Not only was the team on time and professional, but they did the job clean and efficiently. If you're looking for a business who will do an excellent job taking care of your home, look no further. I highly recommend them!

The technician was on time and polite. He was professional and did a good job. He asked to bring the hosing into the house one way and instead accommodated my wifes request and did it differently. The scheduler answered all of our questions and was quite helpful. We highly recommend this company.

After 6 yrs after painting my house Joey found that my vent had been painted shut and my dryer duct was disconnected. He took the time to get into the crawl space (which is more a low crawl space) to reconnect it! This will surely make my wife happy moving forward! Thanks Joey.

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.

We hired Capitol Duct to do some crawlspace work on our new home,
and are very happy with their service. Matt and Lucas were professional, the work was completed quickly, detailed photos were provided before and after, and the price was very reasonable.

My go-to duct cleaners. We have a very old house (early 1900s) and theyre very knowledgeable about the way things were built back then and how they interact with modern updates. They also take the time to explain what theyre doing and why. They work well with modern split units as well.

Matt was the best!!! He came to my home, inspected it and kindly removed a dead possum that was underneath my house that had ripped up the duct work which he then repaired nicely. He is kind and professional and I would refer him and Capital Duct to anyone in need of their services. Thank you again, Matt!!! I appreciate you!!!

We had a bird build a nest in our exterior dryer vent and I called Capitol Duct Cleaning for help. They were able to come out within 24 hours, remove the nest and clean our vent, and installed a barricade to prevent future issues. They were very thorough and provided in depth explanations. I have recommended them to all of our neighbors and will use their services in the future.
