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!

Thank you for sending Brett, Dominic, Joey, Lucas, and Matt!!

Had a couple days of crawl space work done on both my home and my rental. All of the young men who worked here were very polite and professional. They were quite pleasant, communicated clearly, hard-working and teamed together very well. Appears they enjoy what theyre doing! Both households are looking forward to enjoying improved efficiency and I happily look forward to recommending Capital Duct Cleaning to everyone I know!

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.

The folks at Capitol Duct Cleaning provided excellent service. I was able to talk through possible issues I was experiencing with the appointment specialist and the appointment was scheduled to take place within a few days. The technician informed me of his expected arrival time. When he arrived he was friendly, professional, and very knowledgeable. I would definitely recommend their services. Thanks, from a satisfied customer.

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!

Reece and Lucas showed up on time, did a walk through and worked efficiently and professionally to get the multitude of ducts cleaned and sanitized in our 3000 plus square foot home. They took before and after photos, taking the time to explain things we can do to improve the air quality of our home. I was very impressed with these two gentlemen. The office staff that I worked with we very responsive to our urgent need to get this cleaning accomplished. I would highly recommend them to potential Clints.

Communication was super clear. Multiple texts and emails were sent a few days leading up with reminders of the appointment time and directions to make everything go smooth. When the tech was on their way, I got a link to track the location to know exactly when they would arrive, which was really great. Technician was nice and easy to talk to. Service was done thoroughly and very quickly.

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.

Capitol Duct Cleaning was able to come out same day and clean the dryer vent of our newly purchased home. Brett, the technician, did a thorough job cleaning out the ducting and then went the extra mile to troubleshoot why the dryer was not pumping out much air through the clean duct. He even inspected our crawl space! I highly recommend Capitol, and especially Brett! I would use them again! And I will!

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.

This company was truly great! They have the best price out of all the companies that work in the Tacoma area. Once they completed the job they didnt leave any mess or deposits from the hoses and cables. They were outstanding and will recommend them to anyone who needs their services. Thanks again for your hard work!
