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!

Was really impressed with capital duct. My ducts were really leaky and after the guys were done doing the aerosealthe leakage was reduced down to 10sq inches. The guys were clean, timely and professional and talked me through the entire process. I would definitely recommend this company to my friends and family. And will have them come back next year to do my duct cleaning.

Brett and his colleague did a fantastic job taking care of my dryer vent line. They even took care of an issue at the end of my vent line on the roof I had not been aware of for almost 20 years! Capitol Duct Cleaning was wonderful to work with and had excellent customer service. I will never go back to the other company I used in the Lacey area.

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!

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!
