Don't just take our word for it. Here's what Seattle homeowners say about One and Done Wash.
"Andrew was very easy to communicate with, he also helped me buy a chimney cap as it's missing from my roof and installed it besides the roof cleaning. His price is decent, and his attitude is the difference maker. I would recommend."
"We hired ONE and DONE for gutters and roof cleaning and are very happy we did so. Drew explained the process properly and showed up right on time. He did great job cleaning and provided us before and after pictures. The difference was amazing. I highly recommend this company!"
"Drew did a fantastic job removing moss from our cement stairway and landing."
"Came out quickly and was working hard when attacked by wasps! Nevertheless, stayed at the site to direct the exterminator in order to get rid of the problem. He will be coming back to finish. What a pro!"
"Drew showed up on time and did a fantastic job cleaning our gutters! He was careful around our plants below, blew the deck clean after and put away the hoses how he found them. The price was very reasonable and we will definitely hire Drew back for gutter cleaning in the future!"
Proudly serving Seattle and the surrounding Puget Sound communities.
