Good work, Dylan! Dylan's work definitely shows. Both the house & shed roofs are so clean now. The house's 30 year roof is 20 years old. As I looked today, it looks like a new roof! And he cleaned ALL the windows. It's so nice to look outside through them.

Michael was polite, professional and diligent. He was a good communicator and did a fine job of roof/gutter/window cleaning at our cabin in the woods. Highly recommend.

Johnny Tsunami has serviced the roof and siding of my house for years. If they weren't an exceptional business I wouldn't use them again nor write this review. JP listened carefully to what I wanted and then assessed what the house did/didn't need. Within a week Alex spent 4+ hours meticulously blowing, scraping, and soft washing the roof. He did this in very cold lightly raining weather! The roof looks great and its life has been extended.

The gentleman named Jack. Did an amazing job for us. Our roof looks new again. All the peaks in the roofs had moss control on them and all the leaves and branches were cleaned off and taken away. Very pleased with this young man’s service. Thank you Jack!

I had my interior and exterior windows and sliding glass doors cleaned yesterday and am extremely pleased with the results. Ty J. did a fabulous job. He arrived on time, was friendly, courteous and professional. I will be hiring them again to do my siding and deck cleaning. I highly recommend Ty and Johnny Tsunami.

Dylan and Dalton did a super thorough job cleaning my roof, gutters, windows, and decks. They arrived on time, worked quickly, and took me through a final walkthrough to make sure everything met expectations. Great work!

The service and attitude of Laura and Bobby were excellent (front end). It didn’t feel like the service end was 5 star.
