My first time using Johnny Tsunami and I was impressed. I wish I had started using them years ago when we first moved to WA. Good old fashioned customer service is some of the best I have received in years. It is clear the owner invests time and resources into his people. The communication couldn't have been better. We had techs Michael Crawford and Ryan perform a number of task to include roof blow off, composition roof cleaning with their soft wash system, application of a moss cleaning solution, and cleaning of gutter faces. Michael is superb in leading the work and showing me pictures of the befor and after of their efforts. Everyone was SO polite and agreeable. You can't go wrong giving them a try. They are going to be our yearly roof cleaning service going forward. Just an awesome company doing exceptional work.

I’ve used this company now for I believe five years, and they always provide the most exceptional and professional service – we have a complicated series of studios and the house itself, which make for some odd moments in a window cleaners life, and they have handled it always with great skill and humor, and it’s been such a pleasure to work with Johnny Tsunami over the years. This year we had the please of Alex on lead with the very capable and professional Derrick as has assistant—they did a thorough (underlined) job with metal roof blow downs— gutter cleanings — deck pressure washing as well as windows in 2 studios and the house and we are extremely pleased with the results— thank you Alex

They were very responsive to my initial call to come out for estimate. Bobby Goldsmith explained the process and what we could expect and how long it would take for moss to die out after application and then disintegrate and blower wash off with weather so I knew roof would not be moss free same day.

Lane Lolagne and another associate showed up and were very polite. I liked that I received text messages when this company had someone en route. This is the first time we have had a service like this so not sure if priced high.
