Terrible customer relations who calls you a liar when you bring up concerns about their service. Once they have your money they do not care about communication with you.

Professional, friendly and did a very good job, cleaning our metal roof that was covered in fir needles. They were also thoughtful about not over-taxing our well when using water.
ANGELO AQUINO was GREAT!

The windows and solar panels look great. The moss control on the roof seems to be working well.

Ty arrived on time and he plus assistant wen right to work. Ty and I walked around the house to ascertain if any obstacles exist or special handling be needed - then off to work. At the end (quicker than I expected, he again walked with me around and pointed out a few problem areas. In general, we were exceedingly satisfied with the company, Ty's professionalism and recommend use of their company.

Lane Lolagne and Quinton did an OUTSTANDING job cleaning all my windows and skylights, and blowing all the winter buildup of duff from my new Western Red Cedar shake roof! They also cleaned out all my gutters (mud, conifer needles, maple leaves and seed pods), a difficult job considering the 4 Norwegian Maples, old growth Douglass fir trees, and large Western Red Cedar trees on the perimeter of my property. These young men were extremely efficient, competent, very patient and friendly answering my questions. There are other exterior cleaners on the North Olympic Peninsula, but I will ONLY go to Johnny Tsunami for all my roof/ gutter/ window needs. Lane and Quinton, hope to see you next spring!

The initial visit was great and very informative. They let me know that there were payment plans available so I was able to secure the payment plan and schedule my appointment all at the same time. The crew that came out was great . I have a vast garden and they were extremely careful and took care of. I will say there was a lot of debris that came off the roof . They did their best to clean off the deck but I would have loved it to look a bit tidier .
Overall great job ! I will absolutely hire again.

We had a few issues with scheduling but when the tech showed up he did our solar panels and skylights in the rain and threw in a little extra for us. Definitely worth the wait.
