We have had service from Johnny tsunami for a number of years now and have never been disappointed! They do a great job and Are true experts at what they do. Today’s technician, Jude, went well above and beyond any expectations. He explained exactly what happens to your roof with mold, Lichen and moss. He then explained what their techniques are and what their products do. He did a fantastic job!

The service from Johnny Tsunami is 1st class. My last appointment was with Jayce White. I was informed when the team is on the way to my house. Other issues were pictured and texted to me. The roof cleaning solution works very well. the windows were cleaned to perfection. I cannot see the gutters, but they do not overflow from a hard rain, so, the gutters must be cleaned well also.

Whyatt M and his team member did an excellent job cleaning the windows inside and out of our two story home. The windows have never looked better. Very pleased with their professionalism on the job and the quality of the work they performed. Those two represent the business well. We have tons of windows in our home and they all look great.
