Sean was a total pro - thorough, timely, and friendly. He took great pride in his work and offered to send us before and after photos. Thanks so much!

I was amazed how fast their moss treatment starts to work. The blow off and clean up included removal (off my property) of tree branches on the roof from the early winter storm. They won't leave the job until I'm satisfied and all my questions answered.

Michael did a fantastic job! He kept me informed throughout the process. I highly recommend Johnny Tsunami for reliable home maintenance.
We had our roof, solar panels and gutters cleaned.
From estimates to job completion, everyone was professional and knowledgeable.

Jack Valdez is a lean mean cleaning machine! On his first as Lead, and single-handed at that, he did an outstanding job involving routine and advanced glass cleaning, soft washing and pressure washing. The house is transformed and ready for Spring! Jack is a hard worker and totally professional. A genuinely nice young man as well. He is clearly a future Leader in your company! Well Done!

Johnny Tsunami goes above and beyond. Service technicians are always nice and knowledgeable. Alex did a great job on pressure washing my house and cleaning the windows and gutters. No pressure tactics, and always looking out and letting me know about foreseeable problems. I truly appreciate that.
