Safe, Thorough Moss Removal for Your Entire Property

Our service removes grime, moss, mildew, and years of weather wear without damaging your home.

Why Moss Removal Actually Matters

Whether it’s on your roof, driveway, or back deck

Here’s what unchecked moss can do:

In the Pacific Northwest, moss grows fast — on roofs, patios, sidewalks, retaining walls, fences, and siding. It may start as a patch of green, but it quickly becomes a problem that damages surfaces, traps moisture, and creates safety hazards.

  • Erode roofing materials and curl shingles
  • Crack concrete and shift pavers by holding water
  • Make walkways, decks, and stairs dangerously slippery
  • Create a rotting layer on wood fencing, stairs, and trim
  • Lower curb appeal and property value

What's included in our service?

This isn’t just a surface wash. It’s a full-property moss removal and prevention process, tailored to each surface.

The last time I hired someone to do our windows they came out to give us a quote, came back at scheduled time, completed the window cleaning job and it was great. This experience has been very different with Johnny Tsunami. This company missed our appointment for a quote, missed the first scheduled appointment. Couldn't complete the exterior portion of the job the first time they came out because our water was turned off but instead of calling me they called their office and by the time I was talking to the individual who was at our house he tells me he already left because he had another job so then I have to call AGAIN to schedule a fourth time to be at our house and then he leaves without installing all the screens back on. I get a response that this is so mold doesn't grow? This should be an option for the customer to choose because now we need to reinstall all the screens and I'm so irritated by this because we do not live in the home anymore and renters have now moved in because it took this company multiple times and days in between to "complete" the job.

We paid $3,000 for 2 workers for 4 hours to clean and treat our roof, clean gutters and to wash some exterior windows.
For the effective cost of $350 an hour, they cleaned the gutters, washed windows and sprayed the roof, leaving all of the moss to eventually die and blow off. We expected for that price, the moss would have been removed. A subsequent inspection by an independent roofer said that the work was unprofessional and ineffective, especially in the areas of the roof valleys.
Johnny Tsunami has offered the option of paying them more to brush the moss off or they will return “after the dry season to blow off any remaining moss”.
Photos submitted to the company, showing condition of roof after treatment. Johnny Tsunami has been courteous in their responses, but adamant that we should not have expected the roof to be cleaned off for the $3,000 that we paid for a half a days work by two workers.

I signed up for them to clean my gutters once a year. Since then it has been a incessant stream of requests to rate them online, refer them to a friend, etc. Texts, emails, phone calls. I've had computer viruses that weren't as bad. So here's your review Johnny Tsunami.

The guys did a great job cleaning our roof and gutters. There was a lot of debris from the winter storms, so it took some extra effort to get everything clean. Thanks for the great job!

Michael Crawford and his assistant Wyatt did an amazing job on an old house with a metal roof that had 8 years of delayed maintenance. They stayed nearby 2 hours over the estimated time to finish the job. We are beyond pleased. This is the second time I have hired one of your crews to do roof and window cleaning and again I am impressed with the level of experience and intelligence they bring to the job. I’m happy to recommend your company to others. Thank you!!

We had roof/gutters cleaned, windows cleaned, outside whole house cleaned and pressure washing done. We've lived here 20 years and have never had such professional/excellent jobs done. The house looks brand new. Wish there were more than 5 stars to give this company!
