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.

Losi pressure washed my driveway, porch, and patio furniture. They did a great job! I have some drainage issues in the driveway area, and they took the time to wait for the water to drain. Previous companies have left me with a large muddy pit at the end of the driveway. It took a full day, and they stayed late and finished everything. Highly recommend this company!!

They were 4 hours late and then all they could say was Sorry. My gate was left open, and the hose was not reattached. The only saving grace was the guy was nice. I would not recommend them.

Whyatt M. and Darryl arrived early and were extremely professional. They listened to my needs and provided excellent advice.

The work was performed on-time and they even added a couple additional items that I needed free of charge.

Thanks for a job well!

Wyatt M. He was professional and explained all that was going to be done then showed pictures of the finished project. He and his helper Darryl were fast and efficient. Thank you for the great job. I can only hope all employees are as conscientious.

Hello, I thought the team did a good job and were very professional. I was a bit disappointed the sidewalks weren't washed off or cleared where the dead moss fell from the roof cleaning. Would have appreciated cleaning up around the edge of the house to remove moss clumps and dead moss. Thx.

Had roofs/gutters cleaned & washed. Also, had additional screen reinforcement around chimney top to prevent critters from coming down the flue. Shawn & Daryl started the job on the first day, they did a fantastic job in spite of not having an optimal ladder for the job site. Second day, Gavin & Daryl came out, they did a fantastic job in spite of not having an optimal ladder. Third day, Gavin came back with a taller ladder to finish the job and install additional chimney screen. He did an amazing job with everything; he’s conscientious and thorough. And as requested, he sent us LOTS of photos afterwards.
We are happy with the service the guys provided. A shout out to Gavin, Shawn & Daryl for working so hard, and a job well done!

JP was great to work with. You can tell he wants the business. Gave me a good quote, got here a little early ( said 0900 to 11 and got here at 0845 to work) and stayed till the job was done ? And it was a lot). I would recommend them to anyone!!!!!!!
