Moss Removal pricing depends on several key variables:

  • Roof condition (severe moss = more labor and chemical application)
  • Treatment area (partial or full roof coverage)
  • Type of roof (metal, composite, tile — all require different approaches)
  • Height, pitch, and overall accessibility

Soft Washing pricing is based on the total surface area cleaned and whether you’re treating siding, driveways, patios, fences, or concrete surfaces. Our process includes a low-pressure application of eco-safe solution, rinse, and optional preventative Moss Control. We’ll inspect your property and help prioritize what services bring the best ROI.

Most single-family homes pay between $200 and $350 for a full Gutter Cleaning service. This includes removing debris, flushing downspouts, inspecting flow, and cleaning the exterior of the gutters (if requested). Larger homes, multi-story buildings, or properties surrounded by tall trees and heavy debris may cost more.

We recommend cleaning your gutters at least twice a year — especially in spring and fall — to prevent clogs, water damage, and costly repairs. Overflowing gutters can compromise your roof, siding, and foundation, so staying ahead with proactive care is essential.

Yes! Johnny Tsunami offers bundled service packages that reduce overall cost and increase convenience. Common bundles include:

  • Roof + Gutter Cleaning
  • Gutter + Siding Washing
  • Whole-home Exterior Clean + Windows + Decks

Bundling different exterior cleaning services saves you money and ensures a more efficient service visit. Our teams coordinate the work across services, saving you time and, hassle, and giving your entire home a refreshed, professional look in one go. Bundle and save while maximizing your property’s appeal.

Our MX Plan is a hands-off, peace-of-mind program for proactive homeowners. We tailor each plan to your property’s layout, tree coverage, and roof condition. Services can include:

  • Annual or biannual soft wash roof treatments
  • Spring and fall gutter cleanings
  • Algae and moss prevention services
  • Siding wash-downs and driveway treatments
  • Window cleaning add-ons

Members enjoy priority scheduling, 15% off services, and regular reminders so you never miss essential maintenance. Great for busy homeowners, landlords, and HOAs.

Eventually — yes. But our professional treatment significantly delays regrowth. Most roofs stay clean for 12–18 months depending on your tree coverage, weather exposure, and drainage.

We recommend an annual maintenance plan for moss prevention, gutter flow control, and touch-up treatments. We also provide guidance on trimming overhanging trees, clearing roof valleys, and keeping surfaces dry to slow moss growth.

One-time cleaning solves the immediate problem. Maintenance plans prevent the problem from coming back.

Benefits of our MX Plans:

  • Lower annual cost
  • Auto-reminders and scheduling
  • Priority booking before the busy season
  • Long-term savings on repairs and replacements

Homeowners who join our plans stay cleaner, longer — and save big over time.

Good work, Dylan! Dylan's work definitely shows. Both the house & shed roofs are so clean now. The house's 30 year roof is 20 years old. As I looked today, it looks like a new roof! And he cleaned ALL the windows. It's so nice to look outside through them.

Michael was polite, professional and diligent. He was a good communicator and did a fine job of roof/gutter/window cleaning at our cabin in the woods. Highly recommend.

Johnny Tsunami has serviced the roof and siding of my house for years. If they weren't an exceptional business I wouldn't use them again nor write this review. JP listened carefully to what I wanted and then assessed what the house did/didn't need. Within a week Alex spent 4+ hours meticulously blowing, scraping, and soft washing the roof. He did this in very cold lightly raining weather! The roof looks great and its life has been extended.

The gentleman named Jack. Did an amazing job for us. Our roof looks new again. All the peaks in the roofs had moss control on them and all the leaves and branches were cleaned off and taken away. Very pleased with this young man’s service. Thank you Jack!

I had my interior and exterior windows and sliding glass doors cleaned yesterday and am extremely pleased with the results. Ty J. did a fabulous job. He arrived on time, was friendly, courteous and professional. I will be hiring them again to do my siding and deck cleaning. I highly recommend Ty and Johnny Tsunami.

The service and attitude of Laura and Bobby were excellent (front end). It didn’t feel like the service end was 5 star.
