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

  • 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.

They did a great job on my roof, but charged me an extra $400 to scrub it rather than just wash it. That was not disclosed to me in the price that was bid.

Additionally, the job they did cleaning our windows was OK at best, they are very clearly not a professional window washing company

Terrible customer relations who calls you a liar when you bring up concerns about their service. Once they have your money they do not care about communication with you.

Professional, friendly and did a very good job, cleaning our metal roof that was covered in fir needles. They were also thoughtful about not over-taxing our well when using water.
ANGELO AQUINO was GREAT!
