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.

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!!

Communication was poor from the outset. We submitted a request through their website and received no response for four days. Then, without any prior notice or scheduled appointment, an estimator showed up at our home a couple of days later.

By that point, we had already hired another company. When we informed him, he seemed confused and believed he had an appointment, which had never been arranged. He explained that his manager wasn’t sure how to handle our online request and sent him out without confirming anything with us.

If something as basic as scheduling and communication is handled this poorly, it raises serious concerns about how they would manage actual work or resolve problems.

I scheduled a roof and gutter service but got stood up after doing a soft wash on my roof. Poor customer service and all I heard was excuses to why they didn't show. "They were swamped!" lol
One customer lost...
