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.

Had a soft wash yo remove moss but unfortunately my gutter got clogged and the soft wash discolored my paint on my house. Thank god for Wyatt Assistant Manager. He fixed my gutter and someone is coming to correct the paint. He was truthful polite and it was a pleasure to work with him. I recommend him highly!

On a Tuesday morning JOHNNY TSUNAMI responded quickly sending someone to do an onsite quote. I accepted the quote and put $300 down for the work to be done the next day. When the tech showed the next day he said the job would take more work and two people and that they would be back Friday. When asked if they would honor the price quote, he said yes. No word the rest of Wednesday. I called Thursday morning to confirm they would be back Friday and she said yes. Later that day the guy who provided the original quote said it would actually cost about twice the original. I objected and ask that he check with management and get back to me. Hours later I text to find out the verdict on whether they will honor their quote. I get a text back that says I will be refunded my deposit. Failed service and a lost customer. They had the opportunity to make it right and walked away.

Chapter two - Good news: The owner/manager called Thursday afternoon to apologize for the snafu. He offered to complete the job as originally quoted. A week lost, but he states it will be done next week. OK. This is the kind of action good service organizations take - knowing how important reputation is - despite the short term costs to them. I get that things don't always go perfectly and recovery is possible. Stay tuned for chapter three, the critical follow through ...

And chapter three - a tech showed on Saturday to complete the job - ahead of the next week schedule. Michael was an amenable guy and a skilled tech, did a good job and I tipped him some. So despite a time lapse, the work is done. Good save Johnny Tsunami. Thanks.

2 nice young men washed my windows but the cleaning wasn't very good. Streaks and drips were left on my French doors and when I pointed them out, I was told they would dry clear. Obviously I'm gullible and I had to redo the doors and some of the windows myself. The screens upstairs were not put back on. All in all, I should have just cleaned my windows myself and saved the $600.

Vance did an amazing job pressure washing our back patio and walkways. On time, professional, efficient. We've used Johnny Tsunami for years across both exterior cleaning, roof treatment, and holiday lighting, and always been impressed by their work. Highly recommend!

For a company whose business is built on cleaning, they sure leave a lot of trash all over our beautiful county. The most egregious I have seen is in Chico area, where they placed around 50 illegal advertising signs in less than a one mile stretch of road. Absolutely abhorrent behavior for a local business, showing they clearly don’t care about their community.

The tech Wyatt was friendly and efficient. I appreciated the speed that he got my roof and gutters cleaned. We've used Johnny Tsunami in the last and will continue to use them.

Michael is the freakin man! Came all the way out to Marrowstone Island and handled the job professionally and efficiently. Would definitely recommend you ask for Michael, not everyone is as good as he is.

Six years ago good job. This year the techs were untrained, absolutely no communication from the office, and they destroyed the ridgecap. Basically I was charged $3200.00 for nothing and I now have a $1700+ repair bill. 👎👎👎👎👎 instead of stars.
