Helpful Answers. Straightforward Advice

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.

DIY is possible — but not recommended unless you have the tools, safety training, and time. Risks include:

  • Ladder falls
  • Damaged gutters
  • Incomplete flushing that leaves hidden clogs

Hiring Johnny Tsunami means fast, safe, and thorough service — plus we spot small issues before they turn into leaks, rot, or foundation damage.

Here’s what we recommend:

  • Gutters: Twice yearly (Spring and Fall)
  • Siding: Once a year minimum — more if you have trees or algae
  • Solar panels: Every 6–12 months for optimal efficiency

Regular cleaning keeps your home healthy, your curb appeal sharp, and your energy savings intact. We’ll help you build a schedule that fits your home and your goals.

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!

The windows and solar panels look great. The moss control on the roof seems to be working well.
