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

Love the distilled water/ no squeegee approach for window washing. the two guys were great! I would absolutely want to have those 2 technicians again. My tech's name was Whyatt.

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!

Recommend!

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