What customers say

My backyard looks like new today; We are doing barbecue much more often now.

Mark, Sunnyvale

They came out within 24 hrs (in the pouring rain) to give a quote. They showed up on time, worked promptly, and the results speak for themselves. It was everything you expect but seldom get in service.

Todd Wilms, Menlo Park

Amazing! Very conscientious, punctual and left everything sparkling!

Lisa, Episcopal Church of the Epiphany

Ivan and his crew at Slon are tremendous. We are now using their services at all of our businesses. A+++!

Kevin Goswamy, Applewood Investments

The best part, there are no chemicals used and no wastewater going into your neighborhood creek.

George, Cupertino

Questions and answers

How is this different from just washing it myself?
We don't just spray all the dirt off into the corners, we take it all with us. Our tech is much more effective than any ordinary pressure washing.
Power washing & pressure washing. What's the difference?
Power washing has one key difference: Hot water. We heat up our water to (230°F) in order to remove tougher stains that ordinary pressure washing can't.
How long does the process take?
It varies, usually we can get any job knocked out in a day.
How should I prepare before the cleaning?
There shouldn’t be any cars on the driveway or furniture on any surfaces that would interfere with our cleaning.
Do I have to be there?
We recommend you to be home for the initial estimate in order to understand your concerns around your home. You don't have to be present for the actual job as long as we access to your home.
What if it rains?
Is there a hurricane warning in the news? If not, we're in business.
Do I need to provide a source of water?
We bring our own clean water but it would be great if we could also fill up on clean water at your location.
Am I allowed to take photos/videos?
Absolutely! We encourage it.
