Commercial pressure washing in Fontana that actually works around your hours. Very good work overall, though the noise during business hours was a factor.

The parking lot was slick with grease and now it is safe to walk on. Good result overall. One section of the lot needed a second pass.

Work was fine. Communication was poor throughout. They did not cover the landscaping and some plants were flattened.
