Keeping Hawaii Clean Since 2001


Cornerstone services various businesses that require pressure washing due to their volume of customers visiting their locations. We refer to these areas as high traffic areas. We clean from end to end of the front of the store: concrete walkways, benches, trash cans, canopies, umbrellas, railings, and even floor mats.


Our trucks are flatbeds with our machines bolted down with hose reels feeding our wands and floor scrubbers, using 240 degrees of hot water to produce the very best of results. With our equipment mounted this way and experienced technicians, we are very efficient and competitive in our pricing.


Our technicians are EPA compliant with Best Management Practices while following OSHA protocols for safety. Gives us a call and see how we can save you money with our maintenance plans while receiving the best of service.
