Keeping Hawaii Clean Since 2001


Cornerstone has assisted many construction companies in the maintaining of their heavy equipment. Clean equipment makes it easier for the maintenance technicians to find leaks along with being more efficient and pleasurable to work on.


When shipping Heavy Equipment pressure washing is a must to clean tires, tracks, engine compartments etc. to remove rocks, dirt, and debris. Let Cornerstone partner with you to get your equipment successfully through the docks and on to the next destination.


We have helped many clients get their heavy equipment ready to be sold by providing professional cleaning to aid in the presentation to potential buyers.


Cornerstone Pressure Washing has a trailer with a large water tank providing our services even in areas that don't have water accessible.


We can also make a wash pit to satisfy EPA guidelines if there is not one on the job site.
