Keeping Hawaii Clean Since 2001


Cornerstone has serviced many of Hawaii’s Parking Garages. This work is a dirty job and we are equipped to clean it. Whether it’s a build up of car oil in the stalls or all the dust that accumulates over the walls, pillars, overhead pipes, etc., our equipment can squeeze under 6 foot 1 inch of clearance to maintain your parking facility.


We pressure wash with 240 degree hot water to remove the toughest of stains. In order to be compliant with the EPA, we capture all of our water run off with a vacuum and berm systems to avoid wash water from entering into any surrounding storm drains.


We work around the clock to meet your scheduling needs. Give us a call to see how we can help maintain your parking facility.
