Pressure Washing, Steam Cleaning, and Kitchen Exhaust Cleaning in San Bernardino, Los Angeles, Riverside, and Orange Counties

Since 1996, Underpressure has been serving commercial clients in a wide variety of projects: shopping centers, loading docks, amusement parks, and even a giant sculpture. We believe business is personal, and our commitment to personal service has been the driving force behind our continued growth and loyal customer base.

When you choose Underpressure, you’re choosing peace of mind. That’s because we are:

• Environmentally Compliant:

• California takes the Clean Water Act (CWA) seriously. Did you know that if the power washing company you hire violates the CWA, you – the property owner – can be held liable?  Even first violation fines can be in the tens of thousands of dollars!

By hiring Underpressure Powerwashers, you can rest assured we take every step necessary to protect your environmental liability. Not only have we been environmentally certified by the Power Washers Of North America, staying informed of EPA changes is a vital part of our business.

We use only environmentally-friendly cleaning products, and are regularly researching new products to improve cleaning efficiency.

Insured and Trained:

Unlike many pressure washing companies, we carry two million in general liability insurance, one million in vehicle insurance, and worker’s compensation. All of our technicians are trained and tested, and undergo extensive continuous training. We are also members of the Independent Maintenance Contractors Association (IMCA). While our training helps ensure your property is properly cared for, you can rest assured that if an accident does occur, you are covered.

• Variety of Projects and Services:

• While Underpressure specializes in building washing and flatwork and we service a number of large retail chains across four counties in Southern California, we have been called on to do a number of more unusual jobs. We also provide more specialized services, such as indoor vacuum recovery, graffiti removal and power sweeping.

• Nationally Recognized:

• Nationally Recognized: Underpressure was featured on the cover of Cleaner Times Magazine in May, 2010, and mentioned in The Pressure Cleaning Marketing Bible. Co-Author of the “Bible,” Allison Hester, writes that Underpressure “has a strong reputation for quality and environmental compliance.”

• Community Focused:

• We believe in giving back to our community, which is why we donate our services and resources. For example, we recently cleaned and power washed the Apple Valley Museum and Art Gallery at no cost. We also support The Children's Miracle Network and the Victor Valley Community Hospital Foundation.
