Historical Cleaning & Restoration


Interstate Services Group History

Built upon a legacy of service and craftsmanship, Interstate Services Group evolved from Interstate Power Washing, LLC. The firm launched in 1989 as a residential exterior cleaning company and quickly evolved into the Tri-State region’s leading power washing company. While Interstate continues to provide high-performance power washing, we have expanded our expertise to include masonry repair, waterproofing, concrete work, painting services, and more.

From maintenance and repair to total building restoration, Interstate’s experienced team supplies cost-effective solutions tailored to your most stringent project requirements. Experts in the art and science of restoration, we choose cleaning techniques and products that procure eco-friendly results.

Interstate serves commercial, industrial and residential clients throughout NJ and PA, and we own a full inventory of man lifts and high-reach equipment. This allows technicians to service buildings, multi-family housing and other structures more efficiently than most companies.
