About Us

Commercial Wash + Seal LLC

Commercial Wash + Seal LLC first started as Cape May County Powerwash (1996) out of Sea Isle City, NJ, and then was known as Brian Hemphill Powerwash (2000) up until 2015 when we rebranded to be more in line with our other service companies. The company started by powerwashing houses, decks and exteriors of buildings, and then expanded into exterior painting and deck watersealing. We now service residential, commercial and municipalities. We can provide 24 hour response for any service.


Since 1996 we have serviced thousands of commercial, residential, industrial and municipal clients throughout the tri-state Delaware Valley. We've seen just about everything.
