Commercial Cleaning Services

Founded in 2000, Blue Sky is an independent, veteran-owned business that provides commercial cleaning services to businesses throughout Delaware’s three counties.

The Art of Clean

Commercial cleaning projects often require entering facilities while unoccupied, respecting strict timelines, and operating security systems. Each team member is field trained and receives ongoing education on workplace safety. Our leaders understand what needs to be done in the time that you’ve allowed.

Blue Sky was born from a collaboration of Valerie & Gary Ventresca. Gary’s skills were honed as an efficiency educator & cleaning project specialist at his family’s janitorial supply company. Val’s acumen is polished by years of managing large multi-tenant properties for local developers.

Blue Sky is licensed by the State of Delaware, insured against accidental property damage, and every employee is protected by worker’s compensation insurance. We believe that it is the right way to do business.
