The Art of Clean

Commercial Cleaning Services

Blue Sky is a veteran-owned, family business that provides commercial cleaning services throughout Delaware.

In 2000, Valerie & Gary Ventresca launched a new type of cleaning service. Blue Sky uses the most effective products, equipment tech, and precise time management tools. Previously, Gary was an educator & cleaning project leader at his family’s janitorial supply company. Val’s skills were polished by years of managing large multi-tenant properties for local developers.

Unlike all-purpose cleaning services, we specialize in business cleaning.

“We called Blue Sky and asked if they could come by asap to refinish our tile floors for an upcoming visit from the company’s new President & CEO. They responded immediately and the floors looked like glass.”

“The Town of Newport and Newport Police Department have been using BlueSky since April, 2019. They took the time to get an in-depth understanding of what our needs were and proceeded to devise a cleaning schedule that not only met our expectations, but exceeded them. I appreciate that Bluesky Clean is affordable – I am always looking at ways to trim a budget and I do not need to sacrifice quality because I get exceptional value for what the town is spending.”
