In Their Own Words
“A happy customer since April 1998, DeLuca Cleaning Systems is unlike other cleaning services. With outstanding customer service, the team at Deluca Cleaning is very attentive and responsive. They go above and beyond with the owner and VP visiting our office on a regular basis for quality control.

If you’re looking for a dependable and reliable cleaning company with great cleaning, excellent customer service and good pricing, then I would absolutely recommend DeLuca Cleaning.”

“First Data has been using DeLuca Cleaning Systems since April 2015, replacing the former cleaning contractor we had for three years. They made an almost overnight improvement in the building’s cleanliness. The complaints we were previously getting from people in the building stopped and I actually had people tell me that the restrooms looked and smelled clean!

The staff and supervisors have been very attentive and responsive to my requests. I would highly recommend DeLuca Cleaning Systems. They give personal service that is hard to get with the big national cleaning companies, and they are still competitive with their pricing.”
