Testimonials
“I have been in the commercial real estate business for 35 years. As the Vice President of Property Management for a mid-sized commercial real estate company, my team and I work with a variety of different building contractors on a daily basis. OneService has from the beginning, delivered on their promises. Their staff are both trained and supervised. Their turnover is low and management is always available and responsive to our needs.”

“I am the facility manager for a high-end private school with a campus of several buildings. We have contracted OneService for a number of years as our custodial service. They are consistent and make every effort in delivering a quality service. I highly recommend them.”
Facility Manager – Multiple Building Educational Facility
“I am the facility manager for a international defense contractor. OneService was on-site when I accepted the position. At the time, I was not familiar with them. I am happy to say they are a valued part of our organization and my daily routine. Unusually, I am not interested in being a reference for a vendor, but with OneService, I have referred several industry colleagues in the past.”

A big thank you to the OneService Team for their prompt and outstanding support in handling a recent security incident at our facility. Your presence truly gives our associates peace of mind and a strong sense of safety.

I know you usually hear from me when we have some issues but I also want to provide a praise report for the new cleaning team from ONESERVICE.
The change over is dramatic in the best possible way. I’m at Roosevelt this morning and the level of clean is meeting and exceeding the expectations and requirement. Back in November, the dust situation was so bad that I was personally vacuuming the floors to back of house, now not a dust mite in sight.
In addition, the set up and organization of the team at ONESERVICE is also second to none. The bathroom now looks like a proper space with health and safety in mind.
Thanks team for the support and looking forward to keeping this as the standard forward.
