About Us
A Legacy of Service. A Standard of Excellence.
Since 1973, Professional Building Services, Inc. (PBS) has provided janitorial services that go beyond the basics. What began as a smaller business has grown into one of the region’s most trusted family-owned commercial cleaning partners — not because we scaled fast, but because we’ve always prioritized doing the job right.
Our average client retention is over 10 years — a rare number in this industry. Why? Because we price our contracts to clean, not to just win the bid. We show up prepared, we do what we say we’ll do, and we proactively resolve problems before you even have to ask.

What Makes PBS Different
We Price it to Clean it — Not Just to Get it
Our estimates are built around actual service needs, not the lowest possible number to land a contract. You get transparency, consistency, and service that holds up long term.
Operational Management is Our Foundation
You won’t find disconnected middlemen here. Our managers are trained to be in the field, available, and responsive. It’s how we stay ahead of problems, and why clients rarely have to call us.
Long-Term Relationships, Not Turnover
Many of our clients have been with us for 10+ years. We prioritize consistency, performance, and relationships.
Green Cleaning Before It Was A Widely Unused Tool
We’ve been using environmentally conscious chemicals and processes since 2002, guided by our “PBS Green cleaning policy & operating procedures" that follows the USGBL Leed-EB O&M 2009.

Leadership You Can Count On
Our senior team combines decades of hands-on experience in commercial cleaning, restoration, and facilities management. From a Porter position to Area Manager position, every detail of our operation is led by people who’ve done the work themselves.
Let’s Start a Long-Term Partnership
We’d love to hear about your facility’s needs — whether it’s nightly janitorial, emergency restoration, or specialty floor care.
