About Us

who we are

Our History

In 1979, with a pickup truck and a van, brothers Rod and Dave Williams founded EBS (then known as Williams Wash-On-Wheels) to answer a variety of service needs of Minnesota’s commercial masonry contractors.

Over the years, under the guiding principle of “quality and dependability with integrity”, the company has grown. In 1997, we incorporated and changed our name to Exterior Building Services, more commonly known simply as “EBS”. As we gained experience over the years, we also expanded our product offerings and services. Today it is among the region’s most trusted and respected contractors for the building envelope.

The EBS Difference

Quality

Expertise

Responsiveness

Safety

These are the reasons our customers tell us they continue to hire us again and again.
Our customers entrust us with their most critical projects because they know we have the expertise – and the integrity – to get the job done right, the first time. They know we’ll be there when they need us. They know we understand the importance of working together as a team to bring the project in on time and within budget.

Commitment to Quality

We understand the challenges our customers face and make sure we are doing everything we can on our end to make their jobs easier. Our customers know they can rely on us to handle their needs and get the job done right. Just tell us once and it will be handled. Period.

It is these things that have allowed us to build strong, lasting relationships with our customers. It is why repeat customers represent over 86% of our business.
