Company History /

Industrial Services was incorporated in 1987. As a specialty contractor, our expertise was in high pressure waterblast cleaning- 10,000 to 36,000 psi. We provided shut down deep cleaning services in automotive paint shops for GM, Ford, Chrysler, Jeep & Chevrolet, in plants across the country. Between automotive shutdowns we were contracted to provide waterblast services in oil refineries, manufacturing facilities, and with other industrial cleaning & commercial contractors. Our work has always been schedule driven, labor intensive & safety oriented. Our workforce has always worked in confined spaces, & in less than desirable circumstances, & we have always delivered. Before it was popular to be “Green”, our industrial cleaning and waterblasting operations offered our clients sustainable solutions for energy conservation and operating efficiency.

As competition became more prevalent, we soon realized we could not perform solely as a “waterblast” contractor. Over the years we continued to grow, adding ancillary industrial cleaning & vacuum truck services to our portfolio while expanding into new markets & locations.

In 2009, we began providing new construction services on industrial and commercial projects. This new construction services division is lead by Patrick Hulswitt who has over 21 years of experience in the commercial construction & industrial cleaning industry.

Today, our Ann Arbor Michigan location is the core of our day-to-day construction services operations. From Ann Arbor we deploy our new construction service crews, warehouse & ship filtration equipment & bid and manage all new projects/ inquiries within our services offered. Our Walbridge Ohio sister company, MWC Ohio, oversees our industrial cleaning service & filtration field support operations. Ideally located, our facilities are within a short drive of metro Detroit, Lansing, Kalamazoo, Saginaw, Midland, and Flint Michigan as well as Toledo, Lima, & Cleveland Ohio, & Indiana.

ISI is hardworking, honest people that take pride in their work and follow thru on their commitments. I would say the 2 best qualities if I have to narrow it down would be: 1) Perform quality work in a timely manner that meets the construction schedule. 2) Follow thru from the office to the field personnel with documents and scope change."
