Superior Mechanical Services, Inc. began in 1948 as a family-owned business. In 2005, SMS was purchased by long-time
employees Jerry Williams & Joe Enos – with a vision to continue Superior’s enduring record as a quality mechanical
contractor. We are a union shop, and most of our technicians and staff have been employed with us for many years.
We take pride in our work and are dedicated to providing value-minded service with a down-to-earth approach.
