History of Excellence


Since 1903, the W. B. Guimarin team has maintained its commitment to being the best mechanical contractor in South Carolina, serving our customers, employees, and the community with integrity and innovation. We continue to grow and prosper by consistently providing value to all.

We provide a full array of mechanical services for our customers. We contract on both a direct basis to the end user and an indirect basis through a general contractor or construction manager.

The services we provide are strictly mechanically oriented. We have the capability to design, estimate, and construct new, expanded, and/or renovated projects to achieve the owner’s cost, schedule, quality and performance expectations. We offer both maintenance and service to serve our customers needs once projects are completed.

Our name is well respected in our marketplace as being a quality contractor with a proven history of successful performance. We are committed to becoming recognized as the Mechanical Contractor of Choice by owners, contractors and designers throughout our marketplace.
