Company History

The founders started United Mechanical with a simple plan: keep strong values, hire skilled people, and focus on steady quality. Over time the company grew into a regional contractor trusted for large projects. Their portfolio now includes installations that follow LEED Platinum and WELL standards and plumbing work that uses solar heating and grey water systems.

The culture centers on careful work and long-term relationships with vendors and contractors. That approach helped the firm move from small commercial jobs to complex projects with large square footage.
