Since the founding of SMI in 1988, the company has transformed from a single trade subcontractor to one of Hampton Roads leading MEP construction companies.
As a multi-trade subcontractor we believe there is a better way to build, so we approach each project looking for ways to eliminate and minimize waste while leveraging opportunities for collaboration.
From the estimating process to on-site construction, our multi-trade subcontractor teams work together to ensure project success.
Southeastern Mechanical, Inc. has experience in Mechanical, Electrical, Plumbing, and HVAC system installations in new and renovated commercial buildings as well as commercial HVAC preventative maintenance and service.
From maintenance and repairs to diagnostics and installations, our trained technicians are equipped to keep your building safe, comfortable, and energy efficient.
We also offer preventative maintenance agreements to help ensure your equipment is working correctly to maintain peak efficiency, extend the life of your building systems and prevent utility overpayment.
Our special projects group can handle MEP improvement work, design/build retrofit or additions, and equipment upgrades or replacements.
Southeastern Mechanical, Inc. provides Mechanical, Electrical, Plumbing and HVAC & Electrical service expertise in all vertical markets including:
Our expertise is repeatedly demonstrated through core-competency services performed for a variety of satisfied customers in all vertical market sectors.
Southeastern Mechanical, Inc. considers itself one of the industry leaders in Design/Build. With many years of experience both in construction and engineering, our staff has completed millions of square feet of Design/Build projects. This is our preferred way of doing business because we view it as a win/win situation and the best construction delivery method for the Owner.
Oftentimes, the owner has hired a design team but is also looking for contractor feedback. SMI has extensive experience in Design/Assist; where the owner’s design team has begun their work, but it is not 100% complete. This method of construction can be effective when the owner is under tight budget constraints and a fast-track schedule. We step in as part of the team and offer our expertise and solutions to assist the design team while keeping tough budgets in mind. Sentara BelleHarbour
SMI has an extensive array of experience in Plan/Spec work in all markets. This is the more traditional Design/Bid/Build approach. When Design/Build or Design/Assist isn’t the right fit for the project, this is the method owners or institutions will take in order to fulfill their construction needs. 880 United Women’s Health Center
SMI has vast experience performing Retrofit projects. Whether it’s simply converting a traditional commercial tank type domestic water heater system to a tankless one, updating a chiller plant to a more efficient one, or converting a mechanical system to a more reliable one, we’ve got the answers for all your Retrofit needs.
