In 1977, Vincent B. Spiezio Jr., son of first-generation Italian American welder Vincent B. Spiezio Sr., followed in his father’s footsteps and founded a piping company called Mid-Atlantic Mechanical.

Who is Mid-Atlantic Service 360°?

For over four decades, this family-owned and operated business has thrived under three generations of Spiezio leadership, growing from a small trade company to a robust, modern mechanical contracting firm.

As Mid-Atlantic Mechanical expanded, so did the need for a dedicated service department. In 2015, the company launched Mid-Atlantic Service 360°, a managed-for-you commercial services group that provides premium tailored maintenance solutions for businesses of all sizes across the Northeast, from mom-and-pop warehouses to the country’s largest financial firms.

At our family-run business, we strive to make everyone we work with feel like family, and it shows in the number of customers and employees who have stayed with us for years, even decades.


Welcome To The Service 360° Family

Our commitment to quality service and strong relationships means you can count on us to be there for you 365 days a year, whenever you need us — because that’s what family does.
