Limbach’s Mid Atlantic office is one of the few major subcontractors in the metropolitan Washington area to provide in‐house mechanical, plumbing, and electrical construction, temperature controls and engineering services. The majority of this work is contracted under a Design/Build or Design/Assist delivery method.
Our team of sales, operations, tradesmen and engineering professionals has demonstrated a consistent ability to complete projects on-time and on-budget. The Mid Atlantic Office is one of the largest Mechanical, Electrical, and Plumbing contractors in the area.
Located in Laurel, Maryland, the Mid Atlantic Office employs over 60 full-time construction professionals and over 200 mechanical, electrical, and plumbing tradesman and service personnel. Our 50,000 square foot facility includes a state-of-the-art pipe pre‐fabrication shop and office space which houses operations, BIM coordination, Special Projects construction and service staff.
“...I would also like to comment on the extreme degree of professionalism demonstrated by the contractors and our own, Howard. They were careful to see that our needs were met as they were able to work through the complications of installing the unit. They were respectful of time restraints, the limitations of our students, and the safety of all staff and students.
I simply want you to know that I appreciate all the efforts of those involved."
