The Mid-Atlantic's most trusted B2B directory of licensed commercial MEP contractors.
Haus of Contractors was built to solve a simple problem: finding a licensed, trustworthy commercial contractor in the Virginia, Maryland, and DC metro area is harder than it should be. General search engines return a mix of residential contractors, outdated listings, and paid ads — not the specialized commercial expertise that facility managers and property owners actually need.
We focus exclusively on commercial and industrial MEP (Mechanical, Electrical, Plumbing) contractors. Every listing is verified against state licensing databases. Every featured contractor has claimed their profile and confirmed their credentials.
All contractors listed in Haus of Contractors are verified against state licensing databases on a quarterly basis:
Contractors who claim their listing undergo an additional manual verification step before receiving the Verified badge.
