Our Story:

Lang Door & Hardware was founded in 1996 by Broderick Lang in downtown Manchester, New Hampshire. Since then, we have grown into a leading distributor of commercial doors, frames, hardware, and related building specialties across New England. We support general contractors, building owners, and project teams with openings packages that are specified correctly, coordinated early, and delivered job-ready.

What Makes Lang Door & Hardware, LLC Different?

We handle more than product supply. We support the full openings scope, doors, frames, and hardware, plus specialties, with the technical knowledge needed to keep the project aligned. That includes specification support, submittal coordination, accurate bidding, and installation services when required. Our focus is simple: do it right the first time, communicate clearly, and stay responsive from kickoff through closeout.
