Ownership record · Maryland

Who owns Maryland’s “local” contractors?

51 home-service brands in Maryland are on Parity’s record under 37 investor groups and still advertise under their original local names. Most do not name their owner on their own websites.

Every brand below names its parent and its market; each name opens a page with sources, and an entry that rests on a third-party report or a technical link says so on that page. Brands we have not yet placed in Maryland are not shown. Parity tracks 2195 investor-owned brands nationwide.
