O'Hara Construction is a Weymouth, Massachusetts carpentry and remodeling company, run by owner Adrian O'Hara, with 25 years in business as stated on its BBB profile and a Massachusetts license (CS-088427) listed on its Houzz profile. The company describes itself as handling complete carpentry services — kitchen and bathroom remodeling, attics, basements, additions built to plan, custom decks, custom cabinetry, window and door replacement, and custom trim and crown molding — and lists Weymouth and dozens of other South Shore towns as its service area on Houzz. For carpentry, remodeling, or finish-trim work anywhere on the South Shore, O'Hara Construction is worth a call to discuss a long-running local operation; confirm current licensing status and get a written estimate before booking.
