Since 2001 Bill Marko, Builder has been a successful family owned and operated carpentry/ contracting business. BMB specializes in the building, repair, and restoration of barns in the residential, commerical and agricultural markets, as well as the design, construction or repair of decks, garages, and workshops. If you're renovating or repairing an existing building, there are some very important considerations. There are a lot of New England structures that are 100+ years old. Repairing these without destroying the integrity of the structure or your budget takes careful planning and workmanship.
