Thinking of renovating part of your house?  I'm a professional residential contractor/carpenter in Cambridge and I will visit your home one time for up to two hours to give you advice on any aspect of a renovation or addition.  I will help with: use of space, moving walls, choosing materials and where to get them, costs, how to work with a building department, potential problems, design ideas-- anything that you need help with whether you're thinking of doing the work yourself or hiring a contractor.  I will visit anywhere in the Boston area inside of Rt. 128.
