Hi there, My husband are I are buying our first home. We found an updated home built in 1958. We had our house inspection this weekend and the biggest issue that came up is a crack in the main girder in the basement. The inspector's comment read "Cracked main girder section noted in heating closet in basement, needs proper repairs to same by qualified building contractor.." I understand what the main girder's role in the house is, but am wondering how this can be replaced/reinforced. Is it a major job? How costly is it? The attached picture is the picture the inspector took. Thank you!
