I damaged one of my attic roof trusses by accidentally knocking out a large knot from the main cross member. Although it seems sound, I think that the strength of the truss has been weakened. If I want to add a sister repair to the truss, how should I do it?
While planning our kitchen remodeling, we found out that the last owners extended one corner of the kitchen over what was a service porch. Should we have the contractor remove the porch and extend the house's foundation each way to cover the corner or just leave the porch as is? How much does it cost to add about 6' of foundation?
