I need advice how to redirect and reinforce the attic stairs. We will have to leave them down, because my daughter and her baby's rooms will be up there. My problem: they're shaky,and there isn't but 18inches between them and the wall. My daughter is a heavy (190) teenager. My brother is an invalid on a cane, so it's hard to get by there for him. That's his quickest way out of his room to the rest of the house, front, back, and side doors, livingrm, kitchen and dining rm.At the moment I have turned the den into a bedroom for my daughter and her baby. But the space is limited there. So is our income, we only have Social Security. Help! Help!
