Just installed an attic ladder in 90 year old house. Plan is to use attic for storage not for living. Currently the joists are 2x4â€™s ( real 2x4â€™s not 1 Â½ x 3â€™s). What should I do to reinforce them? I was thinking of taking 2x4â€™s and screwing them , on their sides , to the old joists and covering with Â½ plywood or OSB.
Any problems with that plan?
Spans are not huge, nothing bigger than ten feet unsupported, I think.
