I am a newbie here with posting so bear with me. I have an old craftsman era 1924 with charm but old bones. I am homeowner without building experience. I am meeting with hardwood floor man today but really interested in underneath to start and assume he will have opinions. I will take bids but want ideas and may share some here shortly.
The there are two timbers with significant cracks (out of a knot) and some slight sag. This is followed by a good timber then one more impacted by clean air duct "alteration" work, where they cut a joist and blocked to the apposing joists one either side. (Each of those two joists looks good).
I am thinking that each of the joists needs to be married with new Timber and bolted. I will not do the work but will want it done right... Any thoughts on shoring up the old bones? How do you get weight to transfer correctly? How much correction can be made in sag before upstairs floor starts to shift? My floor guy will have strong opinions here I assume.
