repairing subflooring/sagging flooring


Hello to all, I'm a single mom trying to fix a bad problem with the least expense possible. I live in a very old house and fear the repairs may become more expensive than the money I save by living here. Thank you for the input on my recent questions. I guess i should have been a little more forthcoming with my info on my flooring. I think maybe I didn't want to hear how serious my problem probably is. When my son and I jacked up our sagging hallway we noted some serious wood rot. I'm worried that it is completely unrepairable without major work. The crawl space is about 3 foot deep down to a sand bottom. We live on an island and all of the wood deteriorates terribly plus living in the south you always have the termite factor and with my house being so old well I just know thats part of the problem. I simply can not afford a major overhaul right now and am afraid we'll end up laying in the sand some unsuspecting night under the house. Will post some pics as soon as I can. Thanks for the input. Can I brace rotten joists with new 2x8's with any real hope of it helping? The floor has dropped as much as two inches in some places and because of the rotting wood in the hall we were only able to jack it up about an 1 1/2 inches. I'm probably looking for a miracle answer that isn't possible.
... there are several areas in my home where the floor has begun to sag (its an old home built pre WW2). My son and I jacked it up and partially fixed the problem in the hallway by adding support but now it has begun under the bathroom flooring and especially the toliet. How extensive of a job is this going to be? Can anyone help? Any suggestions? I'd like to do it myself but fear it will be too much involved

We once visited a 900 year pub next to the Coventry Cathedral in England. You had to be drunk to navigate the rolling floors, and nothing that rolled could be left on the floors. My point is, wood will settle over time, and it is difficult to stop it. If, on the other hand, it is settling because of poor support or rot, that can be fixed. Areas in a bathroom are subjected to lots of water that often finds its' way to the framing. When that happens it is usually visible and can be repaired. If that is not your problem, shore it up as you did in other areas. Sometimes sistering another joist or adding bridging will make a big difference. And framing around plumbing fixtures often gets modified with little regard to restrengthening.

Properly raising and supporting a sagging floor system is no small project. The wood itself shouldn't be sagging unless its support system (foundation, piers, posts, etc) is deteriorating. Before spending time and money on the floor, I'd determine WHY it is sagging.

You're correct about this being more complex. You can't just jack up this area without dealing with the plumbing first.
As previously stated, you need to find out why this has, "begun to sag". Once the reason why has been determined, you can go about the repairs.

Could you post some pictures of the area from below, and also the hallway area that you previously repaired so we can give you better advice. BOB

Post some pictures, if you can. Above and below. I'm a licensed structural engineer with DIY house jacking experience, and I'd like a look. I wouldn't be able to seal a drawing for you, but I'm sure we all could come up with some good advice and (maybe) a game plan to DIY.
