Raise sunken joists

[jbgall]

I am trying to raise sunken joists ( home not built to code ) The crawl space is hopeless. I am thinking of going through the floor from the top. Has anyone done this?

Sounds like you need a contractor to put some footings in and re support the floor and possibly replace some of the floor joists. This can be done from the top. A job like this needs to be evaluated by a qualified contractor.

Once you finish all the structural repairs you should look into the CleanSpace systems for crawlspace encapsulation. You can call us at 1-800-541-0487 for a dealer in your area.
