DIY Pier and Beam Repair?

[DeAnna Henson]

Hi All,

Looking at a duplex that a foundation company has quoted ~$500/pier to tear out and replace. Looking online, this doesn't appear to be the most complicated thing - particularly because the crawl space is big enough to get under. I would think ~4-5 bottle jacks, some pre-poured 3000 PSI concrete piers/bases, shims, blocks, and a level to get this thing supported correctly.

Am I grossly underestimating the complexity of this? I know you risk damaging plumbing and more by jacking the house up, but if you take it slow and make sure you're distribution is even, seems to be the same risk as letting a contractor perform the work.

Another point - does the fact that this is DYI invalidate the work in the event of an inspection pre-sale? Assuming piers were placed correctly originally.

Eager to hear your thoughts!
