Some things can be done by a novice, others need special equipment --
it really depends on what needs to be done. I can sympathize with your
difficulty in finding people who are willing to work -- feels like next
to impossible to find someone to take your money these days when it
comes to repairs. Your post leaves some open questions... maybe if you
answer some of these people can give you better advice:
- What do you mean "joist is not even touching the cinderblock"? Do you
mean the cindrblocks "tossed" on the crawlspace floor (presumably
dirt?) are sinking on their own? That would be pretty strange -- a
cinderblock only weighs a few pounds by itself.
- The main wall "has sunk 2" ..." with respect to what? Is the floor
sagging in the middle by 2", or is the entire house sinking, or what?
- What symptoms is your house showing? Floors are starting to slant?
Interior walls are cracking? Doors not working anymore? Floor beams and
joists looking like they are sagging/tilting/etc.? Foundation stem
walls cracking? Visible sinking in part or all of stem walls? Gaps
opening between foundation and walls above?
- What are the new beams for? Are the old beams (which lasted 80 years)
- If your 1926 house moved 2" in 2 years, how many feet has it moved in
the 80 years
since it was built? Do you know what changed?
Depending on your situation, soil type, etc, you might really need that
$12k job. Or maybe just digging some footers for posts/pillars under
your existing beams, and maybe some reinforcement of existing beams.
You might post a picture or two if you can...
