When I moved into this house in 1998, there was a lot of work to do, including shoring up the living room floor which would travel an inch or two when bounced. Since it wasn't posing any immediate problems, it got put off.
Not long ago we noticed a crack in the living room wall (click any picture to enlarge):
Then this appeared in the office (in line with the living room wall):
Hm, guess we better think about fixing the floor.
The house is rather, um, homemade. The substructure is actual 2x4 redwood that is not necessarily well-assembled. Under the living room the 2x4s are just stabbed right into the dirt, and the dirt is quite soft. The living room is also the largest room in the house and eventually became known to our guests as a bit of a trampoline, having tamped down the 2x4s. We took an investigative crawl under the house to confirm what I already knew, and snapped a few pics:
Yes, that's at least an inch clearance between post and beam.
At least this fine piece of support carpentry is still holding up the kitchen. Likely because it's actually standing on concrete:
On the plus side, several years ago I had the house bolted to the foundation (which it hadn't been for 90ish years). Here is one of the custom brackets installed:
This piece is about a foot wide.
The Saturday after Thanksgiving, we donned our dust masks and crawled under to work. Here's a workout for you: Travel 30 feet prone, using just your elbows and toes, pushing a 20 pound concrete block in front of you. Travel 30 feet back the same, minus the block. Repeat 10 times.
For each block, we needed to create a level spot for it to sit. If the dirt wasn't super soft, it was hard and rock-like, requiring pick-and-smash action in close quarters.
About 28 hours worth of work later (split between the two of us) and we now have a firm, secure floor. Here is one row of new and improved supports:
And another row:
There were a few more pictures, but they didn't come out very well. The super fine dust, sketchy lighting, and awkward positioning make photography a challenge. But I did drag out a couple of pieces to shoot in the backyard. Witness the state of these "footings":
And for your amusement, some found objects For some reason, there were a lot of salad dressing jar lids.
Shasta soda, Durkee's Famous Dressing and Meat Sauce, and a prescription box for vaginal suppository. What's THAT doing under the house?
Our elbows were pretty much toast after all of that. At least it was a pretty cheap project. Yay!
