Hello,
I need to level a 100 year old floor in a 1st floor bedroom. We have established there is no structural issue, and the joists have just settled. I need to take up some boards and make sure there is no rot, but assuming not, I think I have a few options. I wanted to see what people here think.
I will be taking up the floorboards to reveal the joists and at the end replacing with floor ply (or any other good suggestions?), as it will be carpeted. I will then recycle the nice floorboards in a new kitchen extension downstairs. As far as I can see these are my options:
1) Shim the joists with cuts from joist length (ish) 2b4, glued and nailed down, remembering to account for difference in ply depth vs old board depth. Ply then nailed on top.
2) Sister the joists with 2b10, nicely level, remembering to account for difference in ply depth vs old board depth. Sistering with glue and nails. Ply then nailed on top.
3) Replace the joists with new 2b10 or similar with new joist hangers (beam situation dependent!). Ply then nailed on top.
4) Lay a new set of joists in between the old ones (leaving old in place), with new joist hangers (beam situation dependent). Ply then nailed on top.
What are your thoughts? And should I lay insulation while I am there (for both sound and heat)...even though its between floors I feel I should do it while I'm there!
Cheers
