uneven wooden floor solutions?

This isn't going to be simple unless you want to install carpeting over the dipping floor. Assuming the problem is on the first floor and you have a basement larger dips can be corrected with jack posts that you adjust from the basement. Other than this your problem is the result of improper sub-structure support under the sub-floor. I located a great instructional format for you to consider in correcting your problem and it includes the tools and pictures.

Just go to; Hardwoodinstaller.com

use the self leveling compound and then your floor covering, if there are heaves then you may want to belt sand the high spots and fill the low ones, make sure your floor teleposts are adjusted properly for max. level before. if you do this after the leveling compound is put down it will break and crack

its kinda a hassle BUT you could set some osb and put it down as your new subfloor OVER your wood flooring and level the osb out and then put your carpet or whatever flooring you want on top of the new 'fake' floor.

the only lasting thank you to try this's one million/2' plywood in 2 layers laid out so the seams do no longer line up. redesigning is expensive have confidence me i understand. you will basically could desire to stay with it until you may arise with the money for to do it ideas-blowing.
