What is the easiest way I can level these dips on both sides of this room without ripping the main floor out ???
Thank you ...In the Bush
The 3/4 hardwood probably helped provide support that kept the other side from sinking as much.
Need more info.
Are you saying you have an 8-foot interval between your floor joists?
What is your subfloor made of? How is it constructed? Is it 2x tongue-and-groove over 8-foot spans?
If so, you could probably put down a good layer of plywood (3/4-inch?) and then "float" your floor using a floor leveling compound. It wouldn't be an elegant solution, but it would probably do the job.
I'd sure consider going underneath and adding some support. If you don't want to crawl around, cut a hole in the subfloor to get at it.
