Can I install flooring perpendicular to a hump in floor?
 

Hello,

I am in the middle of a bedroom remodel. The subfloor is old 1x boards and they have gaps between them anywhere from 1/8 to 3/8. I am currently laying down 1/2" plywood over the existing 1x boards, glueing and screwing the hell out of it. The problem is that you can feel a hump down the center of the house. Not sure how to measure this hump to give anyone an idea how bad it is. My question is, will this hump bother our hardwood floor install? I plan on putting 5/8 solid bamboo stranded flooring down. The flooring strips would run perpenducular to this hump. So, I wonder if the flooring strips would flex enough over this hump. The fact that it's stranded bamboo worries me with flexing.

Find a peice of wood or something that will span from the side of the room to the center of the hump and then measure the gap close to the hump, do both sides.

It looks about 11/16 in 4 feet on one side of the hump and about 7/8 in 4 feet on the other side.

That's not a hump, it's a curb. The first choice is to find the cause and fix that. Can you see what's going on from under. Do the floor joists run in the same direction as the hump?
Short of fixing the whole floor, you might cut tapered firring strips to put above the floor joists and then use 5/8 t&g plywood.
Level may not be practical but somewhat straight is needed.

Not sure if it's much of an option. Damn old houses! Can we still put in the flooring. The old flooring was spruce I believe.

The worst mistake of my life was buying this friggin place! Getting seriously discouraged.

You've already covered it with plywood?
Direction of joists?

Yea, that's pretty bad, it needs to be fixed unless you go with carpeting. It'll look and feel bad with carpeting too but........

So this 1x is the subfloor? How wide are the boards?

Put a 1" spacer on each side of the room and lay a straight edge across to see if the floor is sagging or does it just have a hump.

You can install vinyl or carpet. That's about all.

You guys give up to soon, this has to be fixed evan for carpet, you can't have a 1" trip hazard in the middle of the floor!
