Buckling hardwood strips

Hello,

Just moved into a house and noticed some of the wood strips are buckling. Just slightly, but it can feel a bit spongey when you walk on them.

Iíve tried putting weights on them in the hope they would sit down better. Didnít work.

Could I try a small finishing nail or two?

House is a very open concept bungalow and I donít think the structure standards of 1978 (build date) are up t the task. Basement is fully finished so nothing can be done from below.

Is the floor a nail down or floating floor?

Buckling usually means moisture is present. Tell us a little bit more about your floor make up, where the buckling is happening, Is there a subfloor issue in that area? Need to find the reason behind the buckling before you can figure out the solution.

How do I figure out floating vs nailed. Itís prefinished 3/4Ē hardwood. I would assume nailed.

Maybe buckling is the wrong term. Hollow spots underneath?

There are a lot of gaps too. Maybe fit 2 quarters.

Looks like a poor install combined with weak subfloor supported by long 2x10 joist runs based on 1978 building code.

If you have air vents cut into the flooring you might be able to see something by pulling the grill.

Does the flooring run parallel or perpendicular to joists?

#1, Post a picture.
Lot's of things can cause this depending on what try flooring it is.
Flooring installed over particle board, water damage, flooring installed with no expansion gaps on the outer walls, ECT.

Still think we need to determine if this is a floating floor, nail down or glue together. While the pics show the problem, it doesn't give us enough information to go on. If it is nail down, look at the boards that are close to the wall along the long side of the boards. They would be face nailed in the first or last 4 or 5 rows. You would be able to see where it was nailed.

If you can see the underside of the sub floor and it's nailed you should see lots of em!
