Alan who posted above is the expert here, and I agree with him. Of course it is natural to think the worst, but you really will not know anything until the floor is removed.

I'll just add that a laminate floor is usually a "floating floor", installed with about a 1/4 inch gap all around the perimeter to allow for expansion, etc. This is typically covered with quarter round. If this was not done the floor could have expanded and "bubbled or buckled" in this area.

I inspected a home the other day, a new home with laminate flooring. The installer caulked all around it instead of letting it float. It looked horrible and the caulk had come away in many places due to the normal floor movement.

Once you have the new floor delivered, make sure you allow it to accumulate. When the old floor is removed check for a moisture barrier, making sure it is there and the seams overlapped and taped. If there are dips or birdbaths in the concrete slab level them with floor leveling compound. also make sure you use the correct padding, if it does not come with the floor itself.

I am not a floor expert, but have successfully installed laminate floors numerous times. I hope this helps.
