Solid Hardwood, Engineered and Laminate Flooring - Laminate Floor Bounce

Is it normal for a laminate floor to have a slight bounce to it on the edges near the walls? I just put it in today. It is Pergo with a vapor barrier and cork underlayment. The concrete slab floor was pretty flat with no issues when laying the tile, and all joints are secure with no popping sounds. I did leave a 1/4" gap at the side and end of each plank for expansion. It really does look great.

I've read elsewhere that a slight amount of bounce is normal with laminate flooring as they are floating floors and not glued or nailed down, but just wanted to verify with the forum.

Thanks!!

Get the trim molding on and push it down tight, while your standing there. There really should not be a bounce, unless there is a high spot your bridging, or spaning a low spot.

I haven't put the new baseboards on just yet. I'm replacing the old with 5" boards, so they should cover up the gaps nicely. I'm noticing the slight movement no matter where I step on the floor, and I did check the floor for a level surface before starting.

I'm thinking that it could be the 1/2" cork in conjunction with the underlayment that was already attached to the Pergo Accolade flooring.

As I said, the movement is very slight and there is no popping or shifting in association with the movement. Should I be worried about this at this point?

By the way, the 1/2" cork was used to bring the concrete subflooring up to the level of my ceramic tile. I checked with a couple of flooring stores and they said that I shouldn't experience any problems by doing this, as the cork was a solid underlayment for laminate. I've also researched this forum and found a few that had stated that placing laminate with underlayment attached over cork was not a problem.

Any additional thoughts/comments are appreciated.

Thanks!

The Floor Guy is correct. In the 3 rooms I did, there was a certain amount of give at the edges until I installed the trim (quarter round in my case). Be sure to stand on the flooring when installing the trim and press the trim down firmly when nailing. BTW, cork underlayment is considered by many to be the best underlayment for floating flooring. It was too expensive for me, though. :)
