I just installed some DuPont glueless laminate flooring in my kitchen (about 120 square feet), and I have a quick question. I followed their installation guide (made sure the floor was level, left 1/4 gaps around the edges, sealed the edges with flexible silicone, etc.).

I noticed yesterday that there are two spots where there seems to be "soft spots". What I mean is, when you step on these spots, the floor gives a little bit, like it's not resting on the floor underneath. Both of these spots are where the same two rows of laminate are joined together. I've had the floor installed for about a month now and I just noticed this yesterday (though it could have been there before). Also, the temperatures here in Detroit have recently started getting hotter.

Is this normal for floating floors, or is something wrong? If something needs repair, how would I go about fixing it? Unfortunately, I already installed all the quarter-round molding all the way around the room so taking the floor up would be a major undertaking.

Thanks in advance for any information.

I would bet that either there is a low spot in the subfloor at that point or the laminate planks were/are bowed a little. IMO, and after installing floaters since the 80's, seems like on every job there is usually one spot where there is a little flex in the floor. Not bad mind you but not the same as the rest of the floor. And in time when the furniture has been put back, the floors typically feel fine. Just my opinion and experience.

Keep an eye on that spot or sit a straight edge on that spot, to see if it is raised up, like it is buckling.

If it raises anymore, it's locked in and grown to take up the expansion space you left. Do you have heavy furniture opposit each other across from this boncey spot?
