We purchased our home this past winter in Northern NJ. Our den area has a floating laminate floor that looks like it was installed in the past 2-3 years and is in good shape. However, we just noticed that in one area of the den a couple of the boards are buckling upward, and have at least 1.5 inches of separation from the subfloor. I’ve searched for solutions for a buckled laminate floor online. The two most common causes appear to be water damage or expansion of flooring improperly installed too tight to the exterior walls. The floors have not been wet, so I suspect that the latter is the main cause.
What would you recommend to repair the buckled laminate floor? The area is actually closest to our fireplace and there appears to be some chipping at the edge of the floor at the fireplace.
