Peaking Can Be Caused By Fixed Moldings

Even if there is room to expand, your laminated flooring cannot take advantage of it if the moldings cannot move. This can sometimes be a nightmare to track down if the original installer was not consistent. Since laminate flooring is intended to be floating, which means not attached to either the moldings or the sub-floor, any solid point can cause an issue. Amateur installers will occasionally attach the laminate floor to molding to keep it from moving during install, or simply because they don't know any better.
