I have sommer click style laminate flooring in the house. It extends from the living room through to an extension on the back of the house. I suspect it was layed at the same time the extension was built. Anyway as the extension has settled slightly, it has caused the laminate flooring to move, leaving gaps between some of the panels. How easy would it be to take up and relay the flooring. Alternatively would I be better just filling the gaps?
