I made a bit of a mistake a few years ago when I laid a new laminate floor, I covered the access to the central heating pump. The flooring was laid on old t&g wooden flooring, I now need to make the pump accessable again and what I was thinking is to cut a square out of the laminate flooring and then make a new piece that would fit into the gap, the problem is how would I do this and what tools would I need to cut the laminate flooring without cutting through the wooden flooring as well. Any help and advice would be appreciated.
