Last yr I installed laminate floor in kitchen, and left the required space's
for expansion.

This yr I had a new door installed and the jam is wider, the door(sill) sit
into the room further, and now there is a need to cut the already installed
floor with out takeing it up so I have the required gap for expansion. I
need this gap not only for the expansion but to installed the transition
strip, where the floor end and meets the door sill.

The door is 6 ft wide, any ideas?

Thanks
Tom
