I have a 1936 built house, with parket type flooring in the hallway. The
flooring is laid onto floorboards, and is made up of varyious sizes and
patterns. The flooring is starting to lift. What can I do. I would
ideally like to take it all up and re-lay it, although it will be a hell of
a jigsaw!
How should I best relay the floor - can I use an insulative base - and what
sealant / glue should I use?

Many thanks
