Putting in new en-suite
Removed tiles, sink, shower &* carpet.
some of the chipboard flooring is water damaged. I can remove and replace most of it, but about 6 inches of board comes under the stud wall. The wall runs parallel to the joists, roughly halfway between two joists. If I cut the chipboard back to the wall, the chipboard under the wall will be unsupported.
Is there any risk of the wall using the chipboard for support? (the en-suite was added at the same time as a bedroom extension - before we had the house.)
If I cut back the board, is there any (easy?) way of getting support under the wall?
Alternatively is there any sealant I can get which will soak into the chipboard and stabilise it (the water damage in this area is not too bad.)
Finally - what is the best way of protecting the floor from water damage in the future (I will be fitting aqualoc laminate flooring with a water proof underlay - I could try running that up the walls a bit.)
Thanks all.
