We have a badly installed chipboard floor in our main bedroom (joins aligned over free space, no extra noggins etc and quite a few badly made access panels for wiring and heating) so I want to do something with it.
Initially I planned on lifting it all and relaying with 22mm T&G chipboard but upon further investigation I've discovered the original floor is 20mm, not 18 or 22mm, so I'd have problems where the two stud walls have been built - the flooring continues underneath one of these walls onto the landing and under the other into the bathroom. Cutting flush might be a problem as these walls don't appear to have joists under them and if i leave the 20mm in place to the first joist out from the walls I'll have a 2mm difference where the new flooring goes down.
The joists are 6"x2" and spaced at 16" centres.
Providing I shore up the joins in the old floor with extra support would that be strong enough to allow me to lay the new flooring, say 18mm chipboard, on top of the old instead of lifting the old and trying to figure a way of getting new 22mm down?
Any other suggestions?
