Hi all just after a bit of advice please. As pics show some white mould spots in patches in my living room suspended floor. The floor is double boarded with tongue and groove on top and standard floorboards underneath that. No visible dampness or major smell. The previous laminates were down for 20 years on top of a thin foam underlay. Is it worth trying to lift some of the boards for further inspection? Ive tried from one end and they are not even budging which could mean they have been glued down previously. Or clean treat and place new flooring? Thanks very much.
