Hey guys,
We have just taken back possession of our rental property and I'm in the process of gutting it after having some terrible tenants.
The house has always smelt damp and we are trying to remedy this by installing polythene under the house and removing all the gib on the external walls and packing them out by another 45mm but staggering the studs to create as little thermal contact as possible and installing closed cell spray foam insulation plus thermally broken aluminium windows. (We installed pink batts about 3 years ago in the ceiling to r6)
What I'm trying to weigh up is the OSB floor in a couple of the rooms smells extremely musty in two of the rooms is it worth trying to paint it with a oil based paint to seal the smell in or just rip the floor up in those two rooms and lay new osb?
