Hi
Please can someone advise. I've recently bought a bungalow in which the integral garage was converted years ago to a bedroom. This room seems to get lots of condensation and can smell damp/musty. Upon further investigation, we took up the floor to find a timber floor had been put on top of original concrete floor to bring up to same level as rest of house.
But, the original concrete floor is damp so don't think this has a dpm under it and the first row of bricks is obviously damp up to DPC too. All the external walls (2) are cavity walls.
On the external skin of walls there are air bricks but nothing on the inside internal wall, so air bricks are just ventilating cavity.
So my question is do I paint something like Sinaprufe/Dry Base all over concrete floor and up bricks to DPC, to provide liquid DPM and then replace wooden floor? Or do I vent the internal wall opposite to where external air bricks are?
Or both?
Bearing in mind there's not a lot of space. There's literally the joist depth and say another inch before you hit to the original garage concrete floor. The joists are suspended from metal brackets attached to wall.
