My mother in-law summer house was built 4 years ago, over the years we have noticed that there is mold on the bottom of the wall leaning up to the ceiling, we pulled back the carpet and the floor boards was wet, so decided to take up the flooring in the living room area and in the office dividing rooms cos of damp and mold, i took the floor boards up and the insolation and is was soaking in both rooms, the guy that built it didn't put any DPM down on the concrete slab. So I've been told some how I've got to raise one side of the structure and take out the soaked floor timbers and replace with new timbers and put DPM down over the concrete and put new insulation on top of the DPM and then new floor boards will go on top. Will this solve it? Oh and I think I will have to take the ceiling down in the living room area cause of the mold.

If everything is soaking, you probably have a water ingress and it's not just down to lack of a DPM.
