Hello all,
I'm after some tips on what to do with my garage to overcome a major damp problem. I had it extended in length last year, and a new roof put on. The roof is ply on joists, then covered with felt, then roofing felt. This seems to be watertight. The extension consisted of pouring a concrete base which butted up to the previous concrete base. The walls are brick. During construction, after the concrete was poured and semi-set, but before the roof was put on, it snowed. After construction the builder painted the concrete floor with garage paint. This has lifted over the new patch of concrete, but not on the old concrete. The major problem is that the underside of the ply panels are now covered in mould, and the damp is unlikely to be doing my tools any good either. I'm guessing the moisture is mainly coming from the concrete floor, but maybe also from the generally humid air due to the terrible weather this year. We did try to air it as much as possible through the summer. The windows and doors are double glazed UPVC.
So, what do you advise? I can try heating it (oil radiator or convection heater?) or I can try a dehumidifier, although they seem to be extortionately expensive. I'm open to any advice, as I don't want a new roof destroyed by damp...
Thanks for any input.
