I mentioned before about wanting to install some insulation below my living room windows before getting new upvc windows and before fitting a rad below the windows . I stripped the skirting away to get me access for the foam material but there was evidence of wetness from one existing window where the pointing was defective . I also removed several carrier bags of earth and debris from behind the skirting ( Gawd know why it is there ..must have been dumped there when the building was built about 100 years ago) and some of it below the defective pointing was wet and had obviously been retaining the moisture . I sawed out a couple of pieces supporting the wooden panelling ( Glasgow Victorian tenement) and the end of the final floorboard and wire brushed the next board where the last 3-4 inches was crumbly ....I might yet saw that part off as it is behind the panelleing and there will be no weight placed on it and it is well enough supported by the next joist .
Having done this and with ( hopefully) the new windows stopping the water ingress is there anything I need to do with the timber in that area ,like spray with some sort of treatment ,or have I done enough not to need anything ?
