There was been a pin hole leak just above floor level from a basin's concealed hot water feed pipe for a year since the plumbing was done and the dampness above floor level has just revealed itself. The original old joists closest to this leak seemed to be very wet. A drying out process is now going on using de-humidifiers and driers. Regardless of this drying out process am I right to assume that mould spores will live on and that these wet joists will eventually rot causing dry rot to set in? I would welcome good advice on the best action to take next before the floor covering goes back and the room is re-decorated. Martin
How drastic is the damp? Personally I would seriously consider renewing anything damaged or affected by the damp. Rather than trying to clean it up.
I am not certain but I believe that mould requires dampness, so if you dry it out, then you kill it. Mould is in any case a surface "product" and can be killed with bleach, believe you are thinking of rot which requires lots of wetness.
Ensure that the underfloor void is vented, eg airbricks not blocked or covered etc,this will promote effective drying out.
