Musty smell in listed building ground floor

without actually looking at the property its impossible to say exactly what is causing your issues, ventilation under the floor only helps if its a suspended wooden floor & should have been installed at the time the floor was replaced if it was required, the main thing here seems to be why was there wet rot as replacing things without actually solving the cause will only result in it re occurring which may very well be what is happening.your best bet would be to get a specialist who understands older buildings & the materials used to construct them in to have a look for the solution. good luck Alex

This does annoy me the public are always the ones that get hurt was it a Damp Company who Did the wood Floor /Cowboys Right This Should have Been the Procedure 1) Clear the old wood Flooring 2) The Spray empty floor Area with woodworm Killer 3) Drill out the internals wall be very careful as it could be single Brick 4) Install air vents as required 5) Install 5x4 tantalized supporting timbers with noggins 6) Install the new flooring I hope this Helps you Regards Chris
