Hello
I hope someone can help me - I have lived in a 1930s end terrace for just over two years, after first six months or so front room (north facing) smelt fusty - gradually got worse in winter. It has a reclaimed maple wood floor that I can't lift to see under but when I moved my bean bag all was green mouldy underneath where in contact with floor. Skirting appears to have tide mark of condensation type mould and some wood furniture also green / grey dusty mould. When I have had something stood on floor for a while e.g. large plant in pot or sorage chest - wood floor also seems swollen / slightly damp underneath. small patch of water damage on floor seems to randomly go wet again when it feels like it. The interior door is rarely shut and windows open reasonably regularly although the room is not in use as much as others due to this problem existing.
This is the case all round the room - even adjoining neighbour wall - not just exterior facing one???
actual wet patch just an inch above skirting on wall under bay window in winter - now gone after exessive heating and ventilation of room.
in addition to this room under stairs cupboard (smells & inside door mould) and other areas in house ground floor also show signs of condensation style dusty mould but these are not areas like kitchen / bathroom or condensation traps so I cant follow the usual advice re reducing moisture??
I dont know where to start as I have been warned about getting damp proofing injecting when that is not the real problem. As I said - not sure if I can even get under the floor as it is glued tounge & groove maple.... I fear I have let the problem go on long enough and it is starting to affect my furniture.
Help!!!
P.s. sorry to ramble!
