I first noticed it about a month or so ago inside the wardrobe in DS's bedroom. He has the new room that was added on to the house about 4 years ago and has two outside walls. The smell though is coming from the inside wall the joins the children's bathroom and has the shower head on it.
We've just come back from 3 weeks away and as soona s I walked in the front door, somehting smelt not quite right. When i went into the kitchen it was a softer version of what i can smell in DS's room.
It doesn't smell damp, it's not even particularly unpleasant but it's just not right and inside the wardrone it's quite strong. IF the wardrobe doors are shut you can't smell it. I can only liken it to wood, perhaps where wood is being shaved off to make it fit something. It's a tad musky perhaps.
BTW, the kitchen is not directly under DS's bedroom but very close.
Any ideas please? I'm quite perplexed what to do next. I've taken everything out of the wardrobe and I can't see anything sinister.
TIA
