I have built-in wardrobes in all my bedrooms and was just wondering how I can prevent/get rid of the musty smell that is the wardrobes in the two end bedrooms. I presume they are smelly because they are against the outside wall. The bedroom itself isn't musty, just the wardrobe. Could it ever be that I need to drill a small hole in the doors for ventilation to prevent this from happening again?? Incidently, I have a built in press in my Sitting Room also and I have the same problem there but the press isn't against the outside wall, it's beside the fireplace which should be nice and warm.
