You know if you've got two built in appliances (washing machine and tumble dryer in our case) and you have a spacer between them - basically a piece of wood to match the other units, only a cm or so wide? Is that what it's called. Anyway, ours is buggered, damp leaked in to it and it's expanded and split. Is it possible to replace just that little bit of wood or do I have to get a new kitchen?
