We've just had a wooden floor laid at home (by professionals), and now I'm wondering how well the job has been done, and I'm hoping some of the experts here will be able to advise me.
It's a Bruce hardwood, engineered board, floating floor, made up of 5" planks. Most of the planks fit together perfectly (there is no groove), but at the ends of some of the planks there is a gap, wide enough to fit your thumbnail in.
My question is, should I be worried over these gaps, will they let moisture/grit in etc., or is it perfectly normal (and presumably with shrinkage/expansion gaps will change anyway)?
