If they are redoing the whole house, then it's time to go through and seal off every "little" hole that they find. Remember it's doesn't have to be very big for a mouse or rat to get through. You could use foam sealent where you go down the walls, but I've seen mice eat at that too, may be a little silicone would work or steel wool will keep them out too.
