When remaking low -quality repair, all work on it has to be carried out again — remove the finish, carry out wiring, putty walls, sell new recesses in the walls, and so on. Small repairs will cost the owners, of course, cheaper, but there will be no guarantee for it — no one knows that it is hidden deep under the finish. The full alteration of the room will cost more, but it will give a guarantee of quality — after all, the workers will be rebuilt again.
