If you want high -quality repairs, at least you need to calculate the amount, that is, how much you are ready to spend on it. When you order a group of builders, since you yourself do not make repairs, you choose what the coating of the balcony will be (floor).
It can be a wooden coating, laminate, even kavrolin can be laid, the main thing is not to forget about the floor insulation, then everything will be fine.
