If you have screwed your hands properly, you can easily set up a fry reglet drywall yourself. But if you prefer the more fireproof steel skeleton rather than a skeleton of wooden walls, you need to rent and rent the special tool that craftsmen use to assemble the steel skeleton. You also need to know something about how the drywall is assembled with the other walls, as well as the ceiling and floor where the wall is to be erected.
Then you avoid the wall suddenly falling over or being pushed over. At the same time, you also need to know something about how to properly insulate fry reglet, so that the sound and fire insulation is most optimal. If you want to be absolutely sure that the wall is in order, then it is a good idea to hire a craftsman for the job. This also gives you someone to complain about if you are not satisfied with the work. You would not have had it if you had done it yourself.
Then you should either live with the faults and defects that the wall had received or hold a craftsman anyway. Craftsmen run with free pricing. That is, there are no fixed price agreements that dictate that it costs so and so much per. running meters, setting up fry reglet. So, to find the cheapest craftsman for setting up a drywall, you need to get some offers from several different ones.
