The guys clearly understand what they are doing, but they are messing around (apparently thinking that they have already created a "name" for themselves). The bottom line is simple: they were poorly insulated - you need to "go" to the next balcony when warming, so that the side.the wall that was "not sewn up" did not freeze and did not get wet. They didn't do this to me, the wall was damp, the fungus started. They refused to redo (correct this part), or for money. I post the photos as they were done and as it was necessary. I will also leave a review about them in the FB so that they do not get caught in a divorce or a bad job. All good specialists!
