We did an outstanding job of repairing thermal insulation on a 15-storey building after a fire in one of the flats. Styrofoam on 2 floors was burnt under the layer of net, glue and plaster and the wall above the fire source was covered with soot, which was difficult to remove. An additional hindrance was the height and the fact that the building is located in the centre of Warsaw. We did the job perfectly well. There was no sign of the fire or any damages left. Such works at heights are undoubtedly our pride.
