Extension building in Widnau

After an extension build in 2008, smell pollution, damp and mildew arose in the bathroom and neighbouring areas. Over many years, a lot of experts came and went. At the end of February 2018, bauhelp! took over the consultancy mandate and, using modern and non-invasive methods in collaboration with the experts from aib tech GmbH, discovered the latent defect: one ventilation pipe had simply been cut during renovation and left without any connection directly behind an installation wall. As a result, damp and sewer gas arose. The defective ventilation of the sewage system furthermore led to a suctioning of the pipes, which entailed more smell pollution. After it was traced, an ad hoc renovation design was developed and implemented, so that the house was again habitable within a few weeks. The defects were documented in a way usable by the courts.
