Water damage drying in Kraków: from a wet stain to a dry wall

In the tenement houses of the centre and Kazimierz, damp can sit in the walls for a long time. Before anyone puts in a dehumidifier, the source has to be found: a leak in the plumbing, a leaking riser, water from the roof or condensation in a poorly ventilated room. The pro will measure the moisture in the walls, locate the leak and only then propose drying. Skip that and the stain comes back. A dehumidifier set up blindly only dries the surface while water keeps running inside the wall. So diagnosis comes first.

In Ruczaj and Bronowice new flats appear faster than the national average. Fresh plaster and screed keep giving off moisture for a long time, and airtight windows don't let it out. That's where the black spots in the corners come from in the first winter. With flats let to students and tourists there's insurance to think about: documenting the damage makes the conversation with the insurer easier later. Take photos and measurements before anything gets painted over.
