Experts addressing frozen interior walls say the appropriate response begins with a proper assessment of the building. Traditional inspections are carried out in autumn and spring to identify problem areas in the housing stock. Residents' complaints and requests are also taken into account when repair work is scheduled. Where the inspection or resident reports point to gaps, the recommended method is to seal the joints during repairs. This approach targets places where cold air and moisture can enter the wall structure rather than treating every affected surface in the same way. The guidance makes clear that sealing should follow diagnosis, not precede it. The report does not set out a single universal solution for every type of wall or foundation.
