Condensation issues, if detected early, can be treated easily without future defects. It can be treated by installing extractor fans in the humidity areas so that the moisture air gets expelled out. Avoid the use of moisture-producing portable gas heaters to warm the cold and the damp rooms. Extreme condensation may result in chipping or bubbling of paints on the walls. It can be treated by removal of paint, cleaning the surface, and repainting it. Repair of bubbling defects in interior plaster is a similar procedure.
