I wonder if this should be inspected or just painted/spackled over? We have developed cracked joints in interior walls in practically every room in the house over the past 4 months, including the upper floor paneling. Sometimes the cracks are up to 2 mm wide.
The facade and the lecablock base show no signs of cracks, and the floor does not seem tilted except in a few isolated spots in certain rooms (only tested with balls and a short level, though).
The house is from '62, wood frame with an exterior brick facade on the ground floor, slab on grade on clay soil. The interior walls are probably plywood.
We've only lived here since August and have installed mechanical ventilation. So, it's been very dry inside during the winter, which makes me wonder if that might have caused the cracks... Leaning towards settling but curious about what you think.
