Hi All,
Black patches of mold have been found near the wall edges and corners of internal ceilings. They do not appear to be localized in just one room or area, but are found in almost all parts of the house (kitchen, bathroom, bedrooms, family room, laundry). Whats puzzling is that we cannot identify what has been causing them. Some spots appear to have been painted over and then re-appeared. Some spots are nowhere near sources of condensation. There were some traces of previous leaks found on the ceiling but these were in the middle of the ceiling and far from the molds.
What could be causing these mold patches and how can this be fixed? Do these pose a serious safety issue? Any ideas on repair and remedial costs?
Thanks in advance for your inputs.
