The second to last reason for what causes mold in a condo is through the building’s exterior. Another way water seeps through is pointing, or the concrete mortar that is frequently seen around bricks and windows in older buildings. Via weakened building components, rainwater may enter laterally and become trapped in the outside walls. As mold issues start to develop, it usually means that there is a lot more on the other side of the wall by the time you see something on your condominium wall.

The last common reason is flat roofs, which can frequently lead to problems. The flat roofs of many condominium complexes are susceptible to damage and sagging. Also, if they are not properly engineered, they won’t shed water as they ought to. Water then enters the flats below through the roof.
