Mold on walls

April 15, 2015


If you see mold at the bottom of an interior wall, you have a problem.  Many times this has to do with flaws in design or construction, and sometimes it can be attributed to poor application procedures of paint.  This photograph is a good example of the former, ie: design flaw.


The top edge of the foundation wall is not sloped properly, therefore, water cannot run off freely. Because it is level (and in some cases back sloping), the water can accumulate before running off. The space left between the wall plywood panels and the top edge of the concrete foundation wall is not large enough to prevent back splashing onto the bottom edge of the plywood panels. In addition to this, the edges of the plywood panels did not receive any kind of coating to prevent moisture penetration.


Checking of the bottom part of the panels was in evidence within six months. Within eight months, mildew growth presented an unsightly appearance all around this specific building.


If you see signs of moisture on an interior wall, or even if it has advanced to mold, call the experts at Grant Painting Group.  Take advantage of our experience!
