Q: I have an older concrete block home and on some walls inside the house, I often find condensation building up on exterior walls. I want to find the source of the moisture and I canât seem to locate it. Moisture is not running down the walls onto the floor and there are no plants next to the wall outside that are being irrigated. What do I do next to find the problem?
A:Â Get several large pieces of kitchen-style plastic wrap and duct tape them to the walls in a few locations where this moisture problem seems to be happening. See if you find moisture on just one wall or more walls. Once you find out the location of your problem, you will have to concentrate your investigation on that area of the house. You may need to do what they call âout-sulationâ to prevent moisture from getting through the problem walls.
