Stucco moisture problems
If your home is in a climate where the rainfall is moderate or higher, then there is his of having issues with your wall assembly. A lot of the problems with stucco have to do with improper draining, and rain water that doesn’t dry. Due to it’s porous nature, rain water that normally runs off a wall will get absorbed by the stucco. Additionally , windows tend to shed moisture into walls, this is especially true at the bottom of the window. When improperly drained or not quickly removed, the water will damage the materials in the structure and it can lead to rot and mold issues. There have been major advancements in insulating homes over the last thirty years and have positively impacted the ability of a home to save energy whilst slashing cost of air conditioning and heating bills. The negative to this however is that the wall cant dry as effectively as it did when homes weren’t so tightly built. Older houses that weren’t well insulated could simply dry out their walls on their own. During a hot summer if the wall got wet the suns rays would dry it from the outside all the way in. During the winter months, the heat generated by boilers can dry out walls from the inside out.
The manner in which your home was built can also have an effect.
As we move towards homes that are more sealed and insulated, the wall has foregone it’s drying potential and new ways are needed to get the wall to drain and dry. Before, the insulation would allow for the passage of air through walls and this would help with the drying of any trapped moisture. With the modern insulation craze of closed cell foam, this passage of air can’t happen and thus the water will remain stuck.
The construction world took time to realize that this is a problem, however now people are adapting. It can take up to eight years for these issues to begin revealing themselves. At the same time sometimes it can take as little as two years. There are codes now that will try to rectify the problem that arise from wall systems in which the wetting and drying potentials aren’t balanced, and products are out there that can take the moisture overload.
