Stucco Damage In New Homes
Stucco damage in new houses is nothing new. Sadly enough, home building has not resolved this problem despite decades of failure and costly repairs.. So what causes damage in stucco homes? Well, the name itself is usually misleading or wrong. There is almost never any damage to the stucco. The damage is almost always to the structure, drywall or insulation but not the stucco. The problem is not even that water gets behind the stucco. That is actually expected. The problem is that when the water gets behind the stucco, it either does NOT have the ability to get to the ground. In other words, it is trapped between the stucco and the structure. This allows the water to degrade everything it touches.
The other problem with water getting behind the stucco is that the house is not waterproofed correctly. The house should be sealed and is considered an "envelope" that should keep water out EVEN IF THERE WAS NO OUTSIDE COVER OF STUCCO, BRICK, WOOD OR ANYTHING ELSE!
So how can you know you have water damage behind the stucco? Great question. Water damage can take a really long time - as in 8-10 years or more, before it is visible outside. You can check for unusual water or moisture with a moisture meter and you probably should check occasionally if you have a stucco house.
