Stucco has been the premier siding in Arizona since the 1980s and it looks like it will continue to be for the foreseeable future. Yet it's not without its problems. Often, builders do not allow stucco to cure or hydrate long enough after it's applied before they paint it--and that can result in peeling and flaking within a few years. Poor flashing around windows, doors and other wall penetrations can result in leaks. Weep holes in the J-metal at the bottom of stucco walls can get plugged and allow rainwater to accumulate inside the walls. And if someone applies stucco all the way to the ground, they can create conditions conducive to termite infestation. Finally, if you apply a non-breathable coating over the top of stucco, moisture won't be able to evaporate. Luckily, you can avoid all of these problems with stucco if you work with experienced professionals. When you need a stucco contractor at your home, be sure you are working with a Rosie on the House-certified stucco partner.

All masonry walls, including concrete-based stucco, are prone to efflorescence when they get wet. The powdery discoloration occurs when the wet walls dry out, pulling the salt and lime that is part of the stucco to the surface of your home’s exterior walls.
