Many newer homes are now being sided with artificial stucco siding, or EIFS (Exterior Insulation Finishing Systems). This is essentially polystyrene foam with a base coat, reinforcement mesh, then another base coat and then a finishing coat of stucco over the top. This is a terrific product, as it adds insulation value to the home, not to mention classy looks. However, it can also be a serious and very expensive repair if it isn't installed correctly and/or water gets behind it.
There are several manufacturers of artificial stucco, and many builders installing it. Having it inspected allows you to know if there is a problem, and even if there isn't, you will be aware of the areas you need to keep caulked, and what to look for in case of trouble.
