The National Association of Home Builders warns that synthetic stucco, (also known as EIFS) even when it's properly installed, can develop wood rot-causing moisture intrusion problems. The building materials manufacturer, USG, which is a major manufacturer of synthetic stucco in earlier years--has put together a Web site warning homeowners about the dangers of this synthetic stucco which was widely used in the 1980s and 90s around the US.
The entire problem with synthetic stucco or EIFS (for Exterior Insulation and Finish Systems) relates to how it's applied to a home. First, rigid insulation board is glued firmly to the home's frame or sheathing with an adhesive. Next this insulating board is covered with fiberglass mesh and two layers of the hard synthetic finish. This synthetic finish layer resists water, which one would think would be a good thing. Unfortunately, when/if water gets behind the synthetic stucco, it remains there and that's how the wood rot begins. The basic problem is, the EIFS systems lack a harmless path of escape for water. The reality being, water always seems to find its way behind siding.
The National Association of Home Builders urges homeowners to have their homes checked at least yearly by a professional experienced in EIFS water intrusion inspections. The NAHB further urges homeowners to immediately take action on any needed repairs. Delays can cause minor problems to escalate into major nightmares that can cost tens of thousands of dollars to remedy.
Like others who have researched the EIFS problem, NAHB suggests that many homeowners have their house re-sided with something else. In our opinion, HardiePlank is the best option available. It now comes with a 30 year warranty.
