Synthetic stucco also called Exterior Insulated Finish System (EIFS) has positive attributes:
- Less expensive than conventional stucco
- Fairly easy and fast to install
- Can provide a very attractive appearance to the exterior of the home
- Economically provides the appearance of expensive masonry details
Unfortunately, EIFS can be problematic:
- Moisture and water intrusion can create mold and wood rot inside the walls, EIFS tends ot hold onto moisture.
- The wood rot can ultimately create structural issues.
- It’s very important to seal all penetrations (electrical outlets, dryer vents, window frames, door frames)
- Poor workmanship is very common. The material must be installed exactly as recommended by the manufacturer. Even then it can be problematic.
- There have been class-action lawsuits associated with EIFS
As a result of the concern, most inspectors will recommend further evaluation of the EIFS by a specialist. EIFS inspections are performed by specifically trained inspectors with specialized tools. EIFS inspections can be time-consuming and invasive.
Usually, the presence of EIFS doesn’t develop into a serious issue, but sometimes it does.
