EIFS (Synthetic Stucco)

What is EIFS?

Exterior Insulation and Finish System, or EIFS, is also known as Synthetic Stucco. EIFS provides insulation, weatherproofing, and a finished surface in a single integrated product. It is also often called Dryvit after one of the largest manufacturers of this type of system, although there are many companies who make EIFS.

Potential problems with EIFS

Since the first moisture damage problems were discovered in 1994, the “EIFS problem” has been a source of some anxiety for prospective homebuyers. Research has determined that wind-driven rain enters the waterproof barrier EIFS surface in and around windows and other penetrations and at wall/roof intersections. Because barrier EIFS systems provide no means for allowing water to escape the wall cavity, intruding water is trapped inside the system, where it can remain for extended periods of time and eventually damage and even rot wood framing, sheathing and other moisture sensitive building components. These problems can occur regardless of the age of the building or the quality of construction, therefore EIFS homes should be regularly inspected.

What can we do for you?

An EIFS inspection is intended to identify areas of high moisture content in the sheathing and framing. The inspection can take several hours, and may even span more than one day. We offer you the services of qualified, specially-trained EIFS inspectors who will look for evidence of damage and test for moisture.

The following three-step process is used in conducting the inspection:

1. A visual inspection of the exterior to document installation details, areas of visible damage, and status of repairs.
2. Use of a Wet Wall Detector to perform a limited moisture scan of the EIFS in suspect areas.
3. An interior infrared scan for moisture intrusion in the exterior wall cavities in those areas exhibiting damage to the EIFS from the exterior.

The evaluation is non-destructive and non-intrusive and based on visibility and accessibility of the interior and exterior. Probe testing is not done as part of the inspection as this can, in most instances, damage the exterior envelope and make it susceptible to future water intrusion. The results of our findings are presented in an easy-to-understand comprehensive EIFS inspection report complete with digital photographs that highlight the condition of the EIFS.

EIFS inspections cannot be done during wet weather. It is therefore advisable to allow sufficient time in the real estate sales contract for the testing of houses with EIFS exteriors.
