Professional EIFS & Dryvit Inspections and Moisture Testing Throughout Chicagoland

What Is EIFS?

EIFS is a multi-layer exterior wall cladding system designed to provide insulation, weather protection and a finished exterior appearance. Understanding how the system is constructed helps explain why moisture management, sealants, flashing and regular inspection are so important.

Where EIFS Problems Commonly Develop

EIFS moisture intrusion issues can develop in a variety of locations, especially where the system transitions, changes direction, or relies on sealants, flashing and penetrations to manage water. These are some of the areas we pay particularly close attention to during an EIFS or Dryvit inspection.

How We Inspect & Evaluate EIFS

Dunsing combines detailed visual evaluation with specialized EIFS moisture testing and targeted investigative methods. The appropriate approach depends on the type of EIFS system, the conditions observed, the location of the concern and the scope of the inspection.

Barrier EIFS vs. EIFS With Drainage

Older barrier or face-sealed EIFS systems relied heavily on the exterior finish, sealant joints and detailing to keep water from entering the wall assembly. Modern EIFS with drainage incorporate an air/water-resistive barrier and a drainage plane behind the insulation to collect and redirect incidental moisture that bypasses the exterior surface.

EIFS vs. Traditional Stucco

EIFS is sometimes referred to as “synthetic stucco,” but EIFS and traditional stucco are different exterior wall systems. EIFS typically incorporates exterior foam insulation covered by a reinforced base coat and finish, while traditional stucco is a cement-based cladding installed over a different wall assembly.

EIFS Requires Regular Maintenance

EIFS is not a maintenance-free exterior cladding. Sealant joints, flashing, penetrations, transitions and the finish surface should be periodically reviewed for deterioration or damage. Addressing small defects before water reaches the wall assembly can help extend the life of the system and reduce the potential for more extensive repairs.
