FAQ: Maintenance and Warranties

What types of warranties are available with EIFS?

A variety of warranties are available, depending on the system installed and per the manufacturer's requirements. Samples of the warranties are available on request from the EIFS manufacturer.

What type of maintenance is required for EIFS?

Unlike wood, stucco and other siding materials, EIFS rarely need painting. Most EIFS systems are specifically formulated with 100% acrylic binder, which gives EIFS superior resistance to fading, chalking and yellowing. As a result, the systems tend to maintain their original appearance over time.

Periodic maintenance should include thorough checking of the flashing and sealing to ensure that the building envelope remains watertight. Damaged or missing flashing should be repaired or replaced immediately; likewise, cracked or deteriorated sealants should immediately be repaired, or removed and replaced.

How can you clean the finish coat?

EIFS manufacturers provide procedures for cleaning specific systems. Periodically, EIFS finishes may need to be cleaned to remove dirt, algae (usually green stains on the surface of the finish), or mildew (generally black stains that look like dirt) that can accumulate on the surface. Basically, mild cleaning detergents, and low water pressure cool water, and a soft bristle brush. DO NOT USE THE FOLLOWING: cleaner that is solvent based; high water pressure; hot water; or wire brushes.

What materials can I use to recoat my EIFS?

For situations where you might wish to change the color of the building, or paint the building for some other reason, EIFS manufacturers produce several quality paint products (acrylic or elastomeric) to recoat and enhance the existing coating. Other alternatives are to use a quality, high-grade 100% acrylic exterior grade paint. Before recoating, appropriate repairs should be made and the surface should be cleaned to remove any surface contamination.

Whom do I contact if I need repairs?

EIFS manufacturers provide a "distributor locator" on their website to locate the distributor nearest you. The distributor can assist you in locating appropriate qualified contractors. The Association of Wall and Ceiling Industry (AWCI) also provides on its website a national database of contractors who have gone through and passed the "EIFS Doing it Right" course.

How long should EIFS last?

If properly maintained, the cladding will last the life of the building. Initial EIFS walls were installed in the late 1960’s and most are still in service as of this writing (2014).

Do insurance companies cover EIFS projects?

The EIFS Industry Members Association (EIMA) compiled a list of insurance access points that offer coverage to EIFS projects. In addition, EIMA is working with some other companies that do not currently offer insurance for EIFS projects, on expanding their coverage to be more inclusive for these projects.
