I have been specializing in repairing synthetic stucco longer than anyone else. Most companies that repair EIFS (Exterior Insulation and Finish System) have something else they do as a main gig. I have been focusing on repairing this product since 2000, and after the testing came out from the Oakridge National Laboratories in 2007 I doubled down on repairs. You would be hard pressed to find someone that has more experience repairing EIFS.
Over the years I have learned what works and what does not. Why, where and when this product fails. From my experience, it is not so much the product itself, but all the actors involved. From the manufacturer all the way down to the installer.
Many of the product’s problems are in the rearview mirror now, but it leaves a lot of projects needing repairs built before 2007. Not to say that there are no problems after 2007. You are always going to have incompetence. This is a product that pretty much everyone learned how to do the application on a residential project wrong, and then was supposed to change when the new advancements were made.
Unfortunately, most people don’t like change.
The version we have now in 2022 is a very good product, and does exceptionally well with moisture drainage. There is no reason every new EIFS project should not last the test of time. I guess the important thing is to have an applicator that is going to use the new version of the product and is educated in the latest techniques.
