The life of an EIF System depends on how well it was installed initially and how well it has been maintained. An example of the required maintenance includes repairing caulking, which eventually wears out and must be replaced. Some older EIFS projects that are still in good shape today go back to the 50s in Europe and the late 60s in the North America. Other than needing a paint job to freshen them up, these installations are in good shape. With proper preventative maintenance, life span can be easily extended to over 50 years.
