Longer than you or I. Great Grandpa Donnelly always said it should last the life of the building. I’ve found his words true if a house remains structurally sound. Stucco continues its hardening process with age. In fact, on some patch jobs, I’ve seen stucco holding the house together even though the framing has degraded. Think about this: stucco jobs more than 5,000 years old can still be seen today in the pyramids of Egypt! So why do people re-stucco? People re-stucco to freshen up or change the color or texture.
