Stucco System Types in Irvine
Traditional three-coat stucco (scratch coat, brown coat, finish coat over metal lath): the original system used on homes through the 1980s. Most durable when properly installed and maintained; typical lifespan 30–50+ years with maintenance. EIFS (Exterior Insulation and Finish System, "synthetic stucco"): foam board + base coat + fiberglass mesh + finish coat. Lighter weight, better insulation value, but moisture-sensitive at joints and penetrations — homes from the 1990s–2000s with EIFS have had significant moisture problems from improper installation and maintenance. One-coat stucco: a single thick coat with fiber reinforcement over building paper — faster to install but some durability questions over 30+ years.
