(Exterior Insulation and Finish System)
One of the most common issues with EIFS is bird nesting.
If untreated, bird nesting can cause damage to your stucco house as it can create an environment for mold to grow where there is no waterproof system in place.
Without maintenance; wood framing, insulation, and sheet rock can be tarnished easily. Aside from the damage to your property, black mold can also cause illnesses.
