Cleaning stucco that has turned green, most people don’t think that stucco can come back to the original colour. Exterior stucco walls are usually made of cement plaster, which makes the material both weather-resistant and very porous. This porosity results in the fast absorption of stains. The most common stains on exterior stucco are dirt and mildew. Both can be effectively removed using the proper tools and procedure. Nationwide Stucco cleaning service will help your building looking like new. Our Stucco cleaning service maintenance program can be performed once or twice per year.
