Exterior Insulated Finish System or EIFS, commonly known by the trademark “Dryvit”, has become popular exterior skin for both residential and light commercial structures for about the last 15 to 20 years. It is frequently, and incorrectly, referred to as “stucco”.
Like all surfaces it must be treated with care. We will effectively clean your EIFS home or building by applying a mild cleaning solution to kill any green algae, and/or black or gray mold and mildew. This solution will also soften the bond of dirt and pollution to the surface. A low to medium pressure rinse of fresh water will finish off the cleaning. If needed a second application will be employed.
Some common issues we have seen over our 22+ years is that EIFS can be prone to permanent staining due to rust, chimney soot, rain splattering dirt up to about 2 to 3 feet above the ground level. Also, if the EIFS hasn’t been maintained properly, even normal algae and dirt can become deeply embedded into this very porous surface. Rest assured, we at Renorr Dynamics have the experience and skills to get it as clean as is possible, and with the lowest possible pressure.
