For homes with white or cream-colored siding, algae is easy to spot, as its green color highlights the stain and discoloration on the vinyl. Fortunately, algae is a common form of bacteria growth found on vinyl siding in Springfield, IL, and can be easily treated by our experts at Petersburg Power Washing, Inc.. Algae grow in shaded areas that do not have access to direct sunlight. North-facing slopes are typically where you will find algae growth. Humidity and water are what algae require to survive. If you notice green stains on your vinyl siding, give us a call, and we’ll provide safe and long-lasting power washing solutions to restore your home’s exterior surface.

Mold & Mildew

Living in Springfield, IL, your home is guaranteed to experience a range of temperatures and weather conditions. During the summer, humidity causes moisture and dirt particles to build on your vinyl siding. If areas of your home are not facing the sun or are more susceptible to lasting moisture, these conditions are perfect for mold and mildew to grow. The key differences in identifying the two fungi are their texture and color. Mildew is often powdery or fluffy looking and usually grows in gray, white, or yellow shades. While mold looks slimy and can be colored anything from dark green to bright red and black, depending on how long it is left to grow. At Petersburg Power Washing, Inc., we take the health of your home and family seriously. So when you spot mold or mildew growing on your siding, give us a call right away for a deep power washing service.
