Green and brown discoloration on siding is typically caused by the growth of algae, moss, or mildew, especially in areas with high humidity, moisture, and shade. This is a common problem for homeowners in Saratoga, Albany and Schenectady County, NY, due to the region’s climate and environmental conditions.
The growth of algae, moss, or mildew on your siding can be exacerbated by a lack of sunlight, poor ventilation, and moisture buildup. If your siding is not regularly cleaned or maintained, it can become an ideal breeding ground for these types of organisms.
To prevent or remove green and brown discoloration on your siding, you can try the following:
Regular cleaning: Regularly clean your siding to remove dirt, dust, and other debris that can promote the growth of algae, moss, or mildew.
Proper ventilation: Ensure proper ventilation of your home and siding to reduce moisture buildup, which can contribute to the growth of these organisms.
Trim trees and bushes: Trim any trees or bushes near your home to reduce shade and improve sunlight exposure to your siding.
Pressure washing: Pressure washing your siding can help remove stubborn stains and discoloration caused by algae, moss, or mildew.
