Mold on the Outside of Your Home

9/25/2018 (Permalink)

When you think of places where mold may grow, what is the first thing that comes to your mind? Perhaps a damp, dark basement or crawlspace?  While this may be one of the most common places, your home's exterior siding may also be susceptible to mold growth.  

Causes of Mold on Siding

Excessive humidity and moisture can create an attractive environment for mold growth on several kinds of siding, including low-maintenance vinyl.  Siding is designed to allow rainwater and other types of moisture to run off the exterior of your home, but sometimes otherwise durable siding can have mold growth under certain conditions.  Since some moldy types may need humidity to grow, warm and humid weather conditions can cause a mold outbreak on your siding.  

Mold likes darkness which can also play a role.  This means that the shady sides of your house maybe at risk.  These areas will tend to be the slowest to dry out after heavy rains so moisture levels will remain higher.  

Vinyl Siding Mold Removal and Prevention

First, keep your siding clean of dirt and grime. You can use a simple garden hose or pressure washer to do this.  

Second, try to target the trees and shrubs that are located around your house.   Check to make sure they do not have any contact with your siding.  Regularly trim your trees and shrubs to minimize shaded areas that can encourage mold growth.  

Finally, take steps to reduce the amount of moisture that comes into contact with your siding.  If you regularly water your lawn, be sure to adjust sprinklers so the water does not hit your house.  Check gutters in the spring and fall and make sure they are clean and in working order.  Clogged gutters can cause the rainwater to run down the side of the home and this can increase the moisture level.
