If your home's wood siding is having a problem with mold and mildew growth, then you need to actively take steps to prevent it. While it is simple to clean the existing stains off of your home using an oxygenated bleach solution and a natural-bristle brush, the real task lies in preventing future growth from happening. The biological growth on your home's siding requires three things to be present:
- a food source
- airborne spores
Though you cannot control the presence of most airborne spores, you can take steps to remove the moisture and food source for the mold. Once these two things have been removed, then the mold will not be able to grow.
To remove moisture and the mold's food source from your home's siding, follow these time-tested tips:
Trim All Tree Branches Hanging Over Your Home
Mold and mildew use tree sap from overhanging trees and unsealed siding as their food source. You can prevent sap from dripping onto your siding by cutting back any tree branches that happen to overhang your home. Additionally, this will prevent you home from being in the shade where mold prefers to grow due to the absence of sunlight. If you have siding that has not been painted or properly sealed, consider doing so to prevent future biological growth.
Remove Landscaping Plants and Large Bushes Near Your Home
Mold and mildew will grow on your home behind large bushes or other landscaping plants that are in contact with its siding. To prevent this problem, walk around the foundation of your home and remove anything that is within a foot of your house. This barrier will allow your home to have some airflow around it and will prevent the shade biological agents like for their growth.
Re-Direct All of Your Lawn Sprinklers Away from Your Home's Siding and Foundation
Once you have removed the landscaping plants and large bushes that were in contact with your house, then it is important that you turn on your automatic sprinklers and watch where the water sprays. If you see water hitting your home's siding, then you need to re-direct the sprinkler heads so this no longer happens.
Add Water Diversion Pads Under Rain Gutter Downspouts
Since water that comes out of your home's downspouts and splashes onto your home provides the moisture that mold and mildew need to grow, you need to divert all downspout water away using splash trays. Splash trays are available in concrete and plastic options and when placed under your home's downspouts will divert stormwater away from its foundation and wood siding. You can purchase splash trays at your local home improvement or garden center.
Add Mildewcide to Exterior Paint in the Future
Finally, since your home has shown a proclivity to grow mold and mildew, it is important that you have mildewcide added to any exterior paint that is used to paint the house in the future. The mildewcide is odorless, colorless, and will not negatively affect your home's paint job in any way. Mildewcide added to the paint will simply prevent the future growth of mold or mildew on your home's wood siding.
