How to Prevent Algae Mold and Mildew from growing on your house
Aside from hosing down your home, there are other ways to help prevent algae mold and mildew from forming on the side of your house.
- Tree limbs should not be pressed right up against the house, as this can cause stagnant air and deposit organic matter directly onto your siding.
- Prune all plants and bushes away from your siding, so there is ample air circulation in between them and the surface of the home.
- Avoid aiming your sprinkler system directly at your house, because moisture can increase your chance of mold and mildew growth.
- One way that many homeowners inadvertently import mildew to their home environment is in landscaping mulch. Mildew is a very common and natural growth on tree bark in the woods. When trees are harvested, the bark is converted to mulch, and the end result is that a new living organism has moved into your neighborhood, and wants to make a home for itself.
- Install gutters that will divert rain water away from your home.
- After a hard rain, make sure you wash off any wet dirt that may have splashed up on your house.
- Edge and trim your plants and bushes so that they don’t lay against the house. Mold and Algae grows best in dark damp congested places. The more open airflow you have, the better.
