Mold on the exterior of your home is usually in the form of green moss. Since moss is a form of mold it can "deteriorate or eat up the outside of the home" according to Kevin Bristol President of Advance Mold Remediation. Mold can also make your house look dirty and old and wreak havoc on your paint job. This article will tell you how to get rid of mold on the exterior of your home and how to prevent its re-growth.


Mold is a dangerous thing to leave growing on or in your home. Not only is it dangerous for the structure of your home but also for your health. The health conditions that can result from being exposed to mold are headaches, asthma, allergies and more. "Green moss or [mold] can cause allergic reactions when touched, but not very many people have allergies to moss." states Bristol.




Bristol advises you to "buy a vinyl cleaner if you have vinyl siding or aluminum siding" to keep your home free of mold growth if you live in a mobile home. If your home is stucco or wood you also need to clean your home but may need to use a high power water sprayer. "Power washing companies will do it for as little as $100" states Bristol. "The exterior of your home should be cleaned at least once a year including the gutters if they constantly have water in them" advises Bristol. Bleach mixed with water can be used to spray on spots where mold is growing. You may need to use a scrub brush. Remember to wear gloves and face mask.

Mold can also grow on your roof which can damage the shingles. If you have trees hanging over onto the roof cut and trim them back. The leaves can hold a lot of moisture and this can cause mold and mildew. Spray the roof with a liquid bleach and water solution paying special attention to the rain gutters.

A wood deck or fence railing may have problems with mold growth. To prevent mold growth, scrub and clean the mold away and allow the surface to dry. Trim back trees and vegetation to keep the area dry and allow sunlight in. Paint the wood with a sealant to prevent further mold.

Mold will usually grow where there is excessive moisture on your home. Check the direction of the sprinkler spray and see if too much water is pooling around the base of your home. If you have a lot of shade trees and you live in a humid climate you will not get much sun to dry out and kill the mold. Consider trimming the trees to allow some sunlight on your home. Mold can grow if there is a lot of damp or excessive plant growth right up next to the house. If you space the plants out around the foundation to allow air flow to dry out the soil this will prevent mold. If the mold is really bad you can spray the area with a fungicide but this could kill your plants and be toxic to pets so be cautious and read the label.

Once you have cleaned up the mold you may consider repainting your house with a mildew-resistant paint.
