Siding protects the structural integrity of your home and safeguards it from the weather 24/7. One of the most common problems with home siding is unhealthy mold growth. Wood is particularly susceptible to mold buildup and rot, and vinyl can easily become moldy as well.
Mold can harm your health and damage your home, so it’s vital that you spot it and deal with it if it shows up on your siding. It’s even better to prevent mold growth! Here’s how:
Pesky fungi build-up like mold grows without being seen at first. In fact, you may smell it when you are outdoors before you see it.
When your siding begins to get moldy, you will see nasty looking patches on your exterior. It appears fuzzy, slimy, and can vary in color from dark green to bright red or black. If left untreated, mold can cause structural damage to your home. It’s unhealthy and can spark allergic reactions as well as provoke respiratory problems like asthma.
Anyplace excessive moisture and a lack of sunlight exist together, unhealthy mold can grow and thrive. There are some basic things that contribute to mold growth on your siding, and the good news is—they are avoidable!
Mold on your siding thrives when the ground adjacent to your home is constantly wet. Poor drainage, a faulty gutter system, and leaky faucets can all contribute to water pooling around your foundation—which mold loves.
Shade created by the trees in your yard keeps the sun from accessing your siding, hindering its ability to dry off after it rains or snows. In humid, damp climates—like Dayton’s—mold can thrive as a result.
Note: Pay special attention to the north side of your home exterior because that is usually where the most mold or mildew builds up. The reason for this is because the north side gets the least amount of direct sun, making it an ideal place for mold to grow. When moisture doesn’t have the opportunity to evaporate, it just sits on your siding, giving mold the perfect conditions to thrive in.
Rather than dealing with trying to eliminate unhealthy mold, take these simple steps to avoid it in the first place.
One way to permanently rid your siding of pesky mold is to reside your home with Hardie siding. Made of cement, sand and cellulose, this durable siding resists moisture intrusion and mold growth.
If you spot mold on your siding, understand that the quicker you deal with it, the less mold you will have to remove. If mold appears, handle the issue by using a natural anti-fungal soap or a treatment recommended by the manufacturer. Test anything you use on your siding in a small area to verify it will work effectively and won’t cause any damage.
Create your own cleaning solution by mixing three parts vinegar with seven parts water. Scrub the moldy area with a cleaning solution and let it soak for five minutes before rinsing it thoroughly. If one round of cleaning doesn’t remove all the mold, clean it again until the mold is completely gone.
