Strong and affordable, vinyl siding appears on numerous homes throughout the country. Unfortunately, it’s prone to mold. That’s why houses with vinyl siding often need more frequent power washing than other homes. Learn more about this issue and how to prevent it below. 

Why Does Mold Grow on Vinyl Siding?

Mold thrives in dark, moist places. That’s why it often forms on outdoor surfaces, including vinyl siding. When the siding is shaded by trees, shrubs, sheds, porch roofs, or other obstructions, mold will be drawn to the darkness.

Similarly, mold enjoys the moisture caused by water-related issues like overflowing or leaky gutters and sprinklers that spray too close to your siding. Finally, because mold feeds on dirt, you’ll often find it on siding that hasn’t been cleaned in a while. 

Mold usually resembles a rough, fuzzy, or velvety stain and can appear in various colors, including green, black, yellow, white, and blue. It may discolor your siding, attract pests, or, in the case of black mold, cause water damage by holding moisture to your siding. Moreover, if the mold enters your home, it can cause health problems like coughing, sore throats, burning eyes, skin rashes, and asthmatic or allergic reactions. 

How Can You Prevent It? 

Remove any obstructions from your siding to ensure it receives adequate sunlight, which will discourage mold growth. In addition, regularly inspect your gutters to prevent overflowing or leaks. Grab a ladder, some gloves, and a gutter scoop or trowel, and remove any twigs, leaves, or other debris.

Then, flush your gutters with a garden hose to ensure there aren’t any holes. Next, make sure none of your sprinkler heads spray directly onto your siding. You should also keep your siding free of dirt that mold could feed on. The best way to do this is to schedule professional power washing once a year.

While it’s possible to power wash your own home, you may damage your siding by applying too much pressure. In addition, you won’t have access to professional tools, such as high-quality power washers, high-pressure and low-pressure hoses, and various nozzles with different sizes and angles to accommodate different parts of your home.

How Can You Remove It?

If mold already exists on your siding, professional power washing can remove it. If any stains linger afterward, apply a solution of 70% water and 30% white vinegar with a soft cloth or soft-bristled brush. Scrub from the bottom upwards to reduce the risk of streaks.
