About Jim Locksley

One day when I was walking around my college campus, I saw a group of people with these yellow tripods. At first I thought they might be photographers, but they sure looked like strange ones! I went up and asked them what they were doing, and it turns out they were a group of students from a construction class who were surveying the land for a project. I was fascinated. I was able to sign up for the class the next semester, and while it didn't stick or change my professional trajectory, it did create a new hobby for me! Ever since then, I've been interested in construction, from surveying to management to the actual building. I figured running a blog about it would give me a nice excuse to keep up my interests!

What Does It Mean If There Are Black Spots On Your Siding?

by Mike Brewer

Black spots on your siding can negatively impact the appearance of your home, thus detracting from your property value. Knowing what causes black spots to appear on your siding and how you can get rid of them can help you take care of your house.

What does it mean if there are black spots growing on your siding?

The black spots you're seeing on your vinyl siding is very likely mold or mildew. Both may grow on vinyl siding in the right environment.

What causes mold to grow on siding?

Mold and mildew frequently grows in conditions that are warm, humid, and protected from sunlight. Parts of the house that are blocked from the sun or are repeatedly exposed to moisture can easily develop a mold or mildew problem.

What can you do to remove mold growing on your siding?

The best way to remove mold is to use a solution of bleach mixed with water. While chlorine bleach is especially good for removing mold and mildew, chlorine bleach is toxic for plants and can damage your landscaping. To avoid problems, try using oxygenated bleach. Oxygenated bleach is strong enough to kill mold and mildew but will not harm plants. Use a bucket of warm water mixed with bleach, then dip a scrub brush into the solution and scrub down your siding.

When the black spots have been removed, rinse the siding with a strong jet of water from a hose. If you must use chlorine bleach for this project, soak your landscaping in water, then cover your landscaping with a tarp while working in the area.

What can you do to prevent the return of mold in the future?

You can prevent mold from growing on your siding by exposing the vinyl siding to sunlight and fresh, dry air. Below are a few tips that can help you with this:

  • Move landscaping. Landscaping that grows against the side of your house can trap in moisture and prevent sunlight from reaching your siding, creating the conditions that are good for mold growth.
  • Prune overhanging trees. Overhanging branches can block the sun and drip rain water on the house.
  • Fix clogged gutters. Clogged gutters can cause rain water to run down the side of your house, also leading to mold growth.

Fixing these problems can help you prevent mold or mildew from growing on your home in the future. For more information about how you can protect your siding from mold, contact a skilled and reputable siding contractor in your area.
