What Causes Algae To Grow On Your Home's Siding?

Posted on

Algae is green and slimy, and when it grows on a home's siding, it can be very unattractive. As a homeowner, finding effective ways to remove the algae from your home's siding can help you care for your property and keep your house looking its best. The following FAQ will help you care for your siding and remove algae when it begins to grow.

What causes algae to grow on your home's siding?

Algae grows on siding when the conditions for growth are right for growth and when food is available. Algae likes to grow in areas that are moist, warm, and regularly exposed to sunlight.

What can you do to remove algae from your home's siding?

To remove algae from your home's siding, you'll need a garden hose, oxygen bleach, a bucket of warm water and a long-handled scrub brush. To remove the algae from your home's siding, mix the warm water and the oxygen bleach together in the bucket. Dip the head of the scrub brush into the bleach and water solution, then use the scrub brush to scrub the algae off the side of the house. When you're done, use a strong jet of water from the hose to rinse the siding.

If you don't have oxygen bleach on hand for this task, you may also choose to use chlorine bleach. Chlorine bleach is an acceptable cleaner to use on your home's siding, but may kill plants in your landscaping. If you choose to use chlorine bleach to clean the algae from your home, water all the plants in your landscaping, then cover the plants along the perimeter of your home with a protective tarp. This will prevent the bleach from doing damage to your plants.

If your siding is prone to developing algae, what can you do to prevent the algae from returning?

The best way to prevent the algae from returning is to change the conditions that make algae growth possible, and remove the algae's food source. Algae likes water, so to keep your home dry, point all sprinklers away from your home when watering your lawn. You may also consider cutting away any shrubs that grow against the side of your house, as branches and leaves can hold in moisture. Algae also needs food to grow. Fertilizers and organic materials like dirt can all be a food source for algae, so keep your home's siding clean, and avoid spraying fertilizers near your home's siding.

For more information about caring for your home's siding, removing algae from the siding and protecting your siding from damage, contact a siding contractor in your area. Siding contractors can discuss the care and maintenance of your home's siding, and can also give you pointers and tips that will help you keep your algae in good condition.
