Vinyl Siding Algae Treatment

Vinyl siding is a very durable siding, and one of the most common. However, when it remains wet or is exposed to moisture on a regular basis, algae will grow on it. This is not only unsightly but can damage your siding over time. Removal and prevention are very important to maintain the efficiency of the vinyl siding.

Initial Cleaning

Clean your vinyl siding with a household cleaner and a scrub brush to remove the algae that is growing on it.

Stain Removal

After the algae is washed away, there may be green stain left on the siding. Spray the stains with bleach to remove them and kill any algae cells that remain.

Drying

The area where the algae was located needs to remain dry to prevent it from returning. You may have to move or repair gutters or trim tree branches to effectively dry the area.

Prevention Treatment

To seal the vinyl and keep algae from forming in the event that you can't keep the area dry, you will have to make it inhospitable to the algae. Spray the area with ArmorAll or another silicone spray to keep algae from forming.

Professional Treatment

Professionals can come to your home to remove the algae and place a treatment on the siding that will prevent regrowth, and even mold and mildew.
