How To Clean Mold And Mildew Off Vinyl Siding

How To Remove Mold From Vinyl Siding

Housecleaning Tips : Removing Mildew From Vinyl Siding

Q: My house is 25 years old. Its covered with vinyl siding. Every summer, mold and mildew develop on the north side of my house. Every few years I remove it. Is there some coating I can apply to the siding to stop the mold and mildew from reappearing? Its aggravating. What about some sort of paint? Im open to any and all ideas. Robert C., Sylvania, Ohio

A: I have the same exact issue at my own home, although its siding is fiber cement. You may have black mold and mildew or green algae growing on the north side of your home if you live north of the equator. The north exposure provides the perfect conditions for this organic growth.

Heres the bad news: Theres no magic paint or coating Im aware of that will keep your siding free of mildew, mold and algae. These three living organisms are just about everywhere. They just need two things to grow: water and food. The northern exposure of houses provides ample amounts of water.

Because direct sunlight doesn’t wash north-facing walls, water there is often slower to evaporate. Morning dew can and does form on all the surfaces of the house when the surface temperature drops below the dew point of the air.

Dust and other pollutants can also be food for some of these organisms. Realize that food is everywhere, even though its invisible. Old oil-based paints were made from alkyd oil resins. These oils are scrumptious food for mildew and mold.
