Causes Of Stains and Discoloration on Vinyl Siding

When choosing a siding material for your home, there are many options at your disposal. From wood shakes and aluminum to wood clapboards and fiber cement, all have their pros and cons. However, vinyl has long been the most practical and popular siding material choice among homeowners looking for the best value. One of vinyl’s drawbacks is that it is susceptible to ugly stains and discolorations. 

Homecraft® Inc., proud provider of premium vinyl siding from top manufacturers Mastic® and Provia®, explains below the top causes of stains and discolorations on vinyl siding, as well as what you can do to remedy them:

Mold and Mildew

Mold and mildew growth result in greenish black stains on vinyl siding, leaving it unsightly and ruining your home’s curb appeal. This growth usually occurs as a result of water infiltration, so you’ll want to make sure your roof and gutters are in tiptop shape at all times. 

Algae 

Algae is often confused with mold, but this type of staining and discoloration can be found on siding that is shaded and always damp. While these stains are principally a cosmetic concern and can be cleaned by scrubbing with mild soaps, or more aggressive cleaners, there may remain a hidden problem in the form of widespread rot or insect damage. 

Dealing with Mold or Algae on Siding

Where there are apparent “growths” on your siding, consider the following measures:

• Clean siding properly with soap and water, or stronger cleaners if necessary
• Make sure siding is allowed to dry properly and completely 
• Increase mold/algae resistance by using a fungicidal additive in your paint or stain
