Composite Deck Cleaning Vernon Hills, IL

Composite deck cleaning for Vernon Hills homes

Most of our composite deck cleaning calls in Vernon Hills come from homes with 1980s-to-2000s subdivisions with HOA neighborhoods. That means original builder decks reaching 20 to 30 years, which changes the prep more than the stain.

Vernon Hills sits on Big Bear Lake and Little Bear Lake, and waterfront wood weathers faster on the water-facing side than the house side. We check both and often give the exposed side a second coat.

Composite decks are the ones that get damaged most often by general pressure washing, because the surface looks tough. It is not. Capped composite has a thin outer layer and a narrow-tip wand will strip it in stripes. We use a soft-wash approach: cleaner, dwell, gentle agitation, low-pressure rinse. If your composite deck has black spots that will not come off with a hose, that is mildew in the surface and it needs the right cleaner, not more pressure.

How the job goes in Vernon Hills
