Composite Deck Cleaning Deerfield, IL

Composite deck cleaning for Deerfield homes

Most of our composite deck cleaning calls in Deerfield come from homes with North Shore neighborhoods with mature trees and shaded lots. That means decks that stay damp under old oaks and maples, which changes the prep more than the stain.

In southern Lake County, where Deerfield sits, the variable is shade. Sunny decks gray and dry out; shaded ones stay green. We treat each side of the same deck accordingly.

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.
