Composite Deck Cleaning Zion, IL

Composite deck cleaning for Zion homes

Most of our composite deck cleaning calls in Zion come from homes with an older grid of homes plus newer subdivisions on the west side. In practice that means older decks and porches on the east side.

With Lake Michigan and Illinois Beach State Park close by, decks and fences here hold moisture longer in the mornings. We schedule the wash early in the week so there is time to dry before stain goes on.

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 Zion
