Composite Deck Cleaning Gurnee, IL

Composite deck cleaning for Gurnee homes

Gurnee has large 1980s-to-2000s subdivisions with a lot of original decks, and that shapes how we approach composite deck cleaning here. We see a lot of builder-grade treated decks reaching 20 to 30 years old, and the work is planned around it.

The wooded corridor along the Des Plaines River means a lot of Gurnee yards are shaded for most of the day. Shaded wood stays damp, grows mildew on the north side and needs a thorough chemical clean and brightener before it will take stain evenly.

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.
