Composite Deck Cleaning Third Lake, IL

Composite deck cleaning for Third Lake homes

Composite deck cleaning in Third Lake starts with knowing the housing: a small lakeside village near Grayslake. We see a lot of older cottages and newer lake homes, and the work is planned around it.

Third Lake sits on Third 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 Third Lake

1. Identify the productCapped, uncapped or PVC, and which brand. It decides the cleaner and the pressure.
2. Clear and protectFurniture, rugs and planters come off. Rugs left on composite are the most common cause of shadow marks.
3. Apply cleanerA composite-safe cleaner with a sodium percarbonate base, or an oxalic-based one for tannin and rust stains.
4. Agitate and rinseSoft brush on problem spots, then a low-pressure fan rinse under 1,500 PSI, wand kept well off the surface.
