Deck Cleaning & Power Washing in Atlanta

At least once a year. Georgia's humidity, pollen, and tree cover mean mold and mildew build up fast — especially on north-facing decks or decks under heavy tree canopy. If you're staining your deck, cleaning is mandatory as the first step. Some homeowners in heavily shaded areas benefit from cleaning twice a year.

We don't use traditional high-pressure power washing on composite decks. Composite manufacturers like Trex and TimberTech specify low-pressure cleaning (under 3100 PSI with a fan tip, no zero-degree nozzle). We use a soft wash method with manufacturer-approved cleaning solutions that remove mold and stains without damaging the surface or voiding your warranty.

It can if done incorrectly. Too much pressure or the wrong nozzle will gouge, etch, and furrow wood grain — leaving the surface rougher and more prone to splintering than before. Our crew uses the right PSI, tip size, and technique for each wood type. We also keep the nozzle at the correct distance and angle to clean effectively without damaging the wood.

Most projects run $1 to $3 per square foot, depending on size, condition, and material. A typical 300 sq ft deck costs $300-$900 for a full cleaning. Heavy mold buildup, old stain that needs stripping, or extensive red clay staining pushes costs toward the higher end. We provide a quote after seeing your deck.

Absolutely. Stain will not penetrate or bond properly to a dirty surface. Dirt, mold, mildew, old flaking stain, and pollen all create a barrier that prevents the new stain from soaking into the wood grain. The result is uneven color, poor adhesion, and a finish that peels or wears off within months. Cleaning is always the first step in any staining project we do.
