Green or black buildup
Shade, moisture, algae, and mildew can make boards look bad and feel slippery underfoot.
Deck cleaning before staining
Remove grime, mildew, algae, and buildup before staining, sealing, or restoration.
Deck washing is the broader cleaning service for removing dirt, mildew, algae, pollen, and surface film from boards, steps, railings, and landings. The cleaning method may include appropriate cleaners, agitation, controlled rinsing, or carefully managed pressure based on the wood and coating condition. The goal is a cleaner deck and a clear recommendation for what should happen next.
Best for: Decks with dirt, mildew, algae, pollen, slippery buildup, or surfaces that need cleaning before the next decision.
Deck washing is aimed at removable surface contamination—not failed stain, structural damage, or deep weathering by itself. These conditions are the clearest signs that cleaning is the correct starting point.
Shade, moisture, algae, and mildew can make boards look bad and feel slippery underfoot.
Stain over grime can trap contamination and create uneven results.
High-traffic areas often need cleaning before they are safe and ready for finish decisions.
Seasonal buildup can make a deck look older than it is and block proper finish evaluation.
Washing can reveal the true condition of the wood. Once dirt and buildup are gone, it is easier to decide whether stain, sealer, peeling prep, or restoration makes sense.
The surface is inspected first, then the cleaning method is matched to the wood, buildup, coating, and detail areas. After the deck dries, the next maintenance or finish recommendation can be made more accurately.

We check shade, mildew, algae, dirt, railings, steps, water absorption, and old finish condition.

The goal is to clean the wood without scarring boards or raising fibers from excessive pressure.

After cleaning and dry time, the deck may need stain, sealer, peeling prep, or restoration.
Deck washing is often the first step before deck staining, deck sealing, or deeper deck restoration. If the boards clean up well, the next step may be simple. If old stain is peeling or the wood is heavily weathered, we can explain the better path before you spend money on the wrong service.
If the deck needs a different service, we would rather tell you that up front than sell the wrong job.

A deck that looks hopeless may just be dirty. A deck that looks simple may hide peeling coating, moisture, or damaged boards. Cleaning helps reveal the real next step.
