A wood deck that was golden a few years ago turns gray, then green, then slippery. A white vinyl fence picks up a green film along the bottom and orange clay where the mower throws it. Both are common around Statesville, and both clean up well when it's done carefully.
Wood is softer than you think
The biggest mistake with decks and fences is too much pressure. Pressure-treated pine, cedar and other deck woods are soft. A high-pressure wand tears up the surface fibers, leaves a fuzzy texture, and can carve permanent lines into the boards. That damage shows even more once the wood is stained.
Wood should be cleaned with a low-pressure soft wash approach and only as much rinse pressure as the wood can handle.
How a wood deck gets cleaned
- Clear and protect. Furniture, grills and planters come off the deck. Plants around and under the deck are pre-wetted.
- Clean. The crew applies a wood-safe cleaning solution that breaks down mildew, algae and dirt. For heavy growth, a mild bleach-based solution may be used. For general gray weathering, an oxygen-based wood cleaner is often the better choice.
- Rinse gently. The wood is rinsed with low pressure, working with the grain.
- Brighten. Wood brightener is applied after cleaning. It's a mild acid that restores the wood's natural color and neutralizes the cleaner. This step is what takes gray boards back toward their original tone.
- Final rinse. Everything is rinsed, including plants and nearby siding.
Most decks take two to four hours, depending on size, railings and stairs.
Composite decks
Composite and PVC decking don't turn gray like wood, but they do grow mildew and collect pollen and dirt in the grooves. They're also sensitive to high pressure, which can scar the surface. Composite should be cleaned with appropriate cleaners and low pressure.
Wood fences
Wood fences go gray and green, especially on the shady side. They get cleaned the same way as decks: low pressure, wood-safe cleaner, brightener and a gentle rinse. Both sides of the fence get cleaned if the crew can reach them. If a neighbor's side is involved, mention it when you call so the crew can plan for access.
Vinyl fences
Vinyl fences are easier. A soft wash with a mild bleach-based solution removes the green and gray film quickly. Red clay splash along the bottom rails usually comes off well, though deep-set stains may need extra treatment.
Staining and sealing after cleaning
If you plan to stain or seal your wood deck or fence, cleaning first is the right move. Stain won't bond well to mildew, dirt or gray, dead wood fibers.
The important part is waiting. Wood needs to dry completely before stain or sealer goes on. In Statesville, that usually means at least two to three days of dry weather, and longer in humid stretches or on shaded decks. A simple test: sprinkle a little water on the boards. If it beads up or sits there, wait. If it soaks in, the wood is usually ready.
How often to clean
Most decks and wood fences around here benefit from a cleaning every year or two. Shady decks and fences near tree lines tend to need it more often. A clean before spring cookout season, after the yellow pollen settles, works well for most homeowners.

A deck cleaning pairs naturally with a patio or walkway cleaning from driveway and concrete cleaning, and with a house wash so the back of the house matches the clean deck. If your deck sits under gutters that overflow, gutter cleaning can help prevent the mildew from coming right back.

Questions people ask
Will cleaning damage my wood deck?
Not when it's done with low pressure and the right cleaners. Damage comes from high-pressure wands that tear up the wood fibers. A good crew lets the cleaning solution do the work and rinses gently with the grain.
Can you make my gray deck look new again?
Cleaning plus wood brightener takes a lot of the gray out and brings back much of the natural wood tone. Very old or deeply weathered wood won't look brand new, but most decks look dramatically better.
How long should I wait to stain after cleaning?
Wait until the wood is fully dry, usually at least two to three days of dry weather in Statesville and longer during humid stretches. If water sprinkled on the boards soaks in, the wood is usually ready.
Do you clean both sides of a fence?
Yes, if the crew can access both sides. If the other side faces a neighbor's yard, mention it when you call so access can be planned.
