How much does deck or fence pressure washing cost?
Washing a deck or fence takes more care than a driveway. Wood can splinter or gouge under high pressure, so pros use lower pressure and a cleaner. That slower approach is why decks and fences cost more per square foot than concrete.

What's usually included
- Furniture and grills moved off the deck
- Wood or composite cleaner applied to lift dirt and mildew
- Low-pressure rinse following the grain of the boards

What changes the price
- Square footage. Count both sides of a fence if you want both washed.
- Material. Soft woods like cedar need extra care, while composite usually washes faster.
- Mildew and algae. Shady decks with green or black growth need more cleaner and time.
- Railings and stairs. Spindles and steps take far longer than flat decking.
Do it yourself or hire a pro?
You can wash a deck yourself with a rented pressure washer, but it is easy to raise the grain or carve marks into the wood if you hold the tip too close. Use a wide fan tip, low pressure and a deck cleaner. If you are not confident, a pro wash is cheaper than repairing damaged boards.
Common questions
Will pressure washing damage my deck?
It can if done with too much pressure. A good pro uses low pressure and cleaner, and works with the grain.
How long should I wait to stain after washing?
Most stain makers say to let the wood dry for at least a day or two. Check the label on your stain.
Can composite decks be pressure washed?
Many can, at low pressure. Check your decking maker's care guide first, since some limit pressure or nozzle type.
