Dangers of pressure washing your deck and how to avoid them
Pressure Washing Your Deck? Here’s What Could Go Wrong

Don’t Ruin Your Deck:
Pressure washing is a fantastic tool for cleaning tough surfaces like driveways, sidewalks, and retaining walls — where strong water pressure blasts away dirt and stains effectively. But wood decks are different. They’re delicate and can easily be damaged by high pressure. What looks like a quick cleaning solution can quickly become a costly mistake. High pressure can splinter wood fibers, cause permanent surface damage, or even blast holes through decking boards. It can also force water deep into the wood, leading to long-term issues like mold, mildew, and rot. Because of these risks, decks require a gentler, specialized cleaning approach.
Before you start spraying, here’s what you need to know.
The Risks of Pressure Washing Your Deck
- Splintering & Surface Damage: Too much pressure damages the wood surface and ruins your deck’s look.
- Water Intrusion: High pressure drives water into the wood, leading to mold, mildew, and rot.
- Weakened Structure: Excessive pressure loosens nails and weakens railings — potentially unsafe!
