Slippery sidewalks aren’t just ugly—they’re dangerous, expensive, and completely avoidable.
If you own a home, rental, or business property, those dark, slick patches on your concrete and walkways are more than a cosmetic issue. They’re a slip-and-fall accident waiting to happen.
In the Pacific Northwest, where we deal with constant moisture, shade, and moss, this problem is even worse. The good news? Regular professional pressure washing is one of the simplest ways to dramatically reduce your risk and protect your family, guests, customers, and wallet.
In this guide, we’re going to break down:
– Why sidewalks get so slippery in the first place
– How moss, algae, and grime increase your liability risk
– Why DIY methods usually fail
– How regular pressure washing keeps people safe and protects your property
– A simple schedule to keep sidewalks clean year-round

Why Sidewalks Get Slippery (Especially in the Pacific Northwest)
Our climate is a breeding ground for slippery surfaces. Over time, your sidewalks, walkways, driveways, and paths build up:
– Moss and algae
– Mold and mildew
– Dirt, grime, and oil
– Decomposing leaves and organic debris
These create a slick surface—especially when wet.

The Real Risk: Slip-and-Fall Accidents Aren’t Just Bad Luck
A slip can lead to sprains, fractures, and head injuries. Beyond that, neglecting slippery walkways can open you up to liability if someone gets hurt on your property.

Why Regular Pressure Washing Is a Safety Investment
Professional pressure washing:
– Removes moss, algae, mildew, and slime
– Restores traction
– Reduces your liability
– Extends the life of your concrete
– Boosts curb appeal

DIY vs Professional Pressure Washing
DIY equipment is often too weak—or too strong and causes damage. Professionals bring the right tools, technique, and detergents to safely clean your surfaces.

Where Slippery Surfaces Hide
Common areas include:
– Front walkways
– Street sidewalks
– Driveways
– Side paths
– Steps
– Patios and pavers
– Pool decks
If it looks green or shiny when wet, it’s a hazard.
