Moss and Algae Removal for Walkways, Patios and Shaded Paths

Edwardsville Power Washing · 2026-08-15

Shaded walkways, north-facing patios, and paths under tree cover build up moss and algae fast in this climate -- and once it's established, it doesn't just look bad, it gets genuinely slippery when wet. That's the version of this problem we hear about most: not "I want it to look nicer" but "someone almost fell on this."

Why shaded paths are worse than the rest of the yard

Moss needs moisture and shade to establish, and a path that doesn't get direct sun for most of the day rarely dries out fully between rains. Add tree sap, pollen, and fallen leaves breaking down on the surface, and you've got exactly the conditions moss and algae need to spread.

What we actually do

• Pressure wash the surface to physically lift the moss, algae, and embedded organic buildup
• Match pressure to the material -- stone, pavers, and stamped concrete each take a different approach so the surface isn't damaged in the process
• Clear grout lines and paver joints where moss tends to regrow first if it's left behind

Property types this covers

• Wooded or heavily shaded residential lots
• Side yards and back paths that rarely get direct sun
• Stone or paver patios under mature tree cover
• Walkways that stay damp longer than the rest of the property after rain
