Protect Your Guests and Your Peace of Mind

Patio & Walkway Cleaning: How Slippery Surfaces Increase Liability

The Danger of 'Invisible' Algae

•
Wet Weather Hazard: Algae becomes incredibly slick when wet, even if it's not visible when dry.
•
Liability Concerns: Homeowners are responsible for maintaining safe walking surfaces, including public sidewalks, for visitors and mail carriers.
•
Structural Damage: Roots from moss and weeds can crack pavers and lift walkways over time.
•
Decreased Curb Appeal: Dirty walkways make a home look poorly maintained to potential buyers and neighbors.

Our Safety-First Cleaning

Restoring grip and beauty:

•
Deep Scouring: We remove the deep-seated organic matter and follow up with professional surface sealing to prevent regrowth.
•
Sanitization: We kill the spores that lead to quick regrowth of moss and algae.
•
Safe for Pavers: We use techniques that preserve the joint sand and structural integrity of your walkways.
•
Post-Clean Inspection: We ensure every square inch is clear and safe for foot traffic.
