Slip and fall accidents are one of the most common causes of liability claims for property
owners and businesses. And while you can’t control every hazard, one of the most
preventable causes, algae, moss, and biological growth on walkways, is entirely within
your control.
What Makes Walkways Slippery
Concrete, pavers, and stone all develop biological growth over time, especially in shaded
or moist areas. Algae forms a thin, almost invisible film that becomes extremely slippery
when wet. Moss is thicker and retains moisture, creating a soft, uneven surface that’s
dangerous underfoot. Neither is obvious until someone is already on the ground.
The Legal Reality
Property owners and businesses have a legal duty to maintain safe premises for visitors.
If someone slips and falls on algae-covered walkways that you knew or should have
known about, you can be held liable for their medical costs, lost wages, and pain and
suffering. A single claim can easily run into tens of thousands of dollars. Regular
cleaning of walkways is one of the most basic and defensible forms of premises liability
management.
High-Risk Areas to Prioritize
Some areas carry more risk than others and should be prioritized in any cleaning
schedule: building entrances where foot traffic concentrates, pool decks and areas
around water features, north-facing walkways that stay shaded and damp longer, areas under trees where leaf debris accumulates, and any outdoor steps or ramps.
How Often Should Walkways Be Cleaned?
For commercial properties with significant foot traffic, quarterly pressure washing of
walkways and entrances is a reasonable minimum. For residential properties or HOA
communities, semi-annual cleaning typically keeps biological growth in check. Areas
with heavy shade or moisture exposure may need more frequent attention.
The cost of regular cleaning is a fraction of the cost of a single liability claim. It’s not just
about appearances; it’s risk management.
Conclusion
Keeping walkways clean is one of the simplest ways to reduce risk and protect both
visitors and property owners. Regular removal of algae, moss, and buildup not only
improves appearance but also helps prevent dangerous slip hazards before they become
a liability issue. Staying proactive with routine cleaning is far more cost-effective than
dealing with an accident after the fact.
