Slip hazards: What causes it and how we can fix them
Don’t let algae and moss ruin your morning coffee!
Slippery patios and driveways are a major concern for homeowners in Coquitlam, Port Coquitlam, and across Metro Vancouver, especially during rainy months.
What causes slippery surfaces?
Most slip hazards come from:
Algae and moss buildup
Mold and mildew films
Leaf tannins and organic stains
Smooth concrete sealed with grime
These thrive in shaded, damp areas — common in the Tri-Cities and North Vancouver.
Why it’s more than an inconvenience
Slips can lead to:
Injuries for family and guests
Liability concerns
Reduced usability of outdoor spaces
It’s especially risky on steps, pool decks, and sloped driveways.
DIY fixes
Homeowners often try:
Sweeping and hosing
Vinegar or bleach mixes
Rental pressure washers
These may help short-term, but growth often returns quickly if roots and spores aren’t treated.
Professional cleaning solutions
Professional patio and driveway cleaning focuses on:
Deep removal of organic growth
Treatments that kill spores
Even pressure that won’t damage concrete or pavers
Restoring natural traction
In wet regions like Coquitlam and North Vancouver, this dramatically improves safety.
Prevention tips
To keep surfaces safer:
Trim back overhanging trees
Keep debris cleared
Improve drainage
Schedule routine exterior cleaning
The takeaway
If your patio or driveway feels slick, it’s not just dirt — it’s organic growth thriving in our coastal climate. Proper cleaning restores grip and keeps your outdoor spaces safe year-round.
