Algae-Proof Your Florida Driveway: Pressure Washing Tips for Riverview, FL Homeowners

June 16, 2025

Florida’s tropical warmth and humidity mean our driveways rarely get a break from algae, mold, and mildew. As longtime Riverview locals—and as professionals who have pressure cleaned every kind of surface under the sun—we've learned there’s a real art and science to keeping your concrete looking clean, safe, and HOA-compliant all year round. In this blog, we’ll share specific, practical pressure washing tips for Riverview, FL homeowners looking to keep algae at bay for longer.

Why Is Algae So Persistent On Florida Driveways?

Algae, mold, and mildew thrive in warm, damp conditions—which describes the majority of our Riverview climate. We’re also surrounded by lush landscaping and seasonal rains, which keep driveways moist and shaded, making organic growth almost inevitable. Add sprinkler overspray, and those dark stains can reappear in record time.

Recognizing Algae, Mold, and Mildew

  • Black streaks: Usually mold or mildew, raising safety and aesthetic concerns.
  • Green patches: Typically algae, most common on shaded and damp areas.
  • Slippery surfaces: Algae and mold make driveways risky for slips and falls, especially near sidewalks and entrances.

Pressure Washing: More Than Just Blasting Water

We’ve seen it all—from homeowners renting a DIY unit on the weekend to professionals (like us) with powerful surface cleaners and proprietary solutions. But keeping algae at bay in Riverview requires more than just sprucing up the surface. Here’s how we recommend going about it:


1. Use a Professional Surface Cleaner

Pressure washing a driveway with a wand alone will leave unsightly streaks and miss deeply embedded spores. We always use a rotating surface cleaner (it looks like a big floor scrubber) to ensure every inch is agitated evenly. This tool also prevents etching or marking the concrete—a real risk with high psi focused in one spot.


2. Apply the Right Cleaning Solutions

For our initial rinse, we apply a mild chemical rinse that soaks into the pores of the concrete. The key is to use enough solution to kill residual mold, mildew, and algae, not just blast the visible part away. Allowing the solution to dwell for several minutes means deeper, longer-lasting cleaning results.


3. Don’t Forget the Sidewalks and Walkways

Most Riverview neighborhoods (and HOAs) expect sidewalks up to the property line to stay clean as well. These walks are often the first thing visitors and neighbors see, and they’re the most likely places to become slick and hazardous. Our standard service always includes these areas, because it makes a massive difference.

Pro Tips For Keeping Algae at Bay

  • Trim Landscaping: Give your driveway as much sunlight as possible by trimming trees and bushes; sunlight dries out moisture where algae thrives.
  • Aim Sprinklers Carefully: Point sprinkler heads away from driveways and paths. Overspray accelerates algae growth, leading to more frequent cleanings.
  • Limit Fertilizer Runoff: Local lawn fertilizers are great for grass, but the nutrients promote algae on concrete surfaces, too. Sweep excess off your driveway after each application.
  • Schedule Cleanings Regularly: If you wait until algae is thick and dark, removal becomes much tougher and more expensive. In Riverview, we recommend pressure washing concrete surfaces at least once a year—sometimes even more for shaded or irrigated areas.

What Sets Professional Pressure Washing Apart?

There’s a world of difference between a hardware store pressure washer and what we bring to the job. Here’s what we’ve learned serving Riverview and the surrounding communities for 12+ years:

  • Deep Cleaning: Our commercial surface cleaners scrub into concrete pores to remove root structures of algae, not just the top layer. It’s a lot like pulling weeds—get the roots, not just the leaves.
  • Chemical Rinse: By applying a targeted cleaning solution after washing, we limit immediate regrowth—most DIY jobs skip this, and the results don’t last nearly as long.
  • Experience: Each concrete surface and situation is different. We adjust pressure, cleaning solutions, and technique for driveways, walkways, and decorative stone. Safety and cleaning effectiveness always come first.
  • Environmentally Responsible: Our solutions are formulated to break down safely, with methods tailored to reduce runoff and protect Florida lawns and landscaping.

What About DIY Pressure Washing?

There’s a certain satisfaction in tackling a dirty driveway on your own, but we’d be remiss if we didn’t share a few words of caution:

  • Surface Damage: Too much psi or the wrong tip can etch lines into your concrete that never come out.
  • Chemical Risks: Using household bleach or the wrong solutions can kill grass, harm pets, and actually eat away at your concrete over time.
  • Safety First: Slick surfaces and flying debris can be hazardous—always use steady, controlled equipment and wear closed-toe shoes.

If you’re up for the task, rent a professional-grade surface cleaner and an appropriate cleaning solution made specifically for concrete/driveways. Otherwise, trust a local expert for both a safer experience and a longer-lasting result.

Extending That "Just Cleaned" Look

Once your driveway is pressure washed and looks like new, here’s how to get the most out of it:

  • Spot treat small re-growth: Keep a mild, store-bought mildew remover on hand and address any small patches quickly.
  • Keep it dry: After rainfall, sweep away standing water. Consider adjusting driveway slope or drainage if you regularly have puddles.
  • Regular blowing or sweeping: A weekly sweep goes a long way towards removing leaf litter and organic food sources that encourage future growth.
