How to Get Rid of Algae on Your Pavers Once and For All

Brick pavers add charm and elegance to driveways, patios, and pool decks, but in Florida's humid climate, algae growth is an all-too-common problem. Algae not only create unsightly green or black stains on your pavers but also make surfaces dangerously slippery when wet.

If you’re tired of constantly battling algae, this how-to guide will show you the most effective removal techniques and preventive strategies to ensure your pavers stay clean, safe, and algae-free for years to come.

Why Algae Grows on Brick Pavers

Algae thrive in warm, damp, and shaded environments, which makes Florida’s climate the perfect breeding ground. Here are the main factors contributing to algae growth on pavers:

Excess Moisture: Poor drainage or frequent rain creates damp conditions where algae flourish.
Lack of Sunlight: Shaded areas prevent the pavers from drying out properly.
Organic Debris: Leaves, dirt, and other debris trap moisture and feed algae growth.
Improper Sealing: Unsealed or poorly sealed pavers are more porous and prone to algae buildup.

Understanding these causes is key to tackling the issue at its root.

How to Remove Algae from Your Pavers: A Step-by-Step Guide

Removing algae requires a combination of the right tools, cleaning agents, and techniques to ensure it doesn’t return anytime soon.

Step 1: Gather Your Supplies

Before starting, make sure you have the following tools and materials:

Stiff-bristle brush
Garden hose or pressure washer (1,000–1,500 PSI)
Algae-specific cleaner or pH-neutral cleaner
Protective gloves
Safety goggles

Step 2: Remove Loose Debris

Use a broom to sweep away leaves, dirt, and any loose debris from the pavers. This prevents organic matter from interfering with the cleaning process.

Pro Tip: Start with dry pavers for the best results.

Step 3: Apply an Algae Cleaner

Choose a commercial-grade algae remover specifically designed for pavers.
Follow the instructions on the product for dilution and application.
Apply the cleaner evenly across the algae-affected areas.

DIY Option: Mix one part white vinegar with three parts water for a natural cleaning alternative. Avoid using bleach, as it can damage pavers and surrounding vegetation.

Step 4: Scrub the Pavers

Use a stiff-bristle brush to scrub the affected areas vigorously.
Pay extra attention to joints and crevices where algae can hide.

Pro Tip: Avoid using wire brushes, as they can scratch the surface of your pavers.

Step 5: Rinse Thoroughly

Use a garden hose or pressure washer on a low-pressure setting (1,000–1,500 PSI) to rinse away the algae and cleaning solution.
Ensure all residue is washed away to prevent future growth.

Warning: Too much pressure can damage the surface of your pavers and dislodge joint sand.

Step 6: Let the Pavers Dry Completely

Allow the pavers to dry fully in the sun.
Algae are less likely to grow on dry, well-ventilated surfaces.

How to Prevent Algae Growth on Brick Pavers

Removing algae is just one part of the battle. To keep your pavers algae-free in the long run, follow these preventive strategies:

1. Ensure Proper Drainage

Check your drainage system regularly to prevent water from pooling on your pavers.
Adjust the grading if necessary to allow water to flow away from the surface.

2. Keep the Area Clean

Sweep your pavers frequently to remove leaves, dirt, and organic debris.
Trim overhanging trees or plants to reduce shade and allow sunlight to reach the pavers.

3. Schedule Regular Deep Cleaning

Plan for a professional cleaning service at least once a year to keep algae at bay.
Professionals use specialized equipment and treatments that are more effective than DIY methods.

4. Apply a High-Quality Sealer

Sealing your pavers creates a protective barrier against moisture and algae growth.
Choose a breathable, algae-resistant sealer suitable for Florida’s climate.
Reseal your pavers every 2–3 years to maintain optimal protection.

5. Increase Sunlight Exposure

If possible, remove or trim large plants and trees that cast heavy shade on your pavers.
More sunlight means drier surfaces—and fewer opportunities for algae to grow.
