How to Maintain and Care for Concrete Outdoor Fountains

Concrete outdoor fountains add a touch of elegance and tranquility to any outdoor space, whether it’s a sprawling garden or a cozy backyard retreat. However, like any outdoor fixture, these concrete fountains require regular maintenance to ensure they remain in optimal condition year-round. Proper care not only preserves their beauty but also extends their lifespan, allowing you to enjoy the soothing sounds of flowing water for years to come. In this guide, we’ll explore essential tips on how to maintain and care for your concrete outdoor fountain.

Regular Cleaning Routine

Begin by removing debris such as leaves, twigs, and dirt from the fountain basin and surface. Use a soft-bristled brush or a gentle spray of water to dislodge stubborn grime. For tougher stains, mix a solution of mild soap or concrete fountain cleaner with water and scrub the affected areas using a soft brush. Rinse thoroughly with clean water afterward.

Preventing Algae Growth

Algae can quickly accumulate in outdoor concrete fountains, detracting from their appearance and clogging the pump. To prevent algae growth, consider adding an algaecide treatment to the water periodically. Place the concrete fountain in an area with adequate sunlight to discourage algae growth, as sunlight helps inhibit algae formation. For more information on sustainable practices for water features, you can refer to the American Society of Landscape Architects’ guidelines.


Before the onset of winter, it’s essential to winterize your concrete fountain to protect it from freezing temperatures. Drain the concrete fountain completely and disconnect the pump to prevent damage from freezing water. Cover the concrete fountain with a waterproof fountain cover or tarp to shield it from snow, ice, and debris during the winter months.

Pump Maintenance

Regularly inspect the fountain pump for any signs of damage or wear. Clean the pump intake and impeller to ensure proper water circulation. Lubricate the pump bearings as needed and replace any worn-out parts to prevent malfunctions and prolong the pump’s lifespan.

Sealing and Waterproofing

Apply a concrete sealer or waterproofing agent to the fountain surface to protect it from moisture damage and staining. Reapply the sealer annually or as recommended by the manufacturer.

Troubleshooting Common Issues

Sometimes, despite regular maintenance, issues can arise. Here are some common problems and how to address them:

  • Low Water Flow: Check for clogs in the pump or tubing and clean them thoroughly.
  • Leaks: Inspect the fountain for cracks or holes and seal them with a waterproof epoxy.
  • Noisy Pump: Ensure the pump is fully submerged and check for any debris blocking the impeller.


With proper maintenance and care, your concrete outdoor fountain can remain a stunning focal point of your outdoor space for years to come. By following these essential tips, you can ensure that your concrete outdoor fountain continues to function smoothly and retains its beauty season after season. With a little effort and attention to detail, you can enjoy the soothing ambiance of your fountain for many years of outdoor enjoyment.
