Pond Maintenance Cost Factors

Maintaining your backyard pond ensures it stays clean and extends its life. How much pond maintenance costs depends on various factors.

Size

Your maintenance costs will be affected by pond size. The larger the pond, the higher the maintenance costs. Some pond service companies may charge by the number of gallons, although square footage is more often used to determine price.

Size Average Yearly Maintenance Cost
Up to 80 square feet$300–$800
80–150 square feet$700–$1,500
150–300 square feet$900–$2,500
Over 300 square feet$1,500–$5,000

Type of Pond

Different types of ponds require different maintenance. Koi pond maintenance will cost more since you need to ensure the water is safe to keep koi fish alive. A natural pond that doesn’t use chemicals may be even more expensive to maintain, while detention and retention ponds, which hold and divert excess water, require less involved maintenance.

Type of PondAverage Maintenance Cost
Kai pond$500–$1,500
Natural pond$550–$2,000
Garden pond$250–$1,000
Detention or retention pond$450–$1500

Features

Adding features to your pond, such as fountains or waterfalls, can increase its maintenance cost. Water features with motorized pumps can add $300 to $600 to regular pond maintenance costs.

Season

Winterizing your pond can cost between $100 to $500 on average. The winterizing process includes cleaning the pond, removing the pump, adding cold-water bacteria, and preparing any fish for winter.

Draining/Refilling

In some cases, you may need to fully drain and refill your pond. While regular maintenance can help prevent the need to drain and refill, too much bacteria or buildup may make it the best choice.

Pond Size (Sq. Ft.)Average Cost To DrainAverage Cost To Refill
80$800–$1,000$600–$1,000
160$1,000–$1,500$1,200–$1,800
300$1,400–$1,800$2,200–$2,600
500$1,800–$2,200$3,800–$4,500

How Often Should You Maintain Your Pond?

A koi pond needs weekly maintenance to ensure the health of the fish. Most homeowners choose to do weekly maintenance themselves, which only takes a few minutes to test the water and add any necessary additives. Most backyard ponds will also benefit from professional seasonal maintenance to keep them in good shape.

Cost of Common Pond Maintenance Add-Ons

A koi pond service near you can perform additional services to keep your pond looking and functioning at its best. Some common add-ons include:

  • Pond dredging: $1.70 to $2.50 per sq. ft.

  • Liner repair: $125 to $800

  • Pump repair $50 to $400

  • Water testing: $100 to $200

  • Pressure washing: $0.30 to $0.80 per sq. ft.
