We Keep Your Pond Perfect

Whether you need a one-time spring opening or a full-season care program, the team at Scott Anderson Design is ready to keep your water features as clean and beautiful as the day they were installed.

Spring is the most critical time for your pond. Once water temperatures rise above 50°F, typically March through May on Long Island, we perform a thorough cleaning to remove winter debris, algae, and sediment and set your pond up for a healthy season. We safely hold your fish, drain and power-wash the pond, check all plumbing and filtration, and acclimate your fish back into their refreshed environment.

For ongoing peace of mind, our seasonal care plans keep your pond ecosystem balanced all year long. Every water feature is unique and should only be maintained by a certified professional. This ensures the long-term health of your pond fish, water, and plants.

We serve homeowners throughout Nassau County, including Bellmore, Merrick, Massapequa, Garden City, Oyster Bay, and Great Neck.

Common Questions

Pond Maintenance FAQ

When should I clean my pond?
Spring is the most important time to clean your pond. We recommend a thorough cleaning once water temperatures rise above 50°F, typically March through May on Long Island. This removes winter debris, algae, and sediment and sets your pond up for a healthy season.
How much does spring pond cleaning cost on Long Island?
Our basic pond cleaning starts at $500 for a small pond (7' x 10') and $900 for a large pond (12' x 14'). Our deluxe deep-clean service, which includes draining and power-washing, starts at $750 for a small pond. See the pricing tables above for full details.
How often do I need professional pond maintenance?
At minimum, we recommend one professional cleaning per year, ideally in spring. Ponds with heavy fish loads, lots of surrounding trees, or older filtration systems often benefit from two cleanings per year, spring and fall. Our team can assess your specific pond and recommend the right frequency.
Is algae in my pond a problem?
Some algae is natural and expected, but excessive algae can deplete oxygen levels and harm fish. During a professional cleaning we remove excess algae buildup and check that your filtration system is properly balanced to keep algae under control throughout the season.
How do I prepare my koi pond for winter on Long Island?
Fall pond closing is one of the most important maintenance steps for Long Island koi ponds. Remove the main pump, install a winter aerator near the surface, add a floating de-icer, switch to cold-water koi food below 50°F, and net the pond for leaves. We offer professional fall pond closing service throughout Nassau County.
