Koi pond construction and water feature service for Los Angeles County
We've been driving into Los Angeles for pond work since the 1980s. Westside and hillside estates, Pasadena's historic gardens, Long Beach and South Bay homes, and hotel and studio-lot water features all sit on our regular construction and service calendars.
What shapes pond and water feature work in Los Angeles
Fill water
LADWP and the cities' own utilities blend soft Eastern Sierra aqueduct water with harder imported and groundwater supplies; hardness and chemistry vary by neighborhood, so we test the tap on the first visit everywhere in the county.
Heat, wind and evaporation
Marine-cooled on the Westside and South Bay, hot in the Valley, the San Gabriel foothills and the canyons. Hillside lots get wind that evaporates and splashes waterfalls; Valley ponds need depth and shade.
Predators and wildlife
Herons and egrets from the LA River, Sepulveda Basin, Ballona and Madrona Marsh; raccoons and coyotes in every hillside neighborhood; black bears in the foothill communities.

Customer story
A liner leak found the right way, in Long Beach
“They came back about three different times to make sure the leak was in the liner, without just saying, oh, we need to pull the liner out. It could have been a leak in the pipe. It's so clear, and you can hear the waterfall. I would recommend you guys to anyone. Fantastic job.”
Homeowner, Long Beach, CA
A Long Beach homeowner came home to an empty pond. Koi Pros came back three times to confirm the leak was in the liner and not the plumbing before recommending a new liner, then rebuilt the pond with the waterfall he can hear from the house.
