Pond repair technicians for pumps, filters, liners, plumbing and electrical
We repair the whole system, not just the part that broke: if a pump failed because the filter was undersized, replacing the pump alone buys you six months.
What we repair
- Pumps: submersible and external, including correct sizing on replacement
- Filters and skimmers: media, baskets, bulkheads, gravity-fed and pressurized systems
- Liners: EPDM patching, seam repair, polyurea spray-in overlays
- Plumbing: cracked PVC, check valves, bottom drain fittings, auto-fill valves
- UV clarifiers, aeration and lighting
- Electrical: GFCI trips, timers, controllers and conduit
- Rockwork, edging and waterfall weirs that have settled or shifted
Emergency response
Pump failure in July can kill fish in a day. Call us and we'll get an aerator on-site while the repair is scheduled. Commercial maintenance clients get priority dispatch.
Signs you need repair help
- The pump trips the breaker or runs hot
- Flow has dropped and cleaning the filter doesn't bring it back
- The liner shows a tear, bubble or exposed seam
- A fitting or valve drips or the auto-fill never shuts off
- Lights or the UV are dead
What drives the cost
Diagnostic visits are a flat fee; repairs are quoted on-site with parts. Pump and UV replacements vary with size, and liner repairs depend on whether a patch will hold or the liner needs a polyurea overlay. We carry common pumps, seals and fittings so most repairs are completed on the first visit.
What this service covers
Pond repair sits under the wider heading of water feature repair. Clients tend to call it pond fix or koi pond repair service; whatever the name, the work breaks down into a few distinct jobs:
Pump repair and replacement
Submersible and external pumps repaired or replaced with correct sizing for head and flow.
Filter and skimmer repair
Cracked boxes, failed bulkheads, collapsed media and broken weir doors.
Liner patching and seam repair
EPDM patches and seam tape, or polyurea overlays for liners with multiple failures.
Plumbing and valve repair
Cracked PVC, stuck check valves, bottom-drain fittings and auto-fill valves.
UV and aeration repair
Lamp, ballast and quartz-sleeve replacement; diffuser and compressor service.
Pond electrical and GFCI
Tripping GFCIs, timers, controllers, lighting and conduit repaired to code.
Rock and edge repair

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.
Watch: a waterfall and pond repair and reseal in Orange County

Questions about repair
My pond pump stopped working. What should I do first?
Check the GFCI outlet and the pump intake for debris. If it still won't run, call us. Keep the fish oxygenated with a hose spray or air pump in the meantime.
Can you repair a concrete pond that's cracking?
Yes. Depending on the cause we either epoxy-inject and reseal, or overlay the shell with a flexible polyurea membrane.
