Pond Leak Detection & Repair

Normal evaporation in summer is 1–2 inches per week in the Philadelphia area. If you're losing more than that — especially in cooler weather — it's likely a leak. The bucket test helps: place a bucket of water next to your pond and compare water loss over 24 hours.

Simple liner patches or plumbing fixes typically cost $300–$800. More complex repairs involving liner replacement, extensive rock work, or settling correction range from $1,500–$5,000+. We provide a detailed estimate after diagnosis.

Minor liner punctures can sometimes be patched with an EPDM patch kit. However, most leaks are difficult to locate without experience, and improper repairs often cause more damage. We recommend professional diagnosis.

Most leak diagnoses take 2–4 hours on-site. Complex cases with multiple potential sources may require a 24-48 hour fill-and-monitor test.

Not always. We start with non-invasive testing. If the leak is in the pond basin, we may need to lower the water level to the leak point. We safely relocate fish if draining is necessary.

Yes — we repair ecosystem ponds, koi ponds, formal ponds, disappearing waterfalls, and fountains. We work with EPDM, PVC, concrete, and fiberglass pond systems.
