Losing water? We find leaks other companies miss — and fix them right the first time. Serving the entire Greater Philadelphia area.
Leaking pond? Here's what happens next
Call us or send photos.
The phone consultation is free. Text or email photos of the pond and where you think it is losing water, or call 215-880-6811. We respond within 1 to 2 business days.
On-site assessment
If the phone call points to an on-site visit, we schedule one. The on-site assessment carries a fee, and we tell you exactly what it is on the phone before we book anything, based on what your pond needs. No surprises when we show up.
Written options, repair and renovation.
You get a written proposal. Where a repair and a renovation are both realistic, we price both so you can compare.
One-year warranty on the work.
Repair and leak work is warrantied for one year, including on ponds we did not build.
Repairs are situational, so we quote them after diagnosis rather than publishing general prices. Renovations start at $3,000.
Signs Your Pond Has a Leak
Dropping Water Level
Losing more than 1–2 inches per week (beyond normal evaporation) indicates a leak.
Soggy Areas Around Pond
Wet spots or unusually lush grass near the pond edge suggest water escaping through the liner.
Pump Running Dry
Auto-fill valve running constantly or skimmer running low means water is leaving faster than normal.
Visible Liner Damage
Cracks, punctures, or displaced rocks exposing the liner are direct leak sources.
Our Diagnostic Process
Systematic, thorough, and accurate
Initial Assessment
We inspect your pond, measure water loss rate, and check all mechanical components (plumbing, skimmer, filter connections).
Fill & Monitor Test
We fill the pond to normal level and monitor over 24–48 hours with the pump off to isolate whether the leak is in the pond or the plumbing.
Systematic Isolation
We test each section — waterfall, stream, pond basin, plumbing lines — to pinpoint the exact leak location.
Repair & Verify
Once located, we repair using the appropriate method (liner patch, plumbing fix, edge re-seal) and verify the repair holds.
Common Leak Sources We Fix
Liner Punctures
Root penetration, animal claws, sharp rocks, or age-related deterioration. Repaired with EPDM patches or full liner replacement.
Plumbing Connections
Loose fittings at the skimmer, filter, or pump. Tightened and sealed with silicone or replaced.
Waterfall Splash-Out
Water splashing over the liner edge at the waterfall or stream. Fixed by adjusting rocks and raising liner edges.
Settling & Edge Creep
Ground settling causes the pond edge to drop, allowing water to escape. Re-leveled and re-sealed.
UV Degradation
Exposed liner breaks down from sun exposure. Covered with rock or replaced with fresh liner.
Cracked Skimmer/Filter
Plastic components can crack from freeze-thaw cycles. Replaced with new units.
