Leak Detection & Repair Services


Pond-Leak Repair is a critical part of keeping your pond functioning properly. First, it should be known that 90% of all leaks in the Old Bridge, Matawan, Monmouth, Middlesex & Ocean County-NJ area, occur in the stream and/ or waterfall edges. Check these areas for wet spots when the ground is dry. Leaks in these areas are likely due to the buildup of debris or plant growth in stream-forming dams. This raises the level of the water in the streams and consequently overflows the sides. Settling of rock—on the edges of streams and waterfalls pulls the liner down, subsequently allowing water to leak out the sides of the stream and/or waterfall.


Using the right pond-leak repair techniques and tools, these problems can usually be solved by adding additional soil, under the liner/rocks, to build up the edges of the stream. Never should rocks be used under the liner to build up the edges. This is asking for trouble and additional leaks. If there is water behind the liner where it attaches to the bio-falls at the head of the stream or waterfall, it is likely the seal at that spot has been compromised and will require professional repairs. If no leak is found in the stream/waterfall…Bummer!


The leak detection process in pond-leak repairs has just become much more difficult, timely, and expensive. At some point in the following process, it should be determined whether it would be more cost-effective to have the old liner professionally removed out of the pond(s) and replaced or continue to search for any leaks on your Old Bridge, Matawan, Monmouth, Middlesex & Ocean County-NJ area pond or water feature. Constants: If at any time it rains, no matter how little the amount, the process should be restarted at the last fully completed step. At least 24 hours should pass after rainfall before marking the level that the water stabilizes at. (Stops going down). Nothing, such as rocks, fish, or plants, is to be added, taken out, or even moved in the pond(s). It is critical all measurements are accurate and documented using a timeline. Example: “It took two days for the pond to drop 5 inches”.

1. Start by turning off the water feature. Fill the pond to the full or slightly overfull level. This should be 1 inch below the top of the skimmer opening or the level at which your drain or pond's low edge is located. In hot weather, an aerator may be used to provide sufficient oxygen levels for the fish in the pond(s). Ensure that water is at least 1” below the top of the skimmer opening. If it isn’t, fill that line.

2. Allow Pond to sit for 24 hours.

3. After 24 hours, be sure no water is moving from pond to pond or waterfall/stream to pond. If this is occurring, continue waiting until this stops.

4. Mark water level on skimmer or stone using a permanent marker or wax pencil.

5. Wait 24 hours and document what happens.

6. When the water level stabilizes (stops going down) for 24 hrs. Then document the water level in the pond(s) ****remember if it rains at all, and an additional 24 hours should be given before marking the stopping level of the water****.

7. The water level should not go down more than 1” past the top of the skimmer opening in 24 hours. If the water does go down past the full level on the skimmer, a leak is at the perimeter of the water level once the water stops going down for 24 hours. This could be a hole in the liner or a crack in the concrete pond/fountain. If water drops less than one inch, the leak is likely to occur due to the low edge in the liner.
