Pond Repair and Renovation Services in Cranston, Rhode Island

Leak detection is the most common request. A pond that loses inches a day usually has a problem in the waterfall, a low spot on the edge, or a failed fitting rather than a hole in the middle of the liner. We test each area before deciding what to fix.

Beyond leaks, we replace worn liners with 45 mil EPDM, rebuild settled waterfalls and streams, add a skimmer or biological falls to ponds that never had real filtration, deepen shallow ponds so fish can overwinter, and install fish caves, auto-fill valves, and lighting. Preformed or kit ponds can be converted into true ecosystem ponds.

Cranston soils are mostly sandy and loamy, which drain well but let rocks settle along the edges over time. When an edge sinks, the liner can fall below the waterline and the pond leaks over the rim. Freeze and thaw cycles add frost heave, which can push stone into a liner or shift a waterfall box.

Fall leaf drop is another factor. Ponds without a skimmer fill with leaves that rot into muck. Our crew travels from Cherry Valley, Massachusetts, and schedules Rhode Island work in blocks, so diagnosis, repair, and follow-up visits are grouped together.

Small repairs, such as fixing a leak at the edge or replacing a pump, run roughly $1,300 to $3,750. Mid-size renovations, like rebuilding a waterfall or adding a skimmer, run roughly $3,750 to $5,000. Full renovations run $5,000 and up, and a complete rebuild can be considerably more.

When the cause is not obvious, we usually begin with an Exploratory Drain and Clean, roughly $1,300 to $2,500. With the pond empty, we can inspect the liner, plumbing, and rockwork directly. Liner condition, stone removal, and how much filtration needs to be added move the number most.

Call and tell us what the pond is doing, and photos help. Shawn then schedules a Discovery Meeting during our next Rhode Island block to inspect the pond, waterfall, and equipment in person.

If the issue is clear, you get a plan and range. If not, the crew does the drain and clean, moving fish to a holding tank in their own water. After repairs, the pond is refilled with dechlorinated water, fish are temperature matched before going back in, and the pump and waterfall are tested.
