Pond Services

From a brand-new pond to fixing one that won't hold water, one crew handles the digging, the liner, the stonework and the landscaping around it.

New Pond Installation

Ponds designed for your yard and built from the ground up: excavation, sand underlay, liner, stone edging and fill.

Pond Rebuilds & Leak Repair

Old pond losing water or falling apart? We dig it out, find the problem and rebuild it properly so it holds.

Liner Replacement

Torn, brittle or undersized liners pulled out and replaced with a new one-piece liner and fresh underlay.

Waterfalls & Streams

Natural stone waterfalls and streams that tie into your pond and keep the water moving.

Pumps & Filtration

Pumps, skimmers and filters sized for your pond so the water stays clear and circulating.

Fish-Friendly & Koi Ponds

Ponds built with the depth, circulation and filtration fish need to stay healthy year round.

Pond Clean-Outs

Muck, leaves and overgrowth cleaned out so your pond looks and works like new again.

Landscaping Around Your Pond

River stone, boulders, plantings, topsoil and sod around the pond so it fits the rest of your yard.

How we build a pond, step by step

An old pond dug out and rebuilt properly by our own crew and equipment.

  1. SD&G mini excavator digging out a pond and loading a tractor wagon near Ingleside, Ontario

    1. Dig out

    Old pond dug out with our mini excavator and the muck hauled away.

  2. Crew member raking a sand base inside a newly shaped pond

    2. Shape & sand base

    Bowl reshaped and lined with sand so nothing sharp touches the liner.

  3. Black pond liner laid over the excavated pond

    3. Lay the liner

    One-piece pond liner rolled out over the whole bowl and past the edges.

  4. Ring of boulders set on the pond liner as the pond fills with water

    4. Set the edge stones

    Boulders set around the shelf to hold the liner while it starts to fill.

  5. SD&G crew member filling the pond with a hose beside new river stone

    5. River stone & fill

    River stone placed over the liner by hand while the pond fills.

  6. Finished backyard pond with river stone edging, boulders and driftwood stumps near Ingleside, Ontario

    6. Finished

    Clear water, natural stone edge, boulders and stumps, with fresh soil graded around it.

Built to hold water

Why our ponds last

Sand underlay first

Rocks and roots are what puncture liners. A smooth sand bed under the liner protects it for years.

One-piece liner

No seams to open up. The liner runs past the edge of the pond so water can't wick out the sides.

Stone over the liner

River stone and boulders shield the liner from sun and frost, and make the pond look natural instead of plastic.

Graded edges

The ground around the pond is graded so rain runs away from it, not into it, keeping mud and fertilizer out of the water.
