    Three kinds of work, one crew

    Design and build, scheduled care, and repair. Most clients use all three over the life of a feature.

    Design & build

    New ponds, waterfalls and fountains, plus renovations that fix what was skipped the first time.

    Care

    Scheduled maintenance, clean-outs, algae control, lakes and koi handling.

    Repair

    Pumps, filters, liners, plumbing, electrical and methodical leak detection.

    Every service, in detail

    Koi Pond Construction

    A koi pond that stays clear for twenty years is engineered before the first shovel hits dirt: depth, bottom drains,...

    Pond & Water Feature Design

    Good design makes the pond look natural and run quietly. We plan circulation, filtration and service access first,...

    Waterfall & Stream Construction

    A waterfall is a plumbing project wearing rock. Flow rate, weir width, drop height and basin sizing decide whether...

    Pondless Waterfalls

    Water falls over rock, disappears into a gravel-covered basin, and recirculates. No standing water, no algae to...

    Fountain Installation & Repair

    From a courtyard tiered fountain to a floating aerating fountain on an HOA lake, we install, fix and maintain the...

    Pond Maintenance Plans

    Ponds rarely fail suddenly. Filters clog a little, nitrates creep up, a pump loses flow, and one hot week later the...

    Pond Cleaning & Clean-Outs

    A full clean-out resets a pond that has fallen behind: sludge, muck and dead plant matter out, filters rebuilt, and...

    Pond Repair

    We repair the whole system, not just the part that broke: if a pump failed because the filter was undersized,...

    Leak Detection & Repair

    Most 'liner leaks' are actually a low edge, a splash-out at the falls, a bad skimmer seal or a plumbing joint. We...

    Pond Resealing & Relining

    When a concrete pond, plaster fountain or old liner is failing in more than one spot, a new waterproof layer costs...

    Pond Renovation & Reconstruction

    Inherited a pond with the house? Built one that never quite worked? Renovation keeps what's sound and fixes what was...

    Waterfall Repair

    Waterfalls are the most common leak point on a pond and the most common reason a pump seems 'too weak.' Both are...

    Lake & Large Pond Management

    A lake is an ecosystem with a budget line. We manage oxygen, nutrients, vegetation, fish populations and equipment...

    Algae & Weed Control

    Green water, string algae and pond weeds all come from the same three inputs: nutrients, sunlight and still water....

    Shoreline Restoration

    Eroding banks silt in the lake, undercut walkways and eventually become a liability claim. We rebuild edges with a...

    Koi Transport & Holding

    Whether you're renovating, moving house, or resealing a fountain that happens to have fish in it, the koi need...
