Frequently Asked Questions

Koi pond pricing varies based on size and features. A small 6×8 ecosystem pond runs $12,000-$15,000, medium 8×11 koi ponds range from $16,000-$20,000, and large 11×16 ponds run $22,000-$30,000. Larger estate ponds can be $46,000-$60,000+. Use our pricing calculator for a personalized estimate based on your specific needs.

Most residential koi ponds are completed in 5-7 days, depending on size and complexity. This includes excavation, liner installation, rock work, plumbing, and initial startup. Larger estate ponds may take 2-4 weeks. Weather can occasionally affect the timeline.

A healthy guideline is 1 inch of fish per 10 gallons of water. For example, a 1,000-gallon pond can support about 100 inches of fish—roughly 5-8 medium-sized koi. We design filtration systems to support your fish-keeping goals and can advise on stocking levels during your consultation.

Yes! Koi are cold-hardy fish and can survive Philadelphia winters. We design ponds with adequate depth (2+ feet) so fish can retreat to warmer bottom water. A floating de-icer maintains a hole in the ice for gas exchange. Fish enter torpor (a dormant state) and don't need feeding when water is below 40°F.

We incorporate several predator deterrents: fish caves and tunnels for hiding spots, steep pond edges that make wading difficult, and strategic rock placement. Additional options include motion-activated sprinklers, decoy herons, and netting during migration seasons.

Our ecosystem approach handles this naturally. The combination of mechanical filtration (skimmer), biological filtration (waterfall filter with beneficial bacteria), aquatic plants, and proper fish stocking creates a balanced system. Weekly maintenance takes just 5-30 minutes—mainly emptying the skimmer basket and checking equipment.

No! Moving water prevents mosquitoes from breeding, and koi love eating mosquito larvae. A properly designed ecosystem pond actually reduces mosquito populations in your yard compared to having no water feature at all.

A disappearing waterfall is a recirculating water feature where water cascades over rocks and disappears into an underground reservoir rather than collecting in a visible pond. You get the sight and sound of a waterfall without the maintenance of a fish pond. It's ideal for smaller spaces, front yards, or families with safety concerns.

Disappearing Waterfalls are the lowest-maintenance water feature we offer. Maintenance typically involves occasionally topping off water (especially in summer), removing debris from the vault area 1-2 times per year, and winterizing the pump if desired. Most owners spend less than an hour per month on maintenance.

Disappearing waterfalls typically range from $7,500-$15,000 depending on size, height, and rock selection. They're generally less expensive than fish ponds of comparable visual impact.

Converting a disappearing waterfall to a fish pond is possible but involves significant reconstruction. If you think you might want fish in the future, we recommend starting with a pond design. Alternatively, a disappearing stream that terminates in a small pond can give you the best of both worlds.

We install a wide variety: bubbling rock fountains, urn and vase fountains, tiered classical fountains, wall fountains, and custom sculptural pieces. Fountainscapes (our term for professionally installed decorative fountains) range from simple single-rock bubblers to elaborate multi-fountain groupings.

Fountain installations typically range from $5,500-$10,000. Price depends on the fountain style, size, and complexity of the installation.

Yes, fountains require electricity to power the pump. We install a dedicated outdoor-rated electrical connection as part of the project (by a licensed electrician if needed). Operating costs are minimal—most fountain pumps use less electricity than a standard light bulb.

Fountains are low-maintenance: occasional water top-offs (weekly in summer), pump cleaning 2-4 times per year, and winterization in freezing weather. We recommend adding a water treatment to prevent algae and mineral buildup. Total time is typically 15-30 minutes per month.

Yes! We offer comprehensive maintenance programs including spring cleanouts, summer maintenance visits, fall netting and preparation, and winterization. Choose from individual seasonal services or all-inclusive annual packages that cover everything your pond needs throughout the year.

Our spring cleanout is a complete pond refresh: we drain the pond, relocate fish to a holding tank, power wash rocks and gravel, clean the skimmer and biological filter, inspect all equipment, refill with fresh water, add beneficial bacteria and water treatments, and safely return your fish.

At minimum, we recommend a professional spring cleanout and fall winterization. Many pond owners also benefit from summer maintenance visits (especially for algae control) and periodic equipment checks. Our annual maintenance packages provide worry-free year-round care.

Absolutely! We design our ponds for easy owner maintenance. Weekly tasks (5-30 minutes) include emptying the skimmer basket, feeding fish, and quick visual inspections. We provide training at startup and are always available to answer questions. Many owners handle routine care themselves and hire us for seasonal cleanouts.

For winter: stop feeding fish when water drops below 40°F, install a floating de-icer to maintain a hole in the ice, move the pump shallower or turn it off depending on your setup, and remove any net. Never break ice by hitting it—the shock waves can harm fish. We offer winterization services if you prefer professional help.

It starts with a phone consultation to discuss your vision, followed by an on-site visit where we evaluate your space and discuss options. We provide a detailed proposal with design concepts and pricing. Once approved, we schedule construction (typically 2-4 weeks out). Installation takes 3-10 days depending on the project. We finish with a thorough walkthrough and maintenance training.

Yes, we require a deposit to secure your spot on our schedule and order materials. Typically this is 50% of the project total, with the balance due upon completion. For larger projects, we may arrange progress payments at key milestones.

We stand behind our work with comprehensive warranties: 3-year warranty on pumps and equipment, and a 1-year workmanship warranty covering construction defects. We also offer extended maintenance agreements that include equipment coverage.

We serve the greater Philadelphia region including Bucks County, Montgomery County, Chester County, Delaware County, Philadelphia, and South Jersey (Burlington, Camden, and Gloucester counties). For projects outside this area, please contact us to discuss availability.

Stormwater management involves controlling rainwater runoff to prevent flooding, erosion, and water pollution. Solutions include rain gardens, retention ponds, French drains, and permeable surfaces. These systems capture, filter, and slowly release stormwater rather than letting it rush off your property.

You might benefit from stormwater management if you experience: water pooling near your foundation, erosion in your yard, basement moisture after rain, soggy areas that never dry, or runoff issues affecting neighbors. Many municipalities also require stormwater controls for new construction or significant renovations.

Absolutely! Our specialty is creating stormwater features that are both functional and beautiful. Rain gardens become colorful native plant displays, retention basins can include waterfalls and fish, and dry creek beds add natural character. We design solutions that enhance your property while solving drainage problems.
