Custom Pond Builders Serving Long Island
At Long Island Waterscapes, pond installation is our foundation. Owner Angelo has been designing and building custom ponds on Long Island since 2007 — starting with weekend pond cleanings and growing into one of the most experienced water feature builders on the Island.
We build every type of pond: natural ecosystem ponds, koi ponds, reflection ponds, goldfish ponds, and pond-and-waterfall combinations. Every project is custom designed for your specific property, your lifestyle, and your budget.
Types of Ponds We Build
Ecosystem Ponds
A properly built ecosystem pond works with nature — not against it. Using a combination of biological filtration, aquatic plants, beneficial bacteria, and natural stone, we build ponds that stay clear and healthy with minimal effort on your part. These ponds attract birds, frogs, and dragonflies, creating a living ecosystem in your backyard.
Koi Ponds
Koi ponds require specific depth, filtration, and aeration to keep fish healthy year-round on Long Island. We design koi ponds with properly sized skimmers, biological filters, UV clarifiers, and bottom drains to ensure crystal-clear water and happy, thriving fish. See our dedicated koi pond installation page for details.
Pond and Waterfall Combinations
Most of our pond installations include a waterfall or stream — and for good reason. Moving water aerates the pond naturally, prevents stagnation, and adds the sound and movement that makes a water feature truly come alive. We design waterfalls and streams that look completely natural within your landscape.
Pondless Systems
Want the look and sound of a waterfall without the pond? Our pondless waterfall systems are ideal for smaller yards, families with young children, or homeowners who want minimal maintenance.

Frequently Asked Questions
How much does a pond installation cost on Long Island?
Pond installation costs vary based on size, features, and complexity. A small ecosystem pond typically starts around $8,000–$15,000. A larger pond with waterfall and professional landscaping can run $20,000–$50,000+. Angelo provides detailed quotes after visiting your property — no guessing, no surprises.
How long does it take to install a pond?
Most residential pond installations take between 2–5 days depending on size and complexity. Larger estate projects or ponds with extensive waterfalls and streams may take longer. We'll give you a realistic timeline during your consultation.
Do you install ponds in the Hamptons?
Yes — the Hamptons and East End are a core part of our service area. We build luxury ponds and waterfalls for estate properties in Southampton, East Hampton, Sag Harbor, Bridgehampton, Water Mill, Amagansett, and surrounding communities. See our Hamptons pond installation page.
Will my pond stay clear without constant maintenance?
A properly built ecosystem pond is largely self-sustaining. The right combination of biological filtration, plants, and beneficial bacteria keeps the water naturally balanced. We also offer seasonal maintenance plans to handle spring startups, fall cleanouts, and anything in between.
