Your Backyard, Transformed by Water

There's a moment that happens with every pond we build. The water goes in, the pump comes on, and the whole backyard changes. The sound of moving water, fish gliding under lily pads, birds stopping to drink — a space that used to be ordinary becomes the place everyone gathers. That's what we build at Long Island Waterscapes.

I'm Angelo, the owner, and I'm on every single job. When you hire us, you're not getting a sales rep and a crew you'll never see again — you're getting me, personally designing and building a pond that fits your yard, your style, and how you actually want to live outdoors.

What Goes Into Every Pond We Build

A great pond isn't just a hole and a liner. It's an ecosystem — engineered so the water stays clear, the fish stay healthy, and you spend your time enjoying it instead of fighting it. Every pond we install includes:

Types of Ponds We Install

Ecosystem Ponds

Our most popular build. A balanced, naturalized pond with a waterfall, plants, fish, and biological filtration that work together to keep the water clear with minimal effort. It looks like a piece of nature dropped into your backyard.

Koi Ponds

Built deeper and with stronger filtration and aeration to keep prized koi healthy and vibrant year-round. If you want fish you'll name and feed by hand, this is the build for you. Learn more about our koi pond installation.

Ponds with Waterfalls & Streams

Add movement and sound with a cascading waterfall or a winding stream feeding into your pond. We also build pondless waterfalls for homeowners who want the sound of water without a standing pond.

What Does a Pond Cost on Long Island?

It's the first thing most people want to know — and the honest answer is that it depends. Because every pond is custom designed for your space, pricing varies with the size of the pond, the waterfalls and streams, the filtration system, and the surrounding stonework and landscaping. What we can promise is a clear, itemized quote with no surprises. For a detailed breakdown of what goes into pricing, see our pond installation cost guide for Long Island.

Pond Installation FAQs

How much does a pond cost on Long Island?

Every pond is custom designed, so pricing depends on size, waterfalls, filtration, and surrounding stonework. Most residential ecosystem ponds fall within a range we'll walk you through during your free consultation. See our pond installation cost page for a detailed breakdown.

How long does it take to build a pond?

Most residential ponds take three to five days, depending on size and complexity. Larger koi ponds or projects with extensive waterfalls and hardscape can take one to two weeks. Angelo gives you a realistic timeline during the consultation.

How much maintenance does a pond require?

A properly built ecosystem pond is largely self-sustaining. Expect a spring cleanout, occasional debris removal, and a fall winterization. We also offer full maintenance plans so you never have to think about it.

Can I keep koi and fish year-round on Long Island?

Yes. When a pond is built to the correct depth with proper aeration and filtration, koi and goldfish overwinter safely right here on Long Island. We design every koi pond with our climate in mind.
