Service Area

Garden State Koi has been designing, installing, and maintaining custom water features throughout Orange County, NY since 1991. From our home base in Warwick, NY, we serve homeowners in Middletown, Newburgh, Goshen, Cornwall, Monroe, and Woodbury with ecosystem koi ponds, pondless waterfalls, fountainscapes, and recreational ponds.

Our service area extends into Rockland County — including New City, Nanuet, Spring Valley, Pearl River, and Haverstraw — as well as parts of Sullivan, Ulster, and Dutchess Counties. Whether you're looking for a koi pond installer in Poughkeepsie or pond maintenance in Monticello, we're here to help.

In New Jersey, we serve Sussex County communities like Sparta, Vernon, Newton, and Franklin, plus West Milford, Ringwood, and Hewitt in Passaic County. Need a pondless waterfall in Sparta or pond repair in Vernon? Garden State Koi is your local expert.

Our New Jersey work also runs south into Morris County (Chester, Mendham, Madison, Morristown, and Harding), Somerset County (Bridgewater, Warren, Bernardsville, Basking Ridge, and Far Hills), and Union County (Westfield, Summit, Scotch Plains, Mountainside, and Berkeley Heights). Terrain changes a lot across those counties — Highlands bedrock in Chester, Watchung slope in Warren and Summit, flat clay lots in Bridgewater — so each county page covers what that actually means for your build.

We also serve northeastern Pennsylvania, including Milford, Matamoras, Dingmans Ferry, and Hawley in Pike and Wayne Counties. Our team regularly installs and maintains water features throughout the Poconos region.

As a Certified Aquascape Contractor with over 1,000 water features installed, we bring 33+ years of expertise to every project. Our services include spring pond cleanings, seasonal maintenance memberships, pond repairs, LED lighting design, and complete water feature installations.
