Let’s make your Hamptons landscape everything you want it to be!

Your landscape can be the perfect setting to enjoy delightful family gatherings, bask in the glorious sunshine, unwind in a soothing space, or all that and more. Whatever you wish for, Mahoney’s designers and craftsmen will create your luxurious new landscape.

Mahoney’s LIFETIME WARRANTY covers all newly installed trees and shrubs.

If we plant it and continuously maintain your newly installed landscape, you won’t have to pay twice for your trees and shrubs—we guarantee it. If a tree or shrub fails to thrive, we’ll replace the plant material at no cost.

Cultivating excellence from the ground up.

Our extensive site preparation process includes custom blending compost and soils to promote proper soil microbiology. This nutrient-rich blend gives your new landscape a healthy, vigorous start, and gives us 100% confidence that your trees and shrubs will thrive.

Our creativity is informed by caretaking and practicality.

Astute design requires extensive knowledge of plant material and how each species, cultivar, and specimen perform in the Hamptons’ unique climate.

Knowledge built over many years of tending Long Island landscapes translates into a design aesthetic that’s creative yet sensitive to the Hamptons’ special environment while fulfilling your family’s lifestyle needs and wishes.

We welcome and appreciate the opportunity to work with your landscape architect. Mahoney also has in-house designers available for your renovation, revegetation, or entirely new landscape project.

Mahoney Associates is where landscape employees come to build careers.

Excellence only happens when the crews working on your project care enough to put in extra effort.

We foster caring by investing in the growth and well-being of our team with continuous learning, talent development, and professional education.

Our team has worked together for years, bringing synergy, excellent communication, and the highest standards to each project.
