Whether you are planning a full yard redesign, a new patio, or a smarter irrigation setup, the team at AGT Landscape & Design is ready to help. We serve homeowners, builders, HOA communities, and commercial property managers across Boulder, Larimer, and Weld Counties. From our Longmont and Berthoud base, we bring hands-on Front Range expertise to every project in communities like Erie, Lafayette, Fort Collins, Loveland, Niwot, Broomfield, and beyond. Reach out today and let us walk you through what a locally owned, full-service Design-Build-Maintain approach can do for your property.

AGT Landscape & Design is owner-operated by Alex Tanner, a Northern Colorado specialist who understands the clay-heavy soils, intense high-altitude UV exposure, and 70 to 90 annual freeze-thaw cycles that make this region uniquely demanding. Every project we take on, from precision laser-graded drainage work to HOA-compliant hardscape installations, is backed by a 2-year warranty on hardscape and irrigation, double the industry standard. Our crews carry OSHA 10 cards, hold Colorado Pesticide-Applicator licenses, and operate under $5 million in general liability coverage. When you connect with us, you are getting a single point of accountability from the first site discovery call all the way through ongoing seasonal maintenance. We serve Boulder, Longmont, Erie, Lafayette, Louisville, Superior, Lyons, Loveland, Fort Collins, Windsor, Johnstown, Firestone, Niwot, and Broomfield. We design it, we build it, and we maintain it.
