Landscape design and installation covers the planning and build-out of a property's outdoor space: grading, planting beds, sod and seed, mulch, trees and shrubs, hardscape elements like patios and retaining walls, drainage work, irrigation lines, and lighting. Some Stamford outfits handle the full job from design sketch to final planting; others specialize in one piece, like a drainage fix or a stone patio, and bring in a designer or subcontractor for the rest. We've cataloged 58 businesses in this category, ranging from small crews doing residential yards in Springdale and Belltown to larger firms that also take on commercial and HOA properties.
Before hiring, ask for a written scope with plant lists, material specs, and a start-to-finish timeline, not just a lump-sum number. Get proof of insurance and a clear answer on who pulls permits if the job involves grading, retaining walls over a certain height, or drainage tied into town storm systems. Ask to see a project that's now a few years old, not just fresh install photos, since that tells you how the plantings and hardscape actually held up through Connecticut winters.
Our scoring weighs review consistency, how a company handles complaints and follow-up, and the range and complexity of work they've actually completed, not just marketing claims.
