Landscape design and installation covers the planning and building side of outdoor space: grading, planting beds, sod or artificial turf, trees and shrubs, mulch and edging, walkways, retaining walls, and sometimes the layout work that ties into patios, fencing, or irrigation done by other trades. In Markham, this often means dealing with clay-heavy soil, drainage runoff from newer subdivisions, and HOA or municipal rules on front yard plantings, so a company that knows the area's soil and bylaws has a real advantage over one that doesn't.
We're tracking 19 landscape design and installation businesses serving Markham. Some are design-build firms that handle everything from a 3D rendering to the final planting. Others are smaller crews better suited to a straightforward yard refresh or sod replacement. Before hiring, ask to see photos of completed jobs in your neighborhood, get a written scope that separates design fees from installation costs, and confirm who's responsible for plant warranties if something dies in the first season.
Our scores weigh how a company communicates through quoting and scheduling, the consistency of its finished work across multiple jobs, and how it handles problems like drainage issues or plant failure after the crew leaves. That's laid out in full on our methodology page. For the full ranked breakdown of all 19 companies, see our best landscape design and installation companies in Markham guide.
