Tree services cover the work most homeowners either can't or shouldn't tackle themselves: pruning and crown thinning, removal of dead or hazardous trees, stump grinding, storm cleanup, and cabling or bracing for trees with structural weaknesses. In Markham, this also includes navigating the city's tree preservation bylaw, which requires a permit before removing or injuring trees over a certain size on private property. A good tree company handles that paperwork as part of the job, not as an afterthought.
What to look for before hiring
Markham has 15 tree services listed in this category, ranging from small two-person crews doing pruning and small removals to larger outfits with bucket trucks and crane capability for big jobs. Before hiring, ask about insurance (liability and WSIB coverage for the crew), whether they're familiar with Markham's permit requirements, and how they handle debris and stump disposal. Get a written quote that specifies the scope: full removal versus just the canopy, whether stump grinding is included, and who's responsible for cleanup. Arborists with ISA certification generally give more reliable diagnoses of disease, pest damage, or structural risk than a crew that just cuts on request.
How we score them
Our rankings weigh review consistency, responsiveness, and how a company handles the less glamorous parts of the job: cleanup, communication, and follow-through on quotes. Full details on how we calculate scores are on our methodology page. For a side-by-side comparison of Markham's top-rated crews, see our best landscapers in Markham guide.
