Tree removal in Thornhill typically costs $300 to $2,000 for a small to medium tree under 30 feet. Large trees over 60 feet can cost $2,000 to $6,000 or more depending on accessibility, proximity to structures, and whether a crane is required. Stump grinding is usually an additional $100 to $400 per stump. Emergency removal after a storm typically carries a premium.
Late winter to early spring, before trees leaf out, is the optimal time for most pruning in Thornhill. Trees are dormant, making it easier to see the structure and minimizing stress to the tree. Summer pruning is fine for light shaping or removing dead branches. Avoid heavy pruning in fall as wounds heal slowly going into winter. Fruit trees have more specific timing requirements.
Many municipalities in Thornhill regulate the removal of trees above a certain trunk diameter, particularly on front yards, environmental protection zones, or heritage tree designations. Some cities require a permit for any removal of healthy trees while others are less restrictive. Check with your local municipality before removing any significant tree to avoid fines.
Tree service is one of the highest-risk trades. Always confirm that the company carries general liability insurance with a minimum of $2 million in coverage and WCB/WSIB workers compensation for all crew members. Ask for proof of insurance certificates before work begins. Working near structures, power lines, or in confined spaces creates significant liability that should be covered.
Ask whether any crew members hold a Certified Arborist credential from the International Society of Arboriculture (ISA), which is the industry standard for tree care knowledge. Request a written quote specifying exactly which trees or branches are to be removed or trimmed, what becomes of the debris (chipping, removal, or leaving on site), and whether stump grinding is included.
