Our specialty
Impossible cases are our everyday work.
A split trunk hanging over the roof, an ash tree condemned by the city, a tree wedged between two fences: when other companies walk away, we're the ones people call.
- Dangerous, dead or unstable trees — we step in where it's risky
- Tight access: narrow backyards, trees over buildings and power lines
- Piece-by-piece dismantling with rigging, bucket truck or crane
- Emerald ash borer removals, fully compliant with city bylaws

"A huge split maple was leaning right over our roof. The crew came the same evening to secure it, then dismantled everything piece by piece. Impressive precision."
"Honest price, fast work, and the yard was cleaner after they left than before they arrived. You can tell it's 30 years of experience. Highly recommended."

Common questions
You might be wondering…
How much does tree removal cost in Montreal?
Every tree is different: height, diameter, access, nearby obstacles. That's why we visit for free and hand you a firm, detailed price before any work starts. Call 514-983-9100 — the estimate costs nothing.
Do I need a permit to remove a tree?
In most Montreal boroughs and surrounding municipalities, yes. We know the local bylaws and guide you through the paperwork before work begins.
Do you really respond 24 hours a day?
Yes. Tree on a car, limb torn off by wind, trunk blocking a driveway: our emergency service runs 24/7, including weekends and holidays — even in winter.
Do you haul away the branches and wood?
Always. Branch chipping and complete yard cleanup are included in our quotes. On request, we can also leave the wood cut into logs for your fireplace.
