Our professionally trained crew handles every job with precision so your property is left in better shape than we found it.
You'll know exactly what's being done, why it's needed, and what it costs before any work begins.
Most tree problems don't show up overnight. Tree care Montreal homeowners rely on is about catching issues early before they become expensive problems. NASO Service offers full-site assessments that evaluate the structural health of every tree on your property, identify early signs of disease or decay, and recommend the right course of action based on what each tree actually needs. We'll never push for removal if pruning or treatment is the better call. Our goal is to keep your trees healthy, safe, and standing for as long as possible.

Frequently Asked Questions
We respond in under 10 hours. If you reach out during business hours, expect to hear back the same day. From there, we'll collect a few details and schedule a free in-person assessment at a time that works for you.
If the trunk measures over 10 centimetres in diameter at 1.3 metres from the ground, the City of Montreal requires a permit before removal. Permits are granted when the tree is dead, diseased, structurally unsafe, or poses a direct hazard. We can walk you through the application process if needed.
Yes, always. After your in-person assessment, we'll send a detailed written proposal that breaks down the scope of work and pricing line by line. Nothing starts until you've reviewed it, asked your questions, and given us the green light.
Everything gets removed before we leave. Branches and wood are either chipped on-site or loaded into our trucks and hauled away. We do a full walk-through with you at the end to make sure the job site is completely clean.
Not necessarily. A crack doesn't always mean removal is needed right away. The outcome depends on the depth of the crack, where it sits on the tree, and how far the decay has progressed. Left untreated, a crack can lead to structural instability and eventual removal. But with the right care and proper pruning, you can significantly extend the tree's lifespan and avoid that outcome. The safest step is having one of our trained arborists take a look and give you an honest answer.
