It's the question we get asked more than any other on a first visit: does this tree actually need to come down, or can it be saved? The honest answer is that most trees we look at don't need removal — but the ones that do usually show their hand if you know what to read.
The clear-cut cases
Some trees remove themselves from the "maybe" column the moment we walk up. A tree should generally come down when it is:
- Dead or mostly dead — no leaf-out in spring, brittle branches, bark sloughing off in sheets.
- Severely diseased — advanced Dutch elm, established cankers, or decay that has hollowed the trunk.
- Structurally compromised — a major crack through the trunk, a split union, or a large cavity at a load-bearing point.
- Leaning suddenly — a fresh lean with heaved or cracked soil on the high side means the root plate is failing. That's an emergency, not a wait-and-see.
- Damaging a structure — roots into a foundation, limbs grinding a roof, or a trunk that has outgrown its spot against the house.
The warning signs worth a closer look
Other trees are decisions, not certainties. Large dead limbs high in the canopy, extensive decay at the base, visible root damage from a recent excavation, and shelf-like fungal growth (conks) around the root flare are all signals that something is wrong below the surface. None of them automatically mean removal — but together they tell a story, and a mushroom ring at the base of a mature maple is worth a phone call.
A tree that looks healthy from the curb can be unsound at the base, and a tree that looks rough can have decades left. The base and the union tell the truth.
Why an assessment beats a guess
This is exactly where an ISA-Certified Arborist earns their keep. We sound the trunk for hollow sections, read the root flare, check the lean against the soil, and weigh what's above the tree — your house, the driveway, the neighbour's fence, the hydro line. Nine times out of ten that assessment lands on pruning, cabling, or simply monitoring rather than removal. Across Kitchener, Waterloo, Cambridge and Guelph we'd far rather keep a sound tree standing than take down one that had good years left.
