Remove what's dangerous, protect what's worth keeping

Sometimes. Many cities and HOAs regulate protected, heritage, or large-diameter trees — and some street or right-of-way trees — even when they stand on private property, and removing one without approval can bring a fine or a replanting requirement. Rules vary widely by municipality, so it is worth checking with your local planning or urban-forestry office, or asking the arborist, before scheduling a removal. A reputable company will usually know the local ordinances or help you confirm them.

It usually comes down to three things: the tree's health, its structure, and its target — what it could hit if it or a large limb failed. A tree with a modest, treatable problem and nothing important beneath it is often worth saving through pruning or treatment. One that is dead, has major structural defects like a split trunk or extensive decay, or leans over the house is typically safer removed. A certified arborist can weigh those factors honestly rather than defaulting to removal.

Topping — cutting main limbs back to stubs to reduce height — is one of the most damaging things you can do to a tree. It removes so much canopy that the tree is stressed and starved, the flat cuts rarely seal and often invite decay, and the tree tends to respond with dense, weakly attached water sprouts that are more likely to break in the next storm than the limbs they replaced. Proper crown reduction, which cuts back to sound lateral branches, controls size without that damage.

Treat it as an emergency when a tree or large limb has already fallen on a structure or is leaning on power lines, when a major limb is cracked and hanging, or when a tree has partially uprooted and could come down on something. Those situations involve stored tension and unpredictable loads and should be handled by a trained crew, not a homeowner with a chainsaw. Cosmetic damage, minor deadwood, or a lean that has been stable for years can generally wait for a scheduled visit.

Tree work is genuinely dangerous, and if an uninsured crew is hurt on your property or drops a limb on your house, the liability can land on you. Confirm the company carries both general liability and workers-compensation insurance, and ask for a current certificate. ISA (International Society of Arboriculture) certification signals the arborist has been trained and tested on tree biology, safety, and proper pruning — the judgment that separates real tree care from simply cutting things down.
