Choose the work first
Describe the tree, location, nearby structures, access constraints and whether it is on private or public land. A provider can then assess the work and explain its scope.
Check responsibility
Public trees, parkways, easements and utility corridors may involve the city or a utility. Confirm the responsible party before authorizing work.

BEFORE YOU DECIDE
Ask for a written scope.
Confirm what work is included, who handles debris, and whether permit or utility coordination applies. Compare provider credentials and availability directly.
