Spring and summer
After severe weather, observe from a safe distance for broken limbs and changes in tree condition. Arrange an assessment when a concern persists.
Autumn and winter
Review branches near structures and maintain clear access before storms. Utility-adjacent work requires utility coordination, not do-it-yourself trimming.

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.
