What are the signs a tree is about to fall?

The urgent ones - treat any of these as a same-week call: A new or increasing lean , especially after rain - compare against old photos if unsure Soil heaving, mounding, or cracking at the base opposite the lean: the root plate is moving Exposed or freshly lifted roots on one side Cracks or splits where the trunk forks or where major limbs attach Mushrooms or conks at the base - decay in the anchoring wood Recent trenching or construction through the root zone within the last few years Context multiplies risk: saturated winter soil plus wind is when compromised trees actually go, and a tree that "has always leaned" is different from one that leans more this month. If you see heaving soil or a fresh lean, keep people and cars out from under it and call (650) 355-1277 - we assess the same day where possible and remove genuinely dangerous trees on an emergency basis.
