A hollow tree isn’t automatically an emergency removal, but it needs a real structural assessment. Some hollow trees are stable for years; others are close to failure. The difference comes down to how much sound wood remains around the hollow, not the hollow itself.
Why “Hollow” Doesn’t Automatically Mean “Coming Down”
Trees can develop significant internal decay and still stand safely for a long time, because the outer, living layer of wood does most of the structural work — a hollow core doesn’t necessarily mean the tree is about to fail. What matters is the ratio of sound wall thickness to the tree’s diameter, along with the size of any external cavity opening, root condition, and how exposed the tree is to wind. A small hollow with thick surrounding wood is a very different situation than a large cavity with a thin shell.
What We Check
- The size and location of any visible cavity or opening
- Sound wall thickness around the hollow, checked at multiple points
- Root condition and base stability, since hollow trunks and root decay often go together
- Wind exposure and what’s nearby if the tree does fail — house, driveway, power line, open yard
Signs a Hollow Tree Is a Higher-Risk Situation
A large external cavity opening, especially one facing the prevailing wind direction, mushroom or fungal growth at the base, or a hollow combined with a lean are all signs that push a hollow tree from “monitor” toward “remove.” We’ll tell you plainly which category your tree falls into.
Hollow Tree Removal Cost
Hollow tree removal typically runs $500 to $3,000. Structurally compromised hollow trees near a house or power line often require more careful sectional removal, which affects price. If monitoring is the right call instead of removal, that assessment is free.
Hollow Tree FAQ
Can a hollow tree be saved?
If the surrounding wood is still substantial and the tree isn’t leaning or root-compromised, many hollow trees can be safely monitored rather than removed. We’ll be direct about which situation you’re in.
How can I tell if my tree is hollow?
Visible cavities, holes from woodpeckers or old wounds, or a hollow sound when tapped are signs worth having checked. Some hollows aren’t visible from outside and only show up on closer inspection.
