When a tree should come down
Removing a tree is permanent, so it's worth being sure. Many trees that look worrying can be made safer with pruning, cabling or treatment. Removal is usually the right choice when:
- The tree is dead or dying, with no live buds, peeling or missing bark, or widespread dieback in the canopy.
- The trunk or main limbs are seriously damaged, split, or hollow over a large portion of their diameter.
- The roots are failing, shown by fungal growth at the base, soil heaving on one side, or a new lean.
- The tree leans dangerously toward a house, driveway or power line, especially if the lean is new.
- It's the wrong tree in the wrong place, such as roots lifting a foundation or sewer line, or a tree growing into a structure.
- Disease or pests have damaged it beyond recovery, or it threatens nearby trees.
If you're unsure, ask an arborist for an assessment before deciding. A good one will tell you when a tree can be saved.
How removals are done
Small trees in open areas may be felled in one piece. Most trees near homes, fences and lines are taken down in sections: a climber or an aerial lift removes limbs and lowers them with ropes, then the trunk is cut in manageable pieces from the top down. Cranes are used for large trees over houses or where there's no room to lower pieces. The method affects price and timing; ask how the crew plans to bring your tree down and protect what's around it.
Trees near power lines
Never try to trim or remove a tree that touches or is close to an overhead power line. Electricity can travel through branches and equipment. Call your electric utility first. Utilities often handle clearing around their lines, and tree workers need specific training and qualifications to work near energized lines.
Permits and protected trees
Many cities and counties protect certain trees, such as large trees, heritage trees, street trees or specific native species. Removing a protected tree without a permit can bring fines and replacement requirements. Street trees in the planting strip between the sidewalk and street are often managed by the city. Before removing a large tree, check with your local planning or urban forestry department, or ask the contractor to confirm.
What a complete removal includes
1. An assessment of the tree, its surroundings and the removal method. 2. Any permit needed for protected or street trees. 3. Protection for lawns, driveways, fences and structures during the work. 4. Removal of the tree in sections or by felling, as appropriate. 5. Cleanup of branches and debris, chipped or hauled away. 6. Optional log removal or firewood cutting. 7. Optional stump grinding, which is often priced separately.
Ask what's included. "Removal" doesn't always include hauling the wood or grinding the stump.
Questions to ask
- Why do you recommend removal, and is there any way to save the tree?
- How will you take it down, and how will you protect my house and yard?
- Is a permit required, and who will get it?
- Is cleanup, wood removal and stump grinding included?
- Do you carry insurance for your crew and for property damage? Ask for proof.
Wood and debris
Ask what happens to the wood. Some homeowners keep logs for firewood or chips for mulch; others want everything hauled away. The answer affects the price, so settle it before work starts.
