Overview
Trees can suffer from pests, disease, drought and soil problems. An arborist can diagnose issues and recommend care.
Early detection often gives more treatment options.
The usual process
- Inspect the tree. Look at leaves, bark and roots.
- Diagnose. Testing may be needed.
- Treat. Options include pruning, treatment or watering.
- Note the tree and the concern. Species if known, height and what it's near help providers plan the work.
- Expect an assessment. Arborists look at structure, health and hazards like power lines before quoting.
- Ask about cleanup. Chipping, hauling and stump work are often priced separately.
What affects the outcome
- Insurance is essential. Tree work is risky, so confirm liability and workers' comp coverage.
- Drought stress is common. Colorado's dry climate stresses trees.
- Not every tree can be saved. Removal may be safer.
- Timing matters. Some species are best pruned in certain seasons to reduce disease and stress.
- Some pests are regional. Emerald ash borer affects ash trees in some areas.
- Power lines need specialists. Trees near utility lines may require utility coordination.
Before you send an inquiry
- Any HOA, landlord or property manager rules that apply.
- A short description of the job and where it is on the property.
- Your timeline, and whether anything is urgent.
- Photos, if you have them; they help a provider understand the job faster.
- Your address or nearest cross streets so the request reaches someone local.
Red flags to watch for
- Door-to-door offers right after a storm with no local track record.
- No local address or references you can check.
- Suggesting you skip a required permit to save money.
- No written estimate, or an estimate with vague scope.
- Pressure to sign or pay the same day.
Questions worth asking
- Do you carry liability and workers' compensation insurance?
- Is stump grinding included or separate?
- Is an ISA-certified arborist involved in the assessment?
- Do any city permits apply to this tree?
- How will you protect the lawn, driveway and structures?
- Is cleanup, chipping and haul-away included?
