Emergency

Tree or large limb is on the house, service drop, or driveway

Pro-first

Likely causes

  • Storm failure
  • Cracked union
  • Root plate failure

Homeowner-safe check

Stay away from downed wires and loaded limbs; do not cut tensioned wood yourself.

When to call

Call emergency tree service and the utility if any wire is involved.

Emergency

Tree is suddenly leaning or soil is heaving at the base

Pro-first

Likely causes

  • Root plate failure
  • Saturated soil
  • Wind-thrown structural instability

Homeowner-safe check

Keep people, vehicles, and pets outside the fall zone.

When to call

Call an ISA arborist immediately for risk assessment and removal/mitigation.

Call soon

Dead branches hang over roof, sidewalk, or play area

Pro-first

Likely causes

  • Deadwood
  • Disease
  • Storm damage not yet shed

Homeowner-safe check

Do not stand under dead limbs; binocular inspection from the ground is enough.

When to call

Call soon before wind or ice turns deadwood into impact damage.

Call soon

Cavities, mushrooms, or soft spots appear at trunk/base

DIY-safe basics

Likely causes

  • Internal decay
  • Root rot
  • Old wound compartmentalization failure

Homeowner-safe check

Photograph and avoid filling cavities with foam or concrete.

When to call

Call an arborist for sounding, risk rating, and preservation/removal options.

Routine

Leaves wilt, thin, or discolor in one section

DIY-safe basics

Likely causes

  • Vascular disease
  • Root damage
  • Drought or soil compaction

Homeowner-safe check

Water deeply at the dripline and avoid fertilizer until diagnosis.

When to call

Call routinely if decline progresses, high-value trees are involved, or pests are visible.

Call soon

Roots lift sidewalk, driveway, or foundation-adjacent flatwork

Pro-first

Likely causes

  • Shallow root growth
  • Species conflict with hardscape
  • Compacted soil

Homeowner-safe check

Do not cut structural roots without arborist review; it can destabilize the tree.

When to call

Call for root management, pruning, or removal plan before concrete replacement.

Routine

Stump resprouts or attracts insects

DIY-safe basics

Likely causes

  • Live root system
  • Incomplete grind
  • Moist decaying wood

Homeowner-safe check

Cut sprouts at grade and keep mulch away from siding/foundation.

When to call

Call routinely for regrinding or herbicide treatment if roots keep sprouting.

Call soon

Branches rub roof, siding, or service mast

Pro-first

Likely causes

  • Canopy too close to structure
  • Improper past pruning
  • Wind movement

Homeowner-safe check

Avoid ladder/chainsaw combinations; keep clear of service conductors.

When to call

Call soon for clearance pruning before abrasion creates leaks or electrical hazards.

Routine

Quote lacks workers' comp or rigging plan

DIY-safe basics

Likely causes

  • Uninsured climber
  • Unsafe removal approach
  • Subcontracted crew without oversight

Homeowner-safe check

Ask for certificates directly from the carrier and a written drop/rigging plan.

When to call

Call another tree company if they cannot document workers' comp and liability coverage.

Emergency

Tree is near utility primary lines

Pro-first

Likely causes

  • Utility clearance zone
  • Energized conductor hazard
  • Storm-prone limb over line

Homeowner-safe check

Do not prune within utility clearance distances; even non-contact can arc.

When to call

Call the utility first, then a line-clearance-qualified tree contractor if needed.

Maintenance schedule

Seasonal tasks

Spring

  • After leaf-out, compare canopy density by branch and mark sudden dieback, bark splits, or fungal shelves near the root flare.

Summer

  • During drought, water valuable young trees deeply at the dripline and keep mulch off the trunk bark.

Fall

  • Before storm season, look for limbs over roofs, service drops, parking areas, and play spaces without standing under them.

Winter

  • In winter dormancy, schedule structural pruning for appropriate species and avoid topping cuts that create weak sprouts.

Interval tasks

Monthly

  • Monthly, photograph trunk lean, soil heave, codominant stems, and cracks after wind so changes are obvious.

Annual

  • Yearly, have high-value or high-risk trees reviewed by an ISA-certified arborist, especially after construction near roots.

Every few years

  • Every few years, reassess clearance from rooflines, chimneys, solar arrays, fences, and buried utilities before removal becomes urgent.

Cost components

Labor

Labor depends on climbing/rigging complexity, crane or lift needs, cleanup volume, chip/wood handling, stump work, traffic control, and crew insurance burden. Pricing turns on climbing difficulty, rigging time, crane access, drop-zone protection, disposal volume, and utility clearance.

Materials

Separate ropes, rigging hardware, mats, crane time, stump teeth, chip trucks, plant-health products, and replacement trees from the base allowance of materials are lighter than labor but include rigging gear wear, fuel, saws, mats, stump teeth, plant-health products, and disposal fees.

Permits and inspections

Permits are most likely around street trees, protected species, utility corridors, right-of-way removals, and large stumps. Confirm submittals and final signoff locally.

Broad range discipline

Read cost bands around pruning, technical removal, crane work, stump grinding, and plant-health care. Small pruning is modest; removals near structures or wires are high-risk and high-cost; crane removals, large dead trees, and emergency storm work are major jobs.

What moves price

Pushes price up

  • Tree over structure or utility; added cost is usually tied to climbing difficulty
  • Dead/brittle wood; added cost is usually tied to rigging time
  • Crane/lift/traffic control; added cost is usually tied to crane access
  • Emergency storm response; added cost is usually tied to drop-zone protection

Can reduce price

  • Open drop zone; lower pricing is likelier when ropes is clearly defined
  • Homeowner keeps firewood; lower pricing is likelier when rigging hardware is clearly defined
  • Bundled pruning/removal; lower pricing is likelier when mats is clearly defined
  • Off-season scheduling; lower pricing is likelier when crane time is clearly defined

Hiring red flags

  • Risk around climbing or crane work priced without workers comp proof is waved away instead of priced and documented.
  • No clear method is given for verifying drop zone, rigging points, and utility clearance.
  • Savings rely on bypassing stump depth, chip removal, or log disposal plus the records that prove the work.
  • Coverage language skips damage to lawn, irrigation, roof, fence, and nearby plantings, including callback responsibility.
  • No workers' comp certificate for climbers.
  • Door-to-door storm crew with no local address or arborist credential.
  • Offers topping as routine tree care.
  • Will work near utility primary lines without line-clearance qualification.

Contract checklist

  • Exact trees, limbs, pruning standard, removal method, stump diameter, and grind depth with brands, sizes, locations, and exclusions.
  • ISA arborist involvement, utility notification, crane access, traffic control, and drop-zone protection before work starts, including who schedules inspections.
  • Debris handling for chips, logs, rakings, sawdust, and hidden metal in trunks or fences for access, protection, cleanup, and disposal.
  • Protection for lawns, irrigation heads, hardscape, roofs, service masts, and neighboring property as unit pricing or written allowances.
  • Insurance certificates, workers comp, weather limits, emergency priority, and cleanup acceptance; closeout requires photos, manuals, registrations, and lien releases.
  • Tree(s) identified, exact pruning/removal scope, ANSI-style cuts, and cleanup level.
  • Rigging/crane/lift plan, property protection, traffic/neighbor coordination.
  • Stump grinding depth, debris/wood/chip handling, and lawn repair responsibility.
  • Workers' comp and liability certificates from carrier, not just a PDF copy.
  • Utility, municipal, HOA, or street-tree approvals where relevant.

Warranty norms

Tree work warranties are usually narrow because living trees respond to weather, pests, soil, and prior cuts. Pruning workmanship may be corrected, and plant-health treatments may include follow-up visits, but survival promises should name species, watering duties, diagnosis limits, and storm exclusions.
