Emergency Tree Service in Oak Brook, IL

Storm Damage in Oak Brook

DuPage County averages 24 significant storm events per year, including 18 high-wind events. Emergency tree service is not a matter of if, but when.

What to Do Right Now

• Stay away - keep everyone out of the fall zone. If a tree is leaning on a power line, call the utility company first, not a tree service.
• Document the damage - take photos from a safe distance before anything is touched. Your insurance company will want these.
• Don't DIY - storm-damaged trees are under tension. Cutting the wrong branch releases stored energy and can kill you. This is not a chainsaw-on-the-weekend job.
• Call a certified arborist - not just "a guy with a truck." Storm chasers flood into areas after major storms, do bad work, and disappear. ISA certification matters more after a storm than any other time.

Emergency vs Regular Pricing

Expect to pay 50-100% more for emergency response compared to scheduled work. In Oak Brook, that means emergency tree removal typically runs $2,631 to $11,508. After major storms, demand spikes and prices go higher. If you can safely wait 48-72 hours, the "emergency" premium drops significantly.

Active Tree Threats in DuPage County

Emerald Ash Borer (EAB) critical

Affects: All ash species (Fraxinus) - green, white, black, blue ash

Metallic green beetle native to Asia. Larvae feed under bark, cutting off water and nutrient transport. Tree dies within 2-5 years of infestation. Has killed hundreds of millions of ash trees in North America since 2002.

What to do: Remove dead standing ash trees immediately - they become brittle hazards within 1-2 years. Preventive trunk injection (emamectin benzoate) can save high-value ash but requires biannual treatment.

Spotted Lanternfly high

Affects: Tree of Heaven (primary host), but feeds on 70+ species including maples, oaks, walnut, willow, birch, grape

Showy planthopper from Asia. Feeds on sap, excretes honeydew that promotes sooty mold. Doesn't usually kill trees directly but weakens them and creates a mess. Major agricultural pest on grapes and orchards.

What to do: Destroy egg masses (gray mud-like patches on any flat surface) October-June. Remove Tree of Heaven from property to eliminate breeding host. Report sightings to state agriculture department.

Oak Wilt high

Affects: Red oak group (red, pin, scarlet, black - usually fatal). White oak group (white, bur, swamp white - slower, sometimes survivable).

Fungal disease (Ceratocystis fagacearum) that clogs water-conducting vessels. Red oaks can die within weeks. Spreads through connected root systems between nearby oaks and via beetles attracted to fresh wounds.

What to do: NEVER prune oaks between April and October - beetles carry the fungus to fresh cuts. If an oak shows sudden wilting/browning, get a certified arborist assessment immediately. Root barriers can prevent spread between adjacent trees.

What 1960s-1980s-Era Trees Need in 2026

Common Issues

• **Green Ash death** - if your home was built in the 1970s and has a large shade tree in front, there's a good chance it's a green ash. These are now being killed by Emerald Ash Borer across the eastern US. Dead ash become brittle hazards within 1-2 years.
• **Dogwood decline** - dogwood anthracnose (Discula destructiva) killed millions of native flowering dogwoods starting in the 1980s. Surviving trees are often weakened.
• **Cherry tree aging** - flowering cherries planted in this era are at or past their 25-40 year lifespan. Bacterial canker and boring insects are common in aging specimens.

Recommended Actions

• Immediate assessment of any Green Ash - decide between treatment (expensive, ongoing) and removal (one-time, plan replacement)
• Replace dead or declining Dogwoods with disease-resistant Kousa Dogwood or native alternatives
• Evaluate Leyland Cypress hedges - thin or replace with smaller alternatives if they're overwhelming the property
