Pricing & Costs
1 How much does tree removal cost in Denver, CO?
| Tree Size | Typical Range |
|---|---|
| Small (under 30 ft) | $300–$500 |
| Medium (30–60 ft) | $500–$900 |
| Large (60 ft+) or near structures | $1,000–$2,500+ |
Factors that increase cost: tight yard access, proximity to power lines, a leaning trunk, or hauling wood vs. chipping on-site. We provide free, no-obligation estimates — you know the price before any work starts.
📞 Call Now2 How much does tree trimming cost in Denver?
- Small ornamental trees: $150–$300
- Medium shade trees (30–50 ft): $300–$500
- Large trees (50 ft+): $600–$1,000+
Crown cleaning (removing dead wood) is generally less expensive than full structural pruning. We walk the property with you and give a clear written quote before starting — no surprises, no hidden fees.
📞 Call Now3 Does homeowner’s insurance cover tree removal in Denver?
Most policies have a $500–$1,000 per tree limit for removal after a covered event.
Policies generally do NOT cover:
- Removing a standing hazard tree that hasn’t fallen yet
- A tree that fell in your yard but missed structures
- Routine removal for aesthetic or preventive reasons
Always verify with your insurer before assuming coverage. We provide detailed written estimates and can document damage to support your claim.
4 What is stump grinding and should I do it after tree removal?
Stump grinding uses a rotating cutting wheel to reduce the stump and surface roots to wood chips below ground level. Leftover stumps:
- Attract termites, carpenter ants, and wood-decaying fungi
- Create tripping hazards
- Continue producing regrowth shoots for years
- Block new planting, lawn seeding, or landscaping
Grinding vs. pulling: Grinding preserves your lawn grade, leaves no large hole, and destroys the root system to prevent regrowth. The wood chip mulch left on-site can go into landscaping or be hauled away — your choice.
5 How much does stump grinding cost in Denver?
| Stump Size | Typical Range |
|---|---|
| Small (under 12 in diameter) | $100–$175 |
| Medium (12–24 in) | $175–$280 |
| Large (24 in+) | $280–$400+ |
Multiple stumps on the same visit are usually discounted. Ask about bundling stump grinding with tree removal for the best pricing.
Timing & Scheduling
6 What affects the final price of tree removal the most?
- Tree height and trunk diameter — larger trees require more labor and time
- Site accessibility — open backyard vs. tight access between structures
- Proximity to power lines or buildings — specialized rigging required
- Stump grinding — usually quoted separately
- Debris disposal preference — chip on-site vs. full haul-away
- Emergency/after-hours premium — storm response calls carry a premium
The only way to know your exact cost is a free on-site estimate — call us and we’ll walk the property with you.
7 When is the best time to trim trees in Colorado?
- Late winter (Feb–early March): Best for oaks, maples, cottonwoods, ashes — trees are dormant, wounds heal rapidly as spring growth starts, bark beetle and fungal pressure is lowest
- Spring (April–May): Good for fruit trees and ornamentals after the last freeze
- Summer: Possible but increases disease and insect risk — limit to dead wood removal only
- Fall: Avoid heavy pruning — fresh cuts can’t seal before frost
Exception: Dead, hazardous, or storm-damaged branches should be removed immediately regardless of season.
8 How long does tree removal take?
| Scenario | Typical Time |
|---|---|
| Small tree in an open yard | 1–2 hours |
| Medium tree with moderate access | 3–4 hours |
| Large tree near home, fence, or power lines | 5–8+ hours (specialized rigging) |
We haul away all debris and leave the property clean before we leave. Same-day emergency response is available — call or text (720) 807-2785 any time.
9 How quickly can you respond to an emergency tree situation in Denver?
For active hazards — tree on a structure, hanging limbs over walkways, uprooted tree blocking access — call (720) 807-2785 immediately. We prioritize emergency calls and dispatch as fast as possible, often same day.
For non-emergency estimates, we typically schedule within 1–2 business days.

10 How do I know if my tree needs to be removed or just trimmed?
Signs a tree likely needs removal:
- More than 50% of the canopy is dead or dying
- Large cracks, cavities, or hollow sections in the trunk
- Significant lean — especially sudden lean after a storm
- Roots are lifting, rotting, or showing fungal growth at the base
- Advanced disease with no viable treatment (e.g., late-stage EAB in ash trees)
Signs a tree can be saved with trimming:
- Structurally sound trunk with dead or crossing branches
- Overgrown canopy crossing power lines or the roofline
- Crown thinning or raising needed for clearance
Our ISA member arborists provide a free on-site assessment and give you an honest recommendation — we’ll never push removal when trimming is the right answer.
📞 Call Now11 How do I know if my ash tree has Emerald Ash Borer (EAB)?
EAB is spreading rapidly across Colorado’s Front Range. Key warning signs:
- D-shaped exit holes (~1/8 inch wide) in the bark
- S-shaped galleries (winding tunnels) visible under loose or peeling bark
- Crown dieback starting at the top — branches die top-down
- Increased woodpecker activity — they feed on EAB larvae
- Epicormic sprouting — new shoots growing from the trunk base or major branches
Early-stage EAB (less than 30% canopy loss) can often be treated with systemic insecticides. Once more than 50% of the canopy is affected, removal is usually the only safe option. Don’t wait — EAB moves fast and a dead ash becomes a hazard tree quickly.
📞 Call Now12 What are the most common signs a tree is dying or hazardous in Denver?
Denver trees face stress from alkaline soils, late spring freezes, drought, and bark beetles. Watch for:
- Crown dieback: Dead branches at the top or scattered through the canopy
- Trunk damage: Cracks, cavities, bark sloughing off, or vertical seams
- Fungal growth: Mushrooms or shelf fungi at the base or on the trunk signal internal rot
- Root heaving: Soil lifting or roots becoming exposed near the base
- Sudden lean: A new or worsening lean is an immediate red flag — call for evaluation right away
- Bark beetle galleries: Fine sawdust or pitch tubes on pine and spruce bark
When in doubt, call for a free walk-through. Catching hazard trees early is almost always less expensive than storm damage cleanup.
13 Why are my tree’s leaves turning yellow in Denver? (Iron Chlorosis)
Denver’s alkaline soils (high pH) prevent certain trees from absorbing available iron, causing interveinal chlorosis — yellow leaves with green veins. Most affected species: pin oak, silver maple, river birch, sweet gum, and some fruit trees.
Treatment options:
- Soil acidification: Elemental sulfur or iron sulfate applied to the root zone lowers pH over time
- Trunk injection: Direct iron application bypasses the pH problem — faster results
- Foliar spray: Chelated iron spray — temporary but quick
Severe or long-standing chlorosis may require professional diagnosis to determine if treatment is still viable. Our ISA member arborists can assess and recommend the right approach.
Tree Health & Services
14 What is deep root fertilization and does my Denver tree need it?
Standard broadcast fertilizers spread on the surface of Denver’s clay soil rarely reach tree roots effectively. Deep root fertilization uses a probe to inject liquid nutrients 8–12 inches below grade directly into the root zone.
Most beneficial for:
- Trees showing slow growth, thin canopy, or off-color foliage
- Trees in compacted urban soils with limited organic matter
- Drought-stressed trees recovering from a hard summer
- Trees being treated for disease or pest pressure
We also offer deep root watering during drought periods — particularly valuable on Denver’s Front Range where summer dry spells can be extreme.
15 What is an ISA member arborist and why does it matter?
It matters because ISA member arborists:
- Follow ANSI A300 pruning standards — the industry gold standard
- Can accurately diagnose disease and structural problems instead of guessing
- Know how to prune without harming or killing trees
- Carry professional liability that protects you
- Must complete continuing education to maintain their certification
Many “tree guys” in Denver are unlicensed laborers. Always ask for ISA credentials before hiring — or just call us. Every arborist on our team is ISA-member.
16 What credentials should I verify before hiring any tree service in Denver?
- ISA Member Arborist credential — confirms training in tree biology, pruning, diagnosis, and safety
- General liability insurance: At least $1M — ask for a certificate of insurance (COI)
- Workers’ compensation: Protects you if a crew member is injured on your property
- Written estimate: Any reputable company provides a written quote before work starts — no verbal-only agreements
- References or reviews: Google reviews, Yelp, or BBB — look for consistent, detailed feedback
Tree Service Denver LLC is ISA-member, carries $1M liability insurance, and has a 5.0/5 rating across 164 Google reviews.
17 Is it safe to trim trees near power lines in Denver?
Trimming trees in contact with live power lines is one of the most common causes of electrocution and house fires in residential tree work. Do not attempt this yourself.
In Denver, Xcel Energy is responsible for trees in direct contact with high-voltage transmission lines and will trim or remove them for free if you report the hazard.
For trees growing near but not touching distribution lines on your property, our ISA member arborists are trained in utility line clearance pruning and follow ANSI A300 Part 7 standards for safe work near energized conductors.
18 Do I need a permit to remove a tree in Denver?
You can remove trees in your own yard without city approval in most situations. Key exceptions:
- Right-of-way trees (between sidewalk and street) are city-owned — requires a permit from Denver Parks & Recreation
- HOA restrictions may prohibit removal on your own lot — check your HOA rules before proceeding
- Heritage trees in certain neighborhoods may have local protections
Our arborists know Denver’s local regulations and can advise you on your specific situation during the free estimate visit.
Emergency Service
19 What types of tree pruning do you offer and which one does my tree need?
| Pruning Type | What It Does | Best For |
|---|---|---|
| Crown Cleaning | Removes dead, dying, diseased branches | All trees — basic health maintenance |
| Crown Thinning | Selectively removes branches to improve airflow and light | Dense canopies, wind load reduction |
| Crown Raising | Removes lower branches to clear sightlines or structures | Clearance over rooflines, driveways, walks |
| Structural Pruning | Reinforces proper branch structure while tree is young | Young trees 3–15 years old |
| Fruit Tree Pruning | Maximizes health, yield, and shape | Apple, cherry, peach, pear trees |
Our ISA member arborists assess each tree before recommending a pruning type — we follow ANSI A300 pruning standards on every job.
20 How do I prepare my property for a tree service appointment?
- Unlock gates so equipment can access the backyard
- Move vehicles out of the driveway if the tree is nearby
- Relocate outdoor furniture, potted plants, and fragile items near the work area
- Keep children and pets inside during the job
- Point out concerns to the crew lead when they arrive — a garden bed to protect, a fence line to watch, a sprinkler head location
Our zero-damage guarantee means we use specialized rigging to protect your roof, fence, and landscaping. We leave the property clean — all debris is hauled away or chipped before we go.
21 Do you offer emergency tree removal in Denver?
We respond to:
- Trees fallen on a home, garage, fence, or vehicle
- Storm-damaged trees with hanging or split limbs over structures
- Trees leaning toward buildings after high winds or saturated soil
- Blocked driveways or access roads from downed trees
- Limbs contacting or near power lines
Call (720) 807-2785 any time — we dispatch as quickly as possible and give you an honest assessment of urgency before any work begins.

22 What is tree cabling and bracing and when is it needed?
Cabling and bracing is used when a tree has:
- Co-dominant stems (two main trunks competing) with a weak attachment point
- Heavy, overextended limbs at risk of splitting under snow or wind load
- Previously damaged structure that needs support while healing
- High-value trees where removal would be a significant loss
Cabling doesn’t fix a structurally failing tree — it extends the safe life of trees that are otherwise healthy but have specific mechanical vulnerabilities. Our ISA member arborists assess whether cabling is appropriate or whether pruning or removal is the better long-term choice.
23 What trees are most common in Denver yards — and which have the most problems?
| Tree | Common Issues in Denver |
|---|---|
| Green / White Ash | Emerald Ash Borer — treat early or plan for removal |
| Cottonwood | Brittle limbs, massive size, surface root damage, cotton release |
| Siberian Elm | Fast growth, extremely brittle in wind and ice storms |
| Bur Oak | Very hardy — occasional iron chlorosis in alkaline soil |
| Blue Spruce | Cytospora canker, spider mites, Ips bark beetles |
| Ponderosa Pine | Bark beetle susceptibility — especially in drought-stressed trees |
| Bradford Pear | Structurally weak — splits at 20–25 years; not recommended for planting |
Denver’s alkaline clay soils, periodic drought, late spring hard freezes, and Chinook winds create a uniquely stressful environment. Annual inspection matters more here than in most U.S. cities.
24 How do Denver’s Chinook winds affect my trees — and what can I do?
Denver sits at the base of the Rocky Mountains and experiences downslope Chinook winds that routinely gust to 50–80+ mph. These winds are responsible for the majority of tree failures and structural damage calls we receive.
Highest-risk situations:
- Trees with a large, dense, unbalanced canopy acting as a wind sail
- Trees with shallow roots in clay-heavy or saturated soil
- Prior root disturbance from construction or compaction
- Brittle species: Siberian elm, Bradford pear, box elder, silver maple
What you can do: Crown reduction trimming (reducing canopy volume 20–30%) dramatically lowers wind load without harming tree health. Annual inspection before spring wind season is good practice for any large tree near a structure.
25 When is it too late to save an Emerald Ash Borer-infested tree in Denver?
EAB treatment works best before or in the very early stages of infestation. Here’s how to think about the timeline:
| Canopy Loss | Treatment Viability |
|---|---|
| Under 30% | High — systemic insecticide treatment usually very effective |
| 30–50% | Moderate — treatment may slow decline but prognosis is guarded |
| Over 50% | Low — removal is almost always the safer and more cost-effective choice |
A dead or structurally compromised ash tree becomes a hazard quickly — the wood deteriorates fast after death. If you have ash trees, call for a free EAB inspection now rather than waiting for visible symptoms.
📞 Call Now26 Is it true I should never trim elm trees in summer in Colorado?
Dutch Elm Disease (DED) is spread by elm bark beetles that are most active April through September. Fresh pruning cuts during this window attract beetles and can introduce the lethal fungal pathogen directly into the tree’s vascular system.
Safe elm pruning window in Colorado: October through March (when beetles are dormant).
If an elm limb breaks in summer due to storm damage, clean cuts are acceptable — the wound is unavoidable. But elective pruning should never be scheduled during the warm season. Denver’s urban elm canopy is a valued resource — this rule exists specifically to protect it.
