Safe, controlled removal of hazardous, diseased, dead, or structurally compromised trees. We use advanced rigging and sectional dismantling to protect your home, fence, and landscaping. Call or text (720) 807-2785 for same-day emergency removal.
Get Removal Estimate →Crown cleaning, thinning, raising, and structural pruning following ANSI A300 industry standards. Proper trimming extends tree life, increases sunlight for your lawn, and prevents disease. Seasonal trimming — spring/summer for health, fall/winter for storm prep.
Schedule Trimming →Stumps are eyesores and hazards — they attract termites, carpenter ants, and fungi. We grind stumps 6–12 inches below grade, destroying the root system to prevent regrowth. Mulch stays on-site for landscaping, or we haul it away. Typical cost: $100–$400 per stump.
Get Stump Quote →Colorado weather is unpredictable — ice storms, high winds, and heavy snow can bring trees down fast. If a tree or limb is threatening your home, family, vehicle, or driveway, call (720) 807-2785 any time. We dispatch as quickly as possible, often same day.
Emergency Line →EAB has killed billions of ash trees across North America and Colorado infestations are spreading fast. Early action is the difference between an affordable treatment and a costly removal. We offer EAB inspection, systemic insecticide treatment, and removal. Under 30% canopy loss = treatable.
Free EAB Inspection →Our ISA member arborists provide specialized expertise: health assessments, disease diagnosis, iron chlorosis treatment, deep root fertilization, and personalized care plans. We follow ANSI A300 standards and maintain active ISA membership.
Schedule Arborist Visit →Protect vulnerable trees with professional cabling and bracing. We install support systems that reinforce weak limbs and co-dominant stems, helping trees withstand Chinook winds and heavy snow loads — reducing the risk of breakage without removal.
Learn About Cabling →Upgrade your landscape with professional tree planting. We help you choose the right species for Colorado Front Range conditions — accounting for alkaline clay soils, late spring freezes, and drought — then plant in the ideal location for long-term growth, shade, and curb appeal.
Plan Your Planting →Get your property ready to build — or restore it quickly after storm damage. We safely clear downed limbs, trees, brush, and debris, leaving a clean usable site ready for construction or landscaping while following applicable local regulations.
Get Clearing Quote →Complete commercial tree care for businesses and properties across Denver. From routine maintenance and pruning to hazard mitigation and emergency response, our team keeps your landscape safe, professional-looking, and well-maintained year-round.
Commercial Inquiry →Keep your property safe, healthy, and beautiful. From routine pruning and maintenance to emergency response and tree removal, we improve the health, appearance, and safety of your residential outdoor space. We don’t just cut trees — we protect your home and property value.
Residential Quote →Stock up with clean, reliable firewood that burns hot and lights easily. We also deliver premium mulch derived from our tree care work. Available across the Denver Metro Area — ask about delivery pricing when you call.
Order Firewood →Not sure whether a tree is dying or simply stressed? An ISA Member Arborist inspects the canopy, trunk, and root collar, identifies what is actually wrong, and gives you a written plan — including an honest answer on whether the tree is worth saving.
Book an Assessment →Denver soils are compacted and alkaline, which starves tree roots of what they need. We inject nutrients directly into the root zone to correct deficiencies and rebuild vigor in stressed or declining trees.
See Fertilization Details →Foothills and wildland-urban interface properties need canopy spacing, ladder-fuel removal, and zone-based clearing to slow fire spread. We build defensible space to recognized zone standards without stripping a property bare.
Plan Defensible Space →We don’t just cut trees — we help protect your home, safety, and property value with professional, risk-aware tree work.

Direct answers from our ISA member arborists on the questions Denver homeowners ask most.
Small trees under 30 ft typically run $300–$500. Medium trees (30–60 ft) average $500–$900. Large trees or trees near structures, power lines, or with tight access can exceed $2,500. We provide free on-site estimates — you know the price before any work starts.
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 than full structural pruning. We provide clear written quotes — no surprises, no hidden fees.
Trees are dormant, wounds heal rapidly as spring growth starts, and bark beetle and fungal pressure is lowest. Important: Never trim elm trees between April and September — this is the primary Dutch Elm Disease transmission window. Dead, hazardous, or storm-damaged branches should be removed immediately regardless of season.
Key exceptions: right-of-way trees (between sidewalk and street) are city-owned and require a permit from Denver Parks & Recreation. HOA restrictions may prohibit removal on your lot — check your HOA rules. Heritage trees in certain neighborhoods may have local protections. Our arborists will advise you during the free estimate visit.
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; and limbs contacting power lines. Call (720) 807-2785 any time.
EAB is spreading rapidly across Colorado’s Front Range. 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 (720) 807-2785 for a free EAB inspection.
Before hiring any tree service, ask for proof of ISA membership, a certificate of insurance (COI), and workers’ comp proof. Tree Service Denver LLC is ISA-member, carries $1M liability insurance, and holds a 5.0/5 rating across 164 Google reviews.
Crown reduction trimming (reducing canopy volume 20–30%) dramatically lowers wind load without harming tree health. Highest-risk species: Siberian elm, Bradford pear, box elder, silver maple. Annual inspection before spring wind season is good practice for any large tree near a structure.
The most common first steps: a free estimate for a known project; the warning signs guide when a tree just seems off; the cost guide for budgeting; the EAB page if you own an ash tree (in this metro, that’s urgent reading); your city’s page via service areas for local specifics; and the emergency line when something is down, hanging, or leaning right now. Wherever you enter, it ends the same way: a professional assessment, a written number, and work that matches both.
Our ISA member arborists walk your property, assess your trees, and give you a clear written quote — no surprises. Serving the entire Denver Metro Area.
