Longmont Tree Company looks after trees all over Longmont, from the big old shade trees along the alleys of Old Town and the Historic Eastside to younger plantings in Prospect, Clover Basin and Somerset Meadows. We take down trees that have died or turned dangerous, trim and prune the ones worth keeping, grind stumps, and clean up after the wet spring snowstorms that snap limbs across town.
Ash trees are a big part of tree work here. Emerald ash borer has been in Longmont since 2016, and untreated ash trees don't survive it. We'll tell you straight whether yours is worth treating or should come down before it turns brittle. Every job starts with a visit and a written price, and cleanup is always included. That heavy, wet snow on May 6, 2026 was rough on trees with their leaves already out. Across the Front Range, branches came down and trees took a beating. Snow piled on green leaves is a tough combination: those limbs can only hold so much.
Why trees? "I like working with my hands and being able to look back at the end of the day and see what I got done. A good shade tree means a lot around here. Helping somebody keep theirs healthy is satisfying work."

24/7 Emergency Tree Removal
When a tree comes down on a house, car or fence, our emergency line is answered around the clock. The first job is making the area safe: we take the weight off the roof, cut the tree away from the structure and clear a path so you can get in and out.
Tree Removal
Dead, dying, leaning or simply in the wrong place, we take trees down in sections and lower the heavy pieces with ropes so nothing lands on your house, fence or garden. Tight backyards and trees next to power lines get a plan before anyone climbs.
Tree Trimming and Pruning
Trimming keeps branches off the roof, away from the lines and out of the way of the mower. Pruning goes further and shapes the tree's structure so it stays strong as it grows. Both remove deadwood that could fall in the next storm.
Cabling and Bracing
A tree with a weak fork or a split starting at the trunk doesn't always have to come down. Steel cables or rods installed high in the canopy share the load between limbs and can buy a valuable tree many more years.
Stump Grinding
A grinder chews the stump and its main roots down below the soil line, usually 6 to 12 inches. The chips can fill the hole or be hauled away, and the spot can be topped with soil and seeded for grass. No digging up the yard and no waiting years for it to rot.
Tree Health and Disease Care
Thin leaves, dead branches at the top, odd holes in the bark or mushrooms at the base are all signs worth checking. We look at the tree, the soil and the roots, tell you what's going on and whether treatment is likely to work.
Commercial, HOA and Managed Properties
HOA common areas, apartment and office grounds, churches, schools and parking-lot islands. Property managers get one written plan covering every tree on the site, work scheduled early or in sections so lots and walkways stay open, and invoices that are simple to pass along to a board.
How Much Does Tree Service Cost in Longmont, CO?
These are typical ranges, not quotes. Height, trunk size, how close the tree is to buildings and whether a bucket truck or crane can reach it make the biggest difference. One published Longmont cost guide puts removing a medium tree at roughly $530 to $720. Every price we give is in writing after we see the tree.
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Emergency tree removal | $500 – $3,500+ | Time of day, damage to the structure, crane or bucket truck needed |
| Tree removal | $300 – $2,500+ | Height, trunk width, access, nearby buildings and lines |
| Tree trimming and pruning | $250 – $1,500 | Tree size, number of trees, how much is removed |
| Cabling and bracing | $300 – $900 per tree | Number of cables or rods, height of the install |
| Stump grinding | $100 – $450 per stump | Stump width, root spread, rocks, how deep you want it |
| Tree health assessment | $100 – $400 | Number of trees, written report, lab testing |
Ranges are estimates for planning only. Ask about a lower rate when several trees or stumps are done on one visit.
Trees That Grow Well in Longmont, Colorado
The City of Longmont publishes a list of recommended trees for its streets and parks, and it's a good guide for private yards too. Ash isn't on it anymore, and neither are silver maple or Siberian elm. These five from the list handle Longmont's dry summers, alkaline soil and heavy spring snow better than most.
Bur Oak (Quercus macrocarpa)
A slow, tough shade tree with thick corky bark and big acorns. Deep roots help it ride out drought, and the strong wood holds up well to wind. Give it room: a mature bur oak can spread 60 feet or more.
Kentucky Coffeetree (Gymnocladus dioicus)
Bold, open branches and very few pests make this one of the best replacements for ash trees lost to emerald ash borer. It handles alkaline soil and dry spells. The city's list recommends seedless male varieties like Espresso, which skip the messy pods.
Rocky Mountain Juniper (Juniperus scopulorum)
An evergreen that stays green all winter and needs very little water once it's established. It works well as a windbreak or screen and comes in narrow upright forms for tight spaces.
Common Hackberry (Celtis occidentalis)
A forgiving street and yard tree that takes heat, wind, poor soil and drought. Its small berries feed birds in winter. It grows at a medium pace into a rounded, elm-like shape.
Colorado Blue Spruce (Picea pungens)
The classic blue-gray evergreen, and still on Longmont's list. It looks best with room around it and a deep drink during dry winters. The city flags tussock moth as a concern in large spruces, and needle cast shows up on stressed ones.
Planting and Care Tips
Plant so the root flare, where the trunk widens at the base, sits right at the soil surface, not buried. Dig the hole two to three times wider than the root ball but no deeper. Put 2 to 4 inches of wood-chip mulch in a wide ring, kept a few inches off the trunk. Water deeply and slowly for the first two to three years, including during dry, mild spells in winter. Skip heavy pruning for the first year except for broken or dead branches. A young tree that gets a little structural pruning every few years needs far less work as it gets big. Planting in the strip by the street? Longmont requires a Forestry permit, a call to Colorado 811 first, a species from the city's list, and about 15 gallons of water a week in the growing season for the first two years.
Caring for Drought-Stressed Trees in Longmont
Longmont sits on the dry side of the Front Range: hot summers, low humidity and long winter stretches without snow on the ground. On May 12, 2026, City Council moved Longmont to a mild drought response, and the city has stayed at that level since. The city cut its own water use on parks and greenways and asks residents to save water too, though nothing is mandatory for homeowners right now.
Less water on the lawn usually means less water for the trees growing in it. A dry year rarely kills a mature tree outright, but it weakens it, and the damage often shows up a season or two later as dieback, borers or disease. The Colorado State Forest Service warns that overly dry trees become open to root and branch dieback and the insect and disease problems that follow.
Signs a Tree Is Short on Water
Watch for these, especially in late summer and after a dry winter:
- Leaves browning at the edges and tips while the middle stays green
- Leaves wilting or curling in the afternoon heat
- Early fall color or leaves dropping in August
- Smaller leaves than usual and a thinner canopy
- Dead twigs at the ends of branches or at the top of the tree
- Evergreen needles browning from the tips inward
How to Water a Tree Deeply
Short sprinkler cycles wet the grass and miss most of the tree. Most of a tree's absorbing roots sit in the top foot of soil and spread well past the edge of the branches, so slow, deep watering over that whole area does far more good. The Colorado State Forest Service's guide, which the City of Longmont shares, works out to about 10 gallons per inch of trunk diameter each time you water. A soaker hose or drip line on low, laid in a ring around the drip line, is the easiest way to get it there. Water in the early morning or evening so less is lost to evaporation, and keep 2 to 4 inches of wood-chip mulch over the root zone, pulled a few inches back from the trunk.
Don't Skip Winter Watering
Dormant trees still lose water through dry, windy Longmont winters. The city asks residents to water trees once a month from October to April while drought conditions continue. Pick a day above 40 degrees with no snow on the ground, water around midday so it soaks in before the night freeze, and start again whenever two weeks or more go by without lasting snow cover. Young trees and evergreens need it most.
When to Have a Tree Looked At
If a tree still looks stressed after a few weeks of good watering, the problem may be more than water: compacted or buried roots, girdling roots, iron chlorosis from Longmont's alkaline soil, or emerald ash borer in an ash. A tree health assessment checks the roots, soil and canopy and tells you what's going on before you spend money on the wrong fix. A little attention before something breaks goes a long way.

What to Expect on a Regular Tree Job
Most of our work isn't an emergency. Here's how a planned removal, trimming or stump job goes from the first call to the last rake.
An On-Site Look and a Written Estimate
We come out, walk the property with you and look at the tree, what's under it and how the wood will get out: gate width, alley access, slopes and overhead lines. You get a written estimate that spells out what gets cut, what stays, whether the stump is ground and what cleanup includes, so there's nothing to guess at later.
Permits and Calls Handled Before the Work Day
If the tree is a city street tree in the right-of-way, Longmont Forestry has to sign a permit first, which takes up to five business days. If branches tangle with the line running to your house, we arrange the free service-line disconnect from Longmont Power & Communications. Before stump grinding, buried utilities get marked through Colorado 811.
Your Lawn, Driveway and House Protected
We park and set up where you've agreed, lay plywood or ground mats where heavy equipment crosses soft lawn, and lower limbs by rope over roofs, fences, decks and garden beds instead of dropping them. Cars get moved out of range, and anything fragile in the yard gets moved or covered first.
The Work, Done the Way We Agreed
The crew works from the written plan. If something turns up mid-job, like hidden rot or a nest in the canopy, we stop and talk to you before doing anything beyond what was agreed or changing the price.
Cleanup and a Final Walkthrough
Branches go through the chipper, logs are hauled or stacked where you want them, and the lawn, beds, driveway and gutters are raked and blown off. Before we leave, we walk the property with you to check every item on the estimate is done and the yard looks the way it should.
What Happens When You Call Longmont Tree Company in an Emergency
You Call, We Ask the Right Questions
Is anyone hurt? Is the tree touching power lines? Is it on the house or blocking the only way out? Your answers tell us what to bring and how fast we need to move.
A Crew Heads Your Way
We send people and equipment sized for the problem, whether that's a chainsaw and a truck or a bucket truck for a tree hung up in other trees.
We Make the Site Safe First
Weight comes off the roof first, then hanging limbs get cut down and the area is taped off. Power lines are left to Longmont Power & Communications. Tarping the damage until repairs is part of the job.
Cleanup and Insurance Paperwork
Once it's safe, we clear the debris and give you photos and an itemized invoice for your insurance claim. If you want the stump ground or the rest of the tree removed, we can schedule it.

How much does tree removal cost in Longmont, CO?
Size matters most. As a rough guide for an open yard with easy access:
- Small trees under 30 feet: about $300 to $700
- Medium trees 30 to 60 feet: about $700 to $1,500
- Large trees over 60 feet: $1,500 and up
- Add for tight access, nearby lines or roofs, or a crane
Do I need a permit to remove a tree in Longmont?
For a city-owned street tree in the right-of-way, yes. The owner of the property next to it applies to Longmont Forestry Services, which answers within about five business days. The work has to be done by a city-licensed contractor and include stump grinding. Longmont also requires every tree contractor working in the city to hold a city tree license. For trees fully on your own lot, we'll check the rules for your address before we schedule.
How do I know if my tree should come down or can be saved?
These signs point toward removal:
- Half or more of the canopy is dead
- Mushrooms, conks or soft wood at the base
- A crack running down through the main fork
- The tree has started leaning when it didn't before
- Roots lifting on one side of the trunk
Is emerald ash borer in Longmont?
Yes. It was confirmed in Longmont in June 2016, near 9th Avenue and Hover Street, three years after it was first found in Boulder. Longmont had an estimated 43,000 ash trees at the time, and untreated ash trees die once the beetle builds up. Signs to watch for:
- Thinning leaves and dead branches starting at the top
- Bark splitting with S-shaped tunnels underneath
- Small D-shaped exit holes in the bark
- Woodpeckers working on the trunk
When is the best time to trim trees in Longmont?
Late winter, while trees are dormant, is best for most species. Wounds close faster once spring growth starts, insects that spread disease are inactive, and with the leaves off we can see the branch structure clearly. Dead or broken limbs can come off any time of year.
How much does stump grinding cost?
Most single stumps run about $100 to $450, depending mainly on the width of the stump and how far the roots spread. Extra stumps on the same visit cost less each, and grinding is cheapest when it's done the same day as the removal.
Which trees get removed most often in Longmont?
The ones we expect to see coming down most often:
- Ash trees killed or weakened by emerald ash borer
- Limbs and trees split by wet spring snow
- Pears and goldenraintrees, which the city's tree list flags as prone to snow and storm damage
- Siberian elms and silver maples with weak, heavy limbs
- Cottonwoods, which grow fast with brittle wood
Do you offer 24/7 emergency tree service in Longmont?
Yes. Our phone is answered day and night for trees on houses, cars or driveways. If a tree is on a power line, call Longmont Power & Communications at 303-651-8386 first and stay back. Then call us at (303) 578-5969.
What are cabling and bracing, and when does a tree need them?
Cabling ties major limbs together high in the canopy with steel cable so they share the load. Bracing puts threaded rods through a weak fork or a crack. They make sense when:
- The tree is worth keeping and is otherwise healthy
- The weak point is a fork or split, not rot at the base
- There's enough solid wood to anchor the hardware
Are you licensed to do tree work in Longmont?
Yes. Longmont requires every tree contractor working in the city to hold a city tree license, and the city publishes the list. We're happy to show you ours, along with proof of insurance, before any work starts.
Do you have an ISA Certified Arborist?
Every company on the City of Longmont's licensed tree contractor list has an ISA Certified Arborist on staff, so any crew licensed to work in the city has one. ISA certification means the arborist passed the International Society of Arboriculture's exam and keeps up continuing education. You can check any arborist's credential on the ISA website before you hire.
Are you insured, and are estimates free?
Yes. We carry general liability and workers' compensation and will send a certificate of insurance before work starts. That matters: without workers' comp, an injury on your property can land on you. Estimates are always free and in writing.
