Tree Trimming Service in Northglenn, CO

Tree trimming is one of the most common calls we get, and it is also one of the most misunderstood. Trimming done right improves the tree’s structure, reduces future problems, and keeps your property safer. Trimming done wrong, meaning cutting too much, leaving stubs, or topping a tree, causes lasting damage.

What We Actually Do When We Trim a Tree

Good trimming starts with understanding what the homeowner needs and what the tree needs. Before we cut anything, we look at the tree’s structure, identify which branches are the problem, and plan the cuts.

On a standard residential trimming job, we:

  • Remove dead, broken, and crossing branches first
  • Clear any branches rubbing on the house, roof, fence, or utility structures
  • Thin the canopy selectively if it is too dense, taking care not to remove more than is healthy for the tree
  • Raise the lower canopy if low hanging branches are a clearance issue
  • Make clean cuts just outside the branch collar, which is where the branch meets the trunk, so the tree can seal over the wound properly
  • Chip or haul all material and clean the site

We do not top trees. Topping removes large sections of the main trunk or major limbs and leaves wounds the tree often cannot close, leading to decay, weak regrowth, and a tree that is worse off than before. If another company has recommended topping your tree, it is worth getting a second opinion before agreeing to that work.

Reasons Northglenn Homeowners Call Us for Trimming

  • Branches hanging over the roof or rubbing on the house
  • A tree that has grown too wide for its space
  • Dead limbs visible in the canopy
  • Low hanging branches blocking the driveway or a sightline
  • A tree that was never shaped properly and has developed a bad structure
  • Branches overhanging a neighbor’s property

We get a lot of trimming calls from homeowners in the older Northglenn neighborhoods near 104th Avenue and around Malley Drive, where mature cottonwoods and elms have had decades to spread. We also regularly work in Westminster along the Huron Street corridor and in Federal Heights, where smaller yards mean overhanging branches become a concern sooner. In the newer subdivisions in Thornton and Broomfield, maples, honeylocusts, and ornamental trees planted at build time are starting to reach a size where they need their first real shaping.

The Trees We Trim Most in the North Metro

Northglenn and the surrounding area has a mix of species. The trees we trim most often:

  • Cottonwood: fast growing and common along ditches and in older yards; needs regular attention to control size and deadwood. A recent job reached the highest dead branches on a cottonwood in the 75 to 80 foot range.
  • Elm: mature elms in older Northglenn and Federal Heights neighborhoods develop heavy canopies that benefit from periodic thinning.
  • Ash: declining ash trees in the north metro need careful trimming to manage deadwood before full removal becomes necessary.
  • Blue spruce and other conifers: shape trimming and clearance work.
  • Honeylocust, maple, and ornamental varieties: common in newer subdivisions across Thornton and Broomfield.

Timing: When to Trim in Colorado

For most deciduous trees, late winter to early spring is ideal. The leaves are off, the structure is easy to see, and the tree responds well to cuts made just before the growing season begins. Summer trimming is fine for clearance work and deadwood removal. Hazard branches, meaning dead limbs, broken branches, or anything hanging over a structure, should come down as soon as you notice them, regardless of season. We work year round.

Colorado’s weather adds some extra reasons to stay on top of trimming. Wet spring snowstorms are common in the north metro and add a lot of weight to branches that are already long or poorly structured. Trees that are trimmed regularly handle that load better than trees that have not been touched in years. After a heavy snow, we often get calls from homeowners whose trees dropped limbs they had been meaning to address for a while.

What Does Tree Trimming Cost in Northglenn?

Cost depends on the number of trees, their size, how much work is needed, and site access. A single small ornamental tree is a quick job. A large cottonwood in a tight backyard takes more time and planning. We give you a written quote before any work begins so you know exactly what you are paying. There is no charge for the estimate, and the number on the proposal is the number on the invoice.

Tree Trimming Questions

How much does tree trimming cost in Northglenn, CO?

It depends on the number of trees, their size, and the scope of the work. We give you a written quote before starting, and there is no charge for the estimate.

How often should my trees be trimmed?

Most residential trees benefit from work every two to three years. Fast growing species like cottonwood may need more frequent attention. We can tell you after we see yours.

Can you trim a tree near power lines?

We clear branches near structures and fences. Branches in contact with or within a few feet of energized utility lines are Xcel Energy's responsibility. If your tree is touching a power line, call Xcel first.

Will trimming hurt my tree?

Proper trimming does not harm a healthy tree. Removing dead, damaged, and crossing branches actually helps the tree. The problems come from improper cuts, removing too much at once, or topping. We follow standard pruning practices to keep the cuts clean and the tree healthy.

Do you haul the trimmings away?

Yes. We chip and haul all material. Let us know if you want chips left for mulch.
