Arbortec Tree Service

Emerald ash borer has been working its way through Colorado's ash tree population for years, and North Metro Denver properties are not immune.

The signs are easy to miss at first. Look for thinning canopy at the top of the tree, S-shaped galleries beneath the bark, D-shaped exit holes the size of a pencil tip, and increased woodpecker activity on the trunk. By the time bark splitting and sprouting appear, the tree has often been declining for several seasons. Early detection is the treatment window; late-stage infestation usually means removal.

Ash trees remain common in established Denver-area neighborhoods. If you have one and have not had it assessed recently, now is a good time. A certified arborist can evaluate whether a systemic insecticide treatment is still viable, or whether removal is the safer, more cost-effective path.

Happy 4th of July from Arbortec Tree Service! As we celebrate our nation's independence, let's not forget the beauty of nature around us. Whether you're enjoying a backyard BBQ or watching fireworks, make sure your trees are healthy and safe!

Today is Arborist Appreciation Day, and we think that's worth pausing on. The professionals in this trade work in all weather, at height, with heavy equipment, and they do it because they genuinely care about trees, properties, and the communities they serve.

Every healthy tree in your neighborhood has a story, and more often than not, a trained arborist is part of it.

Arborists do far more than remove trees. They assess structural risk, diagnose disease before it spreads, plan pruning schedules that protect long-term health, and make judgment calls that keep people and property safe. The work requires years of training, an understanding of biology, and the kind of physical skill that most people don't see until something goes wrong.

If a trained arborist has helped you protect a tree you love or safely remove one that was a hazard, today's a good day to say thank you.

Professional, efficient. The trees look fantastic and the team cleaned up all of the landscape, debris, leaves, etc. Thanks Arbortec and the duo team you sent out! We appreciate the work done!

Great experience, professional and respectful with reasonable prices. Do not confuse with Arbor Tech (I did and the experience was awful,terrible results and rude workers!) Arbortec is wonderful!
