Tree Removal, Trimming and More in Angwin
Fir and Oak Removal on the Mountain
We safely take down trees of any size in Angwin, from a tall Douglas fir crowding a family home near Pacific Union College to a big oak leaning over a remote hillside parcel out on the mountain.
Pruning Against Howell Mountain Wind
We shape the canopy, clear the deadwood, and cut back the limbs reaching over your roof, your deck, or the power lines, then thin the heavy crowns so the strong mountain winds that sweep across Howell Mountain have less to grab.
Defensible Space in the Forest
We handle defensible space and brush clearing to CAL FIRE standards, pulling out the ladder fuels and the dead or overhanging trees that put a forested property at risk, while leaving the healthy canopy in good shape.
Stump Grinding in Rocky Ground
On Angwin’s rocky, wooded lots an old stump is often right where you want the space. We grind it out below grade so you can replant or lay sod.

✓ ISA-certified arborists on every estimate.

Our Crew on the Job
Tall Firs and Oaks Up on Howell Mountain
Angwin sits high up on Howell Mountain, well above the Napa Valley floor, where it is cooler and wetter and the trees grow in rocky, fast-draining ground. That higher elevation, the wind exposure, and the steep terrain all change how trees grow and how they need to be cared for. Whether you have a family home near the college or a remote hillside parcel, we know the mountain and we will take good care of your trees up here.

Victor contacted me within hours of requesting an on-line contact. By the afternoon, he had come to the house and given me an estimate. The removal of two trees was done a few days later. The crew arrived early and were professional, respectful, efficient and friendly. The clean up was well done. I can highly recommend this company.Posted on Google![]()

I was thoroughly impressed with Diego's punctuality and professionalism during the estimate. He made me feel welcome in my own home and provided a competitive and fair quote for redwood removal, as well as trimming my beautiful Japanese maple. I will definitely consider hiring them again for spring tree trimming. The team was efficient and handled the plants around the work area with great care. I highly recommend their services and extend my full respect for their work. They truly deserve 5 stars!Posted on Google![]()

I have been a contractor in Sonoma and Marin counties for 45 years, I have used a lot of different tree companies in the past…Treeex is by far the best tree company I have used! Their equipment is top of the line, their safety protocols are also at the top and start time and finishing time was exactly what they quoted. They showed up with 6 excellent workers and the property at the end of the job was perfectly cleaned up. I would highly recommend for any small or large job!Posted on Google![]()

I recently hired TreeEx, for tree care on my property, and they did a great job. The team was professional, knowledgeable, and took the time to explain what they were doing and why. They handled the work safely, cleaned up thoroughly, and left my yard looking much better than before. I really appreciate their attention to detail and would definitely recommend them to anyone needing expert tree service. MahaloPosted on Google![]()

Detailed Proposal
Clear pricing breakdown. Understand the scope, timeline, and total cost before we begin.

What People Ask Us First
Sometimes. Some North Bay cities and counties protect heritage or native trees, so we check the rules for your lot before any work starts.
Usually $1,500 to $3,500, depending on the tree and how easy it is to reach. The price is in writing before we start.
Late summer into early fall for most trees, and brush cleared before the fall winds. Emergencies we handle any time.
A Closer Look at Each Service
Angwin sits high atop Howell Mountain at around 1,800 feet, well above the Napa Valley floor, where the cool, wet forest of firs, madrones, and oaks grows in rocky, fast-draining volcanic soil.
When a Tree Has to Come Out
The steep ground, the wind exposure, and the tight, wooded access up here are exactly the kind of removal we are set up for, with careful rigging and a crane when the drop zone is small.
Keeping Angwin’s Trees Healthy
The native oaks get pruned in the dry summer window, since cutting them in the wet season opens the door to disease, and the tall firs and madrones get the structural care they need to handle the elevation and the weather up here.
Grinding the Stump Down
We grind it down and leave the spot ready for sod or a garden.
Storm and Fire-Season Ready
Angwin’s cool mountain forest is beautiful, but it also sits in high wildfire country, where homes tucked into the firs and oaks face real risk when the dry fall Diablo winds come down off the mountain.
