Tree Removal, Trimming and More in St. Helena
Valley Oak and Hillside Removals
We safely take down trees of any size in St. Helena, from a tired ornamental in a Main Street backyard to a big valley oak hanging over a hillside home up off the Silverado Trail.
Pruning Estate Trees
We shape the canopy, clear out the deadwood, and cut back the limbs reaching over your roof, your patio, or the power lines, then thin the heavy crowns so the trees hold up through the heat and the fall winds.
Fire-Fuel Clearing on the Slopes
We handle defensible space and brush clearing to CAL FIRE standards, pulling out the ladder fuels and the dead or overhanging limbs that put a home at risk while leaving the healthy oaks, which hold up well to fire, in good shape.
Stump Grinding on Valley Lots
On St. Helena’s close-set valley lots an old stump is usually right where you need the room. We grind it out below grade so you can replant or lay sod.

Valley Floor and Hillside Trees in St. Helena
St Helena sits in the narrow heart of Napa’s wine country, where the valley pinches in tight between the hills. That means warm days and cool nights, and trees that range from big old oaks out on the benchlands to the carefully kept canopies shading Main Street. Whether you have a cottage on Adams Street or a hillside estate off Silverado Trail, every property here is a little different, and your trees need care that fits the spot.

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![]()

Sometimes. Dead or hazardous trees are usually exempt, but protected trees can need a permit, so we check first.

Late summer into early fall for most trees, and brush cleared before the fall winds. Emergencies we handle any time.
Removal, Trimming, Stumps and Storms
St. Helena sits in the narrow heart of Napa’s wine country, where the valley pinches in tight between the hills and the canopy gets packed in close, from big old oaks out on the benchlands to the shade trees lining Main Street.
When a Tree Has to Come Out
Lots run tight here and the canopy is concentrated, so we rig the tree down in pieces and bring in a crane when the drop zone is small, keeping your house, your fence, and the neighbor’s roof out of harm’s way.
Keeping St. Helena’s Trees Healthy
The native oaks out on the benchlands get pruned in the dry summer window, since cutting them in the wet season opens the door to disease.
Grinding the Stump Down
We grind it below ground level and clean up the chips.
Storm and Fire-Season Ready
St. Helena sits in real fire country, and the Glass Fire put that on everybody’s mind, so even a fire burning a ridge or two away can throw embers into a dry yard.
