Tree Pruning & Trimming in Napa, Sonoma & Lake Counties
Good pruning keeps a tree healthy, strong, and safe for decades. Bad pruning does the opposite. Denbar Tree Service prunes to protect the tree first, so it isn’t just cut back to look tidy.
We’re based on Howell Mountain in Angwin and work on hillside, wooded, and vineyard-edge properties across wine country.
What We Do
-
Deadwood removal. We take out dead, broken, and hanging limbs before they fall.
-
Crown thinning. We open up dense canopies to reduce weight and wind resistance and let light and air through.
-
Canopy raising. We lift low branches for clearance over driveways, roofs, walkways, and vehicles.
-
Structural pruning. We shape young and mature trees for long-term strength.
-
Overgrown tree cleanup. We bring neglected trees back under control without removing more than the tree can handle.
-
Fire-safety limbing. We trim low branches to keep a ground fire from climbing into the canopy. This is part of our wildfire mitigation and defensible space work.
Our Approach to Pruning
-
We remove only what the tree needs removed.
-
We make clean cuts in the right places so the tree can heal.
-
We use rigging to lower large limbs when there’s no room to drop them over a house, fence, or garden.
When to Prune
-
Branches are dead, cracked, or rubbing together
-
Limbs hang over your roof, driveway, or power lines
-
The canopy is so dense that little light gets through
-
A tree has grown into a structure, fence, or view
-
You’re preparing a property for fire season or an insurance inspection
-
A branch has been damaged by wind or storms
If a whole tree looks unsafe, rather than just its branches, see our page on hazard tree removal.

Frequently Asked Questions
What’s the difference between pruning and trimming?
People use the words interchangeably. Either way, the goal is to remove the right branches for the tree’s health and safety, not to remove as much as possible.
How often should trees be pruned?
It varies by species and age, and many trees do well with a check every few years.
Will pruning hurt my tree?
Done correctly, no. Pruning at the wrong time or removing too much can stress a tree, which is why we assess each one before we start.
Do I need a permit?
This depends on size and location of tree. Many trees located within city limits require permits.
Can you prune and clear brush in the same visit?
Yes. We can combine pruning with brush clearing and fuel reduction.
