Hazard Tree Removal in Napa, Sonoma & Lake Counties
A dead, leaning, or storm-damaged tree can fail without warning, and the risk is highest when it stands over a house, driveway, fence, or power line. Denbar Tree Service removes hazardous trees safely.
We’re based on Howell Mountain in Angwin, and steep, wooded, hard-to-reach properties are the ground we work on every day.
Signs a Tree May Be a Hazard
-
Dead or dying branches, or a canopy that’s thinning or has no leaves in season
-
A noticeable lean, especially a new one or one that’s getting worse
-
Cracks, splits, or hollow areas in the trunk
-
Fungus or mushrooms growing at the base
-
Lifted soil or exposed roots after a storm
-
Damage from fire, wind, or a neighboring tree falling
If you’re not sure, call us. We’ll look at the tree and tell you what we see.
How We Remove Hazard Trees
When there’s no room to drop a tree whole, we take it down in sections using rigging, lowering each piece under control so nothing lands on your home, vehicles, or fences. We also handle:
-
Trees close to houses, outbuildings, and driveways
-
Trees on steep slopes and in canyons
-
Storm-damaged and fire-damaged trees
