About Hamilton Tree Service, Inc.

Hamilton Tree Service, Inc. is a tree service based in Martinez, California, working across the Bay Area from a yard at 4949 Pacheco Blvd. Dex Hamilton started the business in 1957, and his son Grant Hamilton took over in 2000. The county it serves is Contra Costa, and the places named include Martinez, Walnut Creek, Concord, Pleasant Hill, Lafayette, Orinda, Moraga, Danville and San Ramon. The crews handle tree removal, pruning, stump removal, land clearing, fuels-reduction clearing, emergency tree service and crane work. They take on homeowners and ongoing programs for HOAs, municipalities, government and commercial sites. The species named are redwood and cedar. How a tree comes down depends on what is beneath it. Where there is room, they fell it. Where there isn't, climbers take it apart from the top, or a crane lifts sections out over the obstacle. That call is made on site, before anything is cut. Estimates are free. Brush and smaller wood are ground and screened into mulch. Logs worth milling go to a local sawyer to become slabs, mantels and benches, and what suits neither is burned as fuel at a co-generation plant. Nothing is left behind: "Everything that comes off the tree leaves with us." The licenses include a CAL FIRE Licensed Timber Operator number, an ISA Certified Arborist, TRAQ, a Qualified Applicator License and a CA State Contractors License, with $10 million combined insurance coverage. It suits a homeowner in Contra Costa County with a large redwood or cedar over a roof or a fence, who wants the tree taken down and the material carried away.
