Credentials & honors

A1 Tree Service LLC sticks to trees and the ground around them: removal, pruning and trimming, stump grinding, land clearing, broken branch removal, and storm damage cleanup with chipping and hauling. The crew works out of Deer Park and covers the north side of Spokane County and beyond, from Colbert, Mead, Elk and Chattaroy down into Spokane, Spokane Valley, Airway Heights and Liberty Lake. The company advertises 24/7 emergency service and same-day response after storms.

Public agencies make up a good share of the work. Since 2017 A1 has filed prevailing-wage jobs for Spokane Parks & Recreation, the cities of Spokane, Spokane Valley and Liberty Lake, the Town of Millwood, Spokane Valley Fire Department, Spokane County Fire District 8, SNAP and the Washington State Department of Transportation, mostly as prime contractor. The state insures the business under tree care and logging classes, which fits the removal and clearing side of the list. The company says it has an ISA Certified Arborist on the team, and the state lists Lewis Harm and Sapphire Harm as principals since 2018. A predecessor business under the A1 Tree Service name dates to 2016, and the crew runs in the 11 to 20 range. That mix suits a homeowner with a downed limb on the roof after a windstorm, a stand of trees to clear on acreage around Nine Mile or Five Mile, or a yard that needs regular pruning to keep big pines and maples healthy. A1 is a tree outfit, not a builder, so repairs to a fence, roof or deck after a storm will need a separate contractor once the wood is cleared away. Tree work in Spokane follows the weather. Windstorms and heavy wet snow bring a rush of emergency calls, and planned work gets pushed back while crews clear hazards. Late winter and early spring, while trees are dormant and leaves are off, is a good window for pruning and removals, and it fills up fast. Book routine pruning and stump grinding well before summer, and get on a schedule ahead of fire season if you want brush and ladder fuels cleared on a rural lot north of town.
