Service Area · Issaquah, WA
Issaquah sits between mature forest and growing neighborhoods, with Douglas fir, Western red cedar, bigleaf maple and other native trees woven through properties from the valley floor to the hillsides around Tiger Mountain and the Sammamish Plateau.
Tree care here often means working around mature canopy, steep slopes, critical areas and city tree regulations. Issaquah generally considers trees 6 inches DBH or larger to be significant, with different thresholds for alder and cottonwood, and permits are required for many tree removals and excessive pruning. We check the property and applicable requirements before the work begins.
