Trimming and pruning is the most important tree work most homeowners will ever do — and the work that's done wrong the most often. North Woods uses ISA Certified Arborist expertise on every pruning job to make sure the cuts protect tree health for the long term, not just look good for a season. We provide crown reduction to control overall tree size, crown thinning to allow light and air through dense canopy, deadwood removal to eliminate hazards, structural pruning to correct weak branch unions and protect against future failure, seasonal pruning for fruit and ornamental trees, and clearance pruning to maintain space over homes, driveways, sidewalks, and power lines. We never top trees — topping is prohibited under most Portland-metro tree codes and damages long-term tree health regardless of city rules.
