About This Market

UPDATED APR 2026

Kent's landscaping market runs hot with steady residential demand from established neighborhoods and new developments. Competition's thick with over 3,000 licensed outfits statewide, but quality work commands premium pricing. Projects range from basic maintenance contracts to high-end hardscaping for upscale properties. Costs get driven by material transport, permit delays, and the wet climate demanding specific plant selections and drainage solutions. Getting licensed in Washington isn't a weekend project - you need real experience or education, plus passing their exam that covers everything from soil science to business law. Kent's permitting process moves efficiently if you know the requirements upfront. Peak season hits hard March through October, so smart contractors line up winter work or use downtime for equipment maintenance. The rain creates year-round opportunities but demands contractors who understand Pacific Northwest conditions and can work around weather delays.
