About This Market

Kent's landscaping market serves a mix of residential neighborhoods and commercial properties, with steady demand driven by the Pacific Northwest's year-round growing season and high homeownership rates. Competition is moderate with approximately 3,153 licensed establishments statewide, but quality work commands premium pricing. Projects range from basic maintenance to full landscape renovations, with irrigation and drainage work particularly valuable due to the region's wet winters and dry summers. Hardscaping and retaining walls are common due to Kent's varied topography. Washington's contractor licensing is straightforward but mandatory for jobs over $1,000. Kent has specific tree protection ordinances you need to understand before touching established vegetation. The wet climate means drainage planning is critical on every job, and customers expect contractors who understand local soil conditions and native plant requirements. Peak season runs March through October, so plan your crew capacity accordingly. Winter work focuses on pruning, planning, and hardscaping when weather permits.
