we are The King County Decks!
Founded by Max Kovalev and Sergey Kuyan, King County Decks was born out of a legacy of construction excellence. With over 23 years of hands-on experience building custom homes through their parent company, MJK Construction, the team earned a strong reputation for reliability, quality craftsmanship, and honest work throughout Oregon and Washington. Over time, satisfied homeowners began reaching out—not just for houses, but for outdoor spaces that matched the elegance and structural integrity of the homes they loved. Responding to this growing demand, Max and Sergey made the decision to launch a specialized branch focused solely on outdoor living.That’s how King County Decks came to life: a company dedicated to bringing the same high standards, attention to detail, and trusted project management into the world of custom deck design and construction. Today, we proudly serve clients across King County with the promise of quality that’s been built over decades—and the flexibility to tailor every project to your vision.
