Meet the Team

Willow Creek Construction is a family-owned and operated business built on craftsmanship, integrity, and a passion for creating exceptional outdoor living spaces. Founded in 2019, our company was created to bring high-quality, long-lasting construction solutions to homeowners and builders who wanted more than standard, short-term products. We believe outdoor spaces should be just as functional, beautiful, and durable as the inside of your home.

​

Jon Williams has been in the construction and renovation industry since 2007. With a strong background in home renovations and a love for the outdoors, he quickly recognized a growing need for better solutions in deck construction and outdoor living. Homeowners wanted spaces that could truly be used in all seasons, especially dry, protected areas beneath their decks. After years of seeing products that didn’t meet his standards for quality or longevity, Jon committed to building and installing systems he could confidently stand behind.

​

Erica Williams joined the business full-time in 2021 after spending more than a decade as a nurse. Her background brings organization, attention to detail, and a deep commitment to client care into every project. Together, Jon and Erica manage every aspect of the company, from design and planning to installation and customer experience. When you work with Willow Creek Construction, you work directly with the owners.

​

Today, Willow Creek Construction specializes in engineered deck structures, premium under-deck ceiling systems, porch enclosures, screen systems, and infrared heating. We focus on products that are built to last, including steel-based waterproof ceilings and PWT Treated™ LVL deck framing, ensuring our projects are not only beautiful but structurally sound and durable for decades.

​

Our mission is simple: to transform underutilized outdoor spaces into functional, comfortable, and visually stunning extensions of the home. Every project is approached with the same care we would give our own homes, because for us, this is more than construction—it’s our family’s name and reputation on every build.
