About Cornerstone Handyman Services
Cornerstone Handyman Services is a family-owned and operated business proudly serving the Bothell, WA community.
Fresh out of high school, Duane launched his first business, Duane’s Landscape and Handyman Services, and quickly discovered his passion for helping homeowners maintain and improve their properties.
After two decades of hands-on experience, Duane explored other opportunities but eventually returned to his true calling. Guided by his Christian values, he rebranded the business as Cornerstone Handyman Services, with a renewed focus on providing reliable, affordable, and highquality handyman services.
We specialize in a wide range of services, including home repairs, emergency handyman services, trash removal, yard cleanup, move-in/move-out cleaning, and deep cleaning. Duane particularly enjoys helping the senior community, making homes safer and more comfortable, while also taking pride in projects like landscaping, cleaning, and flipping houses or apartments.
Founded by Duane Wilton, our journey began in 1983 when he started working for the Seattle Parks Department and continued in 1984 with Senior Services and Centers, performing minor home repairs.
Our goal is simple
to bring satisfaction, comfort, and a personal touch to every home we care for.

Duane did such a great job on my gutter repair and cleaning! Super easy to work with, great communication, and he even came out on short notice to get it done when I needed it. Really appreciate the quality of his work. Definitely recommend!
Jenta Hing
Duane came to fix a broken gutter and found moss blocking my downspouts. He cleaned them and moss off my shed. Pleasant, efficient and reasonable charge. I will request his services again.
