Wyoming Fence Company

Our Fence Company - Wyoming

I'm Mark Olson, Founder and President of SWi Fence. My brothers and I started building fences for friends and neighbors more than 30 years ago with little more than a few tools and a commitment to do the job right. What began as a small family effort grew into a full-time business built on craftsmanship, dependability, and pride in our work. In 2014, Alan and I founded SWi Fence in Powell, Wyoming, and since then we've expanded across the state with multiple locations to better serve our communities.

Today, SWi Fence is proud to be Wyoming's largest and most trusted fence company. From residential projects to large commercial installations, our goal is simple—make the process easy and deliver a fence that stands the test of time. As active members of the American Fence Association, we hold ourselves to the highest standards of safety and quality, continuing the same dedication that's guided us since the beginning: earning trust, one fence at a time.

We started SWi with a simple idea: do good work for good people. Decades later, our foundation is still honest craftsmanship, reliable service, and fences that stand the test of time.

Our Core Values

Accountability, honesty, and trust aren't just words to us. They're the standards we hold ourselves to on every project.

Accountability

We stand behind every fence we build. If something isn't right, we make it right. That's how we earn trust: by showing up, owning our work, and delivering on every promise.

Honesty

We believe in being straight with people, with no gimmicks or shortcuts. Clear communication and fair dealing are what keep our customers coming back year after year.

Trust

Our reputation was built one fence at a time. We work hard to keep it by building strong relationships, standing by our word, and doing the job the way it should be done.

Meet the owner About SWi

I'm Mark Olson, founder of SWI Fence. After nearly three decades of fence building in Wyoming, I know the frustration of cheap materials and sloppy work. That's why our team makes it simple to get a fence that's strong, dependable, and built right the first time. My brother Alan and I built SWI on family values and craftsmanship - and today, homeowners, ranchers, and businesses across the state trust us to deliver fences that last. It's why SWI has become Wyoming's most trusted fence company.

"The wrong company leaves you with headaches.
The right one leaves you with a fence that lasts."
