Building the future, Restoring the past
to see your project go from idea through completion
From foundations and concrete to remodeling, siding, and roofing, Vertex Construction can take on projects from the ground up.
Calen brings more than two decades of hands-on Montana construction experience to every project.
Your goals guide the work. Vertex listens carefully and builds with your property, priorities, and satisfaction in mind.
Building runs in the family. Calen grew up around construction and a family-owned lumberyard in Eastern Montana.
Clear answers and honest conversations keep everyone on the same page from the first estimate to the finished project.
From home repairs and remodels to new construction and major civil projects, every job receives professional attention.
Every job is quoted before we start. No surprises on the invoice.
Remodels and renovations involve improving and updating an existing space to better fit your needs, style, and functionality. From targeted upgrades to larger-scale transformations, we provide quality workmanship and dependable service throughout every phase of the project. Our focus is on delivering a finished space that is practical, well-built, and tailored to your goals.
New construction is the process of building a structure from the ground up, whether it’s a new home, garage, shop, addition, or other type of project. This type of work gives you the opportunity to create a space that is built around your specific needs, layout preferences, and long-term goals. Instead of working around an existing structure, everything is planned and constructed to match your vision from the beginning.
A well-built sidewalk or concrete apron adds both function and curb appeal to your property. Sidewalks provide a safe, durable path for everyday use, while aprons create a smooth, strong transition between surfaces such as driveways, garages, barns, shops, and entry areas. Whether you need a new installation or replacement work, we focus on quality concrete work that is level, durable, and built to hold up over time. Our goal is to deliver a finished product that looks clean, performs well, and adds lasting value to your property.
Calen Larsen is the owner of Vertex Construction LLC and a third-generation Montana builder with more than 20 years of hands-on construction experience. He grew up around the building industry and a family lumberyard in Eastern Montana, where he learned that good work starts with showing up, doing what you say you will do, and treating people fairly. That foundation has carried through a career that includes residential construction and remodeling as well as larger civil projects across the state.
Today, Calen leads Vertex Construction from Hamilton, serving homeowners throughout the Bitterroot Valley with new construction, remodels, additions, roofing, siding, concrete, and more. He brings a practical, hardworking approach to every project and believes clear communication is just as important as quality craftsmanship. Whether the job is a small repair or a major home improvement, Calen works to make the process straightforward, professional, and comfortable from the first conversation through completion.
Vertex Construction is built on the Montana values Calen grew up with: honest work, respect for the customer, and pride in a job done right. He enjoys helping people turn a rough idea into something real and lasting, while keeping their goals, budget, and timeline in view along the way.

Addition Framing"Vertex is responsive, professional and reliable. They did a great job with our concrete repair project where unexpected issues occurred. I appreciated his willingness and drive to get this completed in one visit. Our customer was very happy with the outcome!"
"As the owner of a remote property in Montana I've used a number of contractors over the years, but by far the best I've worked with is Calen Larsen of Vertex Construction in Hamilton. The most recent project he finished for me was replacing all the windows on Western, Southern, and Eastern sides of my home. He completed the work on schedule and cost. Simply put, he's best and I won't use anyone else."
"We are so thankful to Vertex for taking on the challenges of our job. Vertex had their hands full with the combination of a hand built homestead house and clients that had no clue about what was needed to do the requested job. They powered through the many supply chain setbacks and resulting weather conditions. Rolling with each issue as it developed as well as the requested addition of a handicapped ramp mid job. They worked with local people to get the multiple facets of the job done. Through the many frustrating challenges they remained professional, flexible, and respectful."
