About Catalyst Custom Construction in Sun Prairie, WI

Catalyst Custom Construction is a Sun Prairie, Wisconsin–based builder and remodeler focused on residential new construction and home remodeling. We work with homeowners who want a space that feels intentional—built with solid craftsmanship, clean finishes, and materials that hold up to real daily life in Wisconsin.

A company built on craftsmanship and trust

Catalyst Custom Construction has been serving homeowners since 2015 and is led by owner Mike Hessling. From the start, our approach has been simple: do the work the right way, communicate clearly, and deliver results you’re proud to show off. We believe quality isn’t just about what you see at the end—it’s the planning, the prep, and the details behind the walls that protect your investment.

Home projects can be stressful when communication is unclear or expectations shift midstream. That’s why we put a strong emphasis on clarity early: what you want to change, what success looks like, what matters most (function, style, timeline, budget), and how we can guide the process from concept through completion.

What we do

Catalyst Custom Construction specializes in new home construction and remodeling, with services that cover full builds as well as focused renovations. If you’re updating one room or transforming an entire home, we bring the same mindset to every job: thoughtful planning, durable construction methods, and finish work that looks clean and professional.

Our core services include:

  • Custom home construction and complete home builds
  • Home additions that expand living space and improve flow
  • Kitchen remodeling including layout improvements, cabinetry installs, countertops, lighting, and finish details
  • Bathroom remodeling such as custom tile showers, vanities, flooring, and fixture updates
  • Basement finishing and remodeling for family rooms, offices, guest space, and wet bars
  • Carpentry and interior trim that completes the space with crisp lines and polished details
  • Custom porches and exterior features to extend your home’s usable space

Local knowledge, Wisconsin-ready builds

Because we’re based in Sun Prairie, we understand the homes, neighborhoods, and seasonal realities that shape good construction decisions in this area. Wisconsin weather demands durable building practices—especially in moisture-prone spaces like bathrooms and basements, and in high-use spaces like kitchens. We help homeowners select materials and finishes that look great while standing up to real-world wear.

How we work: clear scope, clean execution

Many homeowners want more than a contractor—they want a partner who can guide decisions and keep the job organized. Catalyst Custom Construction supports clients from the design and planning stage through the final finishing work, helping align the vision with practical decisions like scope, sequencing, and selections.

Our process is built around a few key principles:

  • Listen first. We get clear on how you want the space to function and feel.
  • Plan with intention. We define the scope and the critical details before work begins.
  • Build with consistency. We focus on clean framing, proper prep, and professional installation.
  • Finish strong. Trim lines, transitions, alignment, and small details are what elevate a project.
  • Communicate throughout. You should always know what’s happening, what’s next, and what decisions are needed.

Reputation and client experience

Homeowners often describe Catalyst Custom Construction as responsive, detail-oriented, and flexible through the project—especially when it comes to guiding decisions and delivering a modern, updated result. We take that seriously. Our goal isn’t just to complete a job; it’s to deliver an end result that feels well-built, well-finished, and worth the investment.
