Custom Garages Built for the Colorado Mountains
Construction That Handles the Elements
Built for the High Country
Living in Silverthorne and across Summit and Grand Counties means dealing with serious winter weather. We build garages specifically to handle the heavy snow loads and extreme temperature swings that come with mountain life. From reinforced foundations to high-grade insulation, we make sure your building is tough enough to stay warm and sturdy no matter what the season throws at it.

More Than Just a Place to Park
Spaces for Your Mountain Life
A garage should do more than just house a car. We design spaces that fit how you actually live, whether that means extra-tall bays for an RV and a boat or dedicated storage for your skis, bikes, and camping gear. We also build separate workshops, home gyms, or creative studios, ensuring every square foot is useful and built to your needs.

Matching Your Existing Style
A Natural Fit for Your Home
Your new garage should look like it was always meant to be part of your property. We pay close attention to the details, matching your home's siding, roofing, and trim so everything looks cohesive rather than like an afterthought. A well-integrated outbuilding doesn't just look better; it adds real value to your home and fits perfectly into the local landscape.

We Handle the Details from Start to Finish
Simple, Stress-Free Building
Dealing with building codes and permits in the mountains can be a headache, but Action Builder LLC takes care of all of that for you. We manage the entire process, including all the paperwork and inspections required in our local communities. Most builds are finished within six to ten weeks, and we provide daily on-site oversight to ensure the work meets our high standards.
