Mountain Remodeling Built for High-Country Life
Your Silverthorne, CO, and all of Summit and Grand Counties Home Remodeling
Built for the Colorado High Country
Real-world experience building in the High Rockies.
Silverthorne Locals Who Know the Territory
Action Builder LLC is led by owner and General Contractor Ron Walsh. We serve Silverthorne and the rest of Summit and Grand Counties with the kind of reliability you only get from someone who actually lives here. Building in the Rockies is its own challenge because you have to account for extreme temperature swings, intense UV rays, and massive snow loads. Ron is on-site every day to make sure every detail is handled with the precision that high-altitude building requires.
Combining rugged durability with modern comfort.
Built to Withstand the Alpine Climate
A house at 9,000 feet needs more than standard building practices. We focus on the specifics that really matter here, like radiant floor heating and high-performance insulation to keep you warm during the coldest winters. When we renovate a kitchen or a primary suite, we choose materials like quartz and engineered wood that won't just look good but will actually hold up in our dry and demanding climate.
We take the stress out of mountain renovations.
Managing Your Project from Start to Finish
We take care of every step, from the first design sketches to the final walkthrough. Dealing with local zoning and building permits in Summit and Grand Counties can be a headache, so we handle all of that paperwork and the inspections for you. Our goal is to modernize older homes while keeping their original mountain character, giving you a space that works for your life and adds real value to your property.
Expanding your home's footprint and functionality.
Making the Most of Your Space
We help you get more out of your property, whether that means a multi-level deck built for snow loads or a new accessory dwelling unit. We specialize in making additions feel like they were always part of the house by matching your existing architecture and siding perfectly. From functional mudrooms for all your outdoor gear to detached garages and guest houses, our builds are designed for both style and long-term stability.

What Homeowners Are Saying
- Randy Nuss
Ron and his team (Scott on our project) did a wonderful job on our kitchen and bathroom remodeling project. Their suggestions on granite and tile vendors, as well as suggestions for design improvements, were spot on.
The project was completed timely and within the budget. We will certainly use them again for future projects.
- Jeff Proctor
I met Ron, the owner of Action Builders and liked his professional manner from the start. Our company required him to become a vendor and that required lots of paperwork. This was completed in a timely manner and we had our GC for our big project.
The quality of the work was top notch and all of his crew were knowledgeable and professional as well.
-HU-136316
We had such a great experience working with Action Builder for our complete remodel. We were managing the project from another state so communication and trust were imperative throughout the process. Ron was responsive, honest and fair. His attention to detail was superb and he wanted to make sure we were happy with the final product. Highly recommend!
- Pat Barney
Ron is honest, creative, artistic and professional. He had great ideas and handled our concerns in a timely fashion. We are very happy with the results of our project. We highly recommend Action Builder LLC
- Laura James
Ron and his crew did a fantastic job on an extensive interior remodel, excavation, retaining walls and brand new deck build. Ron was timely in his communication and most important does business with integrity. We would recommend Ron.
- Rob Dieckhaus
My wife and I have had Action Builder to two renovation projects on our Frisco condo. We were pleased with Ron's responsiveness, professionalism, and quality of work. We wouldn't hesitate to use him again.
- Bob Thornton
We added a detatched two car garage with an overhead apartment to our Dillon house. The project was well build (comments from city inspectors). We were very satisfied with the process and the end product. The contractor was there daily, worked issues quickly and produced a quality structure. I would recommend Ron for any major construction project/remodeling project you are considering.
- Alaina L
We worked with Ron for a mountain condo remodel. He was very knowledgeable and helpful along the way as we had questions or needed suggestions on what to do. Since we weren't living where the remodel was occurring, he was great at communicating and sending progress pictures as he went! He guided us right on a few things we weren't sure about as to how to proceed...his expertise paid off! We were really pleased with how things finished, and the professionalism from start to finish!
- John Alfeld
Ron and his crew did a remodeling job for me in Silverthorne. I was totally satisfied with their work. Ron's bid for the job was the best of the three and his plan for the job was complete. He kept me informed of the progress with pictures and explanations. They accomplished the job in a timely manner, never letting the site sit for an extended period without working on it. I was totally satisfied with the results. I always felt during the process that he was above-board with me and committed to my satisfaction.
