How We’re Different

We offer general contracting for Colorado custom log homes or distinctive mountain homes. We only start one home at a time to ensure total focus and commitment to the build. GCI Co. offers customized upgrades to existing and new homes.

Involved Management

Successful construction projects are based on strong communication and trust. Our clients frequently cite open, clear communication as a distinguishing factor in working with us. Throughout your build, GCI management will be available on-site and by phone to answer questions and offer unique options for your project. Many of our subcontractors have worked with us for over a decade, and all of them are carefully screened for both the quality of their skillset and their on-site communication.

Comprehensive Custom

GCI specializes in comprehensive custom builds, offering our clients the ability to pair their vision with our experience. Comprehensive custom means that we manage every stage of construction in-house, allowing our clients to influence every important decision, from the floor plan to the light fixtures. One client said, “GCI made recommendations we never would have thought of. That’s experience speaking."

History of Excellence

For most families, the decision to build a custom home is the largest financial investment they will make in their lifetime. Hiring a general contractor is a momentous decision and should be accompanied by research- that’s why we offer a list of referrals with projects dating as far back as ten years. Our clients have a history of hiring us for additional work and recommending us to their closest friends and family. GCI has an established reputation for excellence and integrity in Northern Colorado.

An Eye for Excellence


Andy prides himself in the hands-on project management process for GCI. You will find Andy to be very much on top of your project with numerous innovative ideas and suggestions. With more than three decades of experience in project management, making Andy a very resourceful builder.


For over 10 years Andy designed almost every home he built. Drafting is no longer practical for Andy to do himself, but having him be part of your design phase will lead to a smoother build and more often than not, some significant savings.

Crew & Sub Contractors

GCI is very particular about who we hire as employees and sub contractors and demand high skill levels along with well developed respect for clients and their property. Sub contractors are independently selected by Andy to ensure that their skill level meets his standard of excellence. Many of these sub contractors have worked for Andy for more than ten years, and all of them have extensive experience in their field.
