G2 Construction

Fair, Transparent, & Personable Approach

At G2, construction runs in our veins. With our family in the construction industry for decades, it was only natural for us to build a company focused on home remodel and general contracting. One that serves our home; the Colorado Front Range.

G2 Construction is a company for you. It’s a company that is dedicated to creating a transparent process for every construction job. When we stepped out on a limb to start G2, we had our future clients and team in mind.

Our first goal was to create a company that provided the most personable, fair, and transparent approach to remodels and general contracting projects. A company that valued problem solving and refused to let any hurdles stand in the way of flawless completion.

Our second goal was to provide the greatest service on the Colorado Front Range by building the best team of skilled and loyal employees. Taking care of our team and creating a warm, supportive work culture, enabled us to put together a fully dedicated group of professionals ready to do the work.

Life-Long Passion. Skill. Transparency. Problem-Solving. Authenticity. Care. Support. These are the foundation of G2 Construction.
