About Us

Bringing Over Eight Decades of Proven Quality, Knowledge, and Experience to the Front Range

Ownership of Calahan Construction Services has passed down through four generations of the Calahan family. As a locally owned and operated business, we bring a client-focused small business approach to projects and deliver results that surpass even the industry’s most prominent companies.

A Trusted Partner in the Front Range Since 1937

As a full-service general contractor, we know experience counts. For over eight decades, Calahan Construction has successfully completed countless commercial projects—large and small—for clients throughout the Front Range.

We bring expertise, experience, quality, integrity, and value to every project we take on. One detail that sets us apart from the competition is our superior customer service. We are a large enough company to take on any size project, but small enough to ensure you receive the attention and collaborative opportunities that deliver the highest quality results.

We want to be a comprehensive partner for our clients. Calahan Construction provides free pre-construction consulting, estimates, and budgeting consultations that help us understand your needs. We work with you to set a budget and timeline while also learning your business requirements from these meetings.

We are a proud Small Business Enterprise certified company that holds board member status at numerous organizations. We were awarded the Master Builder Award from Star Metal Buildings and are certified builders and partners with several vendors.
