Calahan Construction Services

For over 75 years the Calahan family name has been synonymous in Colorado with quality construction and customer satisfaction. We are proud of the level of excellence we deliver and commit to you that your project will not only be “on-time and on-budget” but will exceed your expectations. 

Rich, Don, and Gordon each have significant experience in the construction industry. From excavation to finish carpentry, and everything in between, the Calahans have done it. We put this extensive and in-depth background to work for you on each and every project.  

Experience counts and with Calahan you get a contractor who has experience completing projects of all sizes and scope. We are large enough and experienced enough to know what you and your project need, but not so large that you fail to get the time and attention you deserve. 

As an experienced Design-Builder we also have been active in delivering design-build projects for decades and strive to select teammembers that go beyond mere price competitiveness. Instead, we seek out partners who are recognized as both first-rate in their area of expertise, but also are proactive, attentive to detail, and recognize the importance of cooperation and teamwork. 

Utilizing teamwork and not guesswork Calahan Construction Services, together with its team members, is confident that we have assembled the most capable team you will encounter.

Experience where it counts coupled with enthusiasm and a sincere desire to please our customers will result in less uncertainty for you and your organization.
