A civil construction company.

Our Story

Coal Creek Constructors Inc. was founded in Boulder, Colorado in 2013 after the Front Range Flood ravaged fourteen counties in the region. Our president and CEO, Bill Sisko, wanted to help bring normality back to those affected by the disaster by providing excavation and restoration in both the commercial and private sectors.

Bill gained excavation, construction, and bridge building experience in his home state of Vermont shortly after obtaining his business degree. While operating in New England he gained industry experience by performing hurricane flood restoration, ice disaster mitigation, and other major natural disaster clean ups such as Superstorm Sandy in New Jersey.

After establishing ourselves in Colorado, our expertise rapidly expanded to include rebuilding and restoring residential bridges and roadways, executing site development, commercial and residential excavation, large-scale earthmoving, utility work, large-scale hardscaping, specialized rock drilling, structural concrete and more. We have the knowledge and competence to execute our projects following our core values of timeliness, integrity, and efficiency. We hold ourselves to the highest standards and regard our team and clients as family.

Coal Creek Constructors Inc. has experienced operators that know how to safely and efficiently complete your projects. We operate in the upmost professional manner, and believe proper communication, organization, and capability are the keys to operating a successful business. Coal Creek under-promises and over-delivers, with customer satisfaction being our top priority. Let us impress you with our professionalism, premium performance delivery, and competitive pricing today.
