Welcome to Koski Construction:
We recognize you have choices when it comes to hiring a contractor for your remodel or construction project, so let us share some reasons you will be happy with our team.
We are lifetime locals here in the Aspen Valley. We have a great network of subcontractors, people whom we trust and that have excellent quality. Beyond that, however, we do much of the work ourselves. We work onsite and supervise the project from start to finish and ensure that things get done right and that our clients are satisfied. We are very good at communication, and have no problem with answering questions or discussing options via phone or email or in person.
In years past we have built many high end custom homes in the Roaring Fork Valley. We have remodeled many condominiums and luxury homes from Aspen to Snowmass Village to Basalt and Carbondale. We have the skill set for larger projects but have chosen to focus on smaller scale completely custom remodels. The Aspen Valley is served by many fine contractors, and many firms have extensive offices with full-time managerial staff to manage large expansive projects. We have distilled our operation so that we can serve the Roaring Fork Valley’s need for a personal, trustworthy, high quality, hands on contracting company for the smaller spectrum of construction projects in the valley.
Feel free to browse our Portfolio Page above. Also please check our References Page, we would love to add you to our list of satisfied homeowners.
Sincerely,
Steven Koski
