The Caldera Family

The Caldera Family

Caldera Construction’s success is based on the complete satisfaction of our clients, both during the construction process and after the project is complete.

Our unique approach to project management distinguishes us from other builders. We have assembled a construction team of skilled craftsmen, subcontractors and suppliers who work together, striving not just to meet our clients’ expectations but to exceed them whenever possible. We understand that customer satisfaction is a result of providing the finest quality finish at the most competitive pricing available.

We realize that the Owner’s vision of their home is not always contained within a set of blueprints. The thought and energy required to make the many decisions necessary, as well as the selection of plumbing fixtures, cabinetry, flooring, lighting fixtures, etc. can be overwhelming. Caldera Contruction takes the responsibility to meet frequently with Owners during the building process, providing them with our knowledge and expertise and enabling them to make choices consistent with their vision and in line with their budget.

We are proud of our many repeat customers. In our many years of building in Tuolumne and Calaveras Counties, we have yet to finish a project on less than friendly terms. In fact, many of our clients have become personal friends, as we worked with them during an exciting and important time in their lives.

We look forward to working with you on your next project and delivering a rewarding and memorable experience.
