“The master in the art of living makes little distinction between his work and his play, his labor and his leisure, his mind and his body, his information and his recreation, his love and his religion. He hardly knows which is which. He simply pursues his vision of excellence at whatever he does, leaving others to decide whether he is working or playing. To him he’s always doing both.”
– James Michener

I want to give a hearty recommendation and thanks to Mason Cawley and Cimarron Design & Build. They repaired a long standing problem that I've had at my house with water leaks and resultant damage going back over 12 years. (I've had this issue addressed several times by my original builder and other contractors to no avail). Mason and his team expertly repaired the damage and then applied new innovative solutions to finally fix the root of the problem. Never will you find a more competent, polite, considerate, timely and reasonable builder. Thanks to Mason and his team.

Mason and his team were great to work with! My remodeling job was complete within the time frame that they promised and the work was impeccable.

- Alison Kothmann

A quality company with caring owners who are committed to excellence in everything they do!

We have had the pleasure of knowing Mason Cawley since he relocated to Kauai with his family in 2013. We were fortunate to have had the opportunity to work with him (and wife Cheri) throughout the process of designing what now used to be their island home. Our working relationship with Mason continued after completion of his own home as he began working as an electrical contractor and project manager on several of our other projects.

Mason brings with him a wealth of knowledge working in the construction industry. Mason exhibited the ability and know- how to coordinate & schedule materials, manage labor, and keep the project moving on schedule and within the target budget.

Mason brings to the table a strong drive to succeed, ability to problem solve challenges, and the confidence that comes only from real world experience.

- Nathan Teixeira and Conrad Schmidt

I found Mason to be extremely knowledgeable in the entire residential construction industry. His input in design, functionality, and cost effective solutions for my project were second to none.

I also found Mason to be extremely proficient in time management, punctuality, labor management and quality control. His attention to detail is superb.

His positive attitude, all around construction knowledge, and get it done work ethic would be an asset to anyone considering working with Mason.
