About Duke Custom Plumbing

Duke Custom Plumbing is proudly owned and operated by Caleb Duke, a 3rd generation plumber from Hayden, Idaho. Caleb is a dedicated tradesman who believes plumbing should be built to last, not just pass inspection.

Caleb prioritizes quality, efficiency, and long-term performance over rushing to complete a job. He approaches every project with craftsmanship in mind, taking the time to foresee potential obstacles and address them early in the process — when they’re easier and more cost-effective to solve. Clear communication and a strong understanding of the end goal allow him to deliver clean, reliable systems that serve homeowners and builders well for years to come.

With a strong appreciation for durable materials and proper installation, Caleb specializes in working with copper for longevity and craftsmanship, as well as cast iron for its durability and sound control benefits. Whether it’s new construction, a remodel, or detailed service work, he focuses on where value and quality truly matter.

As a small, owner-operated company, clients work directly with Caleb from start to finish — ensuring accountability, attention to detail, and pride in every install.
