About
CPI Plumbing & Heating began with a simple promise: treat every customer like family and every home like our own. From our roots in Mount Vernon, WA, we’ve grown into one of the most trusted names in plumbing and heating across the North Sound because we never lose sight of what matters most: people. For decades, CPI has been part of the fabric of our community. We’ve fixed pipes in century-old homes, installed heating systems for new families, and answered emergency calls in the middle of the night because when your comfort is on the line, you need someone you can trust.
