Trusted Plumbers.
CopperLine has served Arizona homeowners with honest pricing, skilled craftsmanship, and a phone that's always answered.
18+
Years Serving AZ
Built on Honesty.
Grown on Trust.
CopperLine Plumbing Co. was founded by Ray Castillo, a third-generation plumber who grew up watching his grandfather fix pipes across Phoenix neighborhoods. Ray started the company with one truck, a commitment to showing up on time, and a simple rule: quote it straight, fix it right, leave the place cleaner than you found it.
Today, CopperLine operates a fleet of fully-stocked service vehicles across the Greater Phoenix metro. We've completed thousands of jobs for homeowners, landlords, and contractors — earning a strong reputation for reliability and fair pricing.
We're still family-run. Ray's daughter Mia leads operations, and every technician on our team is background-checked, drug-tested, and holds an active Arizona plumbing license. We hire slow, train hard, and stand behind every job with a 1-year workmanship warranty.

What We Stand For.
Upfront Pricing
You get a written quote before any work begins. The price you approve is the price you pay — no line items added after the fact.
On-Time, Every Time
We give you a 2-hour arrival window and call 30 minutes before we arrive. Your time matters as much as ours.
Fully Licensed & Insured
Every technician carries active Arizona plumbing certification and is covered under our company insurance. Documentation available on request.
1-Year Warranty
We warranty our workmanship for a full year. If something we fixed fails due to our work, we come back at no charge.
Background-Checked Team
Every CopperLine technician passes a thorough background check and drug test before their first day on the job.
Community First
We sponsor local youth sports leagues and support Arizona water conservation initiatives — because this community is our home too.
