Our Story
Built on Honesty. Grown on Trust.
Our goal is straightforward: make it easier to get help with leaks, drains, water heaters, sewer lines, and other plumbing problems.
We serve communities throughout Greater Los Angeles and Orange County. Explore our service and location pages for details, or call to confirm availability for your address.
From drain cleaning and water heater work to repiping and emergency repairs, we aim to explain the work clearly and provide practical options for your home.
What We Stand For
Our Core Values
Integrity First
We tell you exactly what's wrong, what it costs, and why — before we touch a wrench. No upselling, no scare tactics.
Excellence in Craft
Work is performed only by independent plumbing contractors holding current, active California CSLB licenses.
We Respect Your Home
Shoe covers on entry, drop cloths where we work, full cleanup when we leave. Your home is not a job site to us.
We Value Your Time
Showing up on time is non-negotiable. We give you a precise window and call 30 minutes before arrival.
Licensing
Our Licensed Partner Plumbers
Plumbing 405 is a referral service, not a licensed contractor. Plumbing work is performed by independent CSLB-licensed partners. The partner handles the quote, contract, permits, work, payment, and warranty. Contact Plumbing 405 to request service.
