A diagnostics-first plumbing company.
Herndon McFarland Plumbing has served Addison and the North Dallas metro since 1995. We built our reputation on a simple idea: find the real problem before anyone picks up a tool. That means non-invasive leak detection, careful plumbing testing, and clear, honest documentation that homeowners and insurance adjusters can rely on.
Our team is licensed under the Texas State Board of Plumbing Examiners (Lic. #RMP35786), background-checked, and drug-tested. Every install is backed by a one-year labor guarantee, and every diagnosis is explained in plain language, with no exaggeration and no pressure.
Why North Texas trusts us
- Family owned and locally based in Addison since 1995
- Insurance-ready cause-of-loss reporting trusted by adjusters
- Master-plumber-led crews, fully licensed, bonded, and insured
- Same-day appointments across the North Dallas metro when possible
