Overview
Every plumbing job in West Monroe, one local crew
Mark Johnson & Sons Plumbing has served North Louisiana since 1997. Veteran-owned and family-operated by Mark, Michael, and John, we have built our reputation on one principle: Old-Fashioned Service with Modern Technology. West Monroe and Ouachita Parish homeowners trust us because a real person answers the phone at any hour and our technicians show up on time, every time.
We are BBB A+ accredited since 2012 and have earned more than 300 five-star reviews with a 4.9-star average rating. Our flat-rate pricing means you know the full cost before any work begins — no surprises and no after-hours surcharges. Every technician arrives in a fully stocked truck ready to solve most plumbing problems in a single visit.
Our crews run out of our Monroe warehouse, just across the Ouachita River, so we reach West Monroe quickly. Whether you need a routine repair, a full pipe replacement, or an urgent middle-of-the-night call, our team is ready. We handle plumbing only — every technician is trained, licensed, and focused on one trade so they can do it right the first time.
