Your Bay St. Louis plumbing & electrical team

Bay St. Louis wears its history in layers. Old Town's galleries, the Depot District and the streets off Beach Boulevard hold some of the Coast's most beloved historic homes — and Hancock County took Katrina's eye, so alongside the survivors stands a full generation of elevated, rebuilt homes. Two building traditions, one town, and each needs its own kind of care.

In the historic layer, we do the patient work: century-old drain systems with their gravity-and-hope engineering, wiring from before grounding was a concept, and the careful routing it takes to modernize without scarring original walls. In the rebuilt layer, the needs are different — elevated homes with long exposed utility runs beneath the floor, rebuild-era water heaters now hitting twenty years old, and panels that deserve a storm-season check given what this county already knows about weather.

We cover the bay side of Hancock County — Bay St. Louis, Waveland and out toward Kiln — with the 24/7 line that a storm-tested town appreciates having in the phone before it's needed.

Riley the Marlin — Reliance Mechanical mascot
🔧 Riley says

Bay St. Louis: if your house stands on piers, give the underside ten minutes a year with a flashlight. Pipes and hangers down there work hard and complain quietly.
