Plumbing in Monroe

Monroe sits in Ouachita Parish, and the plumbing in this city reflects a mix of older neighborhoods and newer growth. Older streets often have aging service lines. Newer parts of the city have different materials, but the same need for a plumber who can get there the same day when a line fails.

Mark Johnson & Sons Plumbing runs a Monroe warehouse. It is a crew and parts facility, not a walk-in counter, so there is no front desk to meet you there. Use the call button at the top of this page, and a technician comes to you. The Ruston headquarters is the location set up for visitors.

Plumbing services we offer in Monroe

A plumber in Monroe, LA can handle more than a single clogged sink. The work we dispatch from the Monroe warehouse includes:

What is distinctive about Monroe work is the warehouse itself. It holds crews and parts for Monroe, West Monroe, Sterlington, and Swartz, but it is not set up as a public counter. The Ruston headquarters remains the place for visitors. Homes here also call often about Slab Leak Repair and Water Leak Detection, not only a single clogged sink. Water heaters and fixtures collect mineral scale, which our guide to hard water in Monroe explains in more detail. Older laterals in clay or cast iron are a common reason drains that were fine for years suddenly slow down or back up.

What Monroe homes actually call about

In older Monroe streets, a slow floor drain or a sewer odor often points to a lateral that needs a camera, not another bottle of cleaner. In rental properties with heavy fixture use, repeating clogs and worn water heaters are common. West Monroe is served by the same Monroe crews, and that work is covered on the West Monroe plumber page.

If more than one drain is slow at once, or a toilet rises when the washer runs, start with drain and sewer service rather than a single fixture part.
