Overview
Better Water for Monroe Homes — Without the Bottled-Water Bill
Many Monroe-area homeowners buy cases of bottled water week after week because they are not confident in their tap water. It is a habit that adds up fast — and it is completely avoidable. A professionally installed whole-house water filtration system delivers the same clean, crisp taste as bottled water from every faucet, shower, and appliance in your home, at a fraction of the ongoing cost.
Mark Johnson & Sons Plumbing has been installing water filtration and treatment systems across Ouachita Parish since 1997. We assess your home's water quality, recommend the right combination of filtration and softening equipment for Monroe's water conditions, and install everything correctly the first time. Whether your concern is taste, odor, chlorine, sediment, or mineral buildup on fixtures, we have a solution sized for your household.
Pairing a whole-house filter with a water softener is especially effective in North Louisiana, where mineral content can cause scale buildup on water heaters, fixtures, and appliances — shortening their lifespan and raising your energy costs. Our technicians explain every option in plain language and provide upfront flat-rate pricing before any work begins.
