Overview
Clean water at every tap — installed right in Shreveport
Many Shreveport homeowners buy bottled water instead of drinking from the tap — but that adds up fast. There's a better way. Mark Johnson & Sons Plumbing installs whole-house water filtration systems that deliver clean, crisp water from every faucet in your home.
Over a year or two, a home filtration system is significantly cheaper than continuing to buy bottled water — and far more convenient. We also install water softeners that address the hard-water mineral buildup common across Caddo Parish, protecting your appliances, fixtures, and plumbing for years to come.
From whole-house filters to point-of-use systems, we size and install the right solution for your Shreveport home. Professional installation ensures your system delivers clean, great-tasting water reliably — from the kitchen sink to the laundry room. Veteran-owned and family-operated since 1997, with flat-rate pricing on every job.
