“Brandon did his usual good job. Showed up on time and completed installation of new 50 gallon water heater. We had discussed replacing our “ancient hot water heater” during Brandon’s previous visit. Brendan gave us an estimate at that time and at the conclusion of today’s installation, our bill was for that exact amount That’s the previous service call as we had been quoted. The water heater is working flawlessly and we remain very pleased with Mark Johnson Plumbing service as usual.”

Good to Know

Frequently Asked Questions

Filter by topic, then tap a question. A real person answers every call, 24/7.

Do you offer 24/7 emergency service?

Yes. Our dispatch office is staffed Monday through Saturday, 7am to 7pm, and a licensed technician is always on-call 24/7 for emergencies. Every call is answered by a real person — no answering machines, no overseas call centers. Whether it's a burst pipe at 2am or a no-cool AC on a Sunday, someone picks up.

What areas do you serve?

We cover 20+ cities across North Louisiana — Lincoln, Ouachita, and the surrounding parishes. From Ruston out to Monroe, West Monroe, Bastrop, and Minden, we dispatch crews with same-day availability in most cities. Not sure whether we serve your ZIP code? Call (318) 319-0220 and we'll confirm.

How fast is your emergency response time?

For true emergencies — burst pipes, sewer backups, gas leaks, water heater or AC failures — we target on-site response within 60 to 90 minutes across Ruston and surrounding areas. Response for outlying service areas can run 2 to 3 hours depending on crew location. We communicate ETAs in real time.

How does your pricing work — and do you offer financing?

We quote flat-rate pricing upfront, before any work begins — no hourly surprises. Payment is collected on completion, never before, with an itemized invoice. We accept all major credit cards, debit, and ACH/check, and offer financing through our partners for larger projects like water heaters, repipes, and HVAC installs.

Do you offer warranties on your work?

Yes. All labor comes with a 1-year workmanship warranty standard, and parts carry the manufacturer's warranty (typically 5 to 10 years depending on the product). Major installs like water heaters, repipes, and HVAC systems carry extended warranties — often up to 10 years on parts and 2 years on labor.

Are your technicians licensed and background-checked?

Every technician on our roster is W-2, background-checked, and Louisiana-licensed — never a subcontractor. We're a veteran-owned, family-operated company that's held North Louisiana's trust for 30 years, licensed, bonded, and fully insured across plumbing, heating, and cooling.
