Overview
Trusted water heater service across Shreveport & Caddo Parish
A malfunctioning water heater can bring your whole day to a stop. Whether you have a leaking tank, no hot water, or you're ready to upgrade to an energy-saving tankless system, Mark Johnson & Sons Plumbing has Shreveport homeowners covered with fast, reliable service.
We service and install every major brand of tank and tankless water heater across Caddo Parish. Our technicians help you choose the right size and type for your home, then install it correctly the first time — so you get dependable hot water for years to come.
Not sure whether to repair or replace? We'll give you an honest assessment. If your unit is under 8–10 years old and the repair is minor, repair usually makes sense. Older units with leaks, rust, or repeated problems are often cheaper to replace. Tankless systems are an excellent fit for many Shreveport homes — they provide endless hot water on demand, take up less space, and often last 20+ years with proper maintenance. Flat-rate pricing, always upfront.
