Tell us about your unit and we'll call you right back.
Most standard units last 8–12 years. Once leaks, rust, or constant repairs start, replacing is typically more cost-effective than another service call. Here's what to watch for.
Standard tank water heaters have an expected lifespan of 8–12 years. If yours is reaching or past that range, you're likely spending more maintaining an aging unit than a replacement would cost.
A water heater that leaks repeatedly or is actively rusting is a sign of internal tank corrosion that repairs can't fix. In Charleston's slab-foundation homes, leaks spread quickly and damage floors and cabinetry.
If you're scheduling repairs every season, the cumulative cost often exceeds what a new unit would run. A single replacement eliminates the cycle of surprise service calls and restores reliability.
Older water heaters eventually outlive their parts supply. When replacement parts become unavailable or prohibitively expensive, a new installation is the only reliable path forward.
Older tank water heaters lose efficiency as sediment builds up, forcing them to use more energy to heat the same amount of water. A high-efficiency tankless or hybrid system can significantly cut monthly costs.
Many homeowners replace a working but aging unit proactively — switching to a tankless or hybrid system for continuous hot water, reduced energy use, and long-term savings before the old unit fails.
Each home is different, and each type of water heater offers distinct benefits. We walk you through the right choice based on your family size, hot water demand, and available connections.
Tank units provide steady hot water at a lower upfront cost and are the right choice for many homes. We supply and install standard tank water heaters from trusted manufacturers, including expansion tanks and new shut-off valves as needed.
Tankless systems reduce energy usage and provide continuous hot water on demand. We install high-efficiency tankless units sized correctly for your home's hot water demand and available gas or electrical connections.
Hybrid systems offer efficiency upgrades without major plumbing changes — ideal for many Lowcountry homes. And if you have a leaking or unsafe unit, call us during business hours and we'll prioritize getting a technician to you the same day.
We want you to feel secure, informed, and confident about one of the most important systems in your home — and we back that up with every installation.
We share what we would recommend for our own homes. Our technicians don't push unnecessary upgrades — they help you make practical decisions based on your usage, budget, and how long you plan to stay in your home.

"Our technicians were on time, efficient, hard-working, and thorough — spread drop cloths on floors and even vacuumed our carpet when completed. And the most polite work crew we have ever had. It was a HOT DAY in the attic, but they endured to replace our HVAC! Big THANK YOU to Mike, Zach, Sterling, & Pedro!!"
"Kyle was very pleasant and knowledgeable. He did not rush through the job. He was very upfront and took the time to explain the situation and made suggestions. It was a pleasure to have him in our home."
"I just had the very best experience with a plumbing service call. Kevin Hathaway with PLUMB PRO+ performed an excellent job repairing my water heater. He kept me posted on his progress, left his work area spotless, and carried himself in a professional manner. Thank you Kevin!"
