You should hire a licensed plumber to check your water heater for annual maintenance, leaks, or repairs. For gas units, your local gas utility provider will often send a technician to inspect gas lines or relight pilot lights.
If so, you're probably wondering how much a maintenance visit will cost you. The cost of water heater maintenance ranges from $75 to $300+, depending on the following factors: What the plumber checks during a maintenance visit. Whether you choose a single visit or an annual maintenance plan.
If your water heater is leaking, call a plumber as soon as possible to have it inspected and potentially replaced.
Traditional tank water heaters last 8 to 12 years, while tankless models typically last 15 to 20 years. Lifespans vary greatly depending on water quality, unit design, and whether you perform regular maintenance like flushing the tank and checking the anode rod.
The average cost of a plumbing inspection is $100 to $200 for a basic visual inspection, $300 to $1,100 for a camera or video inspection, or $400 to $1,300 for a combination of the two. Plumbing inspections typically cover fixtures, water and sewer lines, water heaters, toilets, pumps, drains, and appliances.
A: Traditional tank water heaters usually last 8–12 years, while tankless units often last 15–20+ years. Q: Should I replace my water heater if it's over 10 years old? A: Often yes. Even if it still works, the risk of leaks and sudden failure increases significantly after 10 years.
Signs a water heater is going bad include leaks, rusty or metallic-smelling water, unusual rumbling/popping noises, and inconsistent temperatures (or lack of hot water). If your tank is over 10–15 years old, has frequent repairs, or causes higher energy bills, it is likely nearing failure and may need replacement.
When searching for the most reliable water heater, professional plumbers consistently recommend A.O. Smith, Bradford White, and Rheem. For long-term tank durability and a "set-it-and-forget-it" experience, A.O. Smith and Bradford White are top choices. If you prioritize high-tech smart features and energy efficiency, Rheem is a market leader.
A new 40-gallon water heater costs between $𝟒𝟎𝟎 and $𝟐,𝟎𝟎𝟎 for the unit alone, depending on the fuel type, brand, and efficiency. When factoring in professional installation, the total typically ranges from $𝟖𝟎𝟎 to $𝟑,𝟎𝟎𝟎.
If the cost of repairs exceeds 50% of the cost of buying a new water heater, replacement is likely the smarter decision, especially if your water heater is older. Older or less efficient models may result in higher utility bills. Upgrading to a newer, more energy-efficient unit can save you money over time.
Water leaks are perhaps the most common type of water heater issue you'll face. Any water heater will start to leak eventually, as by nature water will eventually corrode your tank and create microscopic cracks or fractures. However, this isn't always a sign that your tank is what's leaking.
Yes, licensed plumbers are typically the go-to professionals to call for water heater repair. They handle: Installation and replacement. Leak detection and repair.
If the project is as simple as replacing an old water heater with a new one, a handyman can likely do it with no trouble. However, converting a gas water heater to an electric one or putting in specific wiring and framing for the water heater will likely require the skill set of a licensed professional.
If your water heater isn't working, first ensure the power or gas is safely supplied and check for visible leaks. Then, check either the electrical panel or the pilot light depending on the type of unit you have.
Professional installation costs to replace a water heater
The more hours of electrical, carpentry and plumbing work that are required for your installation (for example, installing new electric, water or gas lines or drywall), the higher your total water heater replacement cost.
Based on the manufacturer's suggested service life, the average life expectancy of a water heater is about 8 to 12 years. That varies with the location and design of the unit, quality of installation, maintenance schedule and water quality.
Banging, clicking, rapid switching noises, or unusual pump sounds may indicate the system is struggling to maintain pressure normally. While several components can cause noise, a failing tank is a common source when it is paired with inconsistent water pressure.
A 40-gallon tank water heater installation costs $700 to $2,300, with an average cost of $1,650. Prices vary based on energy source and installation complexity. The national average cost to install a 40-gallon tank water heater ranges from $700 to $2,300.
There isn't a single "number 1" model, as the ideal water heater depends on your home's setup, but top-rated brands dominating the market include Rheem (best overall tank/tankless) and A.O. Smith (best for durability and commercial-grade units).
The Home Depot offers traditional water heater tanks and modern tankless units, both powered by either gas or electricity. Depending on your selection, the average cost for standard tank installation is generally between $1,600 to $2,400. Tankless installation can range from $2,400 to $5,400.
Bradford White water heaters are widely regarded as some of the most durable on the market. They come with an array of well-thought-out features that enable them to stand up to all kinds of wear and tear that results from regular use. Overall, they have a longer service life than Rheem water heaters.
If you are looking to properly decommission, drain, or dismantle an old water heater for replacement, the process involves safely shutting off the power and water, completely draining the tank, and carefully disconnecting the plumbing.
Tankless water heaters are the longest-lasting, averaging 20+ years, while the Rheem Marathon leads tank-style heaters with a lifetime warranty. Standard steel-tank models fail within 8–12 years, so maximizing longevity requires either choosing a premium model, a tankless unit, or maintaining standard units.
