Residential and Commercial Water Heater Installation
Replacing a water heater is a decision before it is a job: size, type, fuel, and where it goes. Our shop is at 3460 Apex Pkwy, so we know Apex houses and how they were built. We install Bradford White tank units and Navien and Rinnai tankless units, and give you the real price before we start.

Water Heater Installation and Replacement
Most installation calls come down to one of these six situations. Tell us which is yours and we will walk you through the choices.
When the tank has failed, we measure the space, check the gas or electric supply, and give you written options. Ask about current water heater offers when you call. You choose the unit, and the old one is drained and hauled away.
A tank that is 10 years old or more is on borrowed time. Replacing it on your schedule means you pick the unit, not a flooded garage. It also avoids the rush job on a bad day.
Tank units cost less up front and install simply. Tankless units last 20+ years, never run out, and save floor space, but they cost more and may need a larger gas line and new venting. For the full story, see [tankless water heaters](/tankless-water-heaters).
Most homes should replace like for like, because switching fuel means new lines or a new circuit. Size depends on how many people and fixtures draw at once. We size it to your household, not to the biggest unit on the truck.
Many Apex subdivision homes put the heater in an attic, garage, or crawlspace. Attic installs need a pan and drain line. Crawlspace units sit in damp air. We plan the pan, drain, access, and venting before we begin.
A growing family, a new tub, or a remodel can outgrow a 40-gallon tank. We look at larger tanks, two-unit setups, and tankless, and tell you which fits the house.
Clear Answers
We check the location, fuel, venting, and what you actually use. You get the real price before we start, and nothing happens until you approve it.
We drain the old unit, haul it away, and set the new one with a pan where needed, a new expansion tank where needed, a new T&P valve, and fresh connections. We check venting and the gas line size for the BTU rating.
We test heat-up, venting, and the relief valve, and show you the shutoffs. The work is permitted and inspected where the town requires it.
Water Heaters in Apex
Apex homes built from the 1990s on, in places like Haddon Hall, Abbington, Woodcreek, and Salem Village, often have the heater in an attic or garage. Older homes near downtown Salem Street may have it in a crawlspace. Each location sets what the install needs: a pan and drain for the attic, protected access in the crawlspace, and proper venting for gas units. Electric units are common where there is no gas service. Read the Wake County cost guide for what drives the job.
Many builder-grade heaters from the 2010s boom are now reaching the end of their life. Planning the replacement beats waiting for a leak. If tankless is on your mind, we will tell you honestly whether your gas line and venting can support it before you spend the money. Ask about financing if you want to spread the cost out.
Our shop is at 3460 Apex Pkwy, and we work Monday through Saturday, 7:00 to 18:00. Call or text (919) 679-1275, or book online. If your heater is already leaking, see emergency plumber. More about how we work in Apex.
Commercial Water Heater Installation
Restaurants along Williams Street and Salem Street, salons, offices, and churches need more hot water than a home unit gives. We install commercial-capacity systems as well as home heaters.
Restaurants and salons draw hard at peak hours. We size larger tank units to the real demand and check that the gas line and venting can carry them.
Banks of tankless units give continuous hot water and can be staged so a single failure does not leave you without. We plan the gas, venting, and water connections together.
For churches, offices, and long pipe runs, a recirculation loop puts hot water at the tap fast and cuts wasted water. We design and install the loop with the heater.
Helpful Details
A standard tank replacement typically runs $2,000 to $4,000 installed, and tankless typically runs $4,000 to $6,000 installed. The exact number for your home comes in writing before any work starts. Our Wake County cost guide explains what moves it.
If it is 10 or more years old, showing rust, rumbling, or moisture at the base, yes. Tank units usually last 10 to 15 years, longer with annual service. Planning ahead means you choose the unit and the day, instead of dealing with a flood.
It can be. Tankless units last 20+ years and never run out of hot water, but they cost more up front, and a conversion may need a larger gas line and new venting. We tell you whether your house is a good fit. Full details are on our tankless water heaters page.
Yes. We drain and haul away the old unit. Replacements are permitted and inspected where the town requires it, and we handle that so you do not have to.
Usually yes, if it can be done properly. Attic units need a pan and drain line. Crawlspace units need good access and protection from damp. If the location is a problem, we tell you before we start.
Call or text (919) 679-1275, or book online. We work Monday through Saturday, 7:00 to 18:00. Ask about the labor warranty and current water heater offers when you call.
