Water Heater Repair
Most calls are one of these six. Tell us which sounds like yours and we will tell you what the repair usually involves.
On an electric unit, a failed heating element or thermostat is the usual cause. On gas, look at the pilot, thermocouple, or gas control valve. We test to find the failed part and tell you if the repair makes sense for the age of the unit.
A broken dip tube, a failed lower element, or sediment buildup shrinks how much hot water you get. Sediment is common here because Triangle water is moderately hard.
Shut off the water to the heater and call us. A leaking fitting, drain valve, or relief valve can be repaired. A leaking tank cannot, and in a townhome the water can reach a neighbor, so do not wait.
That is sediment baked onto the bottom of the tank. A flush can help on a younger unit. On a unit from the 2000s it often means the tank is near the end.
If you smell gas, leave and call your gas utility or 911 from outside. Otherwise, a pilot that keeps going out points to a thermocouple, a draft problem, or a gas control. We sort out which.
A bad thermostat or mixing issue changes temperature. Rusty hot water points to corrosion inside the tank, which is usually a replacement conversation.
Clear Answers
We test the unit, find the failed part, and tell you whether repair or replacement makes more sense. You get the real price before we start, in writing, and nothing begins until you approve it.
Most repairs are done on the visit. If the unit is leaking or at the end of its life, we replace it with a Bradford White tank, including the pan, expansion tank where needed, T&P valve, and venting.
We check for leaks, draft, and temperature, show you the shutoffs, and leave the paperwork for you, your HOA, or your property manager. Replacements are permitted and inspected where the town requires it.
Water Heaters in Morrisville
Most Morrisville homes were built from the 1990s into the 2010s, and many are townhomes and condos in communities such as Breckenridge, Kitts Creek, Providence Place, and the Weston area. The heater is usually in a tight closet or the garage, so we look at access, venting, clearances, and the drain path before we pick a unit. A leak in a shared-wall home can reach a neighbor, which is a reason to replace a builder-installed unit that is 10 or more years old on your schedule.
Two-story homes often have the heater in the attic, which needs a pan and drain line. If you are replacing, a standard tank is the simpler job. If you want a tankless water heater, we will tell you whether your gas and venting allow it. Our Cary tank water heater page covers the full replacement process, and financing is available.
Our shop is at 3460 Apex Pkwy in Apex, and we work Monday through Saturday, 7:00 to 18:00. Call or text (919) 679-1275, or book online. More about how we work in Morrisville.

Helpful Details
It depends on the failed part and the unit. We find the problem first and give you the real price in writing before we start. If repair does not make sense, we say so.
A standard tank replacement generally runs $2,000 to $4,000 installed, and tankless $4,000 to $6,000 installed. The exact number for your home comes in writing before any work starts.
That depends on your lease. Your landlord or property manager is usually responsible. We can give you a written diagnosis and price to send them, and we work with property managers on approvals.
It can. Gas units need proper venting and clearances, and a closet may not allow a taller or larger tank. We check before quoting and tell you what fits.
We pull permits and schedule inspections where the town requires them. We confirm before we start. We are licensed and insured in North Carolina.
