New Water Heaters, Installed Right

Not every water heater can be saved, and not every home has the right one. These are the two ways we put a better heater in place.

Water Heater Installation in St. Augustine

A good installation starts before the heater arrives. We size the unit by how your household uses hot water, check the gas line, venting, or electrical circuit it needs, and plan the piping so it's easy to service later. Pricing is upfront, based on the unit and the work your space actually needs.

  • Gas lines, venting, and circuits checked
  • Tank, tankless, and heat pump models
  • Sized by first-hour rating or flow rate
  • Moving a heater out of a closet or attic
Water heater installation pricing and details

Water Heater Replacement in St. Augustine

A leaking tank can't be patched. Once the steel inside has corroded through, the only fix is a new heater, and we can often install a standard tank the same day or the next. You'll get a clear quote first, plus a code check of the venting, the gas or electrical supply, and the relief valve piping.

  • A puddle under the heater that keeps coming back
  • Rust-colored hot water
  • A tank more than 10 years old
  • Needing more hot water than the old tank delivers

How Much Does Water Heater Repair Cost in St. Augustine?

Most water heater repairs in St. Augustine typically land between $150 and $600. Where you fall in that range depends mostly on which part failed and whether the heater runs on gas or electricity. Every repair starts with a diagnosis and a clear, upfront price.

RepairTypical costWhat it usually means
Heating element or thermostat (electric)No hot water, or a short and lukewarm supply$150–$350Most common electric repair, usually same visit
Thermocouple or flame sensor (gas)Pilot lights but will not stay lit$150–$300Pilot lights but will not stay lit
Gas control valveValve will not open or regulate; weigh it against replacement on older tanks$300–$700Largest common repair; compare to replacement past 10 years
Anode rod replacementRotten-egg odor or a rod worn down to bare wire$150–$350Extends tank life when caught early
T&P relief valveDripping or discharging valve; water pressure checked too$150–$300Dripping or discharging valve; water pressure checked too
Dip tube replacementHot water runs out fast, plastic bits in aerators$150–$300Cracked tube mixing cold water into the hot supply
Drain valve replacementLeaking or stuck valve at the base of the tank$100–$250Drip at the bottom valve, often plastic on older tanks

Ranges are typical for these repairs; you get an exact quote before any work starts.

Factors That Change the Price

When a repair climbs toward the cost of a new heater on an older tank, we'll lay out both prices together, with no pressure either way. These are typical ranges, not quotes. Call (904) 335-6364 for your price.

Common Problems

Recognize These Water Heater Warning Signs?

If something seems off with your hot water, it usually comes down to one of these. Here are the problems we get called about most, and how we put a stop to each.

No Hot Water

A tripped high-limit switch, a failed gas valve, or a dead igniter can all look like the same symptom. Real diagnosis beats parts-swapping every time.

Same-day repair details

Water Around the Heater

Water on the floor can come from a loose fitting, a weeping drain valve, or a relief valve doing its job. Each one means something different, and we sort out which you have.

Leak repair

Rumbling Tank, Rusty Water

Rusty hot water can mean the anode rod is spent and the tank is starting to corrode. Catching it early can add years to the heater.

Maintenance & flushing

Aging Tank, Mounting Repairs

We size replacements by household demand and first-hour rating, not a guess, so the new heater keeps up with your busiest mornings from day one.

Replacement options

Tankless Unit Acting Up

We read the code, check the gas supply, venting, and flow sensor, and fix the actual cause instead of clearing the code and hoping.

Tankless water heater repair

Hot Water That Can't Keep Up

A growing family, a new soaking tub, or back-to-back showers can outrun a 40-gallon tank. A tankless unit heats water on demand, so it doesn't run out.

Emergency Water Heater Service

How We Handle a Water Heater Emergency

Speed matters when water is on the floor or the house has gone without hot water. This is the sequence our team runs through, from the moment your call comes in to the moment the hot water is back.

The call

Your Call, Our Priority

Our team answers your call right away, gathers key details (gas or electric, leaking or just cold, tank or tankless) and gets you on the schedule, often same-day. We'll walk you through shutting off the cold supply valve and the power or gas in the meantime.

Next

Prompt On-Site Visit

Right away, our fully equipped technician is on-site with everything needed to handle the problem in your property.

The visit

Diagnosis and Repair

On the first appointment, we test the full system. Our technician works through the burner, controls, venting, and tank and shows you exactly what failed and why.

After

Lasting Protection

An annual maintenance visit flushes out sediment and keeps efficiency up, and we send reminders when you're due. Staying ahead of the problem is how tanks outlast their expected lifespan.

Need Fast Help?

Don't wait. A leaking tank only gets worse, and water damage spreads fast.

What Local Homeowners Say

★★★★★
4.8 out of 5 · 150 reviews

"The relief valve pipe kept dripping and I didn't know if it was a big deal. The tech checked our water pressure and found it was way too high, then added an expansion tank and a pressure reducing valve. No more drips, and he showed me how to test the valve once a year."

"Our old tank started leaking all over the garage floor and I panicked. They told me exactly which valves to close while the truck was on the way, then replaced the whole unit that same day. They hauled the old tank off and didn't leave so much as a puddle behind."

LP

"Water started pouring out of the heater closet at 10 pm on a Saturday. They picked up right away, talked me through turning off the water and the breaker, and had a technician out first thing in the morning. New tank installed with a drain pan this time. Calm, fast, and fair."

Our Commitment

Why Neighbors Keep Calling Us Back

Good water heater service comes down to doing the small things right. These are the commitments that earn us repeat customers and referrals year after year.

Small Checks, Big Savings

Most tank failures are slow, and most of them can be pushed back. A yearly flush clears sediment, an anode rod check stops corrosion before it reaches the steel, and a quick relief valve test confirms the most important safety part works. For tankless units, descaling does the same job.

People Who Know Water Heaters

Hands-on experience is the real benchmark for water heater work. Every technician on our team is a seasoned pro across gas, electric, tankless, and heat pump units, so your home is serviced according to proven best practices.

Right-Sized, Code-Compliant Work

Water heater sizing is simple math, and we show ours. Our team walks you through the sizing and installs it to local code, permits included where required.

Common Questions

Your Questions, Answered

Most water heater repairs typically run between $150 and $600, depending on the part. Thermostats, heating elements, thermocouples, and flame sensors sit at the lower end, while a gas control valve can reach $700. If the tank itself is leaking, repair is off the table, and a replacement typically runs $1,100 to $2,800 installed for a standard tank or $2,800 to $5,500 for tankless. We diagnose the problem first and give you a clear, upfront price before any work begins.
If the heater is under about 8 years old and the problem is a part, such as an element, thermostat, thermocouple, or valve, repair usually makes sense. If water is leaking from the tank body, the hot water runs rusty, or a tank unit is past 10 to 12 years old, replacement is the smarter investment, because a corroded tank cannot be patched. Our technicians walk you through both numbers honestly so you can decide with real information.
We offer same-day and emergency water heater service throughout the area. Our trucks carry the most common parts (heating elements, thermostats, thermocouples, flame sensors, relief valves, and drain valves), so most repairs are finished in a single visit. When a tank does need replacing, standard sizes can often be installed the same day or the next.
For many households, yes. Tankless units heat water on demand, so you do not run out during back-to-back showers, they take up little space, and they often last 20 years or more compared with roughly 8 to 12 for a tank. They cost more to install, especially when a gas line or venting has to be upgraded, and they need periodic descaling in hard water. We size the unit to your peak demand in gallons per minute and give you honest numbers before recommending one.
Yes. Our technicians work on all major residential and commercial brands and every common type: gas and electric tank heaters, tankless units, heat pump (hybrid) water heaters, and larger commercial systems. We carry universal parts on the truck and can source brand-specific components quickly when needed.
