Your water heater works around the clock, usually without a thank-you. We keep it running with expert repairs, right-sized replacements, and maintenance that adds years to the tank.
A dead water heater doesn't wait, and neither should your plumber. With technicians based around the area, we provide fast, reliable service and hands-on care from people who know the local water, the local codes, and the way these heaters actually fail.
A new heater is a ten-year decision. We help you choose the right type and size, then install it cleanly with every connection tested.
New heaters fail early when they're undersized, poorly vented, or missing an expansion tank. We handle the details that get skipped: proper draft, relief valve piping, drain pans, and pressure checks. You'll know the full installed price before we start.
When a heater is past its prime, we help you pick the right replacement: another tank, a tankless unit, or a heat pump model, sized by first-hour rating or flow rate instead of a guess. We haul the old unit away, bring the new install up to current code, and give you an upfront price first.
For most Pleasanton homeowners, a water heater repair usually comes in somewhere between $150 and $600. The part that failed drives the price: an element or thermocouple is a quick, inexpensive fix, while a gas control valve is a bigger job. You'll get an upfront quote from Pleasanton Water Heater before we touch a single part.

Ranges are typical for these repairs; you get an exact quote before any work starts.
On older tanks we always compare the repair against a replacement, so you can make the call with real numbers. These are typical ranges, not quotes. Call (925) 222-4903 for your price.

When the heater is on but the water stays cold, the fault is almost always one specific component. We find it and fix it fast.
Same-day repair detailsSome leaks are a simple fix at a fitting or drain valve. Others come from the tank itself, which can't be repaired. We tell you honestly which kind you're looking at.
Leak repairRusty 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.
Water heater maintenanceWe 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.
Water heater replacementTankless heaters need their heat exchangers flushed in hard water. Skip it, and the unit overheats, throws codes, and eventually fails.
Tankless water heater repairWe size and install tankless units carefully, with the right gas line, venting, and a descaling setup, so they deliver steady hot water for years.
Go tanklessA proper repair includes the details: a draft test on gas units, a relief valve check, a look at the anode rod, and a temperature check at the tap before we leave.
We treat your budget like our own: fix what's fixable, replace what isn't, and size every new heater to your household instead of the biggest tank on the truck.
When the tank quits the night before a busy day, hours matter. Our local technicians roll out same-day with stocked trucks, ready to repair on the spot.
Our plumbers work on water heaters every day (gas and electric tanks, tankless units, and heat pump models) and keep up with new equipment as it comes out. Your home gets a specialist, not a generalist with a parts catalog.
Most people don't think about their heater until the shower turns cold. Our plumbers think about them all day. Our team has seen nearly every failure a tank or tankless unit can throw, and that experience shapes how we approach each job, from the first diagnostic to the final temperature check.
Knowing the area is half the job. We've learned which neighborhoods have hard water, which older homes need their venting brought up to code, and what inspectors here look for on permits, and we put that knowledge to work so each job is done right the first time.

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.
You call (925) 222-4903. A real person picks up, assesses your situation, and sets up fast service for your home. If you smell gas, leave the house and call your gas utility first, then call us.
Your plumber shows up ready to work, not just to look. The common failure parts ride on every truck, so the visit moves straight from diagnosis into repair.
The fault is identified: thermocouple, element, gas valve, relief valve, or the tank itself. Right away, we complete the repair on the spot whenever parts allow, or quote the replacement with real numbers if the tank is done.
Yearly maintenance checks the anode rod before the tank starts to rust, and we'll remind you when it's time. Staying ahead of the problem is how tanks outlast their expected lifespan.
"The pilot on our gas water heater kept going out, and I was relighting it every other day. The technician found a worn thermocouple and replaced it on the spot. It has stayed lit ever since, and he explained what to watch for going forward."
"When our electric tank died we decided to try a heat pump water heater. They walked us through the space and airflow it needs, pointed us toward the utility rebate information, and installed it in a day. Our electric bill dropped noticeably."
"Water started pouring out of the heater closet at 10 pm on a Saturday. They answered on the second ring, 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."
Good plumbing service comes down to doing the small things right. These are the commitments that earn us repeat customers and referrals year after year.
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.
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.
