Our Water Heater Repair Process

Straightforward Repair That Actually Works

First, we show up when we say we will and diagnose what’s actually wrong with your water heater. No guessing, no trying random fixes. We test the system, check all the components, and figure out the real source of the problem.

Then we explain what we found in plain English. You’ll know exactly what needs to be fixed, why it failed, and what it’s going to cost before we touch anything. No surprises, no upselling on stuff you don’t need.

After you give us the go-ahead, we fix it right. We use quality parts, follow proper procedures, and test everything to make sure your hot water is restored and reliable. You’ll know the job is done when you have consistent hot water flowing from every faucet in your house.

If your water heater is less than 8-10 years old and the repair cost is under half the price of replacement, repair usually makes sense. We look at the age, condition, and efficiency of your current unit. Signs that point toward replacement include multiple recent repairs, rusty water, significant leaks, or units over 12 years old. We’ll give you honest advice about which option saves you more money in the long run, not just what generates more revenue for us.
The most common issues we see are failed heating elements in electric units, pilot light problems in gas units, and sediment buildup from our local water conditions. New Bedford’s coastal environment can accelerate corrosion, especially in older homes. Thermostat failures and pressure relief valve issues are also frequent. Many problems develop gradually, so regular maintenance catches issues before they leave you without hot water completely.
Most repairs take 1-3 hours depending on the problem and whether we need to drain the tank. Simple fixes like thermostat replacement or pilot light issues can be done in under an hour. More complex repairs involving heating elements or internal components take longer. We carry common parts on our trucks, so we can usually complete the repair the same day. If we need to order a special part, we’ll let you know upfront and work around your schedule.
Yes, we service and repair all types of tankless water heaters including gas and electric models. Common tankless issues include mineral buildup, ignition problems, and error codes that indicate specific component failures. Tankless units require different diagnostic tools and expertise than traditional tanks, which is why many plumbers avoid them. Our technicians are trained on the major tankless brands and carry the specialized parts these systems need.
Absolutely. We understand that losing hot water isn’t something you can plan around, especially with families. We offer same-day service for water heater emergencies and work to respond as quickly as possible. Emergency situations include complete loss of hot water, significant leaks, or gas odors around gas units. Our emergency service focuses on getting your hot water restored safely and efficiently, even if it means working evenings or weekends.
First, turn off the power (electric) or gas supply to the unit for safety. Then shut off the water supply valve at the top of the tank. If there’s significant water, start removing anything that could be damaged. Small leaks from fittings can often be repaired, but leaks from the tank itself usually mean replacement. Don’t ignore even small leaks – they typically get worse and can cause serious water damage. Call us right away so we can assess whether it’s a simple fix or a more serious problem.
