Hot Water Heater Repair Services

Complete Water Heater Solutions

We repair all types of water heaters – traditional tank units, tankless systems, gas, and electric models. From older units that just need the right part to newer systems with complex controls, we handle them all.

Our service includes thorough diagnostics, quality replacement parts, and testing to ensure everything works correctly. We also check for potential safety issues and let you know about any maintenance that could prevent future problems.

If your water heater is beyond repair, we’ll be straight with you about replacement options. But we’re not here to sell you a new unit if a repair will give you reliable hot water for years to come.

Age is the biggest factor. Most traditional water heaters last 8-12 years, while tankless units can go 15-20 years with proper maintenance. If your unit is approaching these ages and having frequent problems, replacement usually makes more sense than repeated repairs. However, if it’s relatively new and just has a specific component failure, repair is typically the right call. We’ll assess your specific situation and give you honest advice about which option makes the most financial sense.
Cold Massachusetts winters put extra strain on water heaters, leading to several common issues. Heating elements burn out more frequently due to increased demand. Sediment buildup happens faster in our hard water areas, reducing efficiency and causing strange noises. Gas water heaters often have pilot light or thermocouple problems during cold snaps. Tankless units can freeze if not properly maintained. We also see more pressure relief valve issues due to temperature fluctuations throughout the heating season.
Most water heater repairs take 1-3 hours depending on the problem. Simple fixes like replacing a heating element or thermostat usually take about an hour. More complex issues like gas valve replacement or extensive electrical troubleshooting can take 2-3 hours. We carry common parts on our trucks, so we can complete most repairs the same day. If we need to order a specific part, we’ll let you know upfront and work around your schedule for the follow-up visit.
We repair both tankless and traditional tank water heaters. Tankless units require different expertise since they have more complex controls and sensors, but our technicians are trained on all major brands and models. Common tankless repairs include descaling for mineral buildup, replacing flow sensors, fixing ignition problems, and addressing error codes. We also handle the annual maintenance that tankless units need to prevent problems. Whether you have a tank or tankless system, we have the tools and knowledge to get it working properly.
First, turn off the power (electric) or gas supply to prevent safety hazards. Then shut off the water supply to the unit – there’s usually a valve on the cold water line going into the top of the tank. If water is pooling, try to contain it with towels or a bucket to prevent damage to flooring. Don’t attempt to repair it yourself, as water heater leaks can indicate serious internal problems or pressure issues. Call us right away for emergency service, as leaks typically get worse quickly and can cause significant water damage to your home.
