Here's How We Handle Your Repair

First, we diagnose the actual problem. No guessing, no throwing parts at it hoping something works. We test the system, check the components, and figure out what’s really going on.

Then we explain what we found in plain English. You’ll know whether it makes sense to repair or replace, what the repair involves, and what it costs before we start any work.

Once you give us the go-ahead, we fix it right the first time. We use quality parts, clean up after ourselves, and make sure everything works properly before we leave. You’ll get hot water back and know exactly what to expect going forward.

What's Included in Our Service

Every service call starts with honest diagnosis. We’ll tell you if it’s a simple fix or if you’re looking at replacement time. No upselling, no scare tactics—just straight information about your options.

Our repairs cover everything from heating elements and thermostats to gas valves and venting issues. We handle both tank and tankless water heater repair, plus we can upgrade you to a more efficient system if that makes sense for your situation.

Plymouth County homes deal with hard water, cold winters, and aging plumbing systems. We know how these factors affect your water heater and plan our repairs accordingly. That’s why our fixes last instead of failing again in six months.

Age is the biggest factor. Most tank 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 problems, replacement often makes more sense than expensive repairs. Other signs pointing toward replacement include rust in the hot water, frequent repairs, or significantly higher energy bills. However, newer units with single-component failures are usually worth repairing. We’ll assess your specific situation and give you honest advice about which direction makes financial sense.
Hard water is the biggest culprit in our area. Mineral buildup shortens the life of heating elements, clogs pipes, and causes tanks to fail prematurely. Cold winters also stress the system since it has to work harder to heat incoming water. Sediment buildup in the tank bottom is extremely common here, which reduces efficiency and can cause the tank to overheat. Regular maintenance helps, but most homeowners don’t think about their water heater until it stops working. Age-related component failure is also common in Plymouth County due to our older housing stock.
Simple repairs like replacing a heating element or thermostat usually take 1-2 hours. More complex issues involving gas valves, venting problems, or multiple component failures can take 3-4 hours. We carry common parts on our trucks, so most repairs can be completed the same day. If we need to special-order a part, we’ll let you know upfront and work with you on temporary solutions if possible. Emergency repairs get priority scheduling, and we’ll give you a realistic timeframe when we schedule your appointment.
We repair both tank and tankless water heaters. Tankless units have different common problems—usually related to mineral buildup in the heat exchanger, ignition issues, or venting problems. These systems require specialized knowledge and tools, which our technicians have. Tankless repairs can be more complex than tank repairs, but they’re often worth doing since these units last longer overall. We also handle the annual maintenance that tankless systems need to prevent problems. Whether you have gas or electric, tank or tankless, we can diagnose and repair the issue.
Yes, we provide emergency water heater repair service for Plymouth County residents. We understand that losing hot water isn’t something you can wait a week to fix, especially during cold weather. Emergency calls get priority scheduling, and we’ll work to get your hot water restored as quickly as possible. Keep in mind that emergency service may involve additional fees, but we’ll discuss all costs upfront. If the problem occurs outside normal business hours, we’ll assess whether it’s something that needs immediate attention or can wait until the next business day without causing damage to your home.
First, turn off the power to your water heater—flip the breaker for electric units or turn the gas valve to “off” for gas units. Then shut off the water supply using the valve on top of the unit. If water is actively leaking, try to contain it with towels or buckets to prevent damage to your floors or belongings. Don’t attempt to repair a leaking tank yourself. Tank leaks usually mean the unit needs replacement, while leaks from connections or valves might be repairable. Call us right away for leaking water heaters since continued leaking can cause significant water damage to your home.
