Complete Water Heater Services

All Types of Water Heaters

We work on traditional tank water heaters, tankless units, and hybrid systems. Whether your problem is no hot water at all, inconsistent temperatures, strange noises, or visible leaks, we have the experience to handle it.

Many Lakeville homes have water heaters that are 10-15 years old, which means they’re entering the phase where repairs become more common. We can often extend the life of your current unit with the right repair, but we’ll also be honest if replacement is the smarter financial choice.

Our service includes thorough testing of all components, replacement of worn parts with quality materials, and recommendations for preventing future problems. We also offer maintenance through our Dempsey Comfort Club to help you avoid unexpected breakdowns.

If your water heater is less than 10 years old and the repair cost is under half the price of replacement, repair usually makes sense. Signs that point toward repair include inconsistent water temperature, minor leaks, or strange noises that started recently. However, if your unit is over 12 years old, requires frequent repairs, or has a major leak, replacement is often the better investment. We’ll assess your specific situation and give you honest guidance based on the condition of your unit and the cost of the needed repairs.
The most common causes are failed heating elements in electric units or pilot light issues in gas units. Electric water heaters have two heating elements, and when one fails, you might get some lukewarm water but not enough hot water for normal use. Gas units can have problems with the pilot light, thermocouple, or gas valve. Sometimes it’s as simple as a tripped circuit breaker for electric units. Other possibilities include a faulty thermostat or sediment buildup that’s interfering with heating. A proper diagnosis will identify the exact cause so we can fix it efficiently.
Most water heater repairs take 1-3 hours depending on the problem. Simple fixes like replacing a heating element or thermostat can often be completed in about an hour. More complex issues like replacing a gas valve or addressing multiple component failures might take 2-3 hours. If we need to order a specific part that’s not on our truck, we’ll let you know upfront and schedule a return visit. We carry the most common replacement parts so we can complete most repairs in a single visit without leaving you without hot water longer than necessary.
Those noises are usually caused by sediment buildup at the bottom of your tank. Over time, minerals from your water settle and harden at the bottom of the tank. When the heating element tries to heat through this layer, it causes the water to bubble up through the sediment, creating the popping or banging sounds. This is more common in areas with hard water and in older units that haven’t been maintained regularly. The solution typically involves flushing the tank to remove the sediment buildup. If left untreated, this can reduce your water heater’s efficiency and potentially damage the tank over time.
We repair both tankless and traditional tank water heaters. Tankless units have different common problems than tank units – they might have issues with mineral buildup in the heat exchanger, problems with the flow sensor, or error codes related to venting or gas supply. These units require specific diagnostic tools and knowledge of their electronic systems. We’re equipped to handle the most common tankless water heater problems including descaling, component replacement, and troubleshooting error codes. Whether you have a Rheem, Navien, Rinnai, or other brand, we can diagnose and repair the issue.
First, turn off the power to your water heater at the circuit breaker for electric units, or turn off the gas supply for gas units. Then shut off the water supply to the unit – there should be a valve on the cold water line going into the top of the tank. Small leaks from fittings or the temperature relief valve might be repairable, but leaks from the tank itself usually mean replacement is needed. Don’t ignore even small leaks because they can quickly become major problems that damage your home. Call us right away so we can assess whether it’s a simple fix or if you need emergency replacement service.
