"Our old water heater finally gave out, I was recommended to boston tank swap by a friend that just went through a leaking tank emergency as well. Dave was polite, clean, and took the time to explain everything without any upselling or pressure. You can tell they actually care about doing things right. The price was fair, and the whole experience was stress-free. Total time without hot water was less than 24 hours. It's nice to find an honest local plumber in Newton who still answers the phone and shows up when they say they will. Highly recommend!"

Do you offer same-day water heater installation in the Boston area?
Yes. Boston Tank Swap specializes in fast water heater replacement in Newton and across all of Greater Boston. When your water heater fails, we understand you need hot water restored quickly. We can often offer same-day or next-day service to get your hot water back up and running.
What are the signs my water heater needs to be replaced?
The most common warning signs include rusty or discolored hot water, rumbling or popping noises from the tank, water pooling around the base of the unit, inconsistent water temperature, and a unit that is more than 10 years old. If you notice any of these issues, it is worth having a licensed plumber inspect the system before a small problem turns into a major leak or flood.
How much does tankless water heater installation cost in Boston?
Tankless water heater installation in Boston is typically more expensive than standard tank replacement due to additional requirements like gas line upgrades, venting, and system configuration. Costs can vary significantly depending on your home and existing setup.
If you want a more accurate estimate for your home, you can check typical pricing ranges or send us a photo of your current system for a fast quote.
Should I switch from a tank water heater to a tankless system?
Tankless water heaters provide continuous hot water on demand, take up far less space, and can last 15 to 20 years compared to 8 to 12 years for a traditional tank. They are an excellent choice for Boston homes with high hot water demand or limited mechanical room space, and are also becoming a popular option for homeowners considering tankless installation in Cambridge and nearby towns throughout Greater Boston. However, they require adequate gas line sizing and proper venting. Our plumbers evaluate your home to determine whether a tankless upgrade is the right fit.
