"I had my full home repiped as I switched from electric to forced hot water heating. Fred was courteous, communicative, and timely in making the repairs. We ran into quite a few snafus and he took them in stride. His quote was MUCH lower (about half the price) of the original quote we got. Definitely recommend."

"I was impressed with his knowledge and his ability to explain his thoughts to me as we were reviewing what needed to be done to install a replacement propane water heater He scheduled the project right away and came in the time frame designated, finish the work and also did extra functions that had to be done to allow the equipment to get into my basement. He followed up to make sure everything was working well and offered to come back in a day or two if I needed assistance. His billing was easy and professional. We are hoping to have him back again next year to do some HVAC work."

"Response time was excellent. He'll return to rough in the new water supply and install new fixtures as soon as we are ready. Has done work for us for a few years, always consistent quality and professionalism. Rescued us from previous drunk plumber who left in middle of a job."

"Woke up on a Tuesday morning, just happened to go downstairs to get some dog food. Squish, squish under my feet! Open the garage door, water everywhere with a hole in the side of my water heater, water pouring out! Turned off water, grabbed my phone and texted Richard at NE Renovations (this was before 7:30 in the morning). Got an immediate reply saying they could be there later that same morning, and told me what to do in the meantime. Jim (a wonderful plummer at NE Renovations), called around to find the water heater we needed, as it vents outside. By mid-afternoon, we were back up and running. Jim even helped clean up some of the water in the garage! I've written about these guys before and continue to have only great experiences. I only talked to them by phone that day and once again, trusted them to enter my home while the rest of us were at work. Pretty much no interruption to a busy day. I don't think that could have happened with another provider. These guys are top notch and really know their stuff. Couldn't recommend them more highly!"

Water Heaters FAQs, answered by experts

While possible, professional assistance is recommended to ensure compliance with local regulations and avoidance of avoidable risks.

If your system is not vented properly, you could experience what’s called backdrafting. Backdrafting is when your ventilation system isn’t working as it should, and instead of releasing gases outside, they get trapped inside your home. 

Gas and propane water heaters create a few types of combustion gases, but the most dangerous is carbon monoxide. If there’s too much build-up of these gases inside your home, it can lead to carbon monoxide poisoning.

If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.

Unless you have previous plumbing experience or extensive experience with water heaters, you should avoid replacing your electric water heater yourself. This process involves disconnecting wiring and parts from the old water heater and reinstalling them onto the new one, among other difficult tasks. This job is best left to the pros to make sure that everything is connected correctly to avoid serious leaks or malfunctions.

Newer models are packed with newer technologies that decrease energy consumption and increase output, giving you more bang for your buck in more bills than one. 

If you’re trying to decide whether you want to repair or replace your new heater, consider factors like your utility bills, repair costs, and even your carbon footprint to help you decide whether it makes sense to buy a new one instead.
