"They took out my old shower and installed a new one. They came out quickly and installed the shower kit and door within 5 days, despite heavy rains that week. Customer service was great. They were professional and came out again when we asked to adjust the shower water temp to get hotter. Even though they had to add additional framing for the shower door, they only charged my for whatever was quoted in the beginning. Overall, I was very satisfied and would work with them again."

Water Heaters FAQs, answered by experts

Storage, tankless, heat pumps, and solar water heaters each suit specific space constraints, usage needs, and efficiency preferences.

Electric water heaters typically last 10 to 20 years, though proper maintenance can extend their lifespan. If your unit is over a decade old and showing signs of inefficiency—such as higher energy bills, frequent repairs, or leaks—replacement is a smart investment. Tankless models last over 20 years, which can make them a longer-lasting alternative to traditional tank water heaters.

Excessive pressure (above 80 psi) puts too much stress on plumbing pipes, joints, and fixtures. This can lead to leaks and burst pipes. Plus, it shortens the lifespan of appliances, can waste water, and can raise your utility bills. High water pressure might feel like a gift, but it’s actually a silent threat to plumbing.

You don’t have to replace expansion tanks at the same time as your hot water heater. You may be able to go six to 12 years or more before needing to replace your expansion tank. At $150 to $450, hot water heater expansion tanks are usually much more affordable than the cost of hot water tanks themselves, which average about $1,190.

The good news is that most home warranty plans cover hot water heaters, regardless of whether you have a tank or a tankless model. Your hot water heater should be covered by your home warranty because it's considered an essential home appliance.
