"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"Isaac and team were incredible in getting a bunch of updating old and out-of-code plumbing work done on our tricky 100-year-old house. They took time to really dig in and assess the right game plan to make sure not only that all the plumbing and vents were done properly, but that they looked great given some would still be exposed / visible under our porch. The team was communicative and courteous. Our new plumbing is working like a charm. The tankless heater and smart shutoff are cranking. And everything passed on first inspection. The inspector even commented how clean and detailed it all looked. Would recommend SplashFix for any project, big or small."

"I had used them before and was very pleased so when the sump pump we bought at a local hardware store and installed ourselves did not empty the water from our basement, I called them. They were the only company of the 5 I called who came out the same day and looked at my problem. We have finally had so much rain that it over ran our french drains and started coming into the basement. They came on a Friday and had to order a bigger pump. They returned today, Monday, and are installing it the right way which we did not do. the noise from the old pump was so bad our daughter could not sleep. I am very happy with their service and they are the first company I will call with any future plumbing needs."
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.
Tankless water heaters are more expensive than those with a storage tank, but they come with some impressive benefits that most homeowners find worth the higher investment. Most importantly, they provide unlimited hot water, so you’ll never run out like you would with a storage tank. Tankless heaters are also more efficient, so comparing gallon-for-gallon, you’ll spend less on hot water with a tankless heater. Tankless water heaters are also smaller, require less maintenance, and tend to last longer than storage tank water heaters.
It usually takes a professional water heater installer between two and three hours to remove an existing water heater and install a new tank heater. However, it could take four to five hours if they have to work in a small utility closet or another tight area, like a crawl space. Tankless water heaters have a more complicated installation process, so they will take a bit longer. Additionally, a gas water heater requires a connection to a gas line, and that alone can add about an hour to the installation timeline compared to installing an electric water heater.
It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
In most municipalities, a license is not mandatory for water heater installation or replacement. However, we strongly recommend hiring a licensed plumber or water heater installer to handle the work. Licensed installers are far less likely to make a mistake during the installation, which means paying for the experience decreases your risk of a leak and other issues. You can use our state licensing tool to find out if a contractor you’re considering in your area holds a plumber’s license.
