"I had them install two outside spigots and two internal shutter valves to those spigots. I also requested a bid on a new water heater and some shut off valves under my sink. They were prompt in their response to get me a quote. The price was fair and the work was done quickly, effectively and professionally. They are great to work with very responsive, fair priced and easy to do business with I would certainly use them for all my plumbing needs."

"Terrific is an understatement! After being told by my HVAC company that they could not install a new hot water heater for 3 days, TJ at Metro Plumbing went above and beyond to make sure we had hot water before guests arrived the following day. He tracked down the unit we wanted, came to the house on a Saturday and he and his associate worked in tight quarters to the get the unit installed. It is no wonder he has been in business for 15 years! If you want a job done well at a fair price, I highly recommend KC Metro Plumbing! Thank you, TJ!"

"Tom discussed what I would want in a heater and why he recommended the brand he did. They arranged the appointment and arrived on time. The gentlemen installing the unit were friendly, polite, and informative. They cleaned up after themselves and ensured I understood what they did and that everything worked before they left."

"Erick and his crew took out our garbage disposal, dishwasher, and replaced the oven hood in the kitchen. They replaced the old wooden baseboards (which had mold) and toilets in the bathroom. They also installed a water softener and replaced our water heater. Erick and his workmen were extremely kind and polite, being perfect gentlemen while in our condo. While installing the new toilet when they noticed an issue that could cause water to leak to the unit below our Erick sought to remedy the situation so that would not occur and his crew worked late to fix the crack and install the new toilet. Erick was flexible and was willing to incorporate any changes we needed. When the work was completed, Erick only charged us the amount of his original quote. We plan to contact Arcadia in the future for additional work we need to have done."

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.
Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
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.
The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350.
