Since 1985, Kirkwood Plumbing has been performing fast, affordable, and high-quality plumbing services to homes and businesses in St. Louis and beyond. Our licensed and certified plumbers believe that quality workmanship and clear, honest communication makes all the difference, which is why you can count on us to always deliver honest recommendations, unmatched service, and 5-star customer care. No job is too big or small for our skilled plumbers, so whether you need seamless installations, remodels, repairs, or replacements, our team can help. From designing and installing your dream kitchen to replacing an outdated water heater and everything in between, you can count on our plumbers to exceed your expectations at every turn.

"I cannot recommend Kirkwood Plumbing/Mr. Rooter anymore after my experience. I called because the copper pipe on my water heater (I believe the temperature and pressure valve) would leak when we took a shower. The plumber they sent was very nice and told me that he discovered the issue was a failed PRV. He said that when multiple faucets ran at the same time, the pressure was reduced and that meant the PRV failed. I even asked if this would fix the leaking copper pipe on the water heater and he said yes. He quoted me $785 to replace and although that seemed a bit high, I agreed. He left and got the part, came back and replaced it. Well, when he was done with that replacement he said he “looked closer at the water heater” and actually my expansion tank had ALSO failed and was mostly water when it should be air. Only he just looked and discovered this after doing $800 of work??? And oh the pipe between the water tank and expansion tank had been leaking at some point but was not now. He recommended a new expansion tank and replacing that pipe section. He quoted me an additional almost $700 to do that job!!! And told me that the leaking from the water heater would not be fixed until he also did this. He said he thought the PRV had failed causing the expansion tank to fail and he would need to go out to get a new expansion tank too. He apologized for not realizing that sooner he said. This is completely unacceptable. At this point I’m essentially held hostage by your company to complete the job as the already $785 would not have fixed the leak as told. I told the plumber it’s disappointing because if I knew it was a much bigger issue I would have likely gotten other quotes, and in addition, I don’t feel like I could really trust him or the company at this point. I agreed to do the expansion tank for an additional $271 and would wait for the pipe to be fixed since it was not currently leaking and only showed signs of leaking in the past. I will never again use this company and will make sure to spread my experience. While doing some jobs you may discover additional issues, this wasn’t the case here. All he had to do was test the expansion tank (which is apparently a common failure for temperature and pressure valve issues) BEFORE starting the job and give me a quote for the actual fix. Not do an expensive job saying it will fix the issue and then saying that it wouldn’t fix it after. He even said it was his mistake. Again, he was very polite, but it is completely unacceptable to essentially hold your customers hostage halfway through a job saying the first fix wouldn’t even fix the problem, after doing it. I’ve since learned that the expansion tank should have immediately been tested for this issue and that it was rather backward to check the PRV first, as the expansion tank is often the culprit in these cases and that considering he said that it was mostly water rather than air, it would have been easy to diagnose. As for the PRV, with the water off it maintained 60psi and dropped 10-20 points when two faucets were on, which I have since learned may also be normal operation and not needing replaced. I’m not sure if this is how all customers are treated or just women customers. My advice is do not use this company. They respond quickly but will gouge you and not provide upfront pricing. He could have saved himself two trips out (making this take much longer) as well as given me upfront pricing had he just “looked at the water heater closer” the first time- you know the apparatus I called them out for in the first place. Offering “upfront pricing” is clearly not something they do. I now feel like I paid $785 for a service I did not need when I really just needed a new expansion tank and could have paid for that/fixed that without replacing the PRV and checked to see if that fixed the problem. I even told him I did not have pressure issues. Beware for unneeded services at a high cost and not adequately diagnosing the problem or even investigating until AFTER finishing unnecessary work."

Tiger Plumbing, Heating, Air Conditioning, & Electrical Services takes pride in being your preferred local plumbers, electricians, and HVAC technicians! In fact, more homeowners in the St. Louis Metro East & Central Illinois communities we serve, say they would call us again before any other plumbing, electrical, heating, or air conditioning service!

"My technician Keith was great. Friendly and super informative. Also too a quick look at the entire drainage system and gave my an idea of where problems will pop up the future without preventative measures (my home was built in the 50s and while the previous owners took really good care of the house nothing has been gutted and replaced yet)."

Boiler installation services FAQs

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
