"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)."

"Anytime Heating and cooling was awesome. I called to see if they could come out to see what was going on with our furnace. It was the coldest day of the year! Our home is over a 100 years old and the furnace was once a coal furnace but converted into gas. It needed a part replaced. No other HVAC company had any experience working on our type of unit, but Anytime knew exactly what to do! We are so grateful for them and will continue using them as long as we own our home. I would definitely recommend them for your HVAC needs!"

"Installed new AC and heater unit in April 2023. Had used Garrett prior as I found them reasonably priced. After the install, numerous safety/code violations were found when the unit was inspected. Among them were not adding a safety drip pan under the furnace, not installing a coil condensate drain correctly, running a flexible gas line into the furnace cabinet (a code violation), not terminating the electric correctly (a code violation), leaving exposed wires on the AC unit outside. The new owner claims it's not his responsibility to fix these issues. I'd steer away and go with someone that wants to back up their work (sorry, it's your work if you buy the company). Update as of 01/15/2025 Response to review and company response Jan 2025. Company DID NOT come out or even reach out to me regarding this. Tape and duct work repairs? When did you come to my house? Shows how dishonest this company is. Stay clear. Only excuses from this company (for example. we bought our business in 2024, not our problem!)"

Plumbing and heating 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.
The average cost to unclog a drain is around $200, with prices ranging between $110 and $800, depending on the type of drain and the extent of the clog. Hiring a professional to snake the toilet or sink will usually cost between $110 and $275, a bathtub or shower typically costs around $225, and a main line clog can cost between $100 and $800 based on the severity of the clog and how far beyond the access point the clog sits. Since the labor involved varies, most plumbers will charge an hourly rate for drain cleaning.
