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 From designing and installing your dream kitchen to replacing an outdated water heater and everything in between, you can count on our plumbers to exceed your expectations at every turn.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."

Simply reach out and we will dispatch a technician immediately to provide a quote and solve your problem!
"Only rating 1 because it doesn't go lower. Had a new unit installed end of Sept 24. First time power goes out on 11/5, no electricity. When tri state sells you a product, they pitch their amazing customer service with all these guarnatees of knowing when your unit is out before you know and having someone there within 24 hours etc. Well, the first call we make we are told it will be the end of Nov to get someone out to look at it. 3 weeks. Nobody shows up. Then we get a call that says "your appointment on Dec 12 has been canceled and the earliest we can get to you is Jan 16th. This is 2.5 months wait to get service to fix a nearly $20k unit, that is upcharged because of the excellent service. You can't get anyone to answer your call. you wait on hold for 20 minutes, then have to leave a voicemail in which you will not get called back. Based on my experience, find someone else and pay less. Even if the service is bad, which it can't be worse than this, you save money! @kohler"

Gas fireplace repair services FAQs
Fixing a gas leak costs about $45 to $150 per hour for a plumber or gas line specialist. The job’s overall cost will vary depending on the location of the leak. A leaky junction or connection behind the stove or dryer will likely cost about $120 to $170. But for a leak that requires a gas fitter or plumber to excavate a pipe in the yard, the cost could rise to $1,500 to $5,000. Keep in mind that gas leaks are very serious issues, so don’t hesitate to contact a plumber or gas line specialist immediately.
The cost to install a fireplace is $2,440 on average. This cost can range from $150 to $8,000 or more, depending on the type of fireplace, the materials used, and the size.
Electric fireplaces cost around $1,000 to install, and mostly only require wiring installation. Installing a wood fireplace from scratch could cost upwards of $10,000, depending on the foundation needed to support the weight of the fireplace. In addition, gas fireplaces can cost between $2,500 and $10,000.
The cost to remodel your fireplace is $1,200 on average. This cost can range from $400 to $2,000, depending on the extent of work needed.
If you add a hearth to your fireplace, you can expect to pay between $3 and $200 per square foot. However, if you're refacing your fireplace, the price tag will depend on your chosen materials. If choosing tile, you can pay between $1 and $50 per square foot, depending on the design. Stone is a more expensive material, averaging between $60 and $70 per square foot.
Yes, it can be worth installing a gas fireplace, depending on your home heating needs. The cost to install a gas fireplace can be much lower than the cost to install a comparable wood-burning fireplace. The convenience of starting a fire with the flip of a switch and turning it off just as quickly makes a gas fireplace a big time saver over starting and maintaining a wood-fueled fire. A gas fireplace also does not require ash cleanup or frequent chimney cleaning to remove creosote and other buildup that can lead to chimney fires. Gas fireplaces burn and heat much more cleanly than wood fireplaces.
A gas fireplace insert costs about $3,600 to install, on average. The cost to install a gas log insert ranges from about $700 to $6,500, depending on the size, type of insert, how it works, and heating needs. Gas fireplaces need electrical and gas lines installed properly, so hiring a pro is recommended rather than trying to DIY installation.
