Best Tankless Water Heater Repair in Saint Louis MO

We had a confusing bill situation that was ultimately resolved. An exterior spigot installed last year leaked when we turned it on for the season. We were erroneously charged for the repair, but have since sorted it out with the company. I recommend reaching out directly if you have any questions or issues.
So far so good on the repair, as well.

Had a new laundry sink installed and an outside faucet replaced.  Glenn did a great job on the install.  Proposal was quick and fairly priced.

Honest, experienced and convenient!  Jim showed up on schedule, provided an explanation of what the service will require and the cost.  He had all the materials needed on his truck and how long it would take.  He did a great job!  I would highly recommend him to friends and family!

Performance Plumbing just put in a new bathroom for us in our finished basement. They did everything: plumbing, electric, drywall, and flooring. They even put in a closet! The guys were professional and efficient, and the price was right.  I love my new bathroom!

Great service and professionalism. Eric was very courteous and efficient. Would have given five stars but I thought $175 for half an hour's work was maybe a but steep.

I have used Royal Flush for all of my plumbing issues after using them for the first time nearly 4 years ago.  I have used them for both new installation and items that needed to be fixed.  I think it was a sense of trust and confidence after that first time that sold me 100% on this company.  Before using Royal Flush, I had used several other plumbers but never ever had a feeling of trust and confidence concerning either their competence or issues of cost.  With Royal Flush, I no longer worry about either of those.   It is just nice to simply call a tradesman and not feel I have to question anything.

While I couldn't use them for my plumbing, they walked me through exactly what I needed to do to fix my issue, a video of how to do so, aswell as scams to avoid. While I can't use them for work in Jefferson County, I will definitely be recommending them to family and friends solely on that transparency!

Called to have a heating igniter replaced. Told them this was the issue on the phone since I pulled it myself and noticed it was broken. Came out fixed it but it cost me $580!!! Before calling I found the part online it was a $75 part. When I called they quoted me $95 service fee they charged me $95 and $485 just for the part. The technician Just had to plug and screw it in. Crazy expensive, would not recommend. I feel like I got ....

I needed a natural gas line extended from my basement to my kitchen (for a stove install) - I reasoned that I could do that myself with enough YouTube video-watching, but being natural gas, I decided it best to hand it off to the pros. Price came in a little higher than I expected so I talked it out with them, and they gave me some options to lower the price.

Day of, the guys came out on-time, were perfectly pleasant. Bonus: not a single plumber buttcrack was seen that day. The job took them a bit longer than even they expected, which was fine, and they explained why - since it was a lump-sum job and not hourly, I certainly didn't mind if they took their time to do it right.

When it came time to do the stove install, they were very careful not to cause any scratches to either the floor or the stainless-steel stove. They threw all trash in their own toolbox to take with them instead of tossing in my trash can (being in a consultant/service industry, I appreciate little things like that).

All-told, I was completely happy with the price, the people, and the result - can't think of anything that I would've expected differently. I'd recommend them.

They install my AC and was defective get paid came several time failed to fix it and now refusing to answer my call or take care of it
