"Kirkwood Plumbing was very responsive, sending a highly qualified technician within 24-hours. He did an incredible job replacing old cast stacks and vents to our 2nd floor bath. The further comment that I would make is they are not cheap. I'm still trying to reconcile their cost for a 7-8 hour job, but the results couldn't be better."

"I cannot emphasize enough how Ducky Drains will be my choice anytime I have an issue with my plumbing. Mike was super knowledgable, quick and helpful! He’s growing his business the correct way, on his integrity. I’ve been raked over the coals by other plumbers. If you are in need of help with any plumbing problems, he’s your guy!"

"My Pro was absolutely fantastic. Not only did he take care of my clogged sink, his "sink side manner" displayed respect, knowledge, and professionalism. He also left me with information on how to clear my drain naturally. Zoom Drain is now my go to company for plumbing."

"The people on the phone and the workers that worked at my house were fantastic. Damien and Ernest were the installer's top rate people. Jack, their license plumber was polite and funny. The only person we didn't care for was Keith He only stopped by to look at what was going on. He was a little rude to my wife and Made her feel Like she was second class in her own home. We Were very shocked by that. We would definitely recommend Jacuzzi to our friends."

FAQs for plumbing projects in O Fallon, MO

It depends on the severity of the leak. Minor leaks may not require immediate attention and can be scheduled during regular business hours. However, if the leak is causing significant water damage or you can't control the flow of water, it's best to call an emergency plumber right away. Addressing serious leaks promptly can prevent structural damage and mold growth, potentially saving you money on extensive repairs later.

A journeyperson plumber is a licensed professional with a state-issued permit who installs and repairs piping for water and heating systems under the supervision of a master plumber. They have completed extensive training and amassed significant experience leading teams, drafting blueprints, and designing comprehensive plumbing installations. Their proven expertise ensures that they can handle both routine repairs and complex projects with precision.
