"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."

"My hot water heater went out. I called several plumbers and was being quoted astronomical amounts along with quite a wait time to get to me. Brice was able to get the job done quickly (since no hot water sucks) and at a price I could live with. He was super funny and professional and made me feel like a friend had come over to help. I will always call him first for any of my plumbing needs"

"I had two plumbers visit my home to look at my waterheater and admit it was leaking and under warranty but offered no solutions. I looked on line for alternatives and reviewed tankless heaters;I requested a quote, and Steve Hosack responded within seconds! He made himself available faster than anyone else and had a new unit installed the next day. More importantly, he stopped the leak - actually flow of water immediately with a simple solution for which he expected nothing, saving me many dollars in wasted water. The other two "master plumbers" left the flow of water running. I purchased the tankless heater, as well as a new hot water tap, and had several minor repairs made by Steve and his crew. All work was professionally done. His crew was polite and efficient. I cannot recommend Hosack Plumbing and Excavation more highly!"

"MH Contracting is my number one choice for any type of plumbing work. First, their Veteran owned and that means a lot! Equally important is that they perform the highest quality work. They're, organized, responsive, respectful, professional, courteous, get the work completed the first time and they clean up after themselves. They truly take care of the customer. I first met them through a general contractor who signed on to do a large remodel project for me that included the complete rearranging of all second floor plumbing. They were impressive during the remodel and because of that, I've used them for all my plumbing work ever since! They're fantastic and won't disappoint!"

Affordable Plumbers questions, answered by experts

Always verify that your contractor holds a valid state license and carries adequate insurance to protect your property during MO storms. Hire professionals familiar with local codes rather than general metro standards. Your contractor must pull necessary permits for major plumbing projects, like water heater replacements. Choose experts experienced with older local infrastructure, such as cast iron drain lines and clay sewer laterals.

Helpful?

Homeowners must decide between trenchless or full excavation methods for sewer lateral repairs, which impacts yard disruption. You are responsible for ensuring your contractor pulls permits and schedules O'Fallon city inspections for significant plumbing upgrades. You must select your water heater type and fuel source. Finally, check your homeowner association rules to confirm exterior work and sump pump discharge locations comply with local regulations.

Helpful?

Slow drains in older O'Fallon neighborhoods indicate deteriorating sewer laterals or root intrusion, which quickly escalates to a full pipe collapse. Noticeable water pressure drops and rust-colored water point to severe internal pipe corrosion. Wet or sunken ground near your sewer cleanout means underground plumbing is actively leaking. Rumbling sounds from your water heater signal heavy sediment buildup that severely reduces the unit's lifespan.

Helpful?

After plumbing work in O'Fallon, confirm that all installations meet local code requirements and keep documentation for future reference. Inspect pipe insulation before winter to prevent freezing, and flush your water heater annually to manage mineral buildup. Test your sump pump each season, and if you use a private well, schedule annual water quality checks. Regularly checking for leaks supports long-term plumbing system health.

Helpful?

Routine plumbing maintenance in MO involves flushing your water heater twice a year to combat hard water sediment. You must winterize your system before November by disconnecting outdoor hoses and insulating exposed pipes in garages or crawl spaces. Test your sump pump annually before the spring storm season. Schedule a camera inspection of your sewer lateral to catch root intrusion early in clay soils.
