"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"

"Main plumbing line in our warehouse was clogged. Could not use either bathroom. Ducky drains was fast and efficient and had everything back up and running in no time! I highly recommend this company. I personally would not use anyone else."

"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 absolutely top notch! I cannot nor would not think of hiring anybody else for any of my needs at my home. My wife and I wanted to make our basement into a master suite with a large master bathroom and large walk in closet. We contacted Home Advisor which then put us in touch with several companies. MH Contracting was without fail, the best choice. After meeting with all of the companies and comparing bids, we knew that Mike and MH Contracting was the way to go. We had grand plans but were not sure that we could afford to do everything at once. We needed to start with adding an egress window to the basement. Their quote was right within our budget. Mike helped take our basement from an in home office to a wonderful paradise. My wife and I must have changed our plans at least 10 times during the process. Each time Mike and Scott said ������������������������ no problem������������������������. We went from planning a 65 sq ft bathroom to over a 220 sq ft bathroom with an additional walk in closet at another 120 sq ft. This does not even include the master bedroom. From the beautiful walk in shower, 72������������������������ soaker tub, tv mounted above the tub to the heated floors, everything has turned out perfectly. Both Mike and Scott are very scrupulous about every aspect of what they do. Then we decided to take down a wall between our twin������������������������s bedrooms to make one large room. You can������������������������t even tell where the wall was. Their drywall work is amazing. They showed up on time, worked a full day and cleaned up every single day they were here. We trusted them from the beginning. We gave them the alarm code and access to the house exclusively. They even worked while our 13yr old twins were home over spring break. Never a trust issue and that������������������������s hard to come by now a days. Our project took about 2 months from start to finish. I������������������������ve already had Mike and crew out to my father in laws house for some electrical work and to my daughter������������������������s house to work up a quote for all new windows and some much needed concrete repair issues. I can������������������������t wait for our next project to be planned."

Affordable Plumbers questions, answered by experts

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?

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?

In O'Fallon, recurring clogs, low water pressure, visible pipe corrosion, or mineral deposits on fixtures can signal poor past plumbing work. Foundation settling due to clay soil may cause pipe misalignment, while freeze-thaw cycles can lead to joint leaks. If permits were skipped or incompatible materials were used, or if water quality issues persist, have a professional evaluate the system for possible rework.

Helpful?

In O'Fallon, plumbing projects often interact with electrical, HVAC, and structural systems. For example, installing a new water heater or sump pump may require electrical updates, while pipe leaks can impact HVAC performance and air quality. Sewer line repairs might involve foundation work, and bathroom renovations could affect walls or flooring. Always coordinate with utility providers before starting major plumbing changes.

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.
