"The service from the response from the initial call to the finished work was the best. It was the first time I used them and they are now my plumber and have recommended them to others"
"Kirkwood Plumbing is represented by very capable plumbers, does its work without surprises, and has a very strong commitment to customer satisfaction. For those reasons I give it an A rating. Below is the story. I needed to have the upper stack of the toilet replaced and have a new toilet installed. Of the 3 companies I called, only Kirkwood Plumbing sent a master plumber, a plus. Paul was very observant and identified the least intrusive manner I was chip to complete the tasks, which in an old home, was not simple. Although not the least expensive bid, I accepted it based on the confidence Paul inspired. That was a very good decision. Greg arrived on time at the appointment date and immediately went to work. He is a capable plumber who worked very hard and efficiently, a plus. He had a great manner with his assistant and it was a pleasure to observe them working together. Greg was determined to leave me with running water and a functional toilet by the time he had to leave, and that was much appreciated. To that end, however, he did not take the time to go back to get the correct saw to cut through the cabinet and wall and thus created sufficient dust particles to saturate the air. Nor did he go back to get the correct shut off valve so he didn't install one. Those were negatives. After he left, I noticed that I could no longer open the faucets in the bathroom so I got in touch with Kirkwood plumbing. They immediately rescheduled a return visit, a positive. Greg attended to the issues that remained but couldn't repair the faucet problem. Although he was convinced that he did not cause this problem, he called Jason in to take over, another plus. Jason is a very thoughtful, methodical plumber who calmly and efficiently repaired the problem. I don't know if he thought this issue was a separate or related problem but he refused any additional payment that I offered, another plus."
"He was extremely professional and knowledgable and was able to fix an issue that three other plumbers could not. He was also very reasonably priced for the work. I highly recommend him and one hire again."
"I can t say enough great things about Hosack Plumbing and Excavation. They just completed replacing the main water line from our home to the street. Their work is excellent, they completely explain what they are doing and make you feel very comfortable and when the work is completed everything is neat and clean and back to its original state. Their pricing was very fair and they were professional and friendly."
"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!"
"Don was very professional and affordable. He finished my water pressure regulator and new faucet in under an hour. My only complaint is that the drain for my sink he worked on has been leaking for over a week and he hasn't come back out to look at it. Aside from that, I'm very happy with Don's work and will hire him for more projects in the future."
"I called Hosack on a Thursday morning because my water heater had died, and because of their great Angi reviews. They had a plumber, Kent, at my house before noon. Kent was fantastic ... great work, extremely knowledgeable, and VERY customer oriented. I'm extremely happy with Hosack's responsiveness, quality of work and attention to detail. Going forward, they (and I hope Kent!) are my plumbers of choice. I highly recommend!"
Affordable Plumbers questions, answered by experts
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?
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?
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, urgent plumbing issues like burst pipes, sewer backups, or water heater failures require immediate attention, especially during cold snaps or heavy rainfall. Projects such as fixture upgrades or bathroom remodels can typically be planned for milder seasons like spring or fall. Always consider local weather, the risk of water damage, and contractor availability when prioritizing repairs or improvements.
