Kevin and Matt were amazing! From the initial call, to the inspection, And then within less than a day from that the installation of my water heater they were friendly, respectful of my house, and work efficiently to get my water heater installed. Very impressed with this company and would highly recommend!

I can’t say enough good things about R.A. Guinner Plumbing in St. Louis. We had been dealing with low water pressure for the entire 3 years we’ve lived in our home and never realized there was an actual problem. Our house was fully inspected before purchase, and no one caught the issue. I sent one picture to Kevin, and he immediately identified the problem — a DIY low-pressure valve installed on a high-pressure line instead of a standard main water shutoff valve, which was restricting flow throughout the house. That level of knowledge and experience alone was impressive. They were able to come out to Imperial Missouri the same day, confirmed the diagnosis, and went above and beyond to fix the issue. They even took care of extra services to replace our expansion tank and pressure spring to help us out, without hesitation. The professionalism, honesty, and attention to detail were outstanding. Now our water pressure is amazing, and our house finally works the way it should have from day one. If you’re looking for a reliable, knowledgeable, and trustworthy plumber in the St. Louis area, I highly recommend R.A. Guinner Plumbing. We couldn’t be more impressed or grateful.

Called due to upstairs shower leaking into kitchen, spoke with Nick, he said they could assess, but might pass off to a bigger company. When I said I wasn't familiar with bigger companies, it was a simple thanks and have a nice day almost like I was an inconvenience.

I cannot recommend this company enough. I tried 3 other places and was finally referred to RA Guinner. I called Kevin at 2 pm on a Friday and he had some at my house within the hour. They did great work. Will only use them for any plumbing needs in the future.

Our water heater went out in the middle of a huge cold front. We were scammed by our home warranty and were desperate to get it fixed since we have a newborn. My husband attempted to find the problem and ended up discovering we had a warranty on the water heater. The water heater manufacturer connected us to RA Guinner and we are so happy they did. We expressed that it was an emergency due to the fact we had our newborn at home and it had been almost 5 days without hot water. They sent the sweetest employee over as soon as possible and he was able to diagnose the problem and fix it within the hour. Aside from the urgency to come help us, we are thrilled that this company respects families and has a team that is warm, friendly and helpful.
