Plumbing reviews in O'Fallon, Illinois

This commendation is written by Maria Martin. We are extremely happy and thankful that our garbage disposal and toilet are back in operation. Adin did an outstanding job replacing the broken parts from the toilet. Thanks again for your prompt response and América Home Shield as well.

I had called my home warranty about my water heater not working. That same day action mechanical services called and scheduled an appointment for the next day. Jeremy was supper helpful and friendly! He was able to get my water heater back up and running.

Josh was incredible!!! He had to make two trips, not his fault, and both times he was great! Very friendly! Super knowledgeable! Efficient as all get out and very clean! I would recommend Josh and Action Mechanical Services to everyone I know! Thank you so much!

For the review

The Action Mechanical Services team was fantastic, couldn't be happier with the service. They arrived on time, were incredibly professional, and their workmanship was top-notch. They took the time to explain the installation process and answer all my questions (Replacement Water Heater). Plus, they were so gentle and friendly with our cats, which was a huge plus! I highly recommend them for their excellent work and genuine kindness.

This is the second thing I have had them fix. I highly recommend them. Jeremy did a great job on the first time & this time. He knows his stuff. This time he had a partner to help him, Josh. Definitely will be using them again.

I can't recommend Josh the plumber enough! I was having a major issue with my garbage disposal and a persistent, unpleasant plumbing smell that was affecting my entire home. Josh was an absolute lifesaver. He was incredibly professional, and diagnosed both problems with impressive expertise.

He not only fixed my garbage disposal quickly, but he also managed to completely eliminate the awful smell that other plumbers couldn't solve. His work was top-notch, and the peace of mind that came with it is priceless. If you are looking for a reliable, skilled, and effective plumber, Josh is absolutely the person to call. Five stars all the way!

Josh from Action Mechanical Services came out to our residence on January 09, 2026 to fix a couple faucets for us. Josh was prompt, courteous, and very professional. We have been monitoring the work for a few days and everything seems to be working fine; no leaks or new issues. Great job!

We had a great experience with Action Mechanical Services. Nick came out to check our water heater and was extremely knowledgeable and professional. He took the time to explain everything clearly and made us feel confident about the condition of our system. We were very pleased with the service and would definitely recommend them!

They good for the price

Great service and very helpful

Great bunch of well knowable guys

I was driving down highway 50 and a plumber's supply company truck ran a red light and almost caused an accident. If that's how they drive then I will never let them in my house to fix anything.

Piece of my faucet broke, and no home improvement store carried the part. Showed it to them, and they had it sent to their store from stl within 12 hours.

Very accomdating and helpful in item I was searching for despite not really being open for business. I needed to see a shower unit and they are only open for curbside service. The nice Rep still helped me and I greatly appreciated it.

Vince is amazing! Grateful for his knowledge and amazing customer service.

I walked in today and was not greeted. Two people were standing at the counter and finally I spoke and he looked briefly and said they didn’t have the piece I needed. I guess he would know but I really didn’t feel any effort at all on his part. He almost seemed like he didn’t even want to assist me. I won’t be back!

I went in today to ask about purchasing a couple shower handles. The associate was rude. He asked me what the manufacturer was. I told him i did not know and I think I need universal shower handles. He said they had nothing like that available for me. I can't believe Lowes and Home Depot have a better selection and service than a company that specializes in Plumbing. If that employee worked for me he would be fired instantly for treating a customer that way. I wont refer anyone to this location ever.

Jason is an amazing employee. I had several issues with many trips to the store and phone calls (he even used his personal iPhone to FaceTime me to see the problems that I had). He spent much time with me to ensure that I had the correct parts and giving valuable advise. Thanks so much.

I got a flat tire today & pulled into their parking lot. I went inside, there were 6 male employees & I asked for help putting my spare tire on & one of them replied, “is anyone a mechanic? “, and then proceeded to tell me to call someone else for help. As a nurse, I just can’t imagine not helping someone. I wanted to write this review, not as a customer, but as a reference to the character of the people working here if one day y need customer service, I’d imagine they would have zero motivation to help you.

Was very professional and found the service to be exceptional

Paul is professional, knowledgeable and friendly. He repaired a hot mess a previous 'handyman' made. Changed a leaking main shut off valve, installed new water lines and re-installed a water heater that was arcing (due to a bad install). He works all hours, super early and late night, to get the job done! He'll be our go plumber in STL and IL.
