Proudly serving O'Fallon, IL

Excellent company to work with. They do incredible work and they handle themselves professionally while still feeling very personal.

We had a custom-stamped concrete patio design. Tim worked with us and Immaculate Concrete did a fantastic job.

Immaculate Concrete and Construction did an amazing job on my driveway and in my crawlspace! They were punctual, professional, and communicated well throughout both projects. I’ll be using them for future projects.

Tim is the real deal! He is a man of his word and his crew was great! They came in, did exactly what they said they would do and it turned out amazing. If you need any work done Tim is your guy! and people who know me I just dont throw around compliments.

Watched Timothy and his crew set up and pour a patio at our home. The quality of work and professionalisms was the best I have ever witnessed. I would highly recommend you choose them to do any concrete work.

A huge thanks to Tim and his crew for a fantastic job on creating a new patio to replace an old and small slab. I appreciate his input and ideas since I really didn't have a solid plan on exactly what I wanted. Watching it transform from old to something with that wow factor was enjoyable to watch. Very easy to deal with and a professional crew made the whole project extremely worth it. Pure quality! Thanks again and looking forward to its many uses!!

We had a patio and sidewalk poured by Immaculate Concrete and it turned out great! We are very happy with the results and will use Immaculate Concrete again in the future. Highly recommend if you are needing any work done.

Fantastic! Tim was a huge piece of transforming my backyard, which I’m now looking forward to spending more time in. Going in, I knew I wanted a basic concrete patio poured and he provided great suggestions on the design, even accommodating a last minute request to add in a sidewalk and adjusting plans for the layout and placement. He was great about communicating when the project would start and end and on providing updates while I was out of town. The crew worked fast and did a great job, I have zero complaints. The details really mattered, and they even helped with seeding grass and placing new landscaping rock to help tie things together at the end. Thanks again!

This crew did an amazing job for us and our walk way for the side of our home. I also run a local Plumbing, Heating & Air Conditioning business that they were able to help out with a project on as well. If it isn’t from small projects to full blown street/curb repair, this crew has it on lock. They not only did a great job, but also left flowers on the finished product a week later. Thank you, Immaculate Concrete for the great communication and quality work. We will be happy to use you for any future personal or business needs!

Immaculate Concrete and Construction did an amazing job on our driveway! They were professional, punctual, and communicated incredibly well throughout the entire process. This is the second project they’ve completed for me, and I’ll absolutely be using them again for future projects.

I just had my patio enlarged by Tim Nast. He did a fantastic job. I was very pleased with the finished product. Tim went the extra mile and brought in dirt to put around the patio due to the incline of my yard, then seeded it and put straw down. Tim is very personable and great to work with.

I just have to take a moment to give a HUGE shoutout to my nephew Timothy and his company, Immaculate Concrete! 🙌 They completely transformed my home with a brand new driveway, front porch, and sidewalks for both the house and garage—and I couldn’t be happier with how everything turned out. The craftsmanship, attention to detail, and pride they put into their work truly show in every inch. The name “Immaculate Concrete” couldn’t be more fitting—it’s a true reflection of the quality and professionalism they deliver. Everything looks absolutely amazing! If you’re looking for someone reliable, hardworking, and who takes real pride in what they do, I highly recommend them. Thank you again, Timothy—you did an incredible job!

I could not be more satisfied with the work done by Tim at Immaculate Concrete. I had a difficult situation my concrete patio sank and water was running toward the house making it worse. I had another vendor try to polyjack but it just turned the patio into a big puddle. I also had my 25 year old post bases corroding and needing replaced and other bids didn’t want to touch them. Tim went above and beyond to solve my issues. My only regret is throwing away money at the polyjacking before I reached out to Immaculate Concrete. It is also good to support a veteran owned business.

I recently added a 10x30 patio extension and Tim did the work. He was early each day, did what he said he would, and was easy to work with (super nice guy). The patio itself looks amazing and is already in heavy use. Very happy and would reach out to Tim again for other jobs.

Had a great experience with Tim Nast! Came out on a Friday afternoon to access what I wanted done and was back bright n early Monday morning to get the job done! He did a great job at replacing my sidewalk in front of my house! Love that I can walk fully out to the street now without having to step into the grass especially on the crappy weather days!

Tim did an outstanding job on our driveway add-on and concrete pad for our portable building. I highly recommend him!!

I had a pretty good idea of what I wanted to hear from a concrete contractor and from the moment Tim showed up he knew exactly what went wrong and how he was going to fix it. He emphasized how he would make sure it actually lasts. Tim was super easy to work with and great communication the whole time. It’s hard to find good, reliable help at a fair price, but they really went above and beyond. Couldn’t be happier with how it worked out.

Tim and Jimmy with Immaculate Concrete and Construction did an amazing job on our crawl space. Tim made the whole process very easy from start to finish. You can tell he has very high standards and takes great pride in his work. I always try and pick local and veteran owned companies and with Immaculate Concrete and Construction you get both. I will definitely use this company again and highly recommend them if you’re looking for a friendly reliable company that does amazing work.
