We love working with Sonny from unerstall he has been very knowledgeable and never leaves a mess. We have very pleased with his work.

Came and gave me a quote.explained the project completly. They came and started on time as promised and stayed till complete. Sonny answered all my questions and office staff was very cordial and accomodating. Project was completed as expected with no issues of any kind. I would recommend them highly as an A+ operation all around and would definitely hire them again.
Thank you

Unerstall Foundations was great. They stuck with their bid and charged us only a little for additional work. However, their excavator, T Hill charged double what they said, yes, we asked for additional work, but never imagined it would be over double the original bid. Won't use them again.

The contractors completed the job quickly and efficiently. They presented a better option to re-install the concrete sidewalk. Yet they allowed us to make that final decision of what we thought would look best for the property. In the end we were all happy with the outcome and the completing the job quickly.

The team over here works great together and produces a fantastic product. Albert is great with communication and does what he says he’s going to do. Overall great company!
They’ve done two new apartment complexes for me and 6 more to go!

They did a wonderful job on our sidewalk! They showed up when they promised, did it in one day, and cleaned up after themselves! We could not be happier with the whole experience! Super nice people and first rate work!

Great service from the folks at Unerstall. Owners Albert & Joe were easy to work with and answered my questions promptly and honestly. The work crew was friendly, respectful and professional. My project required additional, unexpected excavation and fill work. The onsite crew, with Justin as foreman, explained each situation that arose, worked with the main office and collectively the correct decisions were made and executed. I couldn't be happier with the customer service and expertise exhibited by Unerstall.

I enjoyed working with unerstall. They were easy to work with and were willing to collaborate with the other contractors who were involved in my construction project.

I reached out twice 6 months ago for a foundation bid. They apologized the second time and still didn’t follow up. I reached out a few more times over the last couple months without a response until they finally told me they are 5 months out now. I wish I hadn’t wasted my time with this company. Terrible communication.

After Unerstall Foundations did the work, our cellar/basement has been dry for the first time in 38 years in our 1880's farm house.

I was very very pleased with the crew from Unerstall Foundations & Flatwork Inc
I am a professional Architect with over 50 years of experience in the building trades. I had a slab and sidewalk poured by Jim's crew. This was not the first time I have poured flatwork, these guy's knew what they were doing. Very good job.

We were going to use this company for our addition until they acted like they didn’t care to do anything and didn’t need the business! VERY VERY RUDE & If you are going to be rude to your customers I’ll use someone else! You were a little cheaper than Mentz but I won’t give my money to disrespectful people! We are using MENTZ & they are AMAZING, fast, and so friendly! I don’t recommend this company at ALL!

This family business is a pleasure to work with. I was dealt with honestly, they met ALL deadlines, offered suggestions for improvements, and the employees are clean and courteous professionals. I can't offer higher praise for them and recommend them to everyone.
Thank you Albert, Cindy, Joe , Tyler, and everyone else.

I had Unerstall pour my shop floor 3 years ago. The price was right and the work was exceptional. I'm standing in my shop right now and floor is as smooth and crack free as the day it was poured!

Unerstall foundations have been doing my work for several years and they are an exceptional company to work with and would be happy to share my thoughts with anyone looking for an exceptional Foundation Contractor.

I had a project with many aspects of concrete work and excavation and this company handled it in a efficient and productive manner. If a had a question they were ease to contact and able to satisfy me in a timely manner. Would recommend them for home expansion projects.
Great job

We are general contractors who have worked with Unerstall from time to time throughout the last 6+ years. They are very knowledgeable contractors with hard working crews. We would and have recommended then to others.

The folks at Unerstall Foundations and Flatwork have been a pleasure to work with. They are true professionals which shows through the work they did for us on our home addition in Webster Groves. Big thanks to Albert and Joe and their incredibly hard working crew!

I have had my construction business for over 40 years and I have rarely worked with a better concrete company.
The owners are wonderful people who have the knowledge and experience to make any project work. The workers are friendly, courteous and hardworking.
I can't say enough good things about this company.

My husband is a new home builder in the west county area and uses Unerstall for all his homes. (Foundations and flatwork) Their relationship spans over many years with many projects successfully completed. Unerstall is outstanding in both communication and quality of work. I recommend Unerstall to both family members as well as for contractors that want a seamless successful process. Thank you everyone at Unerstall Foundations!

I've recommended them to other people because they do great work. They've always been willing to help me out with pouring foundations. I don't have enough time so I know I can count on them!

I have worked with Unerstall Foundations for over 5 years now. Unerstall does all of my foundation work, concrete pouring, and site excavation. The work they do is above and beyond my expectations every time. The workers are very friendly and everything is done right the first time. I have recommended Unerstall Foundations to my of my colleagues and I have never heard a complaint from anyone.
