5.0 Stacy K. Town And Country, MO

I would highly recommend Stratum Structural. Extremely knowledgeable, reasonably priced and excellent and pleasant customer service all around. Initial visit - did not over sell and did a great job explaining requirements/process. During work - great job explaining the process and cleaning up.

Response from Company:

Thank you Stacy. We appreciate your trust in allowing Stratum to install your egress window!

5.0 Barb W. Warrenton, MO

Stratum is a top notch company, from the owners to the workers. They are honest, reasonably priced, courteous, clean and and extremely knowledgeable. They just completed a very complex foundation repair, and we could not be more pleased. As a Realtor, I also recommend them to my clients, and everyone who has used them has loved them. Thanks for the great job, Stratum!!

Response from Company:

Thank you Barb. We appreciate your trust and your kind words about our employees.

4.0 Jared E. Watervliet, NY

Overall pleased with the end result but I was told someone would return to take care of a minor issue that remained from the installation (exterior trim piece), but no one returned. I contacted Stratum later, but I did not receive a response.

Response from Company:

Thank you for your kind words and the time it took to give your feedback. We have now replaced the trim so you should be all taken care of. Please let us know if we can do anything in the future for you.

5.0 Justin B. Saint Louis, MO

Outstanding customer service and didn’t push me into spending more than I needed. Gave me a great deal on my basement repair. Gave me a great repair solution and it seems to be holding back all the water. With the ton of rain, my basement is dry. Would call them again for other repairs I need.

Response from Company:

Thank you Justin We appreciate the opportunity to work with you.

5.0 Karen M. Grover, MO

After 30 years in our home, we began finding several cracks in our 2-story vaulted great room and our foyers. We thought it was just some minor settling but it ended up being major foundation settling that needed to be addressed. Tim came out and inspected everything and provided a quote. He was wonderful to work with and because we had a very large project, he went out of his way to try to find some ways to lower the cost. Ultimately, it was not our most inexpensive quote but we felt most comfortable with Stratum and their reputation. We cannot say enough positive things about the young men who then came to work on our foundation. They were kind, considerate, polite, and always took time to answer all our questions as our piers were installed. They encountered more water than one would expect around our foundation and ultimately ended up recommending a new waterproofing system and a second sump pump while a lot of the foundation was already opened up. This saved a lot in pricing because it was done right after the piers and before the concrete was replaced. While one never enjoys spending a lot of money on a foundation, we are glad we found and used Stratum for our needs. We totally recommend them to anyone needing foundation/waterproofing needs.

Response from Company:

Thank you Karen! We appreciate your kind words and your trust in Stratum!

5.0 Richard E. Saint Louis, MO

Jacob, the Stratum Structural Systems Technician, was knowledgeable of how top repair the foundation crack. He was efficient in his work and cleaned up after the work was completely. He instructed me what to do after the crack was repaired. After it had rained, there were no leaks, so the crack was repaired correctly.

Response from Company:

Thank you, Richard. We appreciate the time you took to share your Stratum experience.

5.0 David G. Saint Peters, MO

Great company, excellent customer service. Keven, Mike & Brad all top notch employees. Will recommend to any and everyone. Thank-you!

Response from Company:

Thank you David. We are happy to have helped install your egress window and we appreciate you taking the time to share your Stratum experience.

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
