What Our Customers Say
⭐⭐⭐⭐⭐Dee - High Ridge, MO
We are absolutely in love with our pool!! After talking to quite a few builders we found Mark and his team knowledgeable and professional. From design to the end we were so pleased. Year two this year and we are still so surprised how little time (and $$!) we need to spend maintaining it. Highly recommend Mark and his team!
⭐⭐⭐⭐⭐Yadi - Fenton, MO
Five stars all the way! The service, the communication, and the overall experience were outstanding. We also use them to close and open our pool every year. Highly recommend!
⭐⭐⭐⭐⭐Cindy - Belleville, IL
I would highly recommend Mark and his team. I was in a unique situation as Mark had to remove my old pool before we started the new one. I am very happy with the results and the service I have gotten since installing my new pool in 2023.
⭐⭐⭐⭐⭐ Gail - St. Charles, MO
Fantastic work
⭐⭐⭐⭐⭐ Cathy - Columbia, IL
Highly recommend STL Pool Days! Met with Mark last Fall to start in Spring. They started 3/12/25 & were completely done by 5/20/25, even with all the Spring rains! Large Gunite pool made to our specifications! Mark & his entire crew were very knowledgeable & kept us informed every step of the way. Excellent communication
⭐⭐⭐⭐⭐Steve - Eureka, MO
If you are considering a pool, I would HIGHLY recommend checking out STL Pool Days. I did my research and got plenty of estimates. The owner, Mark impressed me from day one with his positive attitude, willingness to do whatever we could think up, and his fair pricing. Through the entire project, Mark was a text message away and his response time was almost always immediate. His customer service skills and his team are top notch. We are still amazed every time we look at our backyard and can’t believe we have our own slice of paradise. Skip the headache with other companies and sign with STL Pool days. We would do it all over again in a heartbeat. Thank you!!
