I've been to James Allen Concrete at their Polk City City location and had a solid experience. The business is easily accessible, located at Building 14871, Brahma Rd Road. You can reach them during their working hours, which include every day of the week from 8 in the morning to 5 in the evening. Their phone number is +18636486128, and they also have a partnership with James Allen Concrete. However, I had some concerns about their commitment to novel methods or techniques in their concrete work. Their overall impression was positive, however, the quality of work was not at its best, but the prices they charge are relatively reasonable. They are open every day, so that's convenient. The concrete work was done in a professional manner. Their business hours are consistent every week.
