We had a stamped concrete patio installed by Ryan Diehl in the fall of 2022. The initial quality of the concrete work was very good, and it still looked great a year later. However, by fall of 2024 (2 years), the color had faded significantly. The sealant used appears to have been low quality, and the finish is now discolored and dull. When the patio was installed, Ryan mentioned it should be resealed every 2–5 years and that he could handle the resealing for a fee — all we had to do was reach

Ryan’s crew did a great job on our driveway in Castle Rock. On time and great finish work.

We used Diehl Concrete to replace our driveway a couple weeks ago. The experience was excellent from start to finish. Ryan’s communication, reliability, and work ethic was first class. He was hands on with his experienced crew during the entire two day process. Every detail of the project was done correctly. Thank you, Diehl Concrete!
