I had two drinking fountains installed in less than two days. Superb workmanship. Everything was done on time, and as specified. Work met my expectations and that of the city. Work crew was easy to work with, spoke good english, and took pride in the product

We would be pleased to recommend Prieto Engineering. We found them through a google search, filled out their online form on AllConcrete.com and received our first call from them within seconds. That was enough for us to know they were different. The owner came out to see all of our jobs and sent us a very detailed proposal. When we gave them the job they had workers show up in hard hats and safety glasses, a very clean truck, along with the same owner that visited us in the beginning. They took a few days to do everything. When they left they cleaned everything very well. We are very happy to have found an honest professional.
