We hired Blackstar to finish our driveway, add a sidewalk and replace our deck with a patio. German and his crew, in particular Salvador, were great at communicating and updating us on the project. We are very pleased with the project and the clean-up they did afterwards. We would definitely hire them for future projects.

Very professional. Excellent communications, quality materials, quality craftsmanship and finished on schedule. Completed a major renovation of my backyard, including retaining wall with new pool decking and patio pavers. Definitely amongst the best in the industry.

I hired Blackstar Concrete to lay a back patio and a shed pad. German and his team stayed on schedule, worked diligently, and the end results look fantastic! We were so impressed with how clean they left the area every evening - everything was swept and hosed down, tools were kept in one area, and they laid down boards to prevent mud from tracking everywhere. With no experience in concrete, I appreciated the options that German presented to me and for his expert opinion when asked. He made the process very easy. The end results are incredible and I look forward to using my patio this summer!

I had Blackstar concrete replace a retaining wall in my side yard. German was very professional, organized, and communicated with me during the whole process. At the end of each day when he would leave he always had the area cleaned, which I really appreciated. He finished on time and I couldn't be happier with the results. My family and friends have all complimented the retaining wall. I will definitely be using Blackstar concrete in the future for other projects. I highly recommend Blackstar Concrete.
