They did the job for me past summer.
When I hired them, I must say I was skeptical, because I found them on Homestar, where usually I only hire contractors with reliable references from friends, whether is is a large or small jobs, due bad past experiences. However, none of my friends has concrete driveway, I was forced to take a risk.
I am happy to share that they did a satisfactory job. My driveway has been admired by my neighbors, especially those who have issues with their interlocks.
Without hesitation I would recommend Royal Crown to people who are seeking to have concrete driveway or yards done.
