After several attempts to get someone to help me remove battery acid rust from my driveway Nick from Sweet Concrete was the only one to come by to look at what I was dealing with. His approach was honest and thorough. He told me up front he couldn’t guarantee all the stain would be removed but he would try his best. With that I told Nick to go ahead. To my complete satisfaction Nick gave me the results I was looking for. I would recommend Sweet Concrete 100%. BTW this the first time I have ever given a review but I felt compelled to do so based on my experience with Nick and Sweet Concrete.
