Josh took his time and attention with cleaning my sidewalk and driveway. He went above and beyond to clean a small slab outside of our garage side door and the concrete our condenser unit sits on. He didn't just clean it, he applied other material to keep it cleaner for longer. When my family went to see the finished product, we were astonished by the change. It made our house brighter, if that makes any sense. It looks so good. I don't even want to drive on it. Thanks Kraken Kleen!
