Did my back patio and built a grilling station. Well few months later I had cracks in the concrete and chipping. The built in grilling station was a waste, when I changed grills my new grill wouldn’t fit I called Ken to see if could widening the space so that my new grill would fit. Well now that he had my money he lied and continue to say he would show up and never did. I would not do business with him! My warning to you!
