Mike at D&I helped me completely change the look of my house! He worked with my decorator to choose the perfect door style and hardware, while ensuring I had the best value options for my project. This saved me time as well as money. Mike is a true professional, taking extra care to ensure my customer experience was “over-the-top!” I am thrilled with D&I and recommend Mike and the D&I team to everyone I know.
