The midnight blue clapboard siding gave my home a sleek and sophisticated look that stands out beautifully in any light. The color is rich and bold without being overwhelming, and it pairs perfectly with white trim for a clean finish. The horizontal lines of the clapboard add a sense of structure and elegance, and I am beyond happy with how it turned out.

We couldn't be happier with the new siding on our home! We chose the cast iron color and it completely revamped the house, making it warm, elegant and timeless. It strikes the perfect balance between classic and modern, and we've already received several compliments.
We also added shakes to the front gables, and they brought in just the right amount of texture and character. The contrast between the two styles created amazing curb appeal, and our house feels both cozy and high-end.
