Coy Construction is a Michigan Building Company that enjoys a rich and proud 20 year tradition within the remodeling industry. From our company’s inception in 1979, our focus has been to specialize in building wood decks and basement remodeling. Rather than expanding into other types of construction products, we chose to grow our business by simply building more decks & remodeling more basements. Qualified Remodeling magazine ranks us as the largest producer of these 2 products nationally! We found our “niche” and we’re sticking with it.
