About Us

Captiva Custom Wood Doors are built at North Atlantic Corp (NAC) in Somerset, MA. NAC is a manufacturer of many fine millwork products including Cooper Stairworks, and a proud distributor of Kolbe Windows and Doors, Masonite, TruStile, WindsorOne, HB&G and many others.

At NAC, we blend high-end, custom woodworking with high-scale, assembly and distribution. Most companies do one or the other, but not both. Our ability to ship a broad range of products allows us to provide unique value to customers – we are the one-stop-shop for all the millwork products on a job.
