With dedication and experience, there is full understanding of the lasting impression an entry, interior or exterior door has on a home or business. Wood products are purchased thoughtfully and used completely, as environmental responsibility and the support of sustainable forests is prioritized. 


More Than Just A Door


Castlewood Doors and Millwork manufactures and designs interior, exterior, and specialty doors. Available in all shapes, sizes, wood species, and configurations. We often have requests to combine several materials like metal and glass or metal and wood. Each design is an original masterpiece. Your satisfaction is guaranteed.





Castlewood Doors are built using engineered construction. Door stiles have a warp resistant timberstrand core along with a resawn solid wood veneer ranging from 1/8” to 1/4“ thick. Interior door panels are solid wood. Exterior panels are separated by a plywood core to allow freedom of movement to accommodate the different climates of the interior vs the exterior of your home. All doors are constructed using 1/2” x 4” dowels in addition to the mortise and tenon jointery. Constructed using Formaldehyde-free glue.
