Exterior Shutter and Custom Door Construction


Estate Millwork hand-crafted Exterior Shutters are created by a team of skilled wood workers who ply their craft in a state of the art manufacturing facility in the timber-rich foothills of the Allegheny mountains of Western Pennsylvania to meet the demanding specifications of our customers for custom hardwood doors.


Although the mill of our family owned business was originally built during the 1930s, we have some of the most sophisticated wood working machinery and software available today, much of which was designed and built by Estate Millwork for its exclusive use.

Our Construction Process

Every Estate Millwork door begins with hand-selected FAS-grade lumber that is kiln-dried to optimal moisture content in our climate-controlled facility. Stiles and rails are milled from rough stock on-site, ensuring fresh surfaces for strong glue bonds. Rails are double-tenoned and pegged with matching hardwood dowels into deep pocket blind mortises, creating joints that resist racking and seasonal wood movement. Louvers are deep-seated into precision-routed slots, and panel frames float within the frame to accommodate natural expansion and contraction without cracking or binding.

This traditional joinery approach, combined with modern CNC precision, produces doors that meet the exacting standards of architects, preservation societies, and discerning homeowners. Whether you need a single custom door or a full set for a historic restoration, our construction methods remain the same. Contact us at 412-641-0177 to discuss your project specifications.
