Although doors manufactured in standard sizes and materials will always be more economical than
custom doors, there are many reasons consumers want customized doors.
First impressions are important so homeowners may want to make
a statement with a one-of-a-kind entry door or unique interior doors. Perhaps they need to fill a non-standard opening, other times they want to match existing decor or woodwork.
Doors can be made of unique materials, clad in copper or aluminum, crafted from exotic woods or someone might want something useful made from interesting wood they own (people have made doors from antique pickle or wine barrels). Open up your imagination!
