Our product was conceived as a means to address the time and cost of doing it yourself or paying a carpenter and painter verses the simplicity of adding Luxe Architectural® door moulding kits! Particularly in the case of homeowners wanting to update a house full of plain slab doors, the time / labor savings can be quite substantial as well as the dust, fumes, intrusion, etc involved in replacing doors. Also, in older homes, a lot of doors are not standard sizes due to settling.
