Hamilton Building Supply stocks more interior doors than any other distributor in the area. Our state-of-the-art Interior Door Shop enables us to produce such specialty products as trapezoid-shaped cut-down units and full access bi-fold doors. Our sales associates will provide you with personalized service as they guide you through the door selection process. Almost all interior door units are assembled and pre-hung on site in our Residential Door Shop under strict quality control procedures. We even machine new doors for existing frames so that updating the doors in an older home couldn’t be easier. Simply bring your existing door to us and we will match your new door perfectly so that all you need do is put the door back on the existing hinges.
