Custom Window Shop

We have our own production facility allowing us to control the quality of the windows and doors that we order for our clients. We choose not to rely on our window and door distributors because we want to be the best window and door dealer in the region. We pay attention to your wants, needs and job schedule. We don't have to wait for window and door units to be built by a vendor.  Bays, bows, and mulled window units get built and turned around within 1-2 days.

IQ Database

All Andersen® window and door units are quoted and processed through our IQ database. This system links directly with the Andersen® Window and Door factory in Bayport, Minnesota, insuring accurate quotes, drawings, and specifications. We can quote items exactly to your specification and then value-engineer those quotes if necessary.

Tune-Up Service

Hamilton Building Supply is an Andersen® Windows and Doors "Circle of Excellence" dealer. Our two year warranty on labor to replace any part(s) of the Andersen® Windows and Doors our clients purchase from us is an exclusive offer only made by "Circle of Excellence" dealers. We have factory trained Andersen® Window and Door technicians on staff to answer your questions. Our technicians make house calls and are available to perform a survey of your existing windows and doors.
