Call Bill Hepburn the originator of the Magnum Historic, High-Performance, Replica Window System.

"Bill Hepburn built replica windows to replace our 100 plus year old windows using Indiana poplar, high tech cladding, and double pane insulated glass exactly duplicating the ornate Victorian window design. We have received many compliments on our new windows, which fit our house so well. Bill is a true craftsman." - G.M., Chrisman IL

"The originals are round-top double-hung with arched muntins...our preservation commission (and) Historic Landmarks Foundation strongly recommended that I have windows fabricated to look like the originals...I could not be more pleased with the craftmanship and professionalism...I would highly recommend Bill Hepburn and Heirloom Windows" - M.P.S.
