UIP 6, PAGE 1 STAINED-GLASS WINDOWS SECTION UIP 6 GENERAL INFORMATION ILLUSTRATIONS Stained-glass windows are in the fine arts field. Many windows, classified by age or beauty as having antique or historical value, or designed by name artists, must be valued as art objects by fine arts specialists. The majority of stained glass which is installed today is the work of skilled artisans working in shops or studios, who normally put a square foot price on their craft. The following average costs will enable the assessor to estimate the replacement cost or proposed cost within reasonable limits. Glass materials, design and studio prominence vary considerably and costs may vary from a plus 70% to minus 20%. These costs are based on the least dimension of the dominant size of pieces making up the total window. A window, most of whose pieces of glass are 3" wide, would be priced from the 2" to 4" col- umn, whether 3", 6" or 12" long. Price all windows by the area of the enclosing rectangle. INSTALLATION FIGURE 1 Installation costs run from $11.00 to $25.50 per square foot, depending on geographical location, height from ground, and size and shape of window. For stained-glass overlay, costs run $21.75 to $39.50 per square foot including materials.
