A question I am often asked is “I would like a stained glass window making how much will it cost me?” This is a difficult to question to answer because without understanding what the client wants it is difficult to provide an accurate costing. However a budget for a typical original stained glass panel would be a design charge of £100 to £150 and a manufacturing cost in the range of £75 to £130 per square foot. The costing depends on a number of factors but it comes down to the cost of the materials, the cost of labour and the shipping and installation costs.
For a typical panel the main variable in the material cost is the cost of the price of the glass. The cost of stained glass can range from £20 per square metre for machine made glass to over £150 per square metre for hand blown glass. The panel’s design affects the number of pieces that can be cut out from a sheet of glass. For example leaves will be cut to follow the flow in the glass reducing the number of pieces that can be cut from a sheet. Irregular shapes will also result in higher amount of wastage. The material cost is therefore a combination of the cost of the glass and the expected yield per sheet.
The labour costs are driven by the number of pieces and the complexity of the design. A leaded window with rectangular panels is a lot faster to make than one with complex cuts. The more pieces a panel has and the more complex the designs then the longer it will take to cut, build, lead and cement.
