Before the first survey.
Can I use my own dimensions?
Yes. This demo lets you change width and height. For a real order, your measurements are a starting point; a survey determines the final dimensions.
Why might the final price change?
Profile, glazing, hardware, opening style, preparation and installation affect the total. This illustrative estimate demonstrates the experience, not a real price list.
Is this a real glazing business?
