Custom window treatments are an investment in the beauty and style of your home. Pricing varies greatly depending on window size, product type, and control systems.  Motorization, for example, is an option that can add $300-500 or more per window treatment on average. Our clients typically invest between 2-5% of the total value of their home on custom window treatments. Your investment will depend on product selection and whether you do one, several, or all the windows in your home.
