Each of our blinds and shades are custom made to your specifications and we guarantee they will fit your window perfectly if you follow our measuring instructions. If we make a mistake when manufacturing your blinds or shades we will replace them or fix them at no cost to you. If, however, you make a mistake measuring or entering your measurements into our website we will remake them for you at a discounted price. For this reason we strongly suggest that you follow these instructions carefully and that you double check the measurements you enter.
If you are not confident that you can measure correctly, we recommend that you hire a professional to do it for you. NBI's technicians guarantee their measurements so that, if the technician makes an error, your blinds will be altered or replaced at no charge.
