Custom Design Blinds has been dealing with all sorts of blinds installation and measurements for Melbourne homes and offices for over twenty years. We understand that your house plan does have window measurements. However, it has been found that these are not precise measurements that we can use for making blinds. Therefore, we take our own measurements whenever you hire us for blinds installation. We don’t rely on the house plan for these measurements and use highly precise tools to measure the windows. Moreover, if you want us to make blinds for two similar windows then also we prefer to take measurements of both the windows separately. This helps in making just the perfect blind and thereby delivering customer satisfaction.
