DoubleGlazingApp is the latest and easiest way to price your new double glazing units. You can measure and price at your own pace and if you need help from the professionals you can use the inbuilt assistance button. The app includes an assistive measuring device which helps with the measuring when you don’t have a tape measure to hand. Once you have measured the units you require, you can submit these directly to the installer who will help you with the next stage of your enquiry.
