Now, onto the fun part - preparation! You'll need to measure your door opening to ensure you get the right size, which is easier said than done, trust me. Take your time, grab a tape measure, and don't be afraid to ask for help (or a second opinion, or a third... you get the idea).
Once you've got your measurements, it's time to choose the perfect style - and let me tell you, the Andersen 400 Series has plenty of options to choose from. Do you want a full-view door, a high-view door, or perhaps a low-view door? The choices are endless, and by endless, I mean there are about five options, but still, it's exciting! You'll also need to decide on the frame color and hardware finish, because, let's be real, the details matter.
