What Services do Window Installers Offer?

The first step when considering a replacement is to figure out whether you should get a full-frame or pocket installation.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

If you’re still debating which type of installation to get, you can consult with your installer and get their advice. The choice mostly is influenced by how old the frames are and if there’s any damage.
