What Services do Window Installers Offer?

In regard to window installations, in general there are two types that your provider will have: full-frame and pocket installations.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are on the simpler end and won’t carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

If you’re unsure which type of window installation service you need, your installer can help you out. Generally, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.
