What Services do Window Installers Offer?

When considering window replacements, in general there are two kinds that your provider will offer: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has significant deterioration. With this service, your installers will replace the whole window, including the frame, sill and trim. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

Your window installation company should be able to help you figure out which type of installation you should get.
