Insert sample windows demonstrated during in-home presentations may create confusion because of their configuration. For convenience, insert window samples are often housed in a carrying case making them look like a full frame window. A full frame replacement window includes removing the entire window frame and sash, along with the interior and exterior trim. An insert replacement window includes removing and replacing the sash. The original frame is not replaced. It is important to see a sample of the actual window that will go into your home before signing a contract. Seeing a sample of the window being purchased will avoid confusion about what is or is not being replaced. Also, double check your contract to make sure that the type of window (Full Frame or Insert) is clearly stated.
