Typical Window Installation Types   Choosing a company to install new windows and doors in your home is a big decision. Hopefully, we can make that decision easier for you. A thorough understanding of what to expect can greatly relieve any anxiety you may have. Also, empowering you with the knowledge of how the work should be performed aids you in evaluating potential companies and eliminating those that cut corners.   There are three basic installation methods. Each has its advantages and limitations. Our window specialists have illustrative diagrams that make these methods easy to understand. We also have multiple photos of completed work that help you envision how your home will look after your new windows are installed. Your consultant will recommend the best method for each of your window openings. New Construction Despite the name, this method is used to replace old windows. This method involves removing the old window and cutting back the siding approximately 1 – 1/2" around the frame. This is done so that the factory flange, which flashes the window and helps to keep it watertight, can be left on the window during the installation process (just like in new construction). The window is then trimmed with clear cedar, sealed and caulked. This is the most preferable method for installing windows in wood siding. Another advantage of this method is that the flange aligns the window on the framing to ensure it is properly supported. Frame Jump This method is used in situations where removing the existing frame could cause damage to the exterior siding. An example would be aluminum windows in marblecrete siding or steel windows in brick. In this method the existing frame is left in place and only the glass and cross members are removed. The new window fits inside the existing frame and is custom sized to an exact fit. A projecting fin trims the exterior and provides protection from the outside elements. This method looks great when properly done but does reduce your daylight opening. It is not a problem on large windows but can be noticeable on small units. This method is used frequently, and for technical reasons, is sometimes mandatory.
