Replacement Window Installation
Window and door installations vary greatly depending upon the age and style of the home as well as the products being installed. There are many ways of taking out an old window or door and installing a new one, but there are only a few ways that will hold up over time. It is critically important that the exterior integrity of the home is maintained throughout the installation process. The best products will perform poorly and fail over time without proper installation.
Generally speaking, if the old window has a nail fin then the new window should have one too. Installing the new window with the fin is just the beginning. The new window must be properly integrated into the wall structure utilizing multiple sealing layers. A weatherboard system of layering is used during the installation process, which ensures that the harsh winter rains will not be able to penetrate into the walls.
