If you need a window replacement, you are likely to call a company that sells windows or a window and door contractor that installs windows. As you examine your broken window and look for a way to keep bugs and other critters out until the window is replaced, you might begin to wonder about what holds a window in place in the first place. After all, these are heavy structures that do not simply pop in and out and just stay put during high winds and storms. As your window installation expert begins work, you will see him/her do the following.
Running a Blade Along the Edges
The old window is currently held in place with whatever bonding agent the prior installation expert used to place the window. Your current expert will run a blade along the edges of your damaged window to loosen this bond. Firring strips (i.e., strips of wood used to buffer the edges of a door or window) may need to be removed with a prying bar. Now the old window is ready to come out.
A Nudge, a Push, a Pull, a Tap
Depending on how tightly the window is pushed into the frame, the installation expert will need to nudge, push, pull or lightly tap the edges until the window begins to fall. At this point, two installation experts need to be present and ready to catch the old window and remove it. They set the old window aside and/or place it on the truck to remove it from your property altogether.
A Quick Cleaning and Application of Adhesive
Next, the installation experts clean up the areas where the old window sat. Removing paint flakes and smoothing edges is important for a seamless fit for the new window. Whatever adhesive or bonding agent they use is applied to the frame and then the new window is popped into place. A caulking agent may be used as the final step to seal the edges around the window, keep it from falling out, and prevent bugs and drafts from getting into your home.
Replacing Firring Strips
If need be, your installation experts will now replace the firring strips. These buffer up against the sides, top and/or bottom edges of your new window and act as an extra preventive measure against the window falling forward. Not all windows need them, but they are often used on older houses where the window frames are not quite perfect.
