A Checklist for Quality Window Replacement

The day your Astoria replacement windows are installed is a very exciting day. You have shopped for the right window, you have selected the best window installer, and you have waited for your new replacement windows to arrive. Do not get too comfortable though, you still need to insure that the installation is done properly so you realize the full potential of your replacement windows. Use the checklist below to make sure your windows are installed cleanly and correctly.

1. Window is installed level - Reading a level is pretty simple. Have the installer place the level on the sill of the window. In the middle of the level is a small clear tube with two lines drawn around it. Inside the tube is a bubble moving back and forth. If the window is level the bubble will sit in between the two lines on the tube.

2. Window is installed square - To determine if a window is square in the opening you will measure the distance from corner to corner across the diagonals of the window frame. The measurements for each diagonal should be the same.

3. Window is installed plumb - When a window is plumb that means that it is installed in the opening straight up and down, not leaning in or out. Checking a window for plumb is similar to checking if it is level. Place the level on the side jamb of the window so that the level is on the interior side of the window frame. The level should be running up and down on the frame of the window. Instead of reading the center bubble, this time you will look for the bubble that will be located at one end of the level. It is designed to work when the level is straight up and down. Just like checking for level, the bubble should sit in between the two lines on the tube.

4. Sealant is evenly applied on the exterior - Sealant around an Astoria replacement window is the barrier that keeps the water out. Verify that there is plenty of sealant applied around all sides of the window. Check to see that there are no holes in the caulk. The sealant should be evenly applied around all sides. Areas with less sealant could dry and crack over time creating a water infiltration problem.
