Drafts around doors and windows can make your home inefficient, allowing air to move easily in and out of your house. When you have French doors on your patio, you can seal any gap by installing an astragal, which is a wooden strip or molding.
Here are the steps on how to install an astragal on your French door:
- Determine which is the active door, or the door that you usually use when you open or close your French doors. Your astragal will be installed on the inactive door.
- Check which way your active door swings. The astragal’s molding piece should be placed on the side of the French door you are standing on as the door swings away from you.
- Buy the appropriate astragal, keeping in mind the following specifications and measurements: the height of your French doors; the space between the two doors; and the thickness of the doors.
- Clean the surface of your French doors.
- Beginning at the top, press the astragal strip to the side of the door, working your way to the bottom.
- Find the screw holes in the strip and screw the astragal to the door using a drill. If your astragal kit comes with covers, snap them over the screws.
To make the job easier, you can also remove the French door from its frame. Always ask for assistance when removing and replacing a door.
