5 Steps To Repair Jalousie Windows

If your window has horizontal glass that is hung between a wooden frame then you have a louvered window, also known as Jalousie window. They are known to bring fresh air into the room without bringing the sun or rain into your house. However, like anything else it needs to be repaired every now and again, which is why you need to check several problematic areas constantly so you can sustain your window.

5 Steps To Repair Jalousie Windows

Louvered windows were popular in the 40s, but it grew out of fashion in later years. This means that the jalousies found in smoking rooms, sunrooms, gazebos, and enclosed porches have been around for some time now and need to be tweaked or fixed.

Step One

The first thing you need to do is check the crack handle, if it is broken, then you need to replace it right away. Unfortunately, you can’t repair the handle itself. This means that you will need to buy a new one, which shouldn’t be a problem since they are inexpensive anyway. You can easily get one from the hardware store near you.

Step Two

Now you need to check on the arm mechanism. If you can’t open or close your window smoothly, then the metal is probably bent. First, you need to unscrew the screw. Then you need to unscrew the bent metal from its place and then screw a new one instead of it. After securing it into its place, open and close the window gently, so you can make sure that it works.

Step Three

If you have had jalousie windows for a while now, then you might want to check on the rivet head. When these windows have been used for years, the first thing that tends to break is the rivet head. This means that you need to drill out the old rivet. Try as much as possible not to create a hole as you are doing so, so that you don’t face any problems when you are putting the new one in.

Step Four

After fixing all these areas, it’s time to fix the window stops. It is easy to know whether they need to be repaired or not. If your window looks like it is coming out of its place, chances are the stops need to be fixed. All you need to do is to push the window from the outside, as someone else cranks it from the inside. Once you’ve done that detach the screen and raise the window until you can see the stop. Put the stop back in its place, then return everything back again.

Step Five

The final thing that will need fixing is the metals in the window. You have probably noticed that they have become rusty, sticky and dirty over time. This means that you will need to use oil or some kind of lubricant to fix your metals. Simply spray the lubricant on the dirty spot, so you can easily open and close the window.

Jalousie windows are fairly easy to repair; they don’t take much of your time and they require low maintenance. They only need to be repaired once a year, so you don’t need to frequently check if it’s working or not. Besides, if you follow these steps, you probably won’t need to repair it for a long time. Just remember to check on the crack handle, arm mechanism, rivet head, stops, and rusty metal.
