Sometimes, all you need is a screwdriver to help adjust your double glazed windows and make them functional and efficient again. Read on to learn more about adjusting your windows.

How do you know if you need to adjust your windows?

This is a common question we hear from customers. How can you tell if you have a faulty window or just one that needs to be properly adjusted. Here are some of the common signs that your windows have “dropped” in the frame and simply need to be adjusted in order to make them efficient again. 

Bear in mind that many of these problems can also indicate issues with your windows that will require more extensive repairs. So if you adjust your windows and it doesn’t fix the issues, this could be a sign that you need to replace either the glazing, the frame or both. Here are some of the most common issues when your windows need to be adjusted:

Window won’t close properly

If you struggle to open or close your window and the mechanism doesn’t run as smoothly as it used to, this could be a sign that your windows need to be adjusted. When the window frames shift, this can make it difficult for you to open and close the windows. If left without adjustment, this can cause damage to the frames and handles over time.

Windows are draughty

If you notice a draught around your windows, this could indicate that you need to adjust them. When your windows have dropped in the frame, this impacts the window gaskets which help to prevent airflow. Try closing the vents at the top of your frame and then check again to see if they are still draughty.

There is a gap in the seal

If you can see a visible gap in the seal, this is a good indicator that you need to adjust your windows. Gaps in the seal will make it difficult to keep your home warm in the winter and will also impact the sound proofing side of your windows. If you notice noises from outside are bothering you more than usual, you might have a gap in your seals.

The first thing you need to do is open your windows. This can be difficult if the frames have dropped, but try to do this without too much force, as it could damage the frames or even smash the glass and lead to an injury.

Next, locate the metal mechanism that allows the window to open and close. This will typically be an arm that extends between the window and the frame. Follow this to the edges where you should find an adjustable screw. There may be 2-4 screws on each window. You will need to loosen each one by a full turn to make it possible to move the window.

If you are struggling to close the window, you’ll need to move it downwards. And if the window has been sticking to the frame, you’ll need to move it upwards.

Once you have found the right height for your windows, you can tighten the screw. In a window that opens like a door, you will need to move it left or right rather than up or down.

What if this doesn’t fix the problem?

If you are still struggling to open and close your windows or if you notice a draught, it could be another issue entirely. Adjusting the frames is often the easiest first step in troubleshooting the issue. If the problem persists, it could be a fault with the frame mechanism, or it could be an issue with the window seal. Call in a professional to diagnose the problem and determine if you need new windows, new glazing, or if there is a simple fix.
