When the weather gets colder, many homeowners notice a draught coming from their uPVC windows. The window is closed, the handle is turned all the way, but there is still a cold feeling near the frame or windowsill.
The first thought is often that the windows need replacing. In reality, the problem is sometimes much simpler to fix.
Check the window seals first
The rubber seals around a window wear out over time. This is especially common with older windows that haven't been maintained regularly. The rubber can become hard, lose its flexibility or crack, making it harder for the seal to keep cold air out.
In this case, replacing the seals may solve the problem. However, it's important to choose the correct type of seal, as not every profile is suitable for every window.
Sometimes, the window simply needs adjusting
Another common reason for draughts is that the window sash isn't closing tightly enough against the frame. This can happen if the sash has dropped slightly or the window hardware isn't working as it should.
A proper inspection can help determine whether the window needs adjusting or whether some of the hardware has worn out.
It's best not to turn every adjustment screw yourself without knowing what it does. Incorrect adjustments can make the problem worse.
What if the draught is coming from around the frame?
In this case, the cause may be completely different.
If cold air is coming from between the window frame and the wall rather than between the sash and the frame, the installation joint may be damaged or poorly sealed.
Replacing the rubber seals or adjusting the window won't solve this problem. The connection between the frame and the wall needs to be checked.
That's why it's important to identify where the cold air is coming from before deciding what repair is needed.
How can you tell what's wrong with your window?
There are a few things worth paying attention to:
-
Cold air around the opening sash: the seals and closing pressure may need checking.
-
A draught coming from one corner: the sash may not be closing evenly against the frame.
-
Cold air coming from between the frame and the wall: the installation joint may need attention.
-
The handle is difficult to turn or the window doesn't close properly: the hardware or window adjustment may be the cause.
These are useful starting points, but they don't provide a definite diagnosis. Sometimes more than one issue needs to be addressed.
Do you really need to replace the whole window?
Not necessarily. In many cases, existing uPVC windows can be brought back into good working condition by adjusting the sash, replacing worn seals or repairing the hardware.
The important thing is to identify the actual cause before spending money on repairs or replacement.
