Signs that window seals are failing are something that should never come as a complete surprise. When a window is first installed, there will be nothing wrong with the window at all, until some time has passed and the signs of wear begin to appear. Sealants will wear out over time and when this happens they will allow air and moisture to get in. The best way to avoid this is to make sure that you have regular maintenance done on your window sealant every two to three years.

One of the signs that window seals are failing is going to be discolouration or fading. If you notice that your windows have faded or that there is starting to be black mould, then you should have them redone as soon as possible. This is because old seals will not hold up well to constant exposure to the sun and this will cause your window sealant to deteriorate over time. It would be in your best interest to have your window re-sealed every couple of years as well.
When looking at these seals, you will see that they are generally made out of a plastic compound. This is the material that goes over the window frame and over the glass before it is installed. Over time it will begin to wear down and start to crumble if it is not taken care of properly. You should keep a close eye on this so that you do not end up with higher energy bills and condensation inside your home because of it.
What damaged seals lead to
When a window seal stops working, whether through wear and tear or poor installation, moisture finds its way in. Over time that damp can damage the frame and the surrounding wall and lead to mould, which can cause health problems when its particles are breathed in.
Ageing seals and gaskets also let air through. Draughts make a room less comfortable, upset the humidity indoors and push up heating bills as you try to keep the warmth in. Condensation is another common sign. It forms when the glass surface is colder than the dew point of the air next to it, and it is worse in cold weather, especially if the air indoors is humid. Condensation on metal frames can point to thermal bridging or windows set poorly in the wall.
Before deciding between repair and replacement, check whether the window is still structurally sound and safe, whether it keeps moisture and draughts out, which components have failed, and whether the problem lies in the adjacent wall. Listed homes may have restrictions on replacement windows.
