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.
