Age

There are not many types of window seals that come with a lifetime guarantee, and this will especially be the case when it comes to older windows. You are likely to find that the older the method of weather protection, the more likely it is to fail. By updating the weather stripping on your windows as and when it is required, you can ensure that it continues to work effectively.

Elements

Though window seals are designed to withstand whatever the elements can throw at them, there is a limit to what they can take! For example, where certain types of seals are deluged with a large volume of rain on a regular basis, the water can seep behind it and cause it to lift. This can make the failure even worse as the seal will not be flush with the window frame and will allow water and cold air to pass through. Where water comes into contact with metal parts of some types of weather stripping, rust can result which will eventually cause corrosion if it is not rectified as soon as it is noticed.

Mold

If your window regularly suffers condensation which is not wiped away, the window seal can often be affected by mold. This can destroy the effectiveness of the seal, especially when it is made from materials such as rubber. If you notice any mold or discoloration, ensure that you clean it immediately with an alcohol-based cleaner to kill the spores, or with vinegar if you want to use a more natural cleaning substance.

Temperature

The proximity of window seals to the external facade of your home means that it can be subject to extreme ranges of temperature. As well as prolonged exposure to extremes of heat or cold, sudden changes to the temperature can cause some types of window seal to crack, shrink, or sag which will make the weather protection less effective if it does not negate it completely.

Movement

If the window seal has not been fitted correctly or has become dislodged over time, it will not work well as a weatherization method as the weather stripping needs to be fitted in a particular place depending on the variety used and the type of window. All the correct tools and fasteners should be used to fit all weather stripping and replacements must be made when it is necessary.

Maintenance

The instructions that come with most types of weather stripping will often outline what needs to be done in order to maintain it and keep it at its best. Though this will usually mean nothing more than wiping it to keep it dry and clean, it may also outline particular cleaning substances that can be used. Make sure that you undertake the work required to maintain the stripping in line with the material it is made from.
