4 Reasons Why Your Windows Are Leaking

Leaking windows are usually caused due to poor installation or because the windows are old and the key parts such as the seals have degraded over time.

If you have a leaky window, then don’t just ignore it, as it will only get worse if you do not fix the issue on time. If you notice water around your windows, immediately call a certified window company and get your windows replaced or repaired by a professional.

If you keep ignoring this issue, it will cause significant damage to your windows, and your home’s interior will be affected by mildew, rot, and mould problems. In the end, your house’s integrity will be compromised altogether.

There are many causes of leaking windows. Thus, finding out the reason behind your leaking window is the first step that will help you detect and rectify the problem.

Keep on reading, to learn the top 4 common causes of leaking windows.

Common Causes Of Leaking Windows

An important thing that you should know is that sometimes condensation on the interior of your windows can be mistaken for leaking.

Mostly, condensation is caused due to excessive moisture in the house. For instance, when the air inside is warmer than the air outside. If condensation happens between your windows panes, then the seal of your window may be broken.

So before replacing your windows, make sure that you do not have an issue with condensation.

Here are 4 common causes of why your windows may leak:

Poor Installation

The most common cause of leaking windows is improper installation. Most windows leak because they are not installed properly.

A window might look perfectly installed to the untrained eye, but only a professional will be able to tell if there are gaps between the frame and window or if the seal is not installed correctly.

In some cases, unprofessional window installers use building paper or house wrap rather than proper window flashing while installing windows. This results in water seeping into the wall of your house.

Broken Sealing

Windows are usually sealed with expanding foam that prevents them from leaking. But if the sealing is not appropriately installed, the gaps will create channels of air between the windows and wall that will lead to leakage.

To ensure your window sealing is installed properly, you should hire certified window installers as they will accurately measure the aperture and install your windows to fit the frame properly. Getting windows that are too small and filling in the gaps with foam is not a good practice as it increases the chances of window leakage.

Bad Glass Seal

If water is leaking through the window but stays between the glass panes, then it is because you have a bad glass seal. This also means that the water will make its way into your home, and the house will lose its insulating gas that helps keep the cold inside and the heat outside in summer and vice-versa in winter.

Hence, this bad glass seal will make your windows less energy-efficient and eventually increase your heating and cooling costs.

With a paint seal around the glass, you can increase the level of protection of your window glass seal. For this, you just simply overlap the paint very slightly on the glass seal, which is not even visually noticeable but creates a protective layer that seals the windows glass against moisture.

Missing Overhangs

If your house does not have overhangs that drain water off the roof, then your windows will receive higher than the average amount of rainfall water. Resultantly, this will lead to window leaking. Also, the fascia boards above your windows should be placed at an angle that makes sure that the water is directed away from the windows.
