The answer is in your favor. Casement windows are usually not supposed to leak in standard condition. Still, there are other factors you have to consider.

If your casement window is tightly locked into its frame, as it should be, then there is no risk of leaking. There is very little space in casement windows, which are kept for air seeps. But these won’t disturb you as they are way smaller for water to leak. 

So, If your window is a casement one and it is still leaking, it could mean that there is some damage or any other problem that you have to fix.

Reasons Your Casement Windows Might Leak

One of the prevalent issues with windows is leakage. While a casement window in the standard condition is supposed to protect you from any leaking, there are still sufficient reasons that might cause it to leak.

If you notice any form of leaking from the window or the window frame, it was most likely caused by your window.

Lots of reasons might be liable for leakage in casement windows. Damaged caulking, a loose gasket, or faulty fitting are the most common among them.

The probability that problems may arise also depends on the kind of casement windows you are using. Let’s check out some most known types and how likely they are to cause problems like these.

The Most Common Issues of Casement Windows

Windows are the shield protecting you from the sun, the rain, the snow, the wind, and most other natural calamities you can call out. So it’s obvious to face problems regarding windows.

Many issues can arise relating to the windows in your house. Even the best windows out there can manifest complications. Thus, you should be aware of the most frequent window problems and how to resolve them correctly.

1. Jammed Windows

It is typical to have difficulty opening or closing a window, but the answer is far too simple.

How Does It Happen

The type of window you have is relatable in this case. It determines whether you face a problem with jammed windows or windows that are hard to open or close.

If your window or frame is made of wood, the swelling of the wood, as well as dirt or debris on the window, could be the source of the problem.

On the contrary, if the window is a casement or awning, it is a problem with the hardware used in the installation.  

How to fix it?

The key to solving most problems like these are routine maintenance. Clean your window on a regular basis. This will keep the window working smoothly and help you easily open and close it.

Using lubricant on the window frame’s track is also another option. Take good care of the spring mechanism. This will also aid in the smoother closing and opening of the window.

In case it is a casement window, look after the moving parts of the window and wherever necessary, to make it smooth, apply a lubricant.

If these solutions can’t help you, you might consider replacing them. You can get it at a low cost.

2. Drafty Windows

It is the most prevalent issue encountered by all window users. This problem is mainly noticeable in the winter. It prevents the heater from warming the house, and you can not sit beside the window because of the cold.

It also raises the expense of your heating system, putting you in a difficult financial situation.

How Does It Happen

Many things could cause this problem. If you newly installed a window, a fault in the installation might be a reason behind it. If this is not the case, it may occur as a result of-

  • Old weatherstripping
  • Damage from extreme weather
  • Seasonal weather fluctuations distort the frame.

How to fix it?

The answer might vary depending on the reason. If the problem is with the weatherstripping, it can be readily repaired by changing it. Nevertheless, if the damage is severe, such as from unusual weather or wrapping the frame, I recommend that you change the window as soon as possible.

3. Condensation Along The Bottom Of The Window

In most cases, the window itself cannot be the cause of such issues.

How Does It Happen

It occurs because of the access level of humidity in a house. The moisture can be caused by cooking, showering, and breathing also.

When the air in your room warms up, it collides with the cold window glass and forms it. Water in the window rolls down to the bottom of the glass due to this.

Since new windows are way more airtight than older ones, this problem occurs more frequently with those.

How to fix it?

This problem is a straightforward one to solve. You have to keep your window open for a small amount of time. It’s because of this aids in the removal of dry air from the room and the entrance of humid air. When you’re taking a shower, turn on the bathroom exhaust fan as well.

4. Condensation Between The Window Panes

This problem only happens when you have double or triple-pane windows. It is not applicable for single panes. 

How Does It Happen

Sandwiching is the method of double or triple pane windows work. The gas is trapped between two or three layers of glass that are sealed together.

The seal is excellent, but if wet air becomes trapped, it might cause damage. You need to release the gas.

How to fix it?

At this point, I have to disappoint you because there is no specific solution to this problem. 

You can unseal the panes to release the gas and then seal it again, but if you do it repeatedly, then the window can not give you a long time of service. At this point, the only answer is a replacement. 

5. Leaky Windows

Leaky windows are one of the most annoying problems one might face regarding windows. It not only damages the window and the frame but also causes molds to grow because of the moisture released. Moreover, it is pretty painful to clean up the water again and again.

There are various ways to solve this problem. The easiest one is to find out the reason for the leakage first. After that, double-check to see if the windows are firmly closed. You should also inspect the locking mechanisms to ensure that they are in proper working condition. This will at least help you prevent damages caused by rain.

How Does It Happen

Two sources can cause problems such as leaky windows-

  • The window itself
  • A leak from another source

Most of the time, the window itself is the source of the problem. So check and see if there is any leak in the window frame. If you find any, the reason could be most probably damaged caulking, loose gaskets or improper installation. 

The wall around the window, on the other hand, could cause the same problem. If the wall around it is leaking, it may damage the window and make it leak as well.  

How to fix it?

The answer to the question, if it can be fixed, depends on two vital points-

  • The source of the leak 
  • How bad it is

In case the leak originates from the wall or the roof, don’t try to fix it yourself. The best method is to contact a professional who is an expert, especially in this sector and close the leakage. 

Otherwise, the water from the leakage can help grow molds and damp the wall, which is detrimental to both your house and your health.

If, on the other hand, the leakage is coming from the window, you might be able to repair it yourself. Use the suitable method for specific causes. For instance, if the problem is old caulking, remove it, clean the area well and install a new one. 

If you are confused about the source of the problem, and the solutions mentioned above can’t help you, then it is high time you called a professional or replaced the window.

Types Of Casement Windows

In general, window companies provide three kinds of casement windows. They are-

  1. Single Frame casement windows
  2. French Casement Windows
  3. Push-Out Casement Windows

This classification is based on several things, including structure, features, and design. It is influenced by your personal preferences, financial constraints, and the architecture of your home too.

However, installing a french casement window is more expensive than installing a single casement window.

Advantages:
