Steamed Up Windows (Why It Happens & Is It Normal?)

Steamed-up windows are a normal and common occurrence, especially if your window is double glazed. However, it’s not a good sign if the steam is within your window. Windows are sealed, and when your windows steam up it could be due to improper installation, or likely because over time the sealant can break down, causing air to enter. 

This article will talk about if it’s normal to have a steamed-up window, why it happens, preventative measures to stop it from happening, and frequently asked questions in regards to this topic. 

Steamed up windows- is it normal?

Steamed up windows- is it normal? Yes, it’s normal and common to have steamed-up windows, but it’s not always a good thing. If you have steam in the sense of condensation, that’s nothing to worry about. But if the steam is within your windows, it’s not something that should happen. 

Why do your windows steam up?

The cause of steamed-up windows in terms of condensation is due to inadequate room heating, poor thermal insulation, or insufficient ventilation, and excess moisture in the air. The other reason why you have steamed-up windows is because of airflow inside your windows, due to the barrier of the sealant of your windows being broken. 

How do your windows steam up?

Chemicals over time are a common reason why your window seal breaks down. Other times, there can be manufacturer problems or even improper installation which can also cause airflow and issues with your window’s seal. Usually, the ladder is noticeable because it will occur on newly bought and installed windows. If your window is wet to the touch, then there is a build-up of condensation, which is usually from temperature fluctuations. 

How can you tell the difference between steamed-up windows and condensation?

Condensation will make your window wet to the touch indoors, outdoors, or both. Stemmed-up window glass is actually between the pains of glass, so it will be dry to the touch. Hence why it’s more common with double-paned window glass. 

Can steamed-up windows be bad?

Although visually unappealing, steamed-up windows won’t kill you. They are a sign of your window not having very good insulation. This is bad in terms of moisture and heat loss, as well as the overall energy efficiency of your house. If the steam is inside your window, then that is an expensive issue that is causing your house to be a lot less energy efficient. 

Can condensation be bad?

Condensation is not nearly as big of an issue as steamed-up windows. Actually, it usually means your window is doing its job and keeping the cold outside or vice versa in the summer months. The only thing that condensation can do is build up mold around your windows which is easily cleaned. 

How to prevent your windows from steaming up?

There are measures to ensure you don’t have a steamed-up window in the future. Here’s a list to help prevent this occurrence. 

Be careful with your cleaning products

You want to be careful with harsh chemicals in your cleaning products. Over time this can lead to the deterioration of the seal of your window, which will inevitably lead to a steamed window. 

Reseal your windows

If you notice that it’s already a problem, try contacting your local window specialist, or watching a youtube video to figure out how to reseal your window properly. Re-sealing can be a messy job, so if you can afford it, I would recommend getting a quote and getting a professional to handle it. 

Keep them dry

Try keeping a dry cloth around and when you notice a build-up of steamy condensation on your windows, give your windows a pat-down. This keeps the moisture from building up and will also let you look out your window and see the view. It also prevents the moisture and mold build-up from that condensation from spreading around the house. 

Make sure your window fits properly

This is usually the job of the professional installing your window, but it’s good to take note of regardless. Make sure your window is properly installed into the hole (or window box) that it’s supposed to fit into. This is a way you can tell if your installer is at fault or not. Your window should fit snugly into the wall, with no cracks leaking cold air in. 

Call a professional

Calling in your local professional to learn his opinion is always a good idea. Not only can they give your good advice, but they can help you with preventative measures in the future. 

Replace the glass

If your window glass is steamed you can always buy a new window and replace your old one. This is a more expensive alternative but does the trick all the same. 

Bathroom fan

If you notice condensation on your bathroom window, make sure that you have the ventilation fan on which will not only prevent condensation but will also prevent mold build-up. 

When are you most likely to get steamed up windows?

Winter is the most common time of year to notice steamed-up windows. This is due to the heat being on inside your home, and it is a colder temperature outdoors. Single-glazed windows tend to get colder, with a potential of more condensation. 

Can steamed-up windows be bad for your health?

In terms of condensation building up on your windows, yes. Because of the extra moisture, you can be prone to a build-up of mold, which if not taken care of can lead to respiratory issues as well as spread. 

How do you prevent mold growth from steamed up windows?

There’s a simple way to fix this problem. Clean the mold away that has built up over time on your windows. Keeping a dry cloth around to wipe up the extra condensation build-up and get rid of any of that extra moisture can also prevent mold from growing and spreading within your household. 

How do you best deal with steamed-up windows if they are double glazed?
