“A window is more than just glass—it’s your view, your light, and your shield from the elements.” This statement is generally used to describe the role of windows in our buildings and cars. Which is true too, as it really protects us from a lot of things, which include chilly winds as well. 

But do you know that these windows get so much while protecting us, and the change in seasons can cause even more damage to them? And later, this thing will affect your comfort, efficiency, and wallet. 

In fact, up to 30% of your home’s heating energy can be lost through these windows due to air leaks, broken seals, and poor maintenance. (Source: The U.S. Department of Energy) I know you must be thinking about what’s next.  

So let’s come to the point now. No, don’t worry, I am not going to ask you to replace your window for every problem. But in this guide, we will also talk about how you can restore your window function, appearance, and efficiency with the right approach and a few pro tricks. 

It covers everything you need to know. Let’s get started.

Replacing Broken or Foggy Glass

If your window has cloudy panes, chips, and cracks, and you think it is just spoiling your view, you are wrong. It is doing a lot more, and one of those major effects is reducing its energy efficiency. The reason behind this is a failed seal on your windows.

Thinking of fixing it with DIY? Don’t, because small cracks can be temporarily repaired by clear tape or sealant, but for permanent repair, glass replacement is important.

For curing this, you can hire window glass professionals in Denver, CO, as that will give you clean and long-lasting results, especially if you have insulated glass units (IGUs). 

Pro Tip: Modern glass replacement now comes with energy-efficient coatings or better insulation. Which is another great chance and reason to update

Did you know?
The first known use of glass windows was by ancient Rome around 100 AD. Before that, people were using animal hides, cloth, or thin pieces of translucent stone like alabaster as windows!

Sealing Drafts and Improving Energy Efficiency

You would never have thought in your life that windows can be a reason behind your high electricity bills. Yes, if you have a leaky window in your home, it is letting your cooled or heated air escape, forcing your systems to work harder. 

In fact, Energy Star has estimated that the replacement of old windows with ENERGY STAR-certified ones can lower people’s household energy bills by an average of 12% nationwide.

Here are some tips for you to spot it.

• Run your hand around window edges on a breezy day to see if the air passes.
• Hold a lighted candle near the window frame, and if it flickers, then there is movement around. 

How can you fix it?

• Apply weatherstripping around loose areas.
• Use caulk for immovable joints and gaps.
• For large cracks, use foam sealant.

Fixing Stuck or Hard-to-Open Windows

Windows that don’t slide smoothly are really frustrating, and it happens mainly because of three reasons: dirt buildup, warped frames, or swollen wood. Let’s come to the solutions directly:

• Clean around the windows thoroughly with a brush or vacuum.
• Apply a silicon-based lubricant (do not use petroleum-based as it will attract more dust)
• For wooden windows, apply the paint that can seal the sash and frame together.

After doing all this, if the problem still persists, then the issue is about alignment and hardware. In that case, it’s better and safer to go to a professional directly.

Maintaining Your Windows for Long-Term Performance

We all know that “prevention is always better than a cure,” and it’s relatable in this case, also. Prevention can help you avoid costly repairs and replacements. That too, with just a little routine care of your windows. Here is a maintenance checklist for you:

• Clean the grasses and side frames with a gentle solution monthly
• Check for seals and caulking seasonally
• Do the oiling of the moving parts twice a year
• Paint and refinish your wooden frames every few years to prevent rotting and swelling.

These steps will extend the lifespan of your windows while supporting overall home effectiveness. At the end, remember that the key is to act early before small problems turn into costly repairs.
