5 Solid Reasons Why Window Replacement Is a Must-Do

By Editorial Team

When you move into a new house or apartment, you hope that your home improvements will last for many years. However, as time passes, it often feels like every part of your home needs renovating almost overnight. Not only is this costly, but it's also time-consuming and sometimes difficult to replace or fix the issues that arise.

Additionally, advancements in home renovation technologies occur every year, meaning that your 10-year-old installation may no longer be as effective today. This is particularly true for old windows, which play a crucial role in keeping our homes warm year-round.

This is especially important in areas with harsh winters. In cities like Ottawa and Quebec City, replacing windows should be a priority. If you notice rising energy bills and see that your windows no longer contribute to the aesthetic or comfort of your home, it’s time to consider replacements that will restore warmth and comfort.

While it’s easy to overlook the poor condition of your windows, we’ll explore the reasons why replacing them is essential.

Factors to Pay Attention To

Rot or Warping  

Whether you have wooden or PVC windows in your home, both types are prone to damage over time. Severe weather conditions place significant strain on window frames, causing small issues that can escalate into major problems within a few years.

Wooden window owners face particular challenges, as rot, once it starts, is impossible to fully stop. While there are products marketed as solutions, they are generally short-term fixes. Cleaners may offer temporary relief, but ultimately, they fail to prevent further damage. Over time, you'll notice your windows becoming harder to open and close.

For PVC windows, hot and sunny weather is the primary culprit. High temperatures can cause the frames to warp, leading to issues such as heat leakage during colder months, cracks, and condensation. These problems can quickly worsen if not addressed.

Rise in Energy Bills  

First and foremost, windows play a crucial role in keeping our homes warm. When they are in good condition, there’s no need to rely on multiple space heaters during cold weather. Central heating is usually sufficient. However, when windows deteriorate, the only option is to invest in heat-generating devices, which can be costly.

Most importantly, these additional devices contribute to rising energy bills. With electricity prices being unpredictable, it’s unwise to add more gadgets that increase costs. A smarter choice would be to invest in new windows that eliminate the need for extra space heaters.

To assess the condition of your windows, start by reviewing your heating bills and how effectively your home stays warm. Also, stand near your windows—if you can feel a breeze, it’s a clear sign they are no longer performing their intended function.

Challenges with Opening and Closing Windows

Windows provide comfort and convenience in our homes. On a hot day, you can open a window to let in fresh air, and on a cold day, you can close it to keep warmth inside. These simple actions should never be a challenge. However, as windows age, they can bring more discomfort than relief.

The reasons behind these challenges depend on the type of material your windows are made of. Over time, wooden windows may begin to rot or warp, while shifts in the foundation of your house can cause windows to no longer fit properly. This can occur a few years after moving in. It's not necessarily a fault of the windows, but rather a result of natural wear and physical changes. In any case, reliable windows can’t be expected to last indefinitely—replacement becomes essential.

Street Noise Becomes Disruptive

Another important function of windows is soundproofing. Families who build homes near busy roads often invest in high-quality windows to block out street noise. Modern windows are designed to eliminate much of the outside sound, making it much more comfortable to live in the house. For some, choosing a location far from busy roads isn’t always an option.

However, if your windows provided peace and quiet in the past, but now you feel like you’re living on the street even with them closed, it’s a clear sign that replacement is necessary. Once new windows are installed, you’ll be able to enjoy the tranquility of your home, even if it’s near busy roads, because the noise will be virtually eliminated.

Formation of Condensation

Living in a beautiful landscape with sunlight streaming through your windows can be truly satisfying. However, you might notice condensation forming on your windows throughout the day. While it may seem harmless at first, and easy to wipe away with a cloth, it’s actually a warning sign that mould could soon develop inside the window frame.

This isn’t just an unpleasant issue—it’s also a health hazard. If mould spreads, it can become difficult to eliminate, and over time, it can affect your airways. You may experience frequent headaches, fatigue, sleep disturbances, and a weakened immune system. In short, every member of the household is at risk. Investing in window replacement isn’t just about improving your home—it’s also an investment in the health and well-being of your family.

In Conclusion  

Old windows can create numerous problems for homeowners. Over time, they deteriorate for various reasons, leading to issues like rot, warping, and rising energy bills. They may no longer keep your house warm, and the insulation they once provided becomes ineffective. Most importantly, if mould starts to develop, health issues can follow. Therefore, don’t ignore the need for window replacement—it can bring significant benefits to your home and family in many ways.
