7 Signs It's Time to Replace Your Windows

Does this sound familiar? You turn up the heat, and just minutes after your furnace stops running, you’re already reaching for your blanket. Or maybe your windows are constantly fogged with water droplets, making your view of the outdoors murky. Worst yet, maybe you feel a slight breeze or a pocket of cold air while standing by your fully closed window in colder months. If you’ve had moments like these, it may be time to upgrade your old windows.

Windows aren’t meant to last forever. Over time, wear and tear, shifting temperatures, and general aging can cause window problems. As a homeowner in British Columbia, especially with our variable weather conditions, recognizing when it’s time for a window replacement is key to maintaining your home’s comfort, energy efficiency, and value.

At Jesko Windows & Doors, we know the common window problems BC homeowners face and the telltale signs indicating when replacement windows are due. Today, we’re sharing seven of these signs to help you determine when to upgrade your old windows.

Recognizing the Signs: 7 Signs You Need New Windows

These key signs impact your home’s comfort and can be dangerous, in some circumstances. We recommend that you regularly inspect your windows for the issues below, especially if your windows are over 20 years old or you aren’t sure when they were installed. 

1. Drafts and Air Leaks 

If you feel a breeze even when your windows are shut tight, it's time to investigate. While you may be able to sense a change in temperature using your hands, you can double-check for drafts by holding an incense stick or candle near the window edges. If the smoke or flame moves, outside air is coming in. 

Drafts can significantly raise your heating bills and create inconsistent temperatures throughout your home. New windows offer improved seals and energy-efficient features that help eliminate these air leaks.

2. Condensation Between the Panes 

Foggy windows that block your view are not only annoying but also a serious sign that replacement is overdue. If you notice moisture or condensation trapped between the panes of glass, the window seal has likely failed. This means the insulating gas has escaped, reducing your window’s ability to keep heat in winter and summer and allowing moisture to collect. 

Excess moisture can lead to mould growth, which can be dangerous to members of your household. If you notice your windows are foggy, it’s a clear sign they need replacing.

3. Difficulty Opening and Closing 

Windows that stick, are hard to open, or won’t stay open can be frustrating and even dangerous. This is a sign of aging hardware or frame warping and poses a safety risk during emergencies, such as fires, where easy emergency escape is essential.

4. Rotting or Damaged Frames 

Wooden frames that feel soft, show signs of crumbling, or have visible rot should be addressed right away. Vinyl and aluminum frames can also warp or crack over time. These issues reduce the structural integrity of your window and compromise insulation. Replacing them both improves function and prevents further damage to walls and window sills.

5. Increased Energy Bills 

Have your heating or cooling costs been creeping up with no explanation? Old or inefficient windows are likely the cause. Without proper insulation, your HVAC system must work harder to maintain comfortable temperatures. Investing in energy-efficient replacement windows can significantly reduce your energy bills and carbon footprint.

6. Outside Noise Penetration 

If you’re hearing more street noise than usual, your windows may no longer be blocking sound effectively. Modern replacement windows offer better sound insulation, helping create a quieter, more peaceful indoor environment.

7. Visible Damage

Cracked glass, broken locks or latches, and peeling paint are obvious signs of aging. Beyond hurting your home’s appearance, these issues reduce the functionality and security of your windows. Damaged windows also contribute to water leaks and drafts.

If your windows are displaying any of these signs, get in touch with a window expert. 

The Benefits of Window Replacement

Now that you can recognize the most important window problems and when it’s time to upgrade, here are some essential ways window replacement can improve your home:

Improved Energy Efficiency 

Modern windows are designed with energy savings in mind. Double or triple glazing and insulated frames reduce heat transfer and help maintain a consistent indoor temperature.

"When we install replacement windows, our clients are surprised at just how quickly they notice a drop in their energy bills. It's one of the most rewarding upgrades you can make to your home."

- Jason, Co-Founder of Jesko Windows & Doors

Increased Comfort 

New windows eliminate drafts, prevent hot and cold spots, and reduce outside noise. The result is a more comfortable home year-round, with less strain on your heating and cooling systems.

Enhanced Home Value 

Window replacement is one of the most valuable home improvement investments you can make. New windows offer curb appeal and communicate to future buyers that a home is taken care of. Plus, state-of-the-art, energy-efficient windows are a selling point for buyers, who want to know that they won’t have to do any major replacements in the next few years. 

"Upgraded windows can completely transform a home’s exterior and boost resale value. It’s an investment that pays off visually and financially."

- Jason, Co-Founder of Jesko Windows & Doors

Reduced Maintenance

Many new windows are made from durable materials, like uPVC, that require little to no maintenance. Modern finishes resist peeling, cracking, and fading, and can be cleaned using just a cloth and soapy water. 

Enhanced Aesthetics 

While a fresh coat of paint can make all the difference to a room, your windows offer a great opportunity to refresh your home’s look, both inside and out. This is especially true if you moved into an older house. Replacement windows are a chance to make your home truly yours!

Choosing the Right Replacement Windows

While selecting the right style to match your home is important, there’s more to consider when upgrading your old windows. 

Materials

You’ll need to choose a material for your replacement windows. uPVC, wood, and aluminum each offer different benefits in terms of insulation, durability, cost, and aesthetic appeal. Different glazing types, like double-pane and triple-pane, are another important factor when considering energy efficiency.

Styles

When selecting replacement windows, there are many styles to choose from. Casement, double-hung, and sliding windows each suit different needs. At Jesko Windows & Doors, we specialize in tilt-and-turn windows, which provide a number of benefits and features that make them stand out. 

Budget

Quality replacement windows are a worthwhile investment that can save you money in the long term. We pride ourselves on providing premium windows at an affordable price for Canadian households.

Addressing Your Questions About Window Replacement

How do I tell if my windows need replacing? 

Look for drafts, condensation between panes, frames that are hard to open, visible damage, and rising energy bills. These are all clear signs that it's time for replacement windows.

What is the average life of house windows? 

Most windows last 15–30 years, depending on materials, quality, and maintenance. If your windows are over 20 years old, it may be time to replace them.

Should I replace my 20-year-old windows? 

Yes, especially if you’re noticing drops in temperature, condensation, wear and tear, or other performance issues. Even if they appear intact, older windows typically lack modern windows’ energy efficiency and features.

Do windows really need to be replaced? 

In many cases, yes. While some minor issues can be repaired, complete replacement ensures better performance and is often more cost-effective in the long term.
