Best Time of the Year for Replacing Your Windows

You're considering replacing your windows, but you’re unsure of the ideal time to do so. Firstly, upgrading your windows is a great home improvement idea because it can not only boost overall indoor comfort but also make it highly convenient and easy for you to maintain energy efficiency.

Of course, the latter would depend on the type of window you choose and how professionally it is installed. Additionally, new windows can freshen up your home’s appearance both inside and outside. But here’s something a lot of homeowners don’t realize: when you replace them, it can be just as important as what you replace .

Certain seasons offer smoother installations and faster timelines. In fact, you may even get noticeably better prices. Others? Not so much. Whether your windows are leaking air, showing cracks, or simply overdue for an upgrade, we understand the importance of tackling the job at the right time to save stress and money.

Key Takeaways

• Spring and early summer offer ideal installation conditions with mild weather; however, it’s the peak season, which leads to higher demand and costs
• Fall is a great off-peak time with fewer scheduling conflicts and potential cost savings, plus it helps prepare your home for winter
• Winter can be a viable option with potential discounts, but cold weather may slow down installation and increase heating costs
• Summer is the least favourable time due to extreme heat, humidity, and higher utility bills from running air conditioning during installation
• You can time your window replacement to lead to energy savings, especially if you replace them before extreme weather seasons

When is it Time to Replace Your Windows?

Windows generally have a lifespan of 15 to 20 years, but factors like Ontario’s harsh climate can shorten this timeline. Yes, even with regular care. That’s because extreme weather conditions and wear and tear eventually catch up with windows, regardless of their durability. So, here are a few signs it might be time to replace them:

• Cracks, Warping, or Damage – If the window frame or pane is cracked, warped, or broken, it’s time to replace the window to maintain safety and insulation.
• Foggy Glass – Have you got fogging between window panes? It likely indicates a broken seal, which compromises the window’s insulating capabilities.
• Soft or Slimy Wood – Soft or decaying wood around the frame suggests moisture damage, which can lead to mould and structural issues.
• Hard-to-Operate Windows – Is it difficult to open or close windows? It could happen when the hardware gets stuck or swollen frames get in the way, which are signs of wear.
• Rising Energy Bills – If your heating or cooling bills have been increasing, it may indicate that your windows are no longer as efficient.

What’s the Right Time for Replacing Your Windows?

While there’s no single "best" time to replace windows, certain seasons can make the process easier and more cost-effective. But don’t worry, we have a breakdown of how different times of the year can affect your window replacement experience:

1. Spring & Early Summer – Ideal Conditions for Installation

Spring and early summer are typically the busiest times for window replacements. The weather is mild, which makes installation easier. Here are a few more reasons (with pros and cons):

• Optimal temperature for caulking – Caulking, which seals windows, works best when the temperature is between 5°c and 20°c. If it’s too hot, the caulk may run, while colder weather can cause it to harden too quickly.
• Smooth installation process – Temperatures are neither too hot nor too cold. This makes it easier for contractors to measure and install windows without requiring additional temperature control.
• Less stress on HVAC – During mild weather, you don’t have to crank up your furnace or air conditioning to deal with drafts (i.e., while the installation takes place).

Pros

• Comfortable installation conditions
• More availability of contractors
• Easy to manage your home’s temperature during installation

Cons

• Peak season, so there may be higher demand and longer wait times for installation.
• Prices may be higher during peak demand

2. Fall – Off-Peak Season with More Flexibility

Fall is often a great time to replace windows. That is, if you can wait and prefer fewer contractors. More importantly, it means potential cost savings. With the weather still mild but cooling off, it's an ideal time for installations. This is more favourable than the busy spring and summer seasons.

• Temperature considerations – Fall temperatures are generally favourable for window installation, and caulking can still set effectively.
• Less disruption – Since the season is off-peak, you’ll likely experience faster service with fewer scheduling conflicts.
• Energy savings before winter – If you replace your windows before the winter season, it will help seal your home and reduce heat loss when temperatures drop.

Pros

• Off-season discounts and better availability
• Less disruption during installation
• Preparing your home for winter

Cons

• As temperatures drop, you may need to run your furnace more frequently, which could increase heating costs during this time.

3. Winter – A Challenging But Feasible Time for Installations

While winter may not be the first choice for window replacement, it is still a viable option. In reality, it is favourable for homeowners to be in areas with milder winter conditions. Why? Consider these factors:

• Handling cold weather – Contractors can handle winter installations, but the cold may slow down the process. Caulking and window installation can be more challenging in freezing conditions, and you may need extra precautions to prevent drafts.
• Increased furnace usage – Since your home’s temperature will likely drop during the installation process, you may experience a temporary increase in heating costs until the new windows are fully installed and sealed.
• Discounts – Many companies offer discounts or promotions during the off-season to fill slower periods. This makes winter a potentially cost-effective option.

Pros

• Potential cost savings through off-season promotions
• Less competition for installers, resulting in faster service
• Some companies specialize in winter installations

Cons

• Increased heating costs due to temporary drafts
• Cold weather can make the installation process slower and more challenging

4. Summer – Not Ideal for Installation (but Still Possible)

Summer, especially the height of the season, is generally the least favourable time for window replacement. Why? Mainly due to the extreme heat. While it is possible to replace windows in summer, the heat can present some challenges:

• High heat and humidity – The extreme heat and humidity area is a no-brainer because they can affect both the contractor’s performance and the caulking. Excessive heat makes the caulk run, while high humidity interferes with proper sealing and curing.
• Air conditioning use – During the hottest months, you’ll likely have your air conditioning running. As a result, this could lead to higher utility bills due to drafts (i.e., open windows during installation).
• Long wait times – Summer is the peak season for home renovations, so contractors may be booked months in advance.

Pros

• Long days make for more working hours
• Fresh air and sunlight can make it a more pleasant time for contractors

Cons

• Increased costs and longer waiting times
• Extreme heat can affect installation conditions
• Higher utility bills due to air conditioning

Regional Climate Variations and Best Timing

The best time to replace windows can also depend on your specific location in Canada. We usually discuss the following considerations based on regional climate differences with our clients:

Cold Regions (e.g., Alberta, Manitoba)

Winter can make window replacements tricky with sub-zero temperatures. The best time to schedule an install is during the spring or fall. That’s when the weather is milder and more manageable for both you and the contractor.

Milder Coastal Regions (e.g., British Columbia)

If you’re in a coastal area, you have more flexibility, but keep an eye on the weather. Rainy seasons can cause delays, so spring and fall are generally considered the safest times for a smooth installation.

Humid Summer Regions (e.g., Ontario, Quebec)

In areas with high summer humidity, the hot and sticky air can make window replacements harder. Spring and fall are also your best options, as they offer more comfortable working conditions for contractors.

Seasonal Price Fluctuations and Cost Considerations

Don’t forget that pricing for window replacement can also vary throughout the year. But how will different seasons impact costs? Here’s how!

• Peak Season (Spring and Summer) – These are the busiest seasons for window replacements, resulting in higher demand. Contractors may charge more, and you may have to wait longer for installation. However, if you want to get it done when the weather is ideal, this is when most people tend to book.
• Off-Season (Fall and Winter) – The off-season can actually be the best time for saving money. Contractors are often offering discounts or promotions to fill their schedules, making it a more cost-effective time to replace your windows. If you're not concerned about the weather, this could be a great opportunity to snag a deal.
• Supply Chain Fluctuations : Monitor material prices, such as those for glass and frames. Costs can fluctuate depending on seasonal demand, so it’s worth checking for any price increases or special offers before you commit.

Financial Benefits of Replacing Windows by Season

Note this: replacing your windows before extreme weather seasons, like summer or winter, can save you significant energy costs. New windows, especially energy-efficient ones, will help you reduce heating and cooling expenses as they improve your home’s insulation during harsh weather conditions.

Furthermore, some Canadian provinces offer government rebates or incentive programs to encourage homeowners to replace their windows with energy-efficient models. You can look up such incentives, which might be available during certain times of the year where you live. Be sure to keep an eye out for them when planning your window replacement.

Quick Tips for Scheduling Your Window Replacement

Therefore, we conclude this comprehensive blog post with a list of quick tips for scheduling your window replacement. Here’s what you should note:

• If you’re replacing your windows during peak season, book your contractor well in advance
• Remove any obstacles around your windows and clear a path for the installers
• If you’re open to replacing your windows during the off-season, you may find discounts or promotional offers

Conclusion

When it comes to replacing your windows, the timing really does matter. If you’re looking for a smooth process and fewer delays with the best chance of saving, then aim for fall or spring. That is a smart move and something most homeowners who do their homework prefer.

You’ll get mild weather, quicker service, and even some potential cost savings. But, if you’re looking to score a deal, winter can be a hidden gem – especially if you're flexible.

Whatever time of year you pick, just remember that replacing your windows at the right time can save you money. More importantly, it will help ensure your home is ready for whatever weather is coming next.
