If you’re thinking about replacing the windows in your Ottawa home, you may be wondering whether there’s a particular time of year when you can get a better price.
The short answer is yes—late fall and winter can often be the most affordable times to replace windows.
Window companies tend to be busiest during the spring and summer renovation season. Once the weather gets colder and demand slows down, homeowners may find better scheduling availability and, depending on the company and current promotions, more competitive pricing.
However, price isn’t the only consideration. The best time to replace your windows depends on your budget, the condition of your existing windows, your preferred installation date and how quickly you want to improve your home’s energy efficiency.
Here’s what Ottawa homeowners should know before scheduling their window replacement.
When Is the Cheapest Time to Replace Windows?
For homeowners looking primarily for the best opportunity to save, late fall through winter is generally worth considering.
In Ontario, window installation demand typically increases during the spring and summer months. The October through March period can be quieter, which may provide homeowners with more flexibility when choosing an installation date. Some window companies may also offer seasonal promotions during slower periods.
That doesn’t mean every company charges less during winter, however.
Window pricing depends on several factors, including:
- The type and size of the windows
- The number of windows being replaced
- Glass and energy-efficiency options
- Installation requirements
- Customization
- Labour
- Current manufacturer promotions
- The contractor’s seasonal schedule
For that reason, it’s better to think of winter as a potential savings opportunity, rather than assuming that every winter window replacement will automatically be cheaper.
Why Can Winter Be a Good Time to Replace Windows?
The biggest reason is simple: demand tends to be lower.
Most homeowners start thinking about home improvement projects when spring arrives. Window companies can become increasingly busy through spring and summer, with homeowners competing for installation dates.
During the quieter months, contractors may have more availability.
That can mean:
More Flexible Scheduling
You may have an easier time getting the installation date that works for you.
Instead of waiting several weeks during peak season, you may have more scheduling options during the off-season.
Potential Seasonal Promotions
Some companies and manufacturers offer promotions during slower periods to keep installation crews busy.
These promotions can vary from year to year, so it’s always worth asking what offers are currently available.
Faster Project Planning
If you’re ready to move forward, having more installation availability can make it easier to get the project scheduled.
This can be particularly helpful if you have windows that are already showing signs of failure.
Is Summer the Most Expensive Time to Replace Windows?
Not necessarily, but summer is typically one of the busiest periods for home renovations.
The combination of warmer weather, longer daylight hours and homeowners wanting to complete projects before winter means window installers can be in high demand.
That can result in:
- Longer wait times
- Fewer available installation dates
- Less flexibility with scheduling
- Potentially fewer promotional opportunities
Current Ontario window industry information identifies May through September as a particularly busy period for window installation, while the October through March period can offer more favourable scheduling and pricing opportunities.
If you know you want new windows before winter, don’t wait until late summer to start getting quotes.
What About Spring?
Spring can be an excellent time to replace windows, but it isn’t necessarily the cheapest.
As temperatures rise, homeowners begin noticing problems that became apparent during winter:
- Drafty windows
- Condensation
- Cold rooms
- Damaged weatherstripping
- Difficult-to-open windows
- Foggy glass
- Increasing heating and cooling costs
This can create a rush of demand.
Spring does have some advantages, though. Moderate temperatures can provide comfortable working conditions, and homeowners have plenty of time to improve their windows before the next winter.
If price isn’t your only concern, spring can be an excellent time to get the project started.
Is Fall a Good Time to Replace Windows?
Fall may be the best overall compromise for many Ottawa homeowners.
Temperatures are generally more comfortable than the middle of winter, and homeowners can have their new windows installed before the coldest weather arrives.
Fall can also be less hectic than the peak summer months.
If you’re planning to replace your windows before winter, it’s smart to start the process during the summer—or even earlier. Custom windows need to be measured, ordered and manufactured before installation.
Waiting until November to start looking for windows may mean you’re competing for the remaining installation dates.
Can Windows Be Installed During an Ottawa Winter?
Yes.
Professional window replacement can be performed during winter, provided the installation company uses appropriate procedures and materials for cold-weather conditions.
Installers generally work on one window opening at a time rather than leaving the entire house exposed to the outdoor temperature.
Winter installation does require additional planning, particularly during periods of extreme cold, snow, ice or strong winds.
For Ottawa homeowners, this means winter shouldn’t automatically be ruled out.
If your existing windows are performing poorly, waiting until spring simply because it’s warmer may not be the best financial or practical decision.
Should You Wait Until Winter to Save Money?
Not always.
If your windows are already failing, waiting several months could cost you more than any potential seasonal discount.
For example, if you have:
- Significant drafts
- Water entering around the window
- Condensation between panes of glass
- Rot or deterioration around the frame
- Windows that no longer open or close properly
- Broken or damaged glass
- Serious difficulty keeping rooms comfortable
it may make more sense to replace them when the problem becomes apparent.
The cheapest time to replace a window isn’t necessarily the time when the price on the quote is lowest.
The real goal is to get the best combination of product, installation quality, warranty and overall value.
How to Get the Best Price on Replacement Windows
Regardless of the season, there are several things Ottawa homeowners can do to keep their project affordable.
1. Get Multiple Quotes
Don’t choose a window company based solely on the first quote you receive.
Compare the actual products and installation services being offered.
2. Compare the Window Specifications
Two quotes can look very different because they may include different:
- Window styles
- Glass packages
- Energy-efficiency ratings
- Frame options
- Hardware
- Installation methods
- Warranty coverage
The cheapest quote isn’t necessarily the best value.
3. Replace Multiple Windows Together
If several windows need replacement, ask whether completing them as one project provides better overall value.
You may be able to reduce duplicated labour and installation costs compared with completing several small projects over a number of years.
4. Ask About Seasonal Promotions
If you’re shopping during late fall or winter, ask your window company whether there are any current manufacturer or seasonal promotions.
Don’t assume a discount is available—but don’t be afraid to ask.
5. Plan Ahead
One of the best ways to get a good price is simply to avoid being in a rush.
Start researching companies and products before your windows become an emergency.
This gives you time to compare quotes, investigate different window options and choose an installation date that works for you.
What Is the Best Month to Replace Windows in Ottawa?
There isn’t one specific month that is guaranteed to have the lowest price.
However, if your main goal is finding the best opportunity for off-season pricing, late fall and winter are the periods I would investigate first.
If your priority is a combination of comfortable installation conditions, reasonable scheduling and preparation for winter, early fall can be an excellent choice.
And if your windows are already failing, the best time may simply be as soon as you can find a qualified installer and the right product for your home.
The Cheapest Window Isn’t Always the Best Window
It’s tempting to focus entirely on the price when replacing windows.
But your windows will be part of your home for many years.
A cheaper window that doesn’t provide the energy efficiency, durability, appearance or warranty you want may not be a bargain in the long run.
Instead, compare the total value of the project.
Consider the window quality, energy efficiency, installation, warranty and reputation of the company installing them.
That’s how you can avoid turning a low initial price into an expensive mistake.

Frequently Asked Questions
What is the cheapest month to replace windows?
There isn’t one guaranteed cheapest month, but late fall and winter are generally worth considering because demand for window installation tends to be lower. Seasonal promotions may also be available during slower periods.
Is it cheaper to replace windows in winter?
It can be. Some contractors offer more competitive pricing or promotions during the winter when demand is lower. However, pricing varies by company, product and project, so it’s important to compare quotes rather than assuming winter will always be cheaper.
Is fall a good time to replace windows?
Yes. Fall can provide an excellent balance between comfortable installation conditions, availability and preparation for winter. It’s also a good time to improve your home’s energy efficiency before the heating season.
Can windows be replaced in the winter in Ottawa?
Yes. Professional window installers can replace windows during winter using appropriate installation procedures and materials. Extremely cold, snowy or windy conditions may affect scheduling.
Is it better to replace all my windows at once?
If your budget allows, replacing multiple windows during one project can be more efficient than completing several smaller projects over time. Ask your window contractor whether there is a pricing advantage to completing the work together.
Should I wait for a winter sale to replace my windows?
Not if your existing windows are already failing. Drafts, leaks, damaged frames, failed seals and operational problems can become more expensive if ignored. If your windows need replacement, focus on finding the right combination of product, installation and price rather than waiting for a particular month.
