What Factors Go Into the Cost of Window Replacement in Ontario?

There can be quite a range when it comes to the cost of window replacement in Ontario. There are a few major factors that go into the prices, including:


High performance materials (like hybrid material window frames or double and triple paned glass) will cost a little more upfront, but you’ll likely see lasting savings — both on energy bills and when you don’t have to replace the windows again in ten years.

Glazing and Coating

Getting windows with upgraded glazing or coating will add to the cost of windows. Even with the additional cost, windows with Low-E coating (transparent coatings put on glass panes to regulate heat passing through the window’s glass) continues to be a popular option due to the benefits it offers. These coatings help control or regulate the amount of heat windows absorb. This helps to generally improve the insulating properties of windows in the home.

Labour and Installation

Having a company or contractor install the windows will also impact the price. This price is variable, depending on the size of the project. It will likely cost more in labour to replace 20 windows than three or four. However, this cost is often worth it. You don’t have to worry about sourcing products, coordinating delivery, performing the labour, and so much more. It’s a cost that gives you peace of mind that everything will be done right the first time.

Can You Save Money by Doing Your Own Window Replacement in Ontario?

It’s worth cautioning that, for the most part, people assume this type of project is easier and less costly than it actually is. In a recent survey, over half of homeowners taking on DIY projects felt it was harder and took longer than anticipated. It was also revealed that over a quarter felt the project didn’t function well — 55% also felt their DIY efforts did not look good.

And most importantly: Around 17% found that the projects were more expensive than they expected.

So, DIY may not be the best route if you’re trying to cut costs. If you want to save money on window replacement in Ontario, here are some better tips.

Cost Saving Tips for Ontario Window Replacement

1. Use a Trusted Contractor or Window Company

2. Go Energy Efficient

Energy efficient windows may be a bit of a steeper up-front cost, but the long-term benefits will recoup the costs. You’ll find that you’re able to reduce the energy you use for peak cooling and heating, resulting in lower energy bills long term — anywhere from $125 to $340 annually.

3. Apply for the Canada Greener Homes Grant

Did you know the Canadian government actually offers grant and incentive programs to help with the costs of home upgrades? The Canada Greener Homes Grant program is meant to encourage Canadians to make energy efficient upgrades to their home by providing grants or loans that offset the costs. If you choose to go the energy efficiency route when upgrading as a way to save on expenses, this grant can get you some major savings.

4. Focus on Smaller Projects

There’s no reason you have to replace everything all at once. If there are certain windows that need replacing or upgrading, but you don’t want to splurge on replacing every window on your house, start small. If one or two windows on the front of the house are looking run down, replace just the front of the house to ensure you still have that curb appeal. If it’s a window at the back that needs repair and you aren’t quite ready for a full renovation, you can just replace the individual window. It’s all about making it a project that works for you and your budget.

Do You Need to Replace Your Windows Right Now?

On average, windows last anywhere from 15 to 30 years. But given the fact that Ontario is a four-season province, the elements can take quite a number on your home exterior — and this includes windows. Windows have to survive extreme temperatures that go from well below freezing and snowstorms in the window months, to 40 celsius heat in the summer.

But how do you know that your windows have been worn down? Here are a few signs that it’s time to think about exploring window replacement.

1. Utility Bills Are Getting Higher

Is it getting more expensive to heat or cool your house? This may be a sign it’s time for new windows. When windows start to deteriorate, they have a harder time holding in the heat. This means you have to use more heat to achieve the same level of warmth you have in the past — and that’s going to lead to some expensive utility bills.

2. You Regularly Feel a Cold Draft

If your windows are getting older, they may be letting more of that cold air from the outside in. Feeling a cold draft that has you reaching for the sweater or throw blanket more often than not is a pretty strong indicator you need window replacements. As your windows get worn down, they naturally let more cold air in from outside.

3. Visible Damage

You’ll likely be able to see visible damage as your windows age. Some of these signs include damaged or dented window frames, cracks or shatters in the glass, or struggling to open or close the windows.
