How much does it cost to replace a window in Toronto?

Replacing windows doesn’t just save you money on energy, it also increases the value of your home. Most window replacements will cost between $100 and $650 depending on the size and materials needed. Depending on the scope of your project there are also government grants available to offset the cost of your new windows.

Should I replace all my windows at once?

If you need to replace one window, then it’s important to take care of it as soon as possible. Windows that are not sealed properly or are broken can cost you money in heating and energy. If you have an older home and your windows are 25 years or old, it may be better to replace your windows all at once. This may allow you to enjoy additional savings and will save your energy bill.

What is the best time to replace my windows?

The best time of year to replace windows is in the late spring and early summer. This means there is less chance of rain which may delay an install and you don’t have to worry about excessive heat or cold creeping into your home during the installation process.

Are your windows energy efficient?

All our windows meet the Canadian Standard Association guidelines. We offer the latest in EnergyStar-rated window technology that can help you save money and protect your home from uncomfortable drafts. Replacing just one window can save you $100 to $500 annually in energy costs.

Do you offer a lifetime warranty on your windows?

We stand behind all our window and door products. That’s why we offer lifetime transferable warranties with the most extensive coverage options for all our products.
