Finding the best window replacement warranty

The best window warranty in the business
There are many window replacement and installation companies in and around the Ottawa area that claim they have the best window warranty in the business. So what does this really mean?

If you are in the market for new windows, and you plan on living in your home for a while, then it’s essential that you look into the product and installation warranty’s offered by the companies that you are getting quotes from. Warranty periods should not be implied and sellers should not purposely neglect to inform you about important warranty information.

Many window companies in and around the Ottawa area claim to have the best window warranty in the business. Unfortunately, in terms of warranty the language used can be vague or suggestive and full of fine print that is difficult to interpret. Every window company is different and even companies that sell and install the same product will practice differing warranties.

What is the best warranty in the business?

In the window business, there are a number of window components as well as the installation that can be warrantied. In order to understand whether you are getting the BEST, you really need to know what the BEST would actually look like for each component. The list below indicates the typical maximum you might get for each these component.


  • Lifetime window warranty against all product defects that affect stated performance ratings at the time of manufacturing
  • Lifetime thermal pane replacement - gas leakage, cracks or obvious visual defects
  • Lifetime hardware replacement - screws, handles, gears, locks
  • All warranty registration will be done for you by the company that sells and installs the product

What is a lifetime Warranty?

There’s much confusion regarding what a lifetime warranty is and unfortunately to date, there are no government standards to police them. For most window manufacturers, a lifetime warranty (25 years) is an expression of their commitment to the quality and longevity of their products and their support to their customers, should an issue arise. Ask your window consultant for more information.

What’s not typically covered?

Damage to windows from acts of nature such as hail or extreme wind or accidental damage from flying projectiles.
