The best window warranty in the window business

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 warranties 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 details.

Many companies claim to have the best window warranty in the business. Unfortunately, the warranty language used can be vague or inferential 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.

It’s in your best interest to scrutinize the warranty information that you are provided with and to ask lots of questions when dealing with a window company. Below are some points to consider when looking at warranty information.

What is a lifetime warranty?

Ask your window consultant for more information.

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