Window warranties protect consumers from expensive repair or replacement costs when a window malfunctions or if there is an issue with the installation. A warranty eliminates additional expenses and keeps you from paying more than have to if a manufacturer or an installer does not perform as advertised.

What to Consider in a Warranty

Before you purchase a warranty for your windows, you'll need to ask the professional window installer some essential questions such as:


●        Do you offer a warranty on all your windows?

●        When does the warranty expire?

●        Does the warranty cover all parts and labor?

●        Do you offer both limited and full warranties?

●        How do I register for the warranty? Can I re-register once the warranty expires?

●        How soon will you replace or fix the windows under warranty?

●        Can I pass the warranty along to future other homebuyers?

Why Your Contractor Should Offer a Warranty

If your contractor does not offer a manufacturer or installation warranty warrant, you may want to consider hiring a different window contractor—be sure to ask this question before reaching a signed agreement of work with your contractor.


A warranty signifies that a contractor can guarantee both the quality of the product and the quality of their work. Even the best contractors make mistakes from time to time. The warranty holds the installer accountable for their mistakes or product defects.


Keep in mind, there is a difference between a manufacturer warranty and a labor warranty. The contractor, however, often packages both into a single warranty.

Warranty Duration

The lifetime of warranty differs by product, brand, or manufacturer. Some manufacturers may offer a lifetime warranty, meaning they are valid for either the lifespan of the product or the expected lifespan of the product. Others may only be valid for one, five, or 10 years, while others may last as long as 20.


In most cases, you have the option to purchase different warranties depending on what they cover and how long they last. You may also have the option to purchase additional coverage once the warranty expires.

What the Warranty Covers

One of the most critical components of a warranty is what it covers. You should never assume that it is going to cover all manufacture parts and labor. Manufacturers or window contractors will often choose what they will cover in a warranty and under what conditions. For instance, they may make provisions for owner negligence or careless behavior when opening or closing a window. Also, some parts will wear out with regular use and may not be covered under warranty.


IN essence, warranties cover defects or things that occur that would not otherwise occur in normal circumstances.

Labor Warranties

Labor warranties differ from manufacturer warranties in that they cover the installation and not the product (although they are occasionally related). IN a labor warranty, the contractor agrees to come back and correct a mistake with the original installation. If you believe that a window malfunction was due to an installation mistake and not manufacturer warranty, either the manufacturer or the installer may need to establish who is liable for damage.
