A window warranty offers protection and peace of mind, ensuring that you are covered in case of any defects or issues. This blog post will guide you through the key aspects to look for in a window warranty, helping you make an informed decision.

What is a Window Warranty?

A window warranty is a written guarantee provided by the manufacturer or installer that outlines the terms and conditions under which the windows will be repaired or replaced if they fail to perform as expected. Here are the primary elements to consider:

Coverage Duration

The duration of the coverage is one of the first things to check in a window warranty. Most warranties offer different coverage periods for different components of the window. Typically, you will find:

  1. Lifetime Warranty: This often covers the window frame and sash for the life of the product, but be sure to read the fine print to understand any limitations.
  2. Limited Lifetime Warranty: Similar to a lifetime warranty but with certain restrictions and exclusions.
  3. 10-20 Year Warranty: Often applies to insulated glass units (IGUs), which are prone to seal failures over time.


A transferable warranty can be a significant advantage if you plan to sell your home. This means that the warranty can be transferred to the new owner, adding value to your property. Check the terms to see if there are any fees or limitations associated with transferring the warranty.

Key Features to Look for in a Window Warranty

Comprehensive Coverage

A good window warranty should offer comprehensive coverage, including:

  1. Frame and Sash: Protection against warping, cracking, and other defects in the frame and sash materials.
  2. Glass: Coverage for issues like seal failure, which can cause condensation between the panes, and breakage.
  3. Hardware: Coverage for the functionality of locks, latches, and other hardware components.

Labor and Installation

Some warranties only cover the materials but not the labor involved in repairing or replacing faulty windows. Look for a warranty that includes labor coverage, as the cost of labor can be significant.

Exclusions and Limitations

All warranties come with exclusions and limitations. Common exclusions include:

  1. Normal Wear and Tear: Damage that occurs as part of normal usage is typically not covered.
  2. Improper Installation: Issues resulting from poor installation practices are often excluded.
  3. Acts of Nature: Damage from natural disasters like hurricanes or earthquakes may not be covered.

Process for Filing a Claim

Understanding the process for filing a warranty claim is essential. Look for clear instructions on how to file a claim, including the required documentation and the timeline for resolution.

Additional Considerations

Manufacturer Reputation

The reputation of the manufacturer can provide insight into the reliability of their warranty. Research customer reviews and ratings to ensure you are dealing with a reputable company.

Local vs. National Warranties

Some warranties are backed by local companies, while others are supported by national manufacturers. A national warranty may offer broader coverage and more resources for fulfilling claims.

In Summary

Choosing the right window warranty involves careful consideration of coverage duration, transferability, comprehensive coverage, labor and installation inclusion, exclusions and limitations, and the claim filing process. Additionally, evaluating the manufacturer’s reputation and understanding the differences between local and national warranties can help you make a well-informed decision.
