Typical warranty on new residential windows

Repairing Windows After Warranty Period

• Frame and Sash Warranty: Many window manufacturers offer warranties on window frames and sashes that last between 10 and 20 years. Some high-quality or premium brands may even offer lifetime warranties for as long as you own the home.
• Glass Warranty: The insulated glass unit (IGU) warranty typically covers seal failure, which can lead to fogging or condensation between the panes. The standard warranty duration for the glass component often ranges from 10 to 20 years.
• Hardware Warranty: The hardware, which includes components like locks, hinges, and handles, generally has a shorter warranty period compared to frames or glass. It might range from 2 to 10 years, although some premium brands might offer longer warranty periods.
• Labour and Installation: Some manufacturers may provide a separate warranty covering labour and installation. This is typically shorter, ranging from 1 to 5 years. It’s crucial because if there’s a manufacturing defect, but the window was also improperly installed, the manufacturer might not honour the warranty.
• Transferability: Some warranties are transferable to a new homeowner if the property is sold, which can be a selling point. However, the terms of transferability can vary. Some may continue the complete warranty for the new owner, while others might pro-rate or reduce the coverage period after transfer.
• Exclusions and Limitations: Almost all warranties will have exclusions or limitations. For instance, damage due to misuse, neglect, accidents, natural disasters, or improper installation might not be covered. It’s essential to read the warranty carefully to understand these details.
• Additional Warranties for Specific Features: Some windows may have unique features or coatings – for instance, UV coatings, impact-resistant treatments, or other enhancements. These might come with their separate warranties.

It’s important to note that while a warranty provides a measure of protection and indicates the manufacturer’s confidence in their product, it’s not a guarantee of the product’s lifespan. Always read the fine print to understand the terms, conditions, exclusions, and the process for making a claim. When comparing window options, consider the warranty duration and the manufacturer’s reputation.
