Understanding the terms of your window warranty is essential for protecting your investment, especially in areas with high winds, snow, and rapid temperature changes that can affect window performance and longevity. Whether you have a casement window, double hung windows, or a sliding window, avoiding these common warranty-voiding mistakes will help you maintain your coverage and keep your home energy-efficient year-round.
1. Improper Installation by Unauthorized Contractors
Choosing the right installer for your new windows is a critical step. If you hire a contractor who is not certified or authorized by the manufacturer, your warranty may be voided. Renewal by Andersen® of Wyoming honors warranties only when installation is completed by its trained professionals. For example, an improperly installed casement window may not only result in poor insulation but also lead to costly repairs that are not covered by the warranty. Always verify that your window installer is authorized by the manufacturer, especially in areas with extreme seasonal weather, where improper installation can contribute to warping or water infiltration.
2. Modifying or Altering the Window Structure
Making changes to your windows, such as drilling holes, painting the frames with unapproved finishes, or applying aftermarket window films, can void your warranty. This is a common issue with double hung windows when homeowners attempt to improve privacy or change the appearance of the window. However, these modifications can affect the performance and durability of your replacement windows. Manufacturers provide specific guidelines for customization, and failing to follow them may result in the loss of warranty coverage.
3. Failing to Follow Care and Maintenance Instructions
Routine maintenance is essential for keeping your windows in excellent condition. Ignoring the manufacturer’s recommended cleaning methods or using harsh chemicals can damage window surfaces, seals, and operating hardware, especially on a sliding window that is exposed to seasonal dust and debris. Maintenance guidelines for custom windows typically recommend mild cleaning products and soft cloths. If there is evidence that abrasive materials or improper cleaners have been used, the warranty may no longer apply. Always follow the care instructions provided during installation and keep records of your maintenance whenever possible.
4. Environmental Damage and Storm Events
While Renewal by Andersen windows are designed to withstand demanding weather conditions, most warranties do not cover damage caused by natural disasters, including hail, windstorms, or flying debris. For example, a casement window with broken glass following a severe hailstorm is generally not covered under a standard product warranty. Likewise, damage to double hung windows caused by wind-driven debris typically falls outside warranty coverage. Taking preventive measures, such as securing outdoor items before storms, can help reduce the risk of weather-related damage.
5. Ignoring Signs of Wear and Delaying Repairs
Minor issues such as condensation between panes, sticking sashes, or small leaks should be reported to your service provider as soon as possible. Delaying repairs can allow the problem to worsen and may also affect your warranty coverage. Prompt attention to early signs of seal failure or hardware issues helps maintain your windows’ performance and supports continued warranty protection. Most warranties also require that inspections and repairs be completed by qualified professionals.
