What to Look for in a Knoxville Window Warranty

Planning to install new windows? Don’t forget to check the warranty. The extent of the warranty coverage will partly determine the returns on investment on your new units in the event they get damaged. 

What are the things you should look for in a window warranty? Renewal by Andersen® of Knoxville lists them in this post. 

The Type of Warranty 

There are two types of warranties: product and workmanship warranties. The former covers manufacturer defects while the latter covers installation errors. 

What to Look For in a Product Warranty  

What are the things you should look for in a product warranty? 

• Transferability – In case you’re planning to put your home up on the property market, you should look for sliding windows with a transferable warranty, which can be a selling point for prospective home buyers. As the name suggests, transferable warranties can be passed on to the next owner of your home. 
• The extent of the warranty coverage – Ideally, you should choose a window with a transferable and non-pro-rated product warranty. Pro-rated means the coverage for your windows decreases over time. 

What’s usually not covered by product warranties? Window damage stemming from “acts of God,” such as accidental fires and storms, lack of maintenance or any negligence on the homeowner’s part in general. 

What to Look For in a Workmanship Warranty

What are the things you should look for in a workmanship warranty? 

• Length of coverage – The effects of installation errors usually appear within the first or second year, so 5- or 10-year workmanship warranty should provide adequate protection for your bay windows. However, it would be better if you choose a window with a lifetime warranty. 
• Service call or diagnosis charges – Some contractors charge a fee for inspecting faulty windows and diagnosing issues. 
• List of window components that are covered – Not all window components may be covered under the warranty. 

What the Renewal by Andersen Warranty Covers

Renewal by Andersen offers warranties for its custom windows. Customers can enjoy a 10-year limited warranty on the frame, sash and locking mechanism of their Renewal by Andersen window and a 2-year limited warranty on the window installation. And homeowners who installed a Fibrex® window are eligible for a 20-year limited warranty on the Fibrex frame and glass. 

What Is Fibrex?

Fibrex is an exclusive composite that combines the best qualities of its two component materials: wood and vinyl. Fibrex has natural wood’s durability and insulative capabilities and retains vinyl’s minimal maintenance needs. Thanks to Fibrex’s durability, Fibrex sliding windows can hold the same amount of glass as a conventional window even though the window frames are much thinner, maximizing their glass area. Thanks to their durability, minimal maintenance requirements, and excellent insulative capabilities, Fibrex windows are ideal for homes in areas with moderate climates, like the Knoxville area. 

Here’s an overview of what a Renewal by Andersen transferable warranty covers:  

• Window glass – The transferable warranty covers manufacturer defects in factory glazed windows and the premature failure of the glass sealing for 20 years, starting from the date of the installation. If the glass sealing starts to fail within the warranty period, Renewal by Andersen will replace the defective window glass panes or repair the glass unit. Keep in mind special-order glazings, art glass, insulated art glass, impact-resistant glass and glass panes that weren’t installed by authorized installers aren’t covered. 
• Fibrex window components – Renewal by Andersen will repair Fibrex windows if there are any defects found within the 20-year warranty period. 
• Workmanship – The warranty covers installation errors made by factory-authorized contractors for two years, starting from the date of the original installation.
