How to choose a replacement window company

The right replacement windows for your home depend on your home’s aesthetic, location and energy efficiency needs. Choosing an Energy Star partner company or Energy Star-certified windows may help reduce your ongoing electricity costs.

How window warranties work

Window warranties vary depending on the company and can include (or not include) parts, labor, defects, accidental breakage, film, seals and frames. Here are a few common options:

• Limited lifetime warranty covers aesthetic and performance defects, but may only cover replacement parts, not labor or installation. For example, if a window frame is no longer sliding correctly, your warranty may cover a replacement.

• Lifetime warranty does not always mean “for life.” This warranty is meant to cover the manufacturer’s expected lifetime of the window, which can be as low as three years or as high as 20 years or more. Typically, glass is covered for the longest period of time, non-glass parts are covered for less, and hardware, such as locks, is covered for the least time.

• Transferable warranty allows you to transfer your window coverage to a new homeowner. If you plan to sell your home at some point, especially within the next 20 years, a company that offers transferable window warranties may be a helpful choice.
