How to Get Affordable Windows that Last

At WindowStrong, we’re proud of the immense value that we provide for each and every one of our customers. But we’re equally as proud of product quality. After all, why would you want an inferior product?

Lifetime Warranty

All CDI windows sold through WindowStrong come with a simple, straightforward lifetime warranty against defects in materials or workmanship. If something happens during this time, then they will repair, replace, or refund you accordingly. Even better, this same warranty transfers to the next owner of your home for a period of five years. Whether or not you’re thinking about selling your home, this adds a ton of value when the time comes.

As part of our commitment to you, WindowStrong then takes this warranty one step further by providing a one-time, completely free glass repair or replacement. We understand that life happens, so we want to make sure that you love your new windows as long as possible.

Craftsmanship Warranty

Finally, WindowStrong also provides a one-year craftsmanship warranty against installation defects, which, in the unlikely event that it occurs, means we’ll have it fully resolved within 7-10 business days. Simply call our Installation Manager (206) 914-7075, and we’ll be onsite shortly.
