When you buy a product from Window Works, we want you to have peace of mind even after the purchase is made. That is why our windows and doors are covered by industry-leading, limited warranty. Our products inspire better ways of living for our customers.


Most of the windows and doors supplied by Window Works are made by Marvin. This means that every Marvin product you buy from us comes with an unbeatable Marvin warranty that covers any defects from manufacturing, materials, and workmanship for ten years. The warranty begins from the date of purchase. Marvin has another warranty that runs up to 20 years on insulated glass. This warranty protects the glass against visible obstruction caused by a failure or the air seal of the glass. Visit their website for more details.


Read our warranty documents carefully.
