Warranty review is important to understanding how the window or door is made and the quality of the components and manufacturing process. Also, the warranty may illustrate how long the manufacturer has been in business, where the factories are located, and how they handle warranty service. Due to the performance of windows and doors in the building envelop, we encourage research and awareness of manufacturers from overseas with no service departments for our forever home clients. Buying direct from a manufacturer that does not invest in a dealer or post-sale warranty service support may seem advantageous from a cost standpoint, but looks different from a long term investment value should there be warranty service needs of replacement parts down the road.
