Why Strong Window Warranties Are Important

While there are several factors to be considered when buying replacement windows, warranty is a factor that shouldn’t be overlooked. Not all replacement window warranties are the same, and choosing the right one can save you from unplanned repair or replacement expenses. The paperwork may be worded differently, but the important elements should be recognizable.

What Strong Replacement Window Warranties Should Have

Replacement window warranties – and most warranty coverage in the remodeling and building industries, for that matter – should always have material and workmanship coverage. Material warranty is alternatively referred to as factory or manufacturer’s warranty, and covers problems that may be caused by material or manufacturing defects. In terms of replacement windows, material warranty could apply to the entire replacement window assembly, or to the frames, glass and hardware individually.

Workmanship warranty, on the other hand, covers problems that may arise from improper installation processes. Not all window contractors and manufacturers offer this, yet it’s the most critical part of the warranty coverage as a whole. After all, even the best replacement windows won’t work as expected if they’re not properly installed.

"I would recommend RBA of Central Illinois for QUALITY windows and doors. Compared to our old cheap, thin vinyl windows, Andersen blows them away. You can easily tell by how well the sliding doors fit and close, and how heavy duty they are. We also cannot hear the wind rushing through the house in inclement weather anymore! And the black window frames we went with are amazing to look at. Aaron, Al, Darrell, and Cory all were professional and went all out to finish the job, given the weather they had to deal with. I would definitely recommend. They were also on top of communicating with me given the weather delays, and what I could expect for them coming out. Five stars!"
