For the eighth consecutive year, Window World’s windows have earned the Good Housekeeping Seal.

“Window World is dedicated to providing world-class, American-made windows and doors, installed with careful attention to detail,” said Mark Bumgarner, vice president of operations for Window World, in a statement. “We are proud to be one of only three companies in the home improvement industry that currently sells windows that have earned the Good Housekeeping Seal.”

Champion and Earthwise are the other window manufacturers that have been recognized by Good Housekeeping.

The Good Housekeeping Institute (GHI) evaluates safety, performance, ease of use, durability and design.  Good Housekeeping offers a two-year limited warranty on seal-bearing products, replacing, repairing or providing a refund up to $2,000 for any merchandise found to be defective. This warranty complements Window World’s own lifetime limited warranty.
