Accreditations

Seal-holding products, like Window World’s windows, vinyl siding, and Therma-Tru doors, are evaluated by the Good Housekeeping Institute (GHI) to verify that all product claims are true and that the products perform as promised. GHI also reviews Quality Assurance policies to ensure all products being manufactured are of the same quality as those evaluated in the Good Housekeeping labs. Good Housekeeping stands behind every product that has currently earned the Seal by offering consumers a two-year limited warranty on products and will repair, replace, or refund the cost of the product (up to $2,000) at their discretion; if it proves defective within two years of the purchase date. Certain limitations apply. Reference the GH Consumer Policy here.

If any product that bears our limited warranty Seal proves to be defective within two years from the date it was first sold to a consumer by an authorized retailer, we, Good Housekeeping, will refund the purchase price or $2,000, whichever is less or, at Good Housekeeping's sole discretion, repair or replace the product.

Maintaining our Lead Certification means we are trained and regularly undertake the necessary precautions to protect our customers from the potentially harmful effects of lead. During our installation process, we take special care to ensure we contain any lead dust created, protecting our customers and the environment. Lead, which has been linked to health and environmental issues, is a heavy metal long used in the manufacturing of paint, plumbing pipes and leaded gasoline, and can still be found in many homes built prior to 1978. By following lead-safe work practices, we mitigate the risk of lead exposure associated with disturbing remnants of lead-based paint/products.

The Better Business Bureau is the leader in advancing marketplace trust, focusing on integrity and performance. Its work is giving consumers and businesses an unbiased source to guide them on matters of trust, providing educational information and expert advice. Our BBB accreditation is an honor, indicating we met its strict standards for conduct and product performance.

The ENERGY STAR® program is a joint venture of the EPA and the U.S. Department of Energy. Its goal is to help consumers save money and protect the environment by identifying energy-efficient goods and practices. Products that earn the ENERGY STAR prevent greenhouse gas emissions by meeting strict guidelines set by the U.S. Environmental Protection Agency and the U.S. Department of Energy. Window World offers a variety of window and door packages that are ENERGY STAR qualified in each of the nation's four climate zones.

The National Fenestration Rating Council establishes test criteria that set the standard for performance ratings of window and door products. These consistent ratings provide accurate information on the energy performance of windows, doors and skylights. The presence of these ratings allows products across the industry to be compared on an unbiased basis.

ASTM International, formerly the American Society for Testing and Materials, is the globally recognized leader in the development and delivery of voluntary consensus standards. Its mission is to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. Our windows have been tested and are confirmed to meet the air, water and structural integrity standards as defined by ASTM.
