Reviews
What customers say
Two positive reviewers mention easy operation. One praised the hardware on the vinyl and aluminum range; another said the Ambassador Series aluminum windows were energy efficient, easy to operate and stylish. Critical accounts include one customer's report of repeated order problems and a delay of more than six months, and another customer's report of leaking windows and an unhonored lifetime warranty; a reviewer also said a truck driver blocked a neighborhood street and caused traffic.

Rude truck driver blocked the entire street in the morning, causing traffic in our neighborhood. Totally unacceptable behavior in a residential area.

We used international window company, ambassador series aluminum windows throughout our home and we absolutely love them! Energy efficient, operate with ease, & extremely stylish. Their lifetime warranty is also a big plus!
