Originally we had 2 windows that needed replaced. The appraiser, from Window World, was very informative and knowledgeable. Throughout the appraisal he was content with replacing the bad windows. We discussed our options and chose replacing 5 windows of the same size. When the call came to install the windows 2 very considerate installers arrived around 1:00pm. They started the job all the while they kept us informed of progress. 5 hours later, all 5 windows were installed. They totally cleaned up after themselves. The job was so professionally accomplished, you can't tell the difference from the old or new windows. Lifetime guarantee, including screen replacement, fantastic. We are 100% satisfied with the whole process from appraiser to finish installers process. We will definitely recommend Window World to anyone needing customized replacement windows.

Customer Reviews

  • "I hired Window World for an install of three extremely large slider windows. These are windows other companies said could not be done. The windows were installed over the course of a day and a half, and the installers exceeded my expectations in every way, as did the quality of the windows! I highly recommend them to anyone!"
