Florissant, Missouri Customer Reviews

  • This is the third time we have used Window World for replacement windows in our home. The installers provided by WW have always been very good. They work quickly and efficiently doing their best to avoid issues for the homeowner. We will be contacting WW again next year to replace more windows. They have earned our business.

  • Jeremy was courteous, professional, covered ( and cleaned up) the work area and left me with some beautiful windows. When I chose to use Window World, there was NO pressure to purchase, I was given 3 different estimates and decided to use them, without getting other bids. I was confident that I was a getting a good deal and would definitely recommend this company.
