Window World Review

Sarah Badani

In a Nutshell

Window World was established in 1995 and is the largest company for replacement windows in the US, sourcing all of its materials from within the USA with a large range to choose from. The service that Window World offers is backed by a nationally recognized company, but as the company is a franchise, it means that it’s able to give attention to detail and the personal touch for all of its clients that other large companies are not able to do.


  • Quality products
  • Nationally known and locally owned

Window World is known for offering competitive prices, but it is very difficult to be able to give an example of the cost of replacing windows, as they vary so much from home to home and products used, as well as the different complexities that may be involved. Because of all that, the price will not be known until the day of your consultation. Also, you should bear in mind that as the company is franchised all over the country, the price may also vary depending on the franchise owner and the market in your area.


Satisfied clients of Window World had the following to say:

  • ‘We appreciate the lack of “hard sell” techniques that caused us to turn down other companies before you’ M. Richardson, Window World of Harford County

  • ‘We had 16 windows installed and they were done great. The crew that installed them was very good, and had all 16 windows installed in one day’ B. Detschel, Window World of Ocala

  • The team was ready to begin promptly at 8am. Polite, courteous, hard working, and most important, did a very professional job’ S. Jaworski, Window World of Altoona

Customer Service and Response Times

When you contact Window World, you need to contact the franchise in your area, which can be found on their main website. Your local franchise will send out a rep to come and give you a consultation. And if you then need to apply for financing, this can be done online during your consultation. Once you have chosen your products and been approved by financing, the wait to receive your windows and for installation is approximately 6 weeks.

Customer service can be contacted throughout this process and after, either by phone or by filling out the online form on the website. Response times vary depending on location and the reason for the query. Window World’s customer service can be contacted 24 hours a day and 7 days a week online, but to speak to a customer service representative, you need to check the hours of your specific franchise. The corporate office phone number is 1-866-740-2100.


Window World has what is known as a limited lifetime warranty on all of the products that they install. This means that as long as the original purchaser of the products from the company lives in the home, they remain insured. If a new homeowner purchases the property, they can purchase the warranty by paying a fee for the transfer, as long as they do so within 30 days of purchasing the home.

The following is covered under the warranty:

  • Glass breakage

  • Vinyl parts

  • Insulated glass

  • Mechanical parts (locks, vents, etc.)

  • Labor
