“I’ve been happy with “window world”.”
“We did Window World in Manchester a few years ago. Happy with the service and the price.”
Allison addressed my issue so professionally and quickly facilitated my replacement windows. The gentlemen who did the installation were polite, efficient and took such care in their work.
Made a call yesterday had a visit today. The next day and the window issue was solved within 15 minutes. Allison and her crew are great, they will accommodate anything that needs to be done with no debating. If you need windows, forget the other companies. Like Anderson's and all the other big names and go with Window world. Their customer service is super great. And the lifetime warranty is exceptional. If I had another house and needed windows, window world would be the only company that I would choose. Some people are scared to go with W.W, Because they're not a huge forced upon the community named company like Anderson's and the other big name companies. But believe me for the quality and the service that you will get from them, Is exceptionalany forget the big name companies or higher price windows. believe me, you are getting a super superior. quality window just as good as Anderson's and the other ones out there. I mentioned Anderson's, because they are the only company that are constantly pushing their name out to the community to get their windows sold. Window world is a family owned business and a great. Addition to and for the community.
Both workers did a great job! They worked from 9-5 nonstop! Carlos was very knowledgeable and made it look easy! I have already received many compliments! I will definitely be using Window World again !
