It was time for new windows so we jumped in and got some estimates. Our estimate with Mike was really awesome and informative. Other estimates didn't compare. Just as we expected the windows were custom made for our home and they came out and installed the full house in about 4hrs. They look awesome and we are so pleased!

Seeking a sliding glass door. a rep called and said I had to set up a quote appointment with somebody else to even get pricing. I said, "This is pretty simple, I don't have a ton of time, can you just send me pricing for your options? It shouldn't be this hard to shop." Then Caitlyn said "have a great day" and hung up on me. I don't need multiple appointments to make a decision.
I asked to send options, I want to buy from you, why not make it easy? Also, why hang up on a paying customer? Very rude, not helpful, and they basically through a easy sale out the window.

We have used window world on two different properties. I used to have to cover the windows with blinds and curtains in the afternoon on our west side facing windows because it would emit so much heat but noticed a difference immediately. Installers were on time and professional. Window world stood behind their warranty. We've used window world since 2010 and have never had an issues. We would highly recommend them to anyone looking to replace windows!

Great product, competitive price and fantastic service! I shopped, really shopped for a new sliding patio door. Window World fit the bill. Steve at Window World is knowledgeable and incredibly well versed about his products. Steve is great people-person. He understands the customer and how to explain every step of the process and the payment in terms I can understand, not a bunch of construction industry terms that leave you scratching your head.
I love my new sliding door, I've had it for over 6 months and I couldn't be happier. It's a great product and I couldn't be happier with the staff. I'll use Window World when the time comes to replace more windows and my entry door too. Thank you Window World, I'm very happy.

Worst warranty policy of all time. The seller of the home has 30 days post sale to call in to Window World and transfer the warranty for the buyer. Like that's going to ever happen. What a scam. The seller who bought these windows on my house paid thousands of dollars and that got factored into the purchase price when I bought the home. "But sorry they had 30 days and you don't have a warranty." I definitely won't be using Window World for any of the homes I build going forward.

We were told 12-16 weeks and it's now going on 8 months. The customer service desk isn't helpful and downright rude. Steve Bell, the sales rep, is unresponsive and does not return calls or emails within a week. When he does finally reply he is full of excuses and will do NOTHING to actually help his customers. HORRIBLE experience! This place is not worth the little you save!
When I signed the contract I was told it would take a week from the time they received the windows to install. They do have me scheduled for install in a MONTH! The timeline is frustrating for sure but with COVID it is understandable for everything to take a little long than usually. However, my one star review is due to Window World and their sales rep, Steve Bell's rude and awful customer service.

We had our windows put in last week, and Daniel did an amazing job. He was the most courteous, on time every day, took time to explain any questions I had, cleaned up after himself (there was very little mess) and installed 36 windows all by himself. To say I was very impressed by Daniel is an understatement! Service: Window installation

Avoid this place at all cost! We were told the windows would take 10 to 15 weeks we're now on week 21. This has held up getting our property sold. Accountability? They have none. Very rude and combative. Thank god I only ordered windows and not having them do the install who knows what kind of work would be done and more excuses made. Learn from my mistake do not buy here! Read the rest of the poor reviews as well.

Window World has been excellent to work with. They installed, socially distanced, and the whole process was efficient. I was able to keep working in the background. The glass door is very large and looks amazing. The customer support has been equally amazing. We have had a warranty issue on the screen door and a manager came onsite ASAP to assess and correct.
Excellent value and service. I will be coming back as other doors and windows need replaced. We have had this installed now since May and every has been excellent. Definitely has been helpful to keep heat out and cool air in this summer.
