"Charles and Shae did a great job at our remodel. They were very professional and polite and personable with our family while they were here. The shower remodel looks great and work was outstanding. Would highly recommend these 2 for future installment projects."

"I'd like to start by saying that being a first time homeowner knowing you have to do home improvements is kind of a scary thing. It's not like going to the store to purchase a pair of jeans and if you don't like the way they fit, you can return them. We reached out to AJ Windows and they made the uncertainty and fear disappear. What a pleasure it was to do business with this crew! Nothing less than professional and kindness from the beginning. The presentation of the products offered and how energy efficient the products were going to be once installed in our home was beyond impressive. AJ Windows offered us financing that fit our budget. The windows were custom made in which were completed earlier than the time frame stated. We were excited to have them proceed with the renovation to our home and when the crew arrived the installation started immediately. The crew was knowledgeable, kind and respectful. Hard working doesn't even begin to describe them! We had every window in the house replaced. Our home is absolutely beautiful! We are very happy with them and we are truly grateful to AJ Windows for the kindness they have showed us. Nothing less than a FIVE STAR service from the very beginning. I would strongly recommend AJ Windows for your future renovations of window and door needs. Thank you Eve and crew for making this a worry free experience ... we just can't say enough about you all ... *****+ service."
