We got new windows with a contractor, Jim,
Who installed them. We were very happy, until the middle of the winter, 2019, when I noticed the large picture window got a tiny crack in it. I informed my husband that he needed to get that taken care of the next day. Jim was out of town until spring. In the meantime, the crack is spreading across the window, and is causing a draft. And I am concerned.
My husband called again. This time, Jim is having a hard time with his wife on hospice. So again, we wait. Why is no one calling back? It is now almost August and the window is falling apart! Do not ever

We decided to get a quote from Crystal Window & Doors after a co-worker referred them. When I contacted them, they asked for the home address and my phone number as they were going to have their salesmen give me a call to book an appointment. After about a week of not receiving a callback, I called them again. The lady who answered the phone was surprised that "Brad" had not called back. She proceeded to text me his number so that I can call him directly. When I called him, he said he was getting ready to call me and arranged an appointment for a Tuesday. On Tuesday, he called

This company deserves 0 stars. My husband and I didnt get a chance to order the windows with them because I was turned off immediately by there service. What happen was I went to the store to obtain a quote and that went smooth with Cristian. Eventually there contractor Brad came out to measure all our windows and told us at our appt that he would get back to us with the price. Our appt was very quick and when I mentioned I wanted my bow window to be "deeper" he said it absolutely could NOT be done because the size of our wall. Well dont be fooled, always get a second opinion because

I placed an order for several windows for one of my buildings but they weren't able to deliver on time. When I called customer service to cancel, they gave me the run around. Had to contact my credit card company to get my deposit back. Was able to get my windows put in faster and cheaper by buying them at a big box store and hiring an independent installer.

This place is not worth the discounted prices. Windows are poorly constructed. Very unprofessional and disorganized. I've had to make 2 more trips simply because windows were either not ready, forgot to mold together or molded incorrectly. I was told my windows would be ready in 3 to 4 weeks. They were ready in 5 -1/2. I will never do business with this company again
