The excellent service we received from technicians Albert and Brandon have far exceeded our expectations. Both guys (on separate occasions) have gone above and beyond all while having a smile on their face and provided excellent customer service. They are hard working guys that display professionalism and knowledge of the work they are doing, friendly and courteous. Albert had switched out the weather stripping on all our windows and Brandon made and replaced our screens. Albert and Brandon, Gilwin is very lucky to have you on their team and please know my family greatly appreciates both of you. Thank you kindly.

My experience with this company had always been excellent. It's quality is comparable to your other big box/brick and mortar brands but what sends me back (my third visit will be on Monday) is the price and while home depot or lowes will say their shipments will be 2 to 3 months for delivery (and I'm sure it'll take longer) I could depend on these windows less than 2 to three weeks. I'll be going back this Monday for 2 other windows that both home depot and lowes is not stocking grid inlaid. I'll be sure to leave another review on how soon it's completed for pick.

If I could post a NEGATIVE star, they would get that. We called and left multiple messages for this company, was told that the driver FORGOT to put our door on the truck, instead of following up on my door which shattered for no reason I had to call them. They took messages and never returned my calls. They kept saying that the manager won't be in until later and that the plant manager is out of the office. That we don't have to date for you yet. What kind of company waits 10 days to decide when they will get back to you? If you're a builder or home owner, go with someone else. There is NO CUSTOMER SERVICE with this company. It's been a horrible experience and we decided to go with a completely different window company which was charging us more. I'll pray that they will eventually get better Good luck to those of you who are trying to get hold Gilwin Windows.
