  • Greenville Window & Door completed installing our bay window and a french door today, amazing job. We love the factory painted finish on the door. It looks amazing & it operates so smoothly. Allen & his crew were so courteous. I wish they would have offered to paint the interior of the bay window. I was told i would have to paint it, but just a thought for the future.

  • I wish google allowed me a one-time review with 6 stars! (Or more) With unbeatable prices for such high quality, there really isn’t any other company I would consider. Robert with Greenville Window and Door is honest, attentive, customer friendly, and everything in between. Dimetry was our installer, and if you ever have a choice, choose him! He was very detail oriented, so incredibly friendly, and really made sure the job was done perfectly. Also, from initial consultation, our job was done in a ridiculously short amount of time. I would recommend them to anyone and everyone I know!!

  • I am not one to leave reviews, but we were so impressed we had to. You can trust that Greenville Window will do what they say they will. We were so pleased with our sales representative Greg, the crew followed through with everything he said they would. The guys did a great job, very professional from beginning to end, they even washed the glass for us before they left. I will be recommending this company to everyone we know.

  • I am excited that I got my new windows installed today. The team at Greenville Window & Door are great to work with. Robert did a great job expaining why their installation style was so different from the rest. Wow was he right, my neighbors windows were wrapped with aluminum on the exterior by another company and compared to my beautiful composite trim, my home looks so much better. I will be referring your company to everyone I know.

  • I purchased 12 windows and 3 doors from Colton and they were installed today and Allen and his crew did an amazing job. The guys were very respectful of your home and showed how to use the windows before they left. They cleaned up after themselves all 3 days they were here. I was also very impressed when our sales rep stopped by to check on the crew and he gave us a gift certificate Carrabba's. Thanks Colton you have been a pleasure to deal with. Greenville Window & Door was the right decision for us.
