On time and professional service. Windows have never looked so good. Highly recommend.

Sam and Nate did an amazing job on our windows. They’ve not looked this good since the day they were installed. I’ve had other companies come out and ended up with streaks and dirt on my windows. They showed up in time and were very friendly. Highly recommend The Cool Window Guys.

"I had an amazing experience with The Cool Window Guys in Greenville, SC. From start to finish, everything was professional and easy. My windows had a lot of built-up dirt and water spots that I honestly didn’t notice anymore until they showed me the before and after results. The difference was night and day. The glass was crystal clear, the frames looked brand new, and the whole house felt brighter inside. They even walked me through what they were doing and showed me the improvement as they went, which really highlighted how much buildup there had been. If you’re looking for reliable, high-quality window cleaning in Greenville, I highly recommend The Cool Window Guys. Great communication, great results, and clear pride in their work. I’ll definitely be using them again."
