Excellent quality installation of our front door. The entire team was meticulous and took their time and great pride to ensure an exact flush, square, and perfect threshold height. This was a custom door needing to squeeze into existing brickwork and low outdoor ceiling. I highly recommend JC Windows to do any window / door install! Great work from a professional and honest company!

An absolutely amazing experience! We had wood windows that were over 100 years old. With winter quickly approaching we got a recommendation to call Oscar and its hands down the best decision we have made as new homeowners. He's reliable, reasonable and informative! 5/5 stars isn't enough to capture how happy I am with the result.

Amazing experience! Honestly one of the best experiences we have had with a contractor. Extremely professional and organized; these guys really know what they are doing and will get the job done right. We had 15 windows changed in our house. They explained the process, measured the windows and the installation was seamless. I highly recommend you give them a call for all your window and door needs. You won't regret it! Oscar and his team are the best!
