"Greenwood provided us with a superior customer experience from start to finish. The Greenwood sales rep was the best in terms of explaining the problem and our options in easy to understand language. The installation was quickly scheduled. The installers were courteous and made sure to cover our floors to protect them from any outside dirt and debris. Overall, highly recommended."
