We just replaced 19 windows in our home, all of them 6-7 feet tall. After about 6 months of research and price comparisons, we chose Wenco vinyl clad double hung tilt-in windows. The installation was not that bad, and we're exceptionally pleased! A contractor friend also stopped by and inspected our job. He was very impressed and stunned at the price per window... less than what he could normally get through his own channels. He took our info and bid on replacement windows for a 50-unit apartment complex, and got the job.... he is using Wenco.
