We are replacing all 18 steel casement windows on our 1947 brick and block house. Looking to replace with mostly double hung (some casements, depending on configuration). Had a visit by Renewal by Anderson today, Pella and Thompson Creek (local to the DC area) are lined up for next week. From what I've read here so far, I should also check out Marvin. I know quality installation is at as important as the window manufacturer, and I will tackle that next. For now, I'm trying to determine what brands and what specific lines I should be looking at. We have waited 17 years to tackle this project, and we want to do it right. Looking for high quality/performance.

Recommendations? Thanks!
