The Alside windows marketed by Apex Energy Solutions are a far superior product compared to ""big box store"" offerings and several other replacement windows that I researched. We replaced our original Pella wood windows which were rotting after 15 years. We are very pleased with the quality of the windows and the quality of the installation. This is the second set of windows purchased through Apex. We replaced south facing windows in 2008 and north facing windows this year.
Pros: High quality and very nice installation
Cons: hard to reach marketing rep on occasion
