I purchased 13 windows for my home from Window Nation. The people I dealt with were, friendly, knowledgeable, and really went out of their way to help me find a window that met my HOA requirements. The windows I selected are eligible for the 30% energy tax rebate from Uncle Sam. Installation was quick, and the installers were promt, prepared, and very respectful. I would definitely tell anyone looking for windows to give these folks a call. They also have some very affordable financing options, be sure to ask.
