I'm going to be replacing some windows in my house, and recently obtained 2 quotes from the Big Two DIY mega stores. Lowe's quoted me about $1000 for the configuration I want, using Pella's 25 series. For the same configuration and features, Home Depot quoted me $600 for the Jeld-Wen Sierra Side Load series. What gives? Assuming proper installation, is there a quality difference that would account for the pricing? I live in Seattle, and while it can get 'chilly' here our winters are not extreme by any stretch.
Any help would be appreciated.
