We need to replace our patio doors and would like to replace windows throughout our house. It is a 1400 sq. ft. rambler so only has 9 windows total. We'd like to do this cost-effectively because we plan to sell our home in 1-3 years. There are lots of sale and 0% financing offers in the Post lately - Renewal by Anderson, Pella, Thompson Creek. Any suggestions of the best company to go with and ball park ideas about how much this will cost?
