We are building a year-round house in NH. We need mostly double-hung vinyl, J-channel. The two companies that have been offered are Jeld-Wen, Premium Vinyl w/brickmold casing OR Mathews Brothers either Walcott or Sanford Hills lines. Is it worth the extra $$ for MB? Or should we be looking at a different line of windows? We don't want to go overboard, but are willing to pay for quality. Our builder has worked with both these companies.
