I am planning to change the aluminum frame windows on my 25 year old house and had so far been considering the so called 'replacement windows'. I had several quotes ranging from $6K to $18K (home depot Jeld-Wen to Renewal by Andersen) and was in the middle of my decision process until some roofing contractor told me that most replacement windows installed on stucco start to leak after a few years. He advised me to look for 'new construction windows'. He said from personal experience, whenever calls came in to repair roof leaks, the leaks were invariably due to the faulty caulking around replacement windows.
Any advice? Thanks.
