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.
