A++ I used Bel-Air Exteriors and I am very glad I did. My salesman Larry I feel is honest and professional. Their work was clean, and the windows are Fantastic! My house became so quite, I don't hear the leaf blowers or kids on Saturday. My friends comment on how nice they look. Bel-Air did some technique where they pulled the old frames out without damaging my stucco. The result was a larger window that fit better into the opening. I paid more for them, I took a real leap of faith because they were 10% higher then other bids. I am so glad I used professionals that did it right the first time... I had the job done in 2005 and they are still perfect now in 2009. My "know-it-all Brother in law used a mass marketed company, and he's still arguing with them over some retrofit trim not sealing water leaks properly. A++ Highest recommendation for Bel-Air Exteriors!!
