I have been dealing with San Gabriel Sash for many years. Tammy is the absolute fastest and most responsive at getting prices back to you and has a vast knowledge of the products she sells. In the replacement window business there are a million horror stories about windows that 'came in wrong' or didn't fit. S G Sash takes the time to verify every measurement and so far in 18 odd years I have never had a window that didn't fit right the first time. They are in the shop on Saturdays as well.
