We did our windows a couple years ago. I used a local outfit in San Leandro (Manor Glass) and Mike came out and it was basically 500 bucks a window installed. Replacement windows for the aluminum single panes put in the house in 1983 when they did the gutting and addition. The guy actually remembered being a teenager and installing them with his dad - LOL what are the chances... Local town. Anyway we bought Mercer Windows (who have been sold) but the warranty and quality, unless you have to have a brand name - is perfectly fine. 14 windows, 7 grand - done. And a few were huge fronts. So my point is look to the local guys - this is a great time of year to look for windows - when things are slow-ish and have not picked up. There are plenty of perfectly fine window makers and will you go through three sets of 500 a pop windows before you go through a single set of 1500 a pop windows with a neat sticker? Probably not. Local guys - check them out - the ones that have been around for a while and are on second generation. By the third generation they are idiots, so it seems of any business.
