We have 4 units on the 2nd floor of C building with contracts with Charles Windows in San Rafael. We did a lot of research and found that this company is the only one that offers a lifetime warranty on installation and windows. We also found that the new window frames are narrower (which we wanted) than the ones now being installed by Arrow and American Windows.

For repair to the side window (cantilever) I used:
640 San Pablo Ave.

For replacement of the big, center window (59 x 70), I went with:

We replaced our solarium windows yesterday with custom double pane windows — and sliders that work! We are on the fourth floor of B Building. You might have seen the installation yesterday morning. Fast. They arrived at 8:30, finished at 11:30.

(Editor's note - this company replaced the windows without using scaffolding. If your condo has a deck which provides access to your windows, you may find other companies who can do the replacement. Once such company is Arrow Glass, 510 525-2118.)
