It's time to replace all the windows in my house, including a 144" bow. Want
to get good quality windows (double pane with gas inserted), probably vinyl,
but there are so many window companies, each one saying that their product
is better than all the others. Any suggestions on how to make the right
choice. Thanks.

A high percentage of windows these days are fine quality. Andersen,
Pella, Jeld-Wenn, Crestline, and many others are well made. Like every
industry there are the fringe players, typically installers with a
connection to a small poorly run manuacturer. The tip off there is the
high pressure sales tactics and huge 'discounts if you sign today' and
pay substantial money up front.
The usual techiques for screening contractors apply...check out the
archives of this NG for tips. Contractors working for the box stores
have a less than stellar reputation, so an independant firm may be
best. Window installation is not all that hard to do, but a careless
installer can muck up a fine product quite easily.Good luck.
