Hey South Jersey -
I would search this BB and their sister Board (www.replacement-windows.com
I signed up for angies list, but didn't have to pay. They're one resource to check out installers. I'd also check your better business bureau, and your county consumer affairs department as well.
I know you're supposed to check for references, but from my 3 contractor experiences (and lots of contractor shopping) - the contractors only give you good references, and they may not be for the exact project you want.
Also, HD doesn't have a good reputation as the sub out all the installation. Do your homework on the type and quality of windows you're getting - www.nfrc.org
is a good place to start there.
