Anderson, Pella, Harvey, Marvin windows?
Anyone have an opinion of which company makes the best window? We just installed 4 Harvey double-hung windows and are quite pleased with them. But friends also installed 4 new Andersons that look just as good, same price--$400 each (30'' x 52''). If we replace all our windows we are looking at over 30 windows, so it will takes us 3 to 5 years.
