It depends on budget, style preference, and region, but here’s a useful overview:
For vinyl windows, Andersen and Pella are widely regarded as top national brands, known for durability and energy efficiency, though pricier. Milgard is well regarded on the West Coast. For wood windows, Marvin and Andersen’s wood lines are popular for custom builds. Budget-conscious buyers often choose Simonton or Ply Gem.
Your best move: get quotes from 3 local installers, check warranties, and look up reviews specific to your region, since installation quality often matters more than brand name.
