2Should I replace the original windows in my Greenwich home?

Energy-efficient windows also qualify for federal tax credits up to $600/year.
3How long does window replacement take in Greenwich?

4What window styles fit Greenwich's Colonial homes?
Colonial homes in Greenwich typically look best with double-hung windows that match the original proportions. For Colonials, grid patterns (6-over-6 or 6-over-1) maintain architectural character while upgrading to modern energy efficiency. Casement windows work well for additions or sunrooms. Budget $800-$1,500 per window installed for quality brands like Andersen or Marvin.
