Other considerations and costs

  • The window installation influences curb appeal directly and flaws are glaring ones.
  • Typical upgrades and accessories are reviewed in the related Cost Guide.
  • These prices are for service in the immediate area of the provider.
  • Taxes and permit fees are not included.

  • During contractor inspection the homeowner should be informed of any repair concerns like rot, and the cost to adapt the existing window-opening structure.
  • A project to replace more than 2 windows should enjoy a unit price discount.
  • There may be local or national subsidy for energy efficiency improvements.
