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.
  • If the installation requires a new opening of a wood-framed exterior wall, that work will cost from about $900 to $1,200 per window unit of 4’ x 4’ (or $56 to $75 per square foot generally), depending mostly upon local labor rate.
  • 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.

DIY considerations

  • This project may not be suitable to an able and prepared DIY person with typical contractor’s tools.
  • Skillful carpentry is required, and a critical closure deadline is common.
