Home Depot does not manufacture windows itself. Instead, it partners with third party installers through its Home Services program, offering free in-home consultation and measurement.
Installation labor typically runs $150 to $400 per window, but total project cost, including the window unit, usually lands between $300 and $1,500 per window depending on size, material, and style. A whole home job covering ten to fifteen windows commonly totals $4,000 to $15,000 or more.
Pricing is only finalized after an in-home measurement, so advertised figures are starting points. Financing options, including promotional no interest periods, are often available for larger projects.
