National Baseline & Scope Drivers

Replacing residential windows, either as inserts into existing frames or full-frame replacement. National planning range for this job sits between $450 and $2,500.

Key Price Drivers for Window Replacement

  • Insert versus full-frame: An insert fits inside the existing frame and is cheaper and faster. Full-frame replacement removes everything to the rough opening and is required when the frame or sill is rotted.
  • Frame material: Vinyl is least expensive, fiberglass and composite sit in the middle, and wood-clad is the most expensive. Aluminum performs poorly thermally in cold climates.
  • Glazing package: Double-pane low-E is standard. Triple-pane, laminated and impact-rated glass each add meaningfully, and impact rating is mandatory in many coastal zones.
  • Size and operation: Casement and awning windows cost more than double-hung. Large picture windows and anything requiring two installers cost more to set.
  • Condition behind the trim: Rot at the sill and rough opening is common in older homes and is only discovered once the old window is out.
