Cost by window count and install type

Windows are priced per opening. Frame material and whether the crew does a retrofit (insert) or full-frame install drive the spread. Every row is priced against the Casper median.

ScopeWhat it includesTypical installed cost
5 windows — retrofitInsert into sound existing frames, vinyl$5,000$7,200
10 windows — retrofitTypical partial-home replacement$10,000$13,600
15 windows — mixedMost of a single-family home$14,300$19,300
20 windows — full-frameWhole-home, frames and trim replaced$19,300$26,500
10 windows — impact / structuralImpact-rated or egress-corrected openings$16,400$22,900
  • Retrofit inserts keep the existing frame and cost less; full-frame replacement is required once the frame or sill is rotted or the opening is being resized.
  • Rough-opening changes and egress corrections turn a window job into a permitted structural job.
  • Frame material sets the floor: vinyl is the value option, fiberglass and clad-wood carry a premium, aluminum is mostly a warm-climate product.
  • In wind-borne debris regions the glazing package, not the frame, is the biggest single line item.

Basis: Each scope is priced as a multiple of the modeled Casper median for window replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology

$5,700

40% of the median — the rest is material, disposal and permit.
