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 Flagstaff median.

ScopeWhat it includesTypical installed cost
5 windows — retrofitInsert into sound existing frames, vinyl$6,700$9,600
10 windows — retrofitTypical partial-home replacement$13,400$18,200
15 windows — mixedMost of a single-family home$19,200$25,900
20 windows — full-frameWhole-home, frames and trim replaced$25,900$35,500
10 windows — impact / structuralImpact-rated or egress-corrected openings$22,100$30,700
  • 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 Flagstaff median for impact window installation, so the scenarios, the size table and the calculator always agree. · Hometriva methodology

Labor in the price

$7,300

38% of the median — the rest is material, disposal and permit.

Frequently asked questions

Do impact windows need a permit in Florida?

Yes. Replacing a window changes an opening protection assembly, so every Florida jurisdiction requires a permit with product approval numbers and attachment details for each unit.

Do impact windows lower insurance?

Florida requires insurers to offer wind mitigation discounts for approved opening protection. Have a wind mitigation inspection done after installation so the credit is applied.
