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 St. Petersburg median.

ScopeWhat it includesTypical installed cost
5 windows — retrofitInsert into sound existing frames, vinyl$5,800$8,400
10 windows — retrofitTypical partial-home replacement$11,700$15,900
15 windows — mixedMost of a single-family home$16,700$22,500
20 windows — full-frameWhole-home, frames and trim replaced$22,500$30,900
10 windows — impact / structuralImpact-rated or egress-corrected openings$19,200$26,700
  • 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 St. Petersburg median for window replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology

Frequently asked questions

Do I need a permit to replace windows in Florida?

Yes. Window replacement is a permitted alteration statewide because the opening protection and attachment must meet the wind-load requirements of the Florida Building Code. Product approval numbers are submitted with the application.

Are impact windows worth it in Florida?

Impact windows typically cost 40-70% more than standard units but can replace shutters entirely and often qualify for a wind mitigation insurance credit. In HVHZ counties, opening protection is required, so the practical choice is impact glass or approved shutters.

Do I need a permit for window replacement in St. Petersburg, FL?

In most jurisdictions this work is permitted and inspected. Requirements are set locally, so confirm the current application and inspection checklist with your building department before work starts.

How long does window replacement take?

1-3 days of installation, 3-8 weeks including product lead time and permitting. Permit review and inspection scheduling are usually the largest source of variation.

What changes the price the most?

The largest cost drivers are number and size of openings; impact-rated versus standard glass; frame material: vinyl, aluminum or fiberglass.
