Frequently asked questions
How much does window replacement cost per window?
Most U.S. homeowners pay about $650 to $1,900 per window installed, depending on size, frame material and glass. A typical whole-house project of 10 to 20 windows lands around $7,500 to $34,000.
Is it cheaper to replace all windows at once?
Usually, yes. Contractors spread setup, travel and crew time across more openings, and manufacturers often discount larger orders. Doing it in phases works, but expect a higher per-window price.
Vinyl vs. fiberglass windows: which is better?
Vinyl is the most common and lowest-cost frame. Fiberglass costs more but expands less with temperature changes, holds paint and suits dark colors and large openings. Both outlast older aluminum frames in most climates.
Do replacement windows need a permit?
Many U.S. jurisdictions require a permit when the opening size, egress or structure changes, and some require one for any replacement. In high-wind coastal areas, product approvals and design-pressure ratings are part of the review.
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.
