Window Replacement Cost: What to Quote Per Window

Window replacement costs $450 to $1,200 per window installed for most homeowners in 2026, with a full-home average around $500–$1,050 per window depending on frame material, glass package, and size. Premium windows — larger sizes, custom shapes, or high-end frame materials — can run $1,200 to $2,800+ per window.

Window cost by frame material

• Vinyl: $450–$900 per window installed — the most common replacement choice for cost and low maintenance.
• Fiberglass: $700–$1,400 per window — more durable and better insulating than vinyl, at a real price premium.
• Aluminum: $500–$1,000 per window — common in warmer climates and modern architectural styles.
• Wood: $800–$2,000+ per window — the highest material cost, chosen for appearance and historic-home matching.

What moves the price per window

Installation type

Insert (pocket) replacement — installing a new window into the existing frame — is faster and cheaper than a full-frame replacement, which removes the old frame down to the studs. Full-frame installs cost more but are necessary when the existing frame is damaged or significantly out of square.

Size and glass package

Larger windows and upgraded glass — double vs. triple pane, low-E coatings, argon fill — add real cost per unit, and it's easy to underquote a job with several oversized windows if pricing is based on a single "average" window rate.

Number of windows and access

Whole-house replacements typically get a per-window discount over single-window jobs, since setup and crew mobilization cost is spread across more units. Second-story and hard-to-access windows add labor.

Quoting window jobs faster from photos

Window counts and styles are easy to verify from photos — each elevation of the house, or even a walk-through video, is usually enough to count windows, identify approximate sizes, and note any frame damage before a measuring visit. Fast Snap Pro lets a homeowner send those photos through a link and get back an AI-scoped estimate priced against your own window installation rates, so a multi-window lead gets a real total price back fast instead of waiting days for a scheduled measure.

Frequently asked questions

How much does it cost to replace all the windows in a house?

For a typical home with 10–20 windows, total replacement cost usually runs $5,000 to $20,000+, depending on frame material and window size.

What's the difference between insert and full-frame window replacement?

Insert replacement fits a new window into the existing frame and is faster and cheaper; full-frame replacement removes the frame down to the studs and costs more, but is necessary when the existing frame is damaged.

Is vinyl or fiberglass better for replacement windows?

Vinyl is more affordable and low-maintenance; fiberglass costs more but offers better insulation and durability over time. The right choice depends on budget and how long the homeowner plans to stay in the home.

Do window replacement quotes usually include a per-window discount for larger jobs?

Yes — most contractors price whole-house window jobs at a lower per-unit rate than single-window replacements, since crew setup cost is spread across more windows.
