## The installed price table

A window price is not one number. It is a unit, the labour to set it, the removal of the old one, and the weatherproofing and trim around the opening. Any quote that shows only a total has hidden three of those four lines.

 |  | Job | Typical installed range | What it includes

 | Single vinyl double-hung, insert | $350–$800 | Unit, insert labour, removal, basic seal

 | Full-frame replacement | $550–$1,100 | Old frame out, new flashing and trim

 | Fiberglass window, installed | $600–$1,200 | Better thermal edge, higher unit cost

 | Wood or wood-clad, installed | $900–$1,800 | Solid or clad frame, paint or stain finish

 | Bay or bow window | $1,500–$5,000 | Multi-panel unit, structural opening

 | Impact (hurricane) window | $1,200–$2,600 | Laminated glass, impact-rated frame

 | Glass pane or IGU only | $150–$450 | New glass into the existing sash

 | Window screen replacement | $100–$350 | Frame and mesh, standard size

These are planning bands for the United States, checked in November 2026. They describe the *window plus independent installer* market. A full-service replacement company prices the same opening at roughly twice that, because it carries its own crews, a longer labour warranty and a sales cost per job. Both numbers are real; they are not the same product.

## What moves the price

- **Install method.** Insert keeps the existing frame. Full-frame removes it and rebuilds the opening — roughly double the labour, plus trim.

- **Size.** Glass and frame are priced by area, so an oversized unit runs about 1.7× a standard one before any upgrade.

- **Frame material.** Vinyl is the value baseline. Fiberglass runs about 1.6× and wood-clad about 2.4×.

- **Glass package.** Double-pane Low-E with argon adds roughly 12% to the unit and is usually the better buy than triple at 30%.

- **Access and condition.** Second-storey openings, finished interiors, and any rot found after removal all add labour.

- **Permits.** $0–$350 depending on the jurisdiction and whether the opening changes size.

## What a quote should show

Ask for the same five lines from every installer: unit brand and model with a U-factor, labour per opening, removal and disposal, flashing and weatherproofing detail, and the trim allowance. A quote that shows a total and a discount is a price, not a scope.

The [calculator](/calculator/) prices those components separately, the [methods hub](/methods/) explains what each install type actually does, and the [problems hub](/problems/) starts with the diagnosis every quote should follow.

### Why do published window costs disagree so much?

Because they price different markets. Ranges from $350 to $1,600 per window are all correct once you know whether the number describes a unit plus a local installer or a full-service contract.

### Is the cheapest quote a red flag?

Usually it is a scope difference — no permit, no trim, thinner glass, or disposal left to you. Compare the five lines, not the total.

### How long is a window quote valid?

30 days is common. Glass and vinyl prices move with resin and freight, so ask what happens if you sign after the expiry.
