What window replacement costs

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 prices those components separately, the methods hub explains what each install type actually does, and the problems hub 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.
