Current benchmarks

Average window replacement costs

Use more than one data point. A national average is useful for orientation, while your final quote depends on the exact window, glass, opening and installer scope.

Understand the quote

Most of the benchmark is the window itself

Modernize's national dataset separates its $1,047 average into roughly $897 of materials and $149 of labor. Treat those figures as a dataset breakdown—not a rule for every contractor.

Materials

$897

Window unit and associated material component in the source dataset.

Labor

$149

Average labor component reported by the same dataset.

Interactive comparison

Compare frame materials before you price brands

Material choice changes budget, maintenance and design. The figures below use the same current installed-cost dataset for a cleaner comparison.

2026 installed benchmark

$450$850 / window

Maintenance: Low

Strengths

  • Lower upfront cost
  • Low routine maintenance
  • Widely available

Tradeoffs

  • Fewer premium customization options than wood
  • Performance varies by product line and climate

Longevity note: Longevity varies by product, climate, installation and exposure; verify the specific warranty. Also verify NFRC ratings and the local installed quote before buying.

Window styles

Style can change the budget as much as material

Projected bay and bow assemblies occupy a very different price band from common double-hung or sliding replacements.

Double-hung

$500$1,400

Two vertically moving sashes; common in traditional U.S. homes.

Brand research

Compare the series—not just the logo

Manufacturer portfolios differ by product line. Use official material information, certified performance and local installed quotes before deciding.

Andersen

Andersen spans value-to-premium replacement options and uses different material systems by product line rather than one universal frame construction.

Notable lines

100 Series400 SeriesE-Series

Pella

Pella's current replacement catalog includes wood, fiberglass and vinyl options across multiple style and feature tiers.

Notable lines

Marvin

Marvin focuses heavily on fiberglass and wood-based premium systems, with different interior/exterior material combinations by collection.

ENERGY STAR + NFRC

Use certified ratings, not vague “energy-efficient” claims

ENERGY STAR says certified windows are independently tested and verified through NFRC procedures. Its guidance also reports average energy-bill savings of up to 13% in the stated single-pane replacement comparison.

U-Factor

Heat transfer

Lower generally means better insulation

SHGC

Solar heat gain

Preferred level depends on climate and orientation

VT

Visible light

Higher means more daylight passes through

Air Leakage

Air infiltration

Lower means less air passes through the assembly

Window Repair vs Replacement: A Cost & Condition Decision Guide

Repair makes the most sense when the problem is localized and the surrounding frame remains sound; replacement becomes more compelling when failures are structural, repeated or whole-window performance is poor.

Quick answers

Window replacement FAQs

Concise answers first; source details stay visible elsewhere on the page.

What is the average cost to replace a window in 2026?

Modernize reports a national average of $1,047 per window in its 2026 dataset, while other datasets show wider ranges. Use that figure as a benchmark rather than a guaranteed quote.

How much is labor for window replacement?

Angi's 2026 guide lists typical labor at about $100–$300 per window for standard replacement work, with complex jobs potentially costing more.

Do ENERGY STAR windows save money?

ENERGY STAR reports average savings of up to 13% on household energy bills in the stated single-pane replacement comparison, but real savings vary by climate, home and installation.

Is a lower U-Factor better?

For insulation, yes: NFRC describes a lower U-Factor as better at keeping heat from escaping.
