Every windows question, answered.

It costs $5k–$15k to replace windows in the US. Size, materials, region, and scope drive the spread; expect the midpoint to land near $10k for a typical job.

The national average to replace windows is about $10k. Half of homeowners pay between $5k and $15k depending on scope, materials, and region.

Small jobs run roughly $5k; mid-size jobs land near $10k; large or premium scope can exceed $15k. Size, finish level, and labor rate are the three biggest cost levers.

For a small home, expect to pay near the low end - roughly $5k–$6.5k. Less square footage, fewer fixtures, and simpler access all cut labor hours.

For a large home, costs typically run $12k–$15k or more. Larger areas mean more materials, more labor hours, and often premium finishes that bump the per-unit cost.

The cheapest window options start near $5k. Save by choosing builder-grade materials, keeping the existing layout, and bundling the work in the shoulder season.
