Window installation runs about $300 to $1,200 per window installed, and a whole-house replacement of 10 to 20 windows lands at roughly $8,000 to $20,000. The spread is wide because three things move the number hard: the window itself, insert versus full-frame installation, and how reachable the opening is.
We run our own home-service companies, so we know how these quotes get built and where the padding hides. This is the honest version — real ranges, what changes them, and the cases where you can skip the contractor entirely.
The most common job. A new window dropped into a sound existing frame on the ground floor. Fast install, lowest labor. This is what most "replace my old windows" quotes are built on.
Frame removed to the studs — needed when wood is rotted, the opening is being resized, or you want new construction-grade flashing. More labor, more carpentry, more cost. Worth it when the old frame is gone.
Picture windows, bay and bow units, fiberglass, or clad-wood. Heavier glass, often two installers, sometimes structural work. The high end of any whole-house number is usually a handful of these.
A contractor is not always the right call:
Hire out the moment it's full-frame, second-story, whole-house, or warranty-dependent. A bad seal costs more to fix than the install saved.
We don't post stock testimonials. On a 15-minute call we screen-share the real dashboards behind our own businesses — live leads, rankings, and the exact page that produced each one. See the proof →
Homeowners read three or four cost pages before they call anyone. Being the contractor whose site answers the money question honestly is how you win the estimate. We build that site — and the AI that books the visit — from $249/month, with a working demo in 48 hours. See the contractor website page, the related window replacement cost guide, and what local SEO costs if you want to rank for these searches yourself.
The per-window ranges above include both the unit and labor. Always confirm whether a quote is "installed" or "materials only," and whether disposal and permits are in or out.
Three. Compare install type and warranty, not just price. The cheapest insert quote and the priciest full-frame quote can be for genuinely different work. More buyer guides live in the homeowner guides hub.
They help, but payback is usually 10-plus years. If energy is the only goal, air-sealing and adding storm windows often beat full replacement on cost. Browse more in the cost guides hub.
If you install windows, send your company name and metro — we'll build a free working demo of a site that turns these searches into booked estimates, within 48 hours.
