Replacing a window costs $450 to $1,400 per window installed in 2026, and a whole-house job for 10–15 windows usually lands between $6,000 and $18,000. Where you fall depends on the frame material, the glass package, the window size and style, and whether the old openings need carpentry before the new units go in.
We build websites and lead systems for home-improvement contractors, including window and door installers, so we see the real quotes that go out. This is the honest breakdown, including the cases where you should repair instead of replace.
The default for most homes. Energy-efficient, low maintenance, and the price point most quotes are built around. Standard sizes in a sound opening install fast, which keeps labor down.
Stronger and more stable than vinyl, better in extreme climates, and a step up in price. A common upgrade when a homeowner wants longevity without going to wood.
Wood-clad, bay, bow, casement, and large picture windows. The look and the size both add cost, and custom orders carry longer lead times. Historic homes often require these by code or HOA rule.
Doing the whole house at once usually earns a per-window discount over a one-off. Budget extra if several openings have rot or the trim and siding need to be opened up.
Replacement isn't always the answer. Consider a repair when:
Replace when the frames are rotted, the windows are single-pane, or the air leaks are costing you more in heating and cooling than the job will. Get at least two quotes — and read them line by line, because "installed" sometimes hides disposal and trim fees.

Most run $450–$1,400 installed. Standard vinyl double-hung sits low; large, custom, or wood-clad windows push high.
A typical 10–15 window home runs $6,000–$18,000. Window count, material, and any frame repair drive the spread.
Often, yes. If the frame is sound and only the glass seal or a balance failed, a $75–$300 repair beats a full replacement.
