Notes
- Where the number comes from. The national price for a window replacement is $750 per window — replacement window pricing published for 2026, $450–$1,400 per window installed. Labor is about 35% of that. Glaziers near Washington, DC average $66,770 a year against a U.S. mean of $59,720 — a factor of 1.118 — so the labor half is scaled by that and the material half is not.

- Why the city matters, not just the state. Trade pay moves inside a state as much as it does between states. Crews do not commute across a state to bid a job, and materials ship at national prices either way — so a metro wage is the honest input here and a state average quietly rounds four different cities into one number.
- What is in the price: the window, removal of the old sash or unit, insulation and air sealing around the frame, interior and exterior trim where disturbed, and disposal.
- What is not: rot repair in the opening, structural changes to the size, full-frame replacement where an insert was quoted, and interior painting. These are the lines that turn a $6,248 quote into a $7,810 invoice, so ask about each one before signing.
- Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a per-unit average.

What the quote should include
The lines that turn a quote into an invoice
Ask about each of them before you sign. On a job this size they are the difference between $6,248 and something a quarter higher.
Use it as a bid check, not a quote
This prices an average job in average condition. Access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average.
If a bid lands outside $3,749 – $11,663, that is not automatically wrong — but it is the question worth asking out loud.
