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 Portland, ME average $50,250 a year against a U.S. mean of $59,720 — a factor of 0.841 — so the labor half is scaled by that and the material half is not. Source: BLS does not publish a metro figure for glaziers near Portland, ME, so this is the Maine state average, SOC 47-2121.
- This one falls back to a wider average. BLS did not publish a metro-level wage for this trade near Portland, ME, so the figure above is a state average. It is still the right order of magnitude, but a local bid carries more weight here than it would in a large metro where the survey has more responses.
- 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 $2,833 quote into a $3,542 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.

Ask about each of them before you sign. On a job this size they are the difference between $2,833 and something a quarter higher.

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 $1,700 – $5,289, that is not automatically wrong — but it is the question worth asking out loud.
