Updated September 2026 · Sourced from BLS, FRED & EIA

Window replacement in Maine costs $597–$1,267 per window installed in 2026 — near the national average (Moderate cost tier) — or $5,970–$12,670 for a typical 10-window project before bulk discounts.

Maine's harsh winters make window quality critical. Triple-pane glass is worth considering for much of the state, and energy savings from replacement are among the highest in the nation. Many older homes still have original single-pane windows.

How this Maine estimate is calculated

Based on BLS, FRED & EIA data

Labor, weatherproofing and price escalation come from federal data. The base material cost does not — and we say so below rather than rounding it into the same sentence. Reference window: standard vinyl double-hung, retrofit install.

Labor: 2 man-hrs (NREL/Craftsman) × $29/hr national carpenter wage (BLS OEWS, SOC 47-2031) × 2.84 contractor markup = $165
Materials: Vinyl frame + Low-E glass, escalated 4.9% since 2025 by the FRED producer price index. The base cost this escalates is not independently sourced — it is the largest single term in the estimate and the one we cannot yet cite. Retail listings for the products named in our tiers put a comparable unit at $284–$379, which brackets it. How we are trying to close that.
Weatherproofing: $20–$35 per opening — flashing tape, foam, backer rod and caulk, priced per opening rather than as a percentage of the window (DuPont GREAT STUFF)
Installed cost: $597–$1,267 per window installed · $5,970–$12,670 for a 10-window project (before bulk discount)
