How this Pennsylvania 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
- $574–$1,260 per window installed · $5,740–$12,600 for a 10-window project (before bulk discount)
