Bay & bow windows in Morgantown, West Virginia
Multi-unit assemblies that project outward — bay (3 units, angled) or bow (4–6 units, curved). For Morgantown's older housing stock (65.6% of homes predate 1980), bay & bow window replacement is a common project — and in the ENERGY STAR North-Central zone, the number that matters most is a low U-factor (≤ 0.25) to keep heat in.
Short answer
Bay & bow windows in Morgantown typically cost $2,610–$8,355+ installed per opening. The low end is a mid-grade vinyl insert from a regional installer; the top is a premium frame, a full-frame installation, or a full-service national brand.

Is a Bay & bow window right for a Morgantown home?
Fixed center with operable flankers (bay) or a curved run of units (bow).
Where it fits:
- Adding interior space, light, and a seat or shelf
- Street-facing façade upgrades
What to weigh:
- A structural project, not a swap — support, roofing, and insulation of the projection drive cost
- Highest cost band of common window projects
Bay & bow windows and Morgantown's climate
Morgantown sits in the ENERGY STAR North-Central zone (IECC zone 4A (mixed, moist), Monongalia County), where the priority is a low U-factor (≤ 0.25) to keep heat in.
Because a bay or bow projects beyond the wall, its roof and floor are a thermal weak point — insulating that projection well matters as much as the glass for North-Central-zone comfort.

Rebates & incentives in West Virginia
The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.
West Virginia's IRA Home Energy Rebates are administered through the West Virginia Office of Energy (Department of Economic Development). As of mid-2026 consumer-facing HOMES/HEAR pathways were not clearly open for standard single-family window projects — treat status as pending and confirm with the WV Office of Energy before promising rebate money. Windows would generally fit only inside a whole-home modeled-savings track when programs launch, not as a retail per-window check. See our Morgantown guide for the full program list.
