Hinged / French patio doors in Charleston, West Virginia
One or two swinging door panels, often with divided lites. For Charleston's older housing stock (81.9% of homes predate 1980), hinged / french patio door 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
Hinged / French patio doors in Charleston typically cost $1,985–$6,455 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.

Hinged / French patio doors and Charleston's climate
Charleston sits in the ENERGY STAR North-Central zone (IECC zone 4A (mixed, moist), Kanawha County), where the priority is a low U-factor (≤ 0.25) to keep heat in.
On a hinged / french patio door, air-sealing at the sill and frame is where the energy savings live. Look for a solid compression seal and a well-flashed threshold — plus, in the North-Central zone, an insulated slab and low-U-factor glass in any lites.

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 Charleston guide for the full program list.
