Bay & bow windows in Savannah, Georgia

Multi-unit assemblies that project outward — bay (3 units, angled) or bow (4–6 units, curved). For Savannah's mixed-age housing stock (59.9% of homes predate 1980), bay & bow window replacement is a common project — and in the ENERGY STAR Southern zone, the number that matters most is a low SHGC (≤ 0.23) to block solar heat.

Short answer

Bay & bow windows in Savannah typically cost $2,665–$8,525+ 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 Savannah 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 Savannah's climate

Savannah sits in the ENERGY STAR Southern zone (IECC zone 2A (hot, humid), Chatham County), where the priority is a low SHGC (≤ 0.23) to block solar heat.

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 Southern-zone comfort.

Rebates & incentives in Georgia

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.

Georgia's Home Energy Rebates (both the Home Efficiency Rebates and HEAR tracks) are live statewide, administered by the Georgia Environmental Finance Authority (GEFA), with more than $25 million delivered as of spring 2026. Windows fit best under the Home Efficiency Rebates track as part of a whole-home retrofit with modeled energy savings — federal guidance changes taking effect in late 2026 may alter program details, so confirm current rules. See our Savannah guide for the full program list.
