Bay & bow windows in Mobile, Alabama

Is a Bay & bow window right for a Mobile 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 Mobile's climate

Mobile sits in the ENERGY STAR Southern zone (IECC zone 2A (hot, humid), Mobile 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.

New to these numbers? See our plain-English guide to U-factor and SHGC and the full bay & bow guide.

What Bay & bow windows cost in Mobile

Bay & bow window replacement in Mobile runs $2,465–$7,890+ installed. 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. Coastal impact packages cost more than inland Alabama standard glass. Itemize product approval, DP rating, labor, and permit. Federal 25C is gone; Alabama Power has no reliable window rebate. Payback is insurance, storm resilience, and cooling savings.

That's the national range shifted to Mobile's cost level using the BEA Regional Price Parity for Mobile, AL (88.1, U.S. = 100; 2024). How we estimate local costs →

Rebates & incentives in Alabama

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.

Alabama's IRA Home Energy Rebates are administered by ADECA (Alabama Department of Economic and Community Affairs), which as of mid-2026 still lists the HOMES and HEAR programs as under development with no confirmed date for when households can access rebates. If and when they open, windows would generally qualify only through the whole-home HOMES modeled-savings pathway rather than as a direct rebate. Confirm current status with ADECA before relying on it. See our Mobile guide for the full program list.
