Double-hung windows in Mobile, Alabama

Two vertically sliding sashes; both the top and bottom sash open. For Mobile's older housing stock (64.8% of homes predate 1980), double-hung 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

Double-hung windows in Mobile typically cost $615–$2,805 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 Double-hung window right for a Mobile home?

Both sashes slide vertically and typically tilt inward for cleaning.

Where it fits:

  • Traditional and historic home styles
  • Rooms facing walkways, porches, or patios (no outward projection)
  • Easy cleaning from inside on upper floors

What to weigh:

  • More potential air-leakage paths than hinged styles at equal quality
  • Half the opening ventilates at any one time

Double-hung 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.

Double-hung sashes seal against weatherstripping as they slide, so they have more potential air-leakage paths than hinged styles. In the Southern zone, prioritize a well-built unit and low-SHGC glass (≤ 0.23) to offset that.

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.
