Replacement Windows in Montgomery, Alabama
Montgomery is Alabama's capital on the Alabama River — humid subtropical summers, tornado risk, and older capital-city stock. Of the city's housing units, 55.5% predate 1980 and the median year built is 1977. Montgomery County is ENERGY STAR South-Central / IECC 3A: low SHGC for cooling with real winter nights that still need a solid U-factor. Covered from RBA Alabama territory. Replacement here is humidity and storm resilience on aging openings — not Gulf Coast Mobile impact code.
Short answer
In Montgomery, a standard replacement window (double-hung, casement or slider) typically costs $500–$2,855 installed. Bay and bow windows run $2,510–$8,035+, and a sliding patio door $1,505–$5,020. Frame material and the glass package decide where a project lands in that range.

- South-Central / 3A: U ≤ 0.28, SHGC ≤ 0.23 under ENERGY STAR v7.0.
- Older capital stock: lead-safe work and non-standard openings common.
- Tornado and severe-storm exposure — laminated glass is a rational upgrade.
- Alabama Power no window rebate; ADECA IRA pending; 25C expired.

Efficiency requirements for Montgomery's climate
Montgomery sits in the ENERGY STAR South-Central zone (IECC zone 3A (warm, moist), Montgomery County). Under the v7.0 specification, qualifying windows need a U-factor of 0.28 or lower and an SHGC of 0.23 or lower. Cooling-leaning climate: blocking solar heat gain (low SHGC) matters as much as insulation.

What replacement windows cost here
Capital-city pricing is moderate. Age of openings drives spreads. Federal 25C is gone; Alabama Power does not offer a reliable window rebate. Itemize every bid.

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.
- Alabama Power (Southern Company) residential rebates. Alabama Power's current residential rebates target smart thermostats, heat pumps, water heaters, and EV chargers — not replacement windows. Aggregator sites that show a "$600 windows" figure are echoing the now-expired federal 25C credit, not an Alabama Power offer. Do not count on a direct utility window rebate here.

Alabama's residential energy code, adopted by the Alabama Energy and Residential Codes Board, is based on the 2015 IECC but weakened by state amendments (roughly better than 2009 IECC, short of full 2015 IECC); the Huntsville/Madison County metro sits in IECC climate zone 3A, a mixed-humid climate where cooling loads and solar heat gain drive window spec.

Montgomery window replacement FAQ
›Do I need a permit to replace windows in Montgomery?
Usually yes for full replacement. City of Montgomery Inspection Department / building permits apply. Confirm the installer pulls the permit.
›What efficiency numbers should windows hit?
ENERGY STAR South-Central and IECC 3A: U-factor 0.28 or lower and SHGC 0.23 or lower. Read the NFRC label. This is not Mobile's Southern coastal package.
›Are there rebates?
Federal 25C expired December 31, 2025. ADECA IRA programs were still under development as of mid-2026; Alabama Power does not rebate windows standalone. Budget without incentives.
›How is Montgomery different from Mobile?
Inland capital 3A South-Central vs Gulf Coast 2A Southern with hurricane/WBDR pressure. Impact and salt-air hardware matter more in Mobile; humidity and tornado resilience matter here.
