Double-hung windows in Hattiesburg, Mississippi
Two vertically sliding sashes; both the top and bottom sash open. For Hattiesburg's mixed-age housing stock (50.4% 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 Hattiesburg typically cost $615–$2,790 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 Hattiesburg 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 Hattiesburg's climate
Hattiesburg sits in the ENERGY STAR Southern zone (IECC zone 2A (hot, humid), Forrest 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 Mississippi
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.
Mississippi's IRA Home Energy Rebates are administered through the Mississippi Development Authority Office of Energy (Energy & Natural Resources). 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 at mississippi.org / MDA 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 Hattiesburg guide for the full program list.
