Double-hung windows in Kingsport, Tennessee
Two vertically sliding sashes; both the top and bottom sash open. For Kingsport's mixed-age housing stock (58.1% of homes predate 1980), double-hung window replacement is a common project — and in the ENERGY STAR North-Central zone, the number that matters most is a low U-factor (≤ 0.25) to keep heat in.
Short answer
Double-hung windows in Kingsport typically cost $605–$2,750 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 Kingsport 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 Kingsport's climate
Kingsport sits in the ENERGY STAR North-Central zone (IECC zone 4A (mixed, moist), Sullivan County), where the priority is a low U-factor (≤ 0.25) to keep heat in.
Double-hung sashes seal against weatherstripping as they slide, so they have more potential air-leakage paths than hinged styles. In the North-Central zone, prioritize a well-built unit and a low U-factor (≤ 0.25) to offset that.

Rebates & incentives in Tennessee
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.
Tennessee's IRA Home Energy Rebates are administered by TDEC's Office of Energy Programs (the state energy office); the state's allocation was approved but the consumer-facing HOMES/HEAR programs had not launched as of mid-2026. Check TDEC for current status before promising rebates. See our Kingsport guide for the full program list.
