Awning windows in Knoxville, Tennessee
Top-hinged sash that opens outward from the bottom. For Knoxville's mixed-age housing stock (59.4% of homes predate 1980), awning 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
Awning windows in Knoxville typically cost $345–$1,575 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.

Awning windows and Knoxville's climate
Knoxville sits in the ENERGY STAR North-Central zone (IECC zone 4A (mixed, moist), Knox County), where the priority is a low U-factor (≤ 0.25) to keep heat in.
A awning closes against a compression seal — the tightest of any operable window. In the North-Central zone's cold winters, where air leakage drives heating loss, that seal is a real advantage.

What Awning windows cost in Knoxville
Awning window replacement in Knoxville runs $345–$1,575 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. Knoxville window pricing tends to land below what national averages suggest, because labor costs in East Tennessee run under those of coastal metros — but the age of the stock pushes many projects toward the expensive end of the local range anyway. An insert replacement in a 1970s Cedar Bluff or Halls ranch with sound frames is the simple case. Full-frame work in a pre-1940 Fourth & Gill or Old North Knoxville house costs meaningfully more: rot repair in a humid climate, weight-pocket insulation, out-of-square openings, and custom sizing all add labor, and if the house sits in an H-1 overlay, the Historic Zoning Commission may require wood or approved wood-composite units that cost well above vinyl. The valley's humidity also makes flashing and installation quality matter more than brand — a mid-tier window installed carefully beats a premium unit installed badly here. Get itemized quotes and be wary of single-number pricing after a long in-home pitch.

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 Knoxville guide for the full program list.
