Replacement Windows in Sherman, Texas
Sherman sits in Texoma / Red River north Texas — heat, hail, tornado risk, and a growth boom tied to major industrial investment (including semiconductor manufacturing). This page represents the broader Sherman–Denison market. Of the city's housing units, 51.8% predate 1980 and the median year built is 1978. Grayson County is ENERGY STAR South-Central / IECC 3A: low SHGC for cooling with a real U-factor.
Short answer
In Sherman, a standard replacement window (double-hung, casement or slider) typically costs $525–$2,990 installed. Bay and bow windows run $2,625–$8,400+, and a sliding patio door $1,575–$5,250. Frame material and the glass package decide where a project lands in that range.

Efficiency requirements for Sherman's climate
Sherman sits in the ENERGY STAR South-Central zone (IECC zone 3A (warm, moist), Grayson 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.

Rebates & incentives in Texas
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.
Texas accepted IRA rebate funding but program rollout has lagged; check the State Energy Conservation Office for current status before counting on it.
- Utility efficiency programs (Oncor service area). Oncor and other Texas utilities fund weatherization and efficiency incentives through participating contractors; window measures are typically part of whole-home packages. (Oncor / TX utility program pages)
Texas adopts the IECC statewide with amendments; coastal counties add TDI windstorm certification requirements (WPI-8) that affect window product choice and insurance eligibility.
