Replacement Windows in Lawrence, Kansas
Lawrence is University of Kansas country in northeast Kansas — student demand, tornado risk, humid summers, historic stock (Quantrill's raid legacy in civic memory), and growth. About 39.3% of homes predate 1980 and the median year built is 1988. Douglas County is ENERGY STAR North-Central / IECC 4A: both U-factor and a moderate SHGC matter. Replacement here is prairie four-season glass on mixed student and historic openings.
Short answer
In Lawrence, a standard replacement window (double-hung, casement or slider) typically costs $505–$2,875 installed. Bay and bow windows run $2,525–$8,075+, and a sliding patio door $1,515–$5,045. Frame material and the glass package decide where a project lands in that range.

Efficiency requirements for Lawrence's climate
Lawrence sits in the ENERGY STAR North-Central zone (IECC zone 4A (mixed, moist), Douglas County). Under the v7.0 specification, qualifying windows need a U-factor of 0.25 or lower and an SHGC of 0.4 or lower. Mixed climate: good insulation matters most, with a moderate cap on solar gain so summer cooling costs stay in check.

Rebates & incentives in Kansas
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.
Kansas was a late mover on the IRA Home Energy Rebates: the Kansas Energy Office at the Kansas Corporation Commission (KCC), working with contractor HORNE, is still standing up its roughly $40M in HOMES and HEAR funding, and as of mid-2026 the public "Kansas Home Rebates" program is listed as coming soon rather than open to applications. When it launches, window replacement would only qualify indirectly through the whole-home HOMES modeled-savings track, not as a standalone rebate. Confirm current status before relying on it.
- Evergy (Kansas) insulation & air sealing rebates. Evergy's Kansas efficiency rebates cover insulation, air sealing, and duct sealing (roughly up to $1,200 combined depending on rate area) and require a comprehensive energy audit plus a participating contractor. They do not rebate replacement windows directly; windows only help by improving the envelope numbers on an audit. Confirm current amounts and terms. (Evergy Kansas rebate/incentive pages)
- Kansas Gas Service. Kansas Gas Service has run limited residential efficiency and weatherization support over the years but does not offer a dedicated replacement-window rebate. Treat windows as ineligible here unless a specific current program says otherwise. (Kansas Gas Service efficiency program pages)
Kansas has no mandatory statewide residential energy code — state law bars the KCC from enforcing residential energy standards, so adoption is left to local governments; the Wichita metro permits under a locally adopted IRC-based code, and the region's IECC zone 4A (cold winters, hot summers) makes envelope and window performance matter despite the absent state mandate.
