Double-hung windows in Oxnard, California

Two vertically sliding sashes; both the top and bottom sash open. For Oxnard's mixed-age housing stock (58.6% of homes predate 1980), double-hung window replacement is a common project — and in the ENERGY STAR South-Central zone, the number that matters most is a low SHGC (≤ 0.23) to block solar heat.

Short answer

Double-hung windows in Oxnard typically cost $775–$3,520 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 Oxnard 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 Oxnard's climate

Oxnard sits in the ENERGY STAR South-Central zone (IECC zone 3C (warm, marine), Ventura 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 South-Central zone, prioritize a well-built unit and low-SHGC glass (≤ 0.23) to offset that.

What Double-hung windows cost in Oxnard

Double-hung window replacement in Oxnard runs $775–$3,520 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. Coastal Ventura labor and materials run above Central Valley averages and closer to LA metro pricing. Title 24 compliance and City of Oxnard or County of Ventura permits add process cost; salt-air hardware upgrades add material cost. Many postwar and mid-century tract homes take insert-style retrofits when frames are sound. With the federal 25C credit expired and no reliable standalone SCE window rebate, payback rests on cooling comfort, smoke-day air sealing, and avoided future seal failures under UV and salt exposure.

That's the national range shifted to Oxnard's cost level using the BEA Regional Price Parity for Oxnard-Thousand Oaks-Ventura, CA (110.5, U.S. = 100; 2024). How we estimate local costs →

Rebates & incentives in California

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.

California's IRA rebates run through the California Energy Commission. The HEAR-funded HEEHRA program (delivered via TECH Clean California / The Switch Is On) launched for income-eligible households, but Phase I single-family rebates were fully reserved statewide as of early 2026, with a waitlist and a Phase II in design. HOMES funds are being routed into the Equitable Building Decarbonization Direct Install program and a Pay-for-Performance program that were not yet issuing rebates as of mid-2026. Confirm current availability first. See our Oxnard guide for the full program list.
