Orange County, CA · Updated 2026 · Ranges from our cost guides — your quote will vary by contractor and scope
How this calculator works: it combines the cost bands published in our Orange County cost guides with a few choices about your project. The output is a range — low, typical, high — with the assumptions listed. It is a planning tool, not a contractor bid.
Your project
What drives the cost
- Window type — vinyl retrofit $500–$800, fiberglass $800–$1,200, wood/wood-clad $1,000–$2,000+ installed (per our 2026 window guide).
- Install method — retrofit fits existing frames; full-frame with stucco work runs $800–$1,500+ per window.
- Count & doors — whole-house (10 standard windows) $6,000–$12,000; sliding patio doors $1,500–$3,500 each.
- Energy specs — compare U-factor and SHGC line by line; a cheaper window with worse specs costs more over time.
- Volume pricing — full-house jobs often negotiate better per-window pricing than one-offs.
Estimate, not a quote
These numbers are estimates only — not a quote, not a bid. Bands are computed from the cost ranges published in our Orange County cost guides (2026), which are themselves compiled from contractor-published pricing and industry data. Your actual price depends on scope, materials, access, timing, and the contractor. Always get 2–3 written quotes and compare the scope line by line, not just the total. We don't sell services and we have no contractor relationships.
