About this site and how we check every figure

Last verified: November 11, 2026 · Written and checked by the DuloCore research team

This site explains window replacement for homeowners in Long Beach, California: what it costs, what the city requires and how to choose the right window. Its main tool is the cost estimator on the home page.

Who runs this site

This site is published by DuloCore, a California home-energy rebate service. Every page is written and checked by the DuloCore research team. We do not install or sell windows, and we do not take payment from installers or manufacturers to appear here. We are not affiliated with the City of Long Beach, Long Beach Utilities, Southern California Edison or the Contractors State License Board.

How we check every figure

• Rules come from the source. Permit steps, energy limits, historic district rules and egress rules are taken from the city’s own bulletins and pages and from the California Energy Commission. Each claim links to the page we read.
• Incentive amounts come from verified records only. We print a rebate or credit amount only when it appears in DuloCore’s verified program catalogue and we have confirmed it on the official program page on the day of publication. When an official page did not confirm an amount, we left the amount out and linked the program instead.
• Ended programs are labelled as ended. The federal window credit is shown as history, not as something you can claim for a 2026 project.
• Costs come from named publishers with dates. We use published cost guides and show each publisher’s own update date. Where sources disagree, we show both and explain why. We do not invent local price multipliers; if no source publishes a Long Beach adjustment, the estimator applies none.
• The estimator shows its working. It multiplies your window count by the cited per-window ranges and says plainly that the result is an estimate, not a quote.
• No reviews or rankings. We do not publish testimonials, star ratings or contractor names on this site.
