Editorial policy

Sources

We rely on primary sources first: the Pennsylvania Department of Environmental Protection, the U.S. EPA, the U.S. Census Bureau, NOAA, Pennsylvania statutes, and industry standards bodies. Cost figures come from national cost databases and published contractor pricing, and we say which. When a number cannot be verified we leave it out.

Contractor listings

Contractors appear because they publicly serve York County and can be verified through a state directory, a trade association, or a review platform. Listing is not an endorsement, and no contractor pays to be listed.

AI and human review

We use software, including AI tools, to help draft and organize pages. A person reviews every page before it is published and is responsible for its accuracy.

Updates and corrections

Pages show a last-reviewed date. If you find an error, tell us and we will fix it and note the change.
