How we work
Every ranking page on this directory is jointly produced by a staff writer and an expert reviewer. The writer is responsible for assembling the article from research, interviews, and the underlying data; the expert reviewer is responsible for signing off on technical accuracy, pricing realism, and industry-specific claims before the page publishes.
For most pages, the writer is one of our three staff writers and the reviewer is the category expert (Marcus Chen for HVAC, Robert Sullivan for plumbing, and so on). For cross-category pages (city overviews, state overviews), the reviewer defaults to our Methodology Lead, Dr. Aisha Williams. Quarterly market reports pair Daniel Reyes as writer with the matching category expert as reviewer.
If you spot something on a ranking page that doesn't match field reality, please write to help@serviceagent.ai with the URL and the issue. We route corrections directly to the page's expert reviewer and respond within one business day.
Full formula + audit details are on the methodology page.
