Source standards
Claims are drawn from primary manufacturer pages, installation manuals, warranty documents, retailer-sourced product records, cost-aggregator ranges, permit sources, and provider-owned sources before publication.
No invented values
Product specs, prices, installer credentials, availability, ratings, and service claims are left unknown until a source confirms them. Retailer and media sourced figures are labeled as such.
Directory firewall
Payment for a directory listing never changes a profile's verification status, its ordering, or the evidence boundary applied to every provider.
