Corrections we can use
Useful corrections identify a specific page and explain what is wrong: a formula assumption, a source link, an outdated licensing reference, a local permit issue, or a quote line item that is consistently missing from the guide.
Anonymous quote examples can be submitted through the quote submission page. They are useful only when the location, project size, quote total, included scope, excluded scope, and quote date are clear.
Corrections we avoid
We do not treat anonymous promotional claims, paid placement requests, or single unverified contractor prices as editorial proof. A real quote example is most useful when personal information is removed and the included scope is clear.
Review process
Corrections are checked against the visible model, official sources where available, internal consistency across related pages, and the practical question a homeowner is trying to answer before requesting local bids.
