Corrections
If a figure looks wrong, tell us. Include the page, the number you disputed, and what you were actually quoted. A real invoice is the single most useful thing you can send us, and it is what moves a range fastest.
Write to corrections@costhomebook.example.
Everything else
Advertising, contractor listings and press: hello@costhomebook.example.
What we cannot do
We cannot quote your job, recommend a specific contractor, mediate a dispute, or advise on a contract you have already signed. For those you need a licensed professional in your state.
