Corrections and data questions

If a number on CostRule looks wrong, or you have information that would improve a cost estimate — a more current material price, a labor-hours source we haven’t seen — send it to [email protected]. Include the page URL and, where possible, the source you’re pointing to. Corrections are the fastest way this data gets better.

Press and data requests

For questions about the underlying data set, the calculation methodology, or requests to reference CostRule’s figures — each one drawn from CostRule’s analysis of BLS wage data and collected material prices — in your own reporting, use the same address: [email protected].

General inquiries

For anything else — feedback on the site, a category you’d like to see covered, or a question about how a specific number was calculated — [email protected] reaches Keydams, which publishes the site.

What to expect

There’s no dedicated support desk behind CostRule, so response times vary. Corrections that point to a clear source get looked at first.
