Reporting a wrong figure

This is the most useful message you can send. Include the page URL, the figure you believe is wrong, and if you have it, the source that shows the right one. Corrections to wage, index and calculated numbers go to the front of the queue.

Contractors

If a calculation on this site misrepresents how your trade actually prices work, tell us which assumption is off and why. Hours per square, crew composition and overhead multipliers are the ones most worth arguing about, and we would rather publish a corrected assumption than a comfortable one.

We do not sell placement, do not accept paid coverage, and do not take referral fees, so there is nothing to pitch here beyond the numbers.
