Contact us

One inbox, read by a human. Corrections get priority.

the fastest way to reach us We aim to reply within two business days. There's no contact form here on purpose — no lead capture, no CRM, no reselling your details.

Found a number that's wrong?

Please tell us. Include the calculator, the inputs you used, and what you believe the correct figure is — a supplier quote, a manufacturer spec sheet, or a code reference is ideal. Prices drift constantly and regional pricing is approximate, so real-world quotes are the most useful corrections we get. Verified fixes go live and the page's review date is updated.

Want a calculator we don't have?

Tell us the project and what you're trying to buy or budget for. We build tools where the math is standardized enough to be genuinely useful — flooring, framing, and finish work are the areas we get asked about most.

Advertising, partnerships, and press

Same address. This site is supported by display advertising and clearly labeled retailer links; we don't publish sponsored articles, guest posts, or paid links inside our editorial content, so please don't pitch those.

Before you write

Our methodology page documents every formula, waste factor, price source, and the state cost index in full — most "where did this number come from?" questions are answered there. We can't provide engineering advice, structural sizing, or code interpretation for a specific project; that needs a licensed professional who can see your site.
