Contact us
RenoMath is run by a small team, and email is the only channel we use. There is no form on this page on purpose: a form needs a server, a spam filter and a database, and everything else on this site runs without them.

We read everything and reply to most messages within two working days.
What to write about
- A wrong number. Tell us the calculator, the values you entered and what you expected instead. If a formula is wrong we will fix it and say so on the page.
- A missing calculator. If you keep doing the same estimate on paper, describe the inputs and the result you need and we will consider building it.
- A regional problem. Coverage rates and prices differ outside the United States. If you are working in metric or in another market, tell us which figures look wrong and we will add the right ones.
- Advertising, licensing or press. Use the same address and put the subject in the first line.
What we cannot do
We cannot review your plans, size a structural beam, price a specific job in your city, or recommend a contractor. Those questions need someone who has seen the building. See our terms for the limits of these tools.
Corrections policy
When a formula turns out to be wrong, we correct the page and note the change rather than quietly editing it. Estimates you already wrote down may move as a result — check them again if the change affects work you have not started.
Privacy
Emails you send us are kept only as long as it takes to answer them. What the site itself collects is described in the privacy policy.
