Good reasons to write

What we can't help with

TrueToolCalc does not offer engineering consulting. We can't design a foundation, size a beam, check whether your slab meets code, or answer questions specific to your project's structure and soil. For anything load-bearing or safety-critical, please work with a licensed engineer or your local building department — the calculators here are planning estimates, not professional advice.

What to include

To help us help you: the page URL, the numbers you entered, the result you got, and (for formula questions) the result you calculated by hand. Screenshots of the calculator with your inputs visible are welcome.

Privacy note

Emailing us is, of course, the one way we receive personal information (your address and whatever you write) — it's used only to reply and handle your request, and is never sold. See our Privacy Policy for how the site itself handles data.
