Have a calculator question, found a possible formula issue, or want to suggest a new construction tool? Send a note to [contact@specmath.com]. We review calculator feedback carefully because even a small material estimate error can matter on a real job.

Typical response time is two to three business days. Please include the calculator name, the dimensions or inputs you used, the result you expected, and the result you saw. That context helps us reproduce the issue and make the tool better for other contractors, tradespeople, and DIYers.
