Response time

We typically respond to emails within 2-3 business days. For urgent calculation questions, please consult with a professional contractor or building supplier who can provide immediate guidance for your specific project.

Before sending a project-specific question

Material Tally can help improve the clarity of calculator explanations, but we cannot inspect a job site or approve a final purchase. If you are trying to decide how much material to buy, start by saving the measurements you entered, the waste factor used, and the product assumptions such as coverage per gallon, concrete bag yield, flooring box coverage, or gravel density.

For structural, code-sensitive, or safety-related work, contact a qualified local professional. For product-specific questions, contact the supplier or manufacturer and compare their recommendation with your Material Tally estimate. The material estimate checklist is a good starting point before you send a question or request a quote.

What we can help with

We welcome messages about unclear instructions, broken links, display problems, calculation assumptions that need better explanation, and ideas for future guides. If a page could be easier to understand on a phone, if a result label feels confusing, or if a common project material is missing from the site, that feedback is useful.

We cannot provide individualized construction approval, confirm property-line decisions, inspect structural designs, or replace a supplier quote. For those situations, use Material Tally as a preparation tool. Bring the calculator result, your measurements, and the related guide to a local supplier or contractor so the conversation starts with clear information.

If you are suggesting a new calculator, include the material type, the units people usually buy it in, the inputs you would expect to enter, and any product-specific assumptions that should be visible. That helps us decide whether the idea fits Material Tally and how it should be explained.

Helpful links before contacting us

If your question is about how a calculator works, the fastest path is often to open the related guide from the calculator page. Each guide explains the measurement method, why the waste factor matters, and which product-specific number to verify before purchasing. The articles hub groups all guides by topic.

If your question is about site policies, review the privacy policy, terms of service, and calculator disclaimer. Those pages explain how estimates should be used and where professional verification is still needed.
