Terms of Use

These terms are between you and Quarles Enterprises LLC, an Alabama limited liability company doing business as EstimateMix ("we," "us," or "our").

These terms haven't been reviewed by a lawyer. Have them reviewed for your specific situation before relying on them.

Using this site

EstimateMix's calculators are free to use for personal and professional project planning. You may link to any page on this site. You may not scrape, republish, or redistribute the site's content or calculator engine as your own without permission.

Estimates only

Every calculator on this site produces an estimate based on standard formulas, published bag yields, and typical material densities. Actual quantities can vary with waste, site conditions, supplier-specific yields, and measurement error. See our full disclaimer for details on the limits of these tools.

No professional advice

Nothing on this site is engineering, structural, or legal advice. Footing depth, rebar, wall design, and code compliance depend on your local jurisdiction and site conditions — consult a licensed contractor, engineer, or your local building department before construction.

No warranty

This site and its calculators are provided "as is," without warranty of any kind, express or implied. We don't guarantee the calculators will be error-free, uninterrupted, or fit for a particular purpose.

Limitation of liability

To the fullest extent permitted by law, we are not liable for any direct, indirect, incidental, or consequential damages arising from your use of, or reliance on, this site or its calculators, including over-ordering, under-ordering, or project cost overruns.

Governing law

These terms are governed by the laws of the State of Alabama, without regard to its conflict-of-laws principles.

Changes

We may update these terms as the site changes. Continued use of the site after a change means you accept the updated terms.
