Terms of Use

Last updated: November 2, 2026

By using getdiycalcs.com (the "Site") you agree to these terms.

Estimates, not professional advice

The calculators provide estimates for planning and purchasing. Results depend on the information you enter and on typical values (bag yields, coverage, densities) that vary between products and sites. They are not engineering, architectural or legal advice. Always check product labels, follow manufacturer instructions and comply with your local building codes and permit requirements. For structural, electrical, gas or roofing work, consult a licensed professional.

No warranty

The Site is provided "as is" without warranties of any kind. To the fullest extent permitted by law, we are not liable for any loss or damage arising from the use of the Site or its results, including the cost of materials bought based on an estimate.

Content

The text, calculators and design of the Site belong to Juan Antonio Fernández Selma. You may link to any page and share results for personal use. Copying the Site or its calculators in bulk is not allowed.

Links

The Site links to external sources and shows third-party ads. We are not responsible for the content of other websites.
