Terms of Service
By using ConstructTools.com you agree to these terms. If you do not agree, please do not use the site.
Estimates only — not professional advice
Our calculators and guides provide estimates for planning purposes. They are not a structural design, a code-compliance check or a contractor's quote. Material quantities, costs and structural requirements depend on local codes, site conditions, suppliers and workmanship. Always have designs checked by a licensed engineer and confirm quantities and prices with your contractor or supplier before buying materials or building.
No warranty
The site is provided "as is". We work hard to keep formulas and reference values accurate, but we do not guarantee that results are complete, correct or suitable for a particular purpose.
Limitation of liability
To the extent permitted by law, ConstructTools and its author are not liable for any loss or damage arising from the use of, or reliance on, the calculators or content on this site.
Intellectual property
Text, calculators, code and design on this site belong to ConstructTools. You may link to any page and share results for personal or professional use, but you may not copy the site or its tools wholesale.
Third-party links
Links to other websites are provided for convenience. We are not responsible for their content or practices.
