Disclaimer & Terms of Use

Not Professional Advice

CalcBuild provides free construction material estimation calculators for informational and educational purposes only. These tools are designed to assist with preliminary planning and rough material estimates for common construction projects.

The calculators, results, and information provided by CalcBuild do not constitute and should not be relied upon as professional engineering, architectural, construction, or building code compliance advice. CalcBuild is not a licensed engineering firm, architecture firm, general contractor, or building official.

Reference Data

Where noted, CalcBuild uses reference values (such as material densities, thermal properties, or coverage rates) sourced from publicly available industry standards and publications, including those from ASTM International, ASHRAE, DOE, ICC (International Building Code/Residential Code), and TCNA.

These references are provided for informational purposes to identify the sources of general reference data. Referencing these standards does not imply that CalcBuild is endorsed by, affiliated with, or certified by any of these organizations. Actual material properties may vary significantly from published reference values based on manufacturer, region, and site conditions.

Accuracy & Limitations

Calculator results are estimates based on general assumptions and standard reference values. Actual material quantities may vary based on site conditions, material variations, waste factors, installation methods, local building codes, and other factors not captured by these tools.

Always add an appropriate waste or overage buffer (typically 5-15%) to calculated material quantities.

User Responsibility

You are solely responsible for:

• Verifying all calculations and material quantities before purchasing or using materials
• Ensuring compliance with local building codes and regulations
• Obtaining necessary permits and inspections
• Consulting with licensed professionals (engineers, architects, contractors, building officials) for any construction project
• Following proper safety protocols and procedures

No Warranty

CalcBuild is provided on an "AS IS" and "AS AVAILABLE" basis without warranties of any kind, either express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement.

Limitation of Liability

To the fullest extent permitted by applicable law, CalcBuild and its operators shall not be liable for any direct, indirect, incidental, consequential, or special damages arising from or related to the use of these calculators, including but not limited to material waste, cost overruns, construction defects, property damage, personal injury, or any other losses.

Changes

We may update this disclaimer from time to time. The "Last updated" date at the top of this page reflects the most recent revision.
