Estimates only
The calculators on HomeJobCalc give estimates for planning and shopping. They rely on the measurements you enter and on typical material sizes, densities and waste allowances. Real projects vary, so results may differ from the quantity you actually need.
Not professional advice
Nothing on this site is engineering, construction, legal or safety advice. Confirm quantities, structural requirements, permits and local building codes with a qualified professional or your local authority before you buy materials or begin work.
No warranty
The site and its calculators are provided “as is” without any warranty of accuracy, completeness or fitness for a particular purpose. We work to keep the formulas correct, but we cannot guarantee that they are free of errors.
Limitation of liability
To the fullest extent permitted by law, HomeJobCalc is not liable for any loss, cost or damage arising from the use of, or reliance on, the calculators or other content, including the cost of ordering too much or too little material.
Use of the site
You may use the calculators for personal and business purposes. Please do not copy the site’s content in bulk, or try to disrupt the service.
Links and advertising
The site may display advertising and may link to third-party websites. We do not control or endorse third-party content.
