Terms of use

DIYSums provides general project-planning information and material estimates. The tools are not a substitute for a site survey, product instructions, building approval or professional advice. Results depend on the accuracy and completeness of the information you enter.

Sources, prices, products and local rules can change. Estimates may be incomplete, unsuitable for a particular site, or contain errors. Check the cited sources and current manufacturer or supplier information, measure your project independently, and use your own judgement before buying materials or carrying out work.

Nothing on this site is financial, tax, legal, medical, structural or safety advice. Ask an appropriately qualified professional or relevant authority when your project requires one. You are responsible for decisions made using the site.

The site and its estimates are provided without a promise that they will be uninterrupted, error-free or suitable for a particular purpose. To the extent permitted by applicable law, DIYSums disclaims warranties and liability for losses arising from reliance on the site. These terms do not limit rights that cannot lawfully be excluded.
