Terms of Use
Last updated: 25 October 2026. By using this website you accept these terms.
The service
DIY Home Calculators provides free online calculators, guides and related content for planning home improvement projects. The tools produce planning estimates based on the measurements and options you enter.
Estimates, not guarantees
Calculator results are estimates for purchasing and planning. Actual material requirements depend on your site conditions, product coverage, installation method and workmanship. Always verify coverage against the manufacturer's label for the exact product you buy, and measure your own project carefully. We are not responsible for shortages, surpluses, project outcomes or costs arising from reliance on an estimate.
Safety and professional work
Nothing on this site is professional engineering, architectural or trade advice. Structural work, roofing, electrical, plumbing and gas work may require permits and qualified professionals under your local rules. Follow all product safety instructions and local building codes.
Intellectual property
The content of this site — text, design and calculator logic — belongs to us or our licensors and is provided for your personal, non-commercial use. You may link to our pages. You may not republish substantial parts of the site, or copy the calculators, without written permission.
Acceptable use
Do not misuse the site: no automated scraping that burdens the service, no attempts to disrupt or gain unauthorised access, and no use of the site or its content to mislead others.
External links and advertising
The site contains advertising and may link to third-party websites. We are not responsible for the content, products or practices of third parties.
Liability
To the maximum extent permitted by law, the site is provided 'as is' without warranties of any kind, and our liability for any claim arising from use of the site is limited to the extent permitted by law.
