Terms of use

Information, not professional advice

Guides and tools are for planning and education. Calculator results are estimates based on the assumptions shown with them. They are not architectural, engineering, electrical, plumbing, legal or financial advice. Confirm quantities with your supplier and hire licensed professionals where the law or safety requires it.

AI visualizations

Images produced by AI design tools are conceptual illustrations. They are not accurate drawings and may show things that cannot be built as pictured.

Your content

You keep the rights to photos and projects you upload or create. You grant us only what is needed to process and display them to you, and to anyone you share a link with.

Our content

Text, diagrams and tools are ours or licensed to us. Photographs belong to their credited photographers. You may link to any page; you may not republish guides or scrape the site.

Liability

The site is provided as is. To the extent permitted by law we are not liable for losses arising from reliance on estimates or guides.
