Terms of Use

Last updated: 7 July 2026

By using homeprojectcalcs.com you agree to these terms. If you don’t agree, don’t use the site.

Estimates, not guarantees

Every calculator on this site produces a planning estimate based on industry-standard formulas, typical yields, and manufacturer coverage rates. Real-world quantities vary with site conditions, product brands, regional packaging, workmanship, and layout. Always verify quantities with your supplier and check your local building code before purchasing materials or starting construction. Building codes differ by country, state, and municipality; nothing on this site is a substitute for a permit, an inspection, or the judgment of a qualified professional.

No warranty

The site and its calculators are provided “as is”, without warranty of any kind, express or implied — including fitness for a particular purpose and accuracy of results. We work hard to keep formulas correct and we fix reported errors quickly, but we do not warrant that any result is error-free.

Limitation of liability

To the maximum extent permitted by law, HomeProjectCalcs and its operator are not liable for any loss or damage arising from use of the site — including over- or under-ordered materials, construction defects, project delays, or code violations. Your sole remedy for dissatisfaction with the site is to stop using it.

Not professional advice

Content on this site is general information for homeowners and DIYers. It is not engineering, architectural, or construction advice. Structural work (framing, roofs, retaining walls, concrete) can have safety implications — when in doubt, hire a professional.

Acceptable use and content

You may link to any page freely. You may not scrape the site into a competing product, remove attributions, or misrepresent our results as certified take-offs. Site content and code are © HomeProjectCalcs; formulas themselves are industry knowledge and not claimed as proprietary.

Changes

We may update these terms; the date above reflects the latest revision. Continued use after a change constitutes acceptance. Questions: contact page.
