Construction Calculators

Terms of Service

This document is provided as a template baseline. For legal certainty specific to your jurisdiction, consult a qualified lawyer. Last updated: August 2026.

These Terms of Service ("Terms") govern your use of [SITE_NAME], operated by [BUSINESS_NAME] ("we," "us," or "our"). By accessing or using this site, including any of its calculators, you agree to be bound by these Terms. If you do not agree, please do not use the site.

1. Use of the site

[SITE_NAME] is provided for personal, non-commercial use in planning DIY home improvement projects. Small contractors and tradespeople may use our estimates as a starting point for their own quotes, but must independently verify all figures before relying on them commercially. You agree not to scrape, use automated tools to extract data beyond ordinary personal use, or resell or redistribute calculator outputs as your own product or service.

2. Calculator estimates are informational only

Every estimate produced by this site is a planning aid, not professional advice. It is not a substitute for consultation with a licensed contractor, structural engineer, or your local building or planning authority. Prices reflect retailer data current as of [LAST_UPDATED_DATE] and may vary by location, season, and supplier. Actual material quantities, costs, and permit requirements vary by project, jurisdiction, and time, and you assume full responsibility for all construction, permitting, and safety decisions made using this site's output.

3. Regional legal notices

4. Intellectual property

All content on this site — including calculator formulas, written methodology, page design, and text — is © [BUSINESS_NAME] 2026, unless otherwise noted. You may reference our published methodology with attribution, but may not reproduce it wholesale or represent it as your own. Trademarks of named retailers and brands referenced on this site (including Trex, Behr, Home Depot, Wickes, Bunnings, and Rona) belong to their respective owners and are used for identification purposes only; no affiliation or endorsement is implied.

5. Third-party links and affiliate relationships

This site participates in the Amazon Associates program and links to other third-party retailers. If you click one of these links and make a purchase, we may earn a commission at no extra cost to you. We do not control the content, policies, or terms of any third-party site, and your interactions with those sites are governed by their own terms and privacy policies, not ours.

6. Disclaimers and limitation of liability

This site is provided "as is" and "as available," without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that any estimate is accurate for your specific project.

To the maximum extent permitted by law, our total liability for any claim arising from your use of this site is limited to the greater of USD $50 or the amount you paid us in the 12 months before the claim arose — which, since this site is free to use, is currently $0. Some jurisdictions, including certain US states, Australia, and the EU, do not allow the exclusion or limitation of certain warranties or liabilities, so some of the above limitations may not apply to you. Nothing in these Terms excludes or limits our liability for death or personal injury caused by negligence, or for fraud, where such exclusion would be unlawful.

7. Indemnification

You agree to indemnify and hold [BUSINESS_NAME] harmless from any claim, loss, or damage — including reasonable legal fees — arising from your misuse of this site's estimates or your violation of these Terms.

8. Governing law

These Terms are governed by the law of [JURISDICTION], without regard to its conflict-of-law principles, and any dispute arising from these Terms or your use of the site will be resolved in the courts of [JURISDICTION]. If you are a consumer resident in the EU or UK, you retain any right available to you under applicable consumer protection law to bring proceedings in the courts of your own country of residence.

9. Changes to these terms

We may revise these Terms from time to time. Material changes will be announced via a notice on the site, and your continued use of the site more than 30 days after such notice constitutes acceptance of the revised Terms.
