Terms of Use

• Information only: AmmoniaCrews lists contractors from information they publish. We try to keep it accurate and show when each listing was last checked, but details can change, so confirm qualifications, licensing, insurance and availability directly with the contractor before hiring.
• No endorsement: a listing is not an endorsement, certification or recommendation, and we don't rank contractors.
• Third-party sites: links lead to websites we don't control.
• Your agreements are your own: any work, quote or contract is between you and the contractor.
• Use of the site: please don't scrape the site in a way that disrupts it, and don't misrepresent its content.
• Corrections: see Contact.
• Changes: we may update these terms, and the date below will change.
