Terms of Use

By using GarageDoorCalcs.com you agree to these terms.

1. Service

GarageDoorCalcs provides free, informational garage-door cost, sizing and hardware calculators and reference content. Use requires no account.

2. Estimates only — not professional advice

All results are deterministic estimates computed from the inputs and prices you provide and standard reference conventions. They are for planning and education and are not a bid, a contract, a repair procedure, a structural/engineering determination, a code-compliance certificate, or safety advice. Get itemized written quotes from licensed, insured garage-door installers. ⚠️ Garage-door torsion and extension springs and cables store extreme mechanical energy and can cause serious injury or death — spring, cable and off-track work is for a trained garage-door technician with the correct winding bars, never DIY. Hard-wired opener circuits are for a licensed electrician; rough-opening and clearance values are labeled planning typicals, not a structural design.

3. No warranty

The site is provided "as is" without warranties of any kind. While the formulas are tested against known values, we do not guarantee that any result fits your specific situation. You are responsible for verifying figures and measurements before relying on them.

4. Limitation of liability

To the extent permitted by law, Redbit S.r.l.s. is not liable for any damage arising from use of the site or reliance on its results.

5. Intellectual property

Content and design are protected. You may use the calculators for personal and professional purposes; you may not copy the site's content wholesale.

6. Provider

Redbit S.r.l.s., Viale della Grande Muraglia 494, 00144 Rome, Italy (VAT IT15237911001). Contact: [email protected].
