Terms of Use

Use DeckCalc as a planning estimate—not a final design

By using DeckCalc, you acknowledge that its outputs are informational estimates and must be independently checked before purchasing materials or beginning construction.

Last updated: July 30, 2026

Estimates only

DeckCalc calculations are planning estimates based on the measurements, options, prices, assumptions, formulas, and rounding rules used by the tool. Actual quantities, costs, availability, waste, labour, taxes, and site conditions may differ.

No structural or engineering advice

DeckCalc does not provide structural design, engineering, architectural, surveying, inspection, legal, safety, permitting, or building-code advice. It does not confirm that a deck design is safe, compliant, buildable, or suitable for a particular property.

Your responsibility

You are responsible for checking all measurements, quantities, spans, loads, materials, fasteners, connections, foundations, railings, stairs, local codes, permits, utility locations, and manufacturer instructions. Consult qualified professionals and local authorities when appropriate.

Prices and third-party information

Any prices or external information used with the calculator may be incomplete, outdated, location-specific, or entered by the user. Verify supplier pricing, taxes, delivery charges, and product availability before making a purchase.

Availability and changes

DeckCalc may update, remove, or change features without notice. The website may occasionally be unavailable or may not work correctly on every browser, device, or network.

No warranty

The website and calculator are provided on an "as available" basis without a guarantee that every result will be accurate, complete, current, or suitable for your project.

Limitation of responsibility

To the extent permitted by applicable law, DeckCalc is not responsible for losses, costs, injuries, delays, purchasing decisions, construction errors, or other consequences arising from reliance on calculator outputs or website availability.
