Made on the Rock

Built by Cascade, for the island we work on.

Who's behind it

Cascade is a Jersey outfit that helps trades on the island get found and get booked.

Websites, enquiries, follow-ups, quotes — the admin half of a trade business that eats your evenings. We work with builders, roofers, sparkies and groundworkers across Jersey, and Graftable started as a tool we made for a couple of them. It worked well enough that keeping it to ourselves felt daft, so it's free for every trade on the Rock.

It stays free. There's no card, no paid tier behind the curtain, and the tool doesn't get worse if Cascade never hears from you.

If you make an account and look like a trade we could help, we may get in touch once. Nothing more than that — see the privacy notice for exactly what we hold and how to opt out.

Where the weather comes from

Forecast data is supplied by WeatherAPI.com. Graftable doesn't forecast anything itself — it reads their numbers against the working limits for your trade and turns them into a verdict.

Weather forecasts are probabilistic: they describe what is likely, not what will happen. They can be wrong, and they should never be the only thing you rely on for a decision that affects someone's safety.

A guide, not a guarantee

Graftable is a planning tool. It is not a safety system, and it does not replace a risk assessment, a method statement, or the judgement of whoever is stood on the site. Every verdict shows the reasons behind it precisely so you can look at it and overrule it.

You stay responsible for deciding whether work goes ahead and for the safety of anyone doing it. If your own eyes disagree with Graftable, back your eyes. Full terms are on the terms page.
