About us
Built on Better Foundations.
Grand Screw Co. was founded by tradespeople who were tired of waiting for concrete to cure. There had to be a better way — and there is.
Our story
We started Grand Screw Co. after years of working on construction projects where concrete foundations caused delays, disruption, and unnecessary cost. Ground screws changed everything for us — and we've been installing them ever since.
Today we work with homeowners, builders, and contractors across the region, delivering fast, clean, and reliable ground screw foundations for every kind of project. From a single garden room to a large solar array, we bring the same level of care and precision to every job.
We're proud to be certified installers of RADIX Ground Screws — the UK's most trusted ground screw system — and we back every installation with a full specification report and post-installation support.

We'll tell you if ground screws aren't right for your project. We'd rather lose a job than give you the wrong solution.

We leave your site exactly as we found it — no spoil, no mess, no damage to your garden or driveway.
On time, every time
We know your builder is waiting. We schedule carefully and show up when we say we will.
