Are ground screws guaranteed?
We do not offer a formal written guarantee, and we would encourage caution toward any installer who makes blanket guarantee claims without qualification. What we do offer is: screws manufactured to EN1090-2 and galvanized to EN ISO 1461, installation using the correct specialist machinery, a proper site assessment before and during the job, and a sign-off with the customer at the end. We install to specification, we over-specify where sensible, and we stand behind our work.
What happens if you hit something underground?
Before any installation, we use radar, cable and utility scanning equipment to check for underground services. If we encounter an obstruction — buried concrete, utility services, large roots, or ground conditions that prevent a screw being driven — we will not charge for that position. We will advise on the best alternative for that location. We also recommend that customers notify their utility provider and mark any known services before our visit.
Are ground screws suitable for my project?
Ground screws are suitable for the majority of garden rooms, cabins, decking, timber structures and similar outdoor buildings on standard residential ground. They perform reliably across clay, loam, sandy soil and most standard South East England ground types. We can advise on the right screw length and spacing for your project. For very unusual ground conditions, unusually heavy structures, or sites with significant access limitations, we will tell you upfront if a different foundation approach is more appropriate.
Do you check for underground cables or services?
Yes. We carry and use radar, cable and utility scanning equipment before every installation. This does not replace your responsibility to check with your utility provider and mark any known services before we arrive — we ask all customers to do this. If we identify a potential conflict on site, we will stop and discuss the best approach before proceeding.
Are ground screws better than concrete?
For most residential garden room and outdoor structure applications, yes. Ground screws require no excavation and produce no spoil, involve no concrete or cure time, and allow you to start building on the same day. There are no concerns about slab settlement or cracking over time. The installation is faster, cleaner and causes less disruption to the garden than a poured concrete base. For the majority of projects we work on, ground screws are the practical, cleaner and faster choice. Concrete may still be appropriate for certain specialist structures or unusual ground conditions, and we will always give you an honest assessment before you book.
Do you work on domestic projects or just trade?
Both. Most of our regular work is for garden room companies and trade customers, but domestic installations are welcome. If you are a homeowner having a garden room, cabin or outdoor structure installed and you want ground screws professionally installed, we can help.
