Driveways (Paved & Loose)- 6 Jul 2026
Jeromy and his team did a fantastic job on my new driveway. They arrived on time, worked efficiently, and kept everything tidy throughout. The finish is neat, durable, and exactly what we agreed. Great communication, fair pricing, and reliable service. I’d highly recommend Jeromy to anyone looking for a trustworthy builder.

Bricklaying- 17 Dec 2024
They initially gave a fair price and a date and timeline that fitted with our needs. Subsequently they over ordered on the bricks so we had over 100+ expensive London bricks left over and they under ordered on sand and cement.(Luckily the shop took them back but we had to deliver them there) The job took far longer than they had said although the poor weather did not help much which could not be helped. The worst was that the wall was finished so that the latch of the gate could not be fitted as the wall was a bit too long! The wall looks good but their customer service and time given for job as well as ordering materials needs some improvements. They are pleasant workers, not rude in speaking
