Plastering- 21 Sep 2026
John was quick to respond and came around promptly. Quoted quickly for a reasonable price, and commenced works the following week. Whilst I acknowledge that some of the walls were in very poor condition, there were some that were in very good condition with a decent, flat surface to render. The final result unfortunately was poor, appearing to be a rushed job rather than spending sufficient time ensuring it was completed properly and professionally. Lots of swirl marks in the render and plenty of gouges. Shame really, as the service and communication is otherwise on point.

Bricklaying- 6 Jun 2026
Absolutely fantastic service from start to finish! The team demolished our fallen garage and built a brand-new one to an excellent standard. Communication was brilliant throughout the entire process, keeping us informed every step of the way, and the turnaround time was much quicker than we expected. Everyone we dealt with was friendly, professional, and always happy to answer any questions. The workmanship is outstanding, and we're extremely pleased with the finished result. I wouldn't hesitate to recommend them to anyone looking for a reliable and professional company. A big thank you to Teresa, Jason and the team. Thank you for a job well done!
