Bricklaying- 26 Oct 2025
Elliot and Paul did a great job of designing and building our garden wall with step and pillar (12m x ~90cm). They worked solidly over several days, reliably arriving early every morning despite the distance and cleaning up effectively. Elliot was exceptionally responsive and approachable. I can thoroughly recommend this business based on the work done and how it was carried out.

Extensions- 22 Aug 2022
Jagdeep and his team have been great. He is very polite and throughout the whole project we got along very well. He has done a great job for the complete project. I have asked him to come back to more and more work. It started off with a 16m2 bungalow, then 60m2 driveway then another 60m2 porcelain patio with stainless handrails. He has built the bungalow extension with complex steels. His brick work is fantastic, all the other brickys have said the work looks very good. He is was good keeping to our agreed price, and when I have asked him to do extra work his pricing has been very honest. If I ever have another project like this again, I would choose Jagdeep again.
