Carpentry- 25 Jun 2026
I cannot recommend Liiam highly enough. Before I had even hired him, he went out of his way to sketch up two different design options so I could visualise the finished result. I purchased the balustrade kit through a third-party supplier, and Liiam even took the time to recover my basket and help ensure I had everything needed. He arrived exactly when he said he would, worked incredibly tidily throughout, and his attention to detail was outstanding. Most importantly, the finished balustrade looks absolutely fantastic and has transformed the space. Liiam clearly takes great pride in his work, and it shows in the quality of the finished job. Professional, reliable, meticulous, and a pleasure to deal with from start to finish. I would wholeheartedly recommend him to anyone looking for a skilled and trustworthy installer.

Hi, Dan recently completed a loft conversion and ground floor extension for our house in Ealing. It is the second time I've used him for a loft conversion. We are delighted with the work, team, price and timing and I highly recommend him. Dan is entirely trustworthy, and the team are a mixture of his family, friends and choir group. Like all projects there were a few snags and without fail Dan was pragmatic, helpful and keen to make sure we were happy with the quality at the end. I've recommended him to neighbours on both sides who are both pleased and happy to recommend him.
