One to be careful with is the electrician Ben. The work seems alright, but his advise left us with excessive lighting in Kitchen and sitting room and our decision against TV sockets in ALL rooms was interpreted as NO TV and phone socket at all, which then later had to be added at extra cost and left the choice of suppliers limited. His crew also did the plumbing and the bathroom installation and the later was not done to the general standard of U&U constructions work.

We used TAC Building for a full bathroom renovation. From the moment we met Tom, we were really impressed with his knowledge and experience in the industry. Our bathroom looks amazing, and his whole team worked really hard every day. The quality of the finish and the attention to detail are things that you only find in high end tradespeople, and he is definitely one of those. We have used Tom for other jobs since, and will again in the future. Thank you Tom.

Gaby is great and I strongly recommend him. I found him to be extremely reliable, exceptionally capable, a very tidy and clean workman, honest, fair and very reasonable in his costings. I also think that he can turn his hand to a lot of different jobs. Gaby installed complicated stair handrails on three floors and did a terrific job.
