Bricklaying- 23 Oct 2018
Tony and his team were phenomenal! Professional, courteous, reliable, tidy and quick. Tony's communication throughout the build was consistent, clear and precise. Tony really listened to me throughout the process; provided advice and options but most of all completed the project the way I needed it. The whole build went exceptionally smoothly, was finished ahead of schedule and on budget. Tony's workmanship is excellent and the final finish spot on. I was really worried about finding the right builder for my project... I simply could not have found better. I got several quotes from different providers and Tony's represented the best value for money. I highly recommend Lto builders, you will not be disappointed.
