Plastering- 7 Nov 2017
Bernie provides outstanding customer service. He takes great pride in his works and has a large understanding of skills that he is more than happy to share. He worked extremely well on leveling the fireplace to the correct height and the job was done in great timing. He had great availability for the job and I was so pleased that it was done urgently. He showed me some of his other works and it was a truly magnificent work of art to say the least and I would highly recommend him to friends and family.

Based on my experience I have no hesitation recommending BCB Building Services who came recommended to me prior to this work by word of mouth. I needed to carry out modest renovation and remediation works on a newly purchased period property requiring many trades; general builder, scaffolder, plumber, plasterer, roofer, landscaper and damp specialist, etc. Brad and BCB team promptly provided a quote and, essential for me, agreed to source and project manage the diverse trades required to complete the work. They are busy but worth the patience and short wait necessary to get the work done by them. The workforce were professional, tidy, courteous and organised minimising disruption during the works and leaving the house clean and undamaged in their wake. The works were delivered per schedule and to a high standard and whilst not the cheapest, the pricing is fair and I believe the outcome represents tremendous value. Brad and the team remained pro-active beyond works completion and engaged actively in addressing the small amount of trivial snagging. They are now my go to for building works.

I particularly impressed with how they complete the job in a timely manner. All the materials that have been used are of great quality; and it shows.

Extensions- 22 Dec 2025
We contracted JMD for a detached house project to demolish an old 1970s extension & rebuild larger 70sqm extension, an outside terrace patio and remodel some of our internal ground floor setup. Project started in Feb2025 and JMD made super quick progress on the build during the dry spring months. We had to pause JMD due to our timelines which they were fine with and finally completed end-to-end by Oct2025. What makes JMD standout for us was their team of employees – they don’t use too many contractors, most of their team are employed by JMD and are a loyal hardworking professional squad. Liam, Mark, Chip, Ross, Zac and the rest – all top class! We had some additional projects and requirements mid-project, JMD provided good pricing along the way which were all totally fair and priced as incremental add-ons. YES – there are always bits that could be better, but JMD did an excellent job on the whole. Site left clean, tidy, complete and all post project snags dealt with! THANKS JMD!

Extensions- 2 May 2019
I would like to say that Danny and his team did a fantastic job on the single storey extension to our home, they were very efficient and tidy during the whole build and kept us informed at each stage. I was very impressed with the speed in which it was completed, and the building inspector also commented on how much of a good job it was. Danny is very approachable and informative and added some really nice touches to the extension after consulting us which gave it that bit extra! some of his ideas I wouldn’t have thought of, I would not hesitate to recommend Danny, we are very happy and looking forward to appreciating their hard work.
