What our customers have to say

“Wow, what a great experience we had having Dean and his competent team of tradesmen transform our 1960’s home in to a modern, large home that caters the family’s needs.
After consulting with a number of builders, Dean came in, problem solving rather than telling us what we can’t do.
My husband (a tradie) was very impressed with the solutions and troubleshooting Dean and the team came up with, as well as the consultation along the way.
We were informed each week exactly what would be happening the following week. I was impressed with the punctuality, if they said they’d be here, they were! They were respectful of being in our home, cleaned up every day and were fabulous at minimising disruption to our household.
Dean coordinated everything for us. When we thought there was a minor issue with the hot water install, he had his team here the next day, (issue was gas from street, nothing to do with job).””We were so impressed with Dean and the team, we added to our job with another bathroom and extensive landscaping. We have already recommended Dean to friends and will continue to do so. Best of all, the cost was very reasonable, he gave us a time frame and it was completed on time, on budget! Thank you Dean and Team BDC.”
Kelly & Mark Judd”“We first engaged the guys at Black Diamond Constructions back in 2015 for the construction of our Granny flat and pool.

We where so impressed with the final product they where the natural choice to complete the build of our home a few years later.

This involved the near complete demolition of our home with only part of the ground floor frame left remaining. As we wanted to complete some of the works ourselves this was done on a cost plus basis.

During this build we found the entire team to be reliable, trustworthy and honest.

The end result speaks for itself and we would have no hesitation in recommending Dean and his team.”
Dave”“We had the absolute pleasure of building with Black Diamond Constructions on our recent first floor extension.
Dean and the team were always friendly, respectful and professional.
They worked around/with us as we remained in the house during construction.
We wanted a builder who could offer suggestions and ideas to improve our vision and Dean never disappointed!
We highly recommend Black Diamond, they did an amazing job on our build! We absolutely love the end result and can’t imagine working with anyone else.”
Emma B.“Dean and the team did an amazing job of our first floor extension, he kept us up to date each day with what was happening around the place and what was coming next. The time that was allocated for the job was spot on and the team were always professional.”
Suz S.“We completed a large renovation on our house with Black Diamond Construction.
Dean went above and beyond to achieve exactly the finishes that we were after.

Dean and his team were reliable, tidy, polite, with great workmanship and attention to detail.

Thanks to Black Diamond Construction our house was totally transformed and I couldn’t recommend them more highly.”
Leon M.“I’d highly recommend Dean and his team. He always kept us in the loop with where they were up to, before and during construction. Their attention to detail gave us a great finish on budget. Thanks.”

Ryan A.“Dean and his team did an amazing job to make our home beautiful.
We are so happy with the work they have done and everyone that comes over can not believe the transformation. It really has been our dream come true.
We lived in our house during renovations which was a little tricky at times but Dean always made sure the kids and even the dog were happy and comfortable.
Highly recommended.”

Kylie N.“My wife and I couldn’t recommend Dean and his team of tradesmen more highly. BD Constructions were not only price competitive, but Dean went out of his way to offer options and alternatives to improve the build. When any issues arose, as is inevitable with construction, Dean sought to solve these in the most cost effective manner and always maintained a highly professional approach. He has selected tradesmen that are not only proficient in completing a quality build, but also conduct themselves in a friendly and approachable manner. Many thanks for a successful build.”

Benjamin H.“Dean and his crew have been excellent throughout our five month build. They finished on schedule and Dean communicated every step of the way. He had plenty of ideas and solutions to any problems that popped up and offered us the option to do certain things ourselves if we wanted to save a buck here and there.
Their standard of work and materials is very high and they ensured everything was done properly and corners weren’t cut.
All nice guys who work like champions.
Thanks heaps Black Diamond Constructions.”

Adam M.“Great job, excellent service. We had a large extension built on slab, no problems during construction, great team. Highly recommend. Very happy with our new extension.”
