Client Reviews

Don't just take it from us, hear what our clients have to say...

As an owner of a property in Rosanna, my wife and I decided to employ the services of DNJ Building Group to carry out a significant 20+sq extension on our property. These works were carried out professionally on time and to a standard that has no question. DNJ made suggestions that improved the appearance and functionality of the project and for that we are very grateful. I would have no hesitation in recommending DNJ or using them again in the future. Happy building with DNJ – you’re in good hands.

We really appreciate the effort the team at DNJ put into building our new home, especially Damien's honesty and up front approach. He was always understanding, patient, provided an outstanding service and has great attention to detail. DNJ's approach to customer service was fantastic, we were kept informed at every stage of construction. We were initially nervous about building a new home but the process could not have been easier thanks to the whole team. Thank you to everyone at DNJ for your professionalism and high quality workmanship. We would recommend you to anyone wanting a custom home completed to a very high standard.
