From the moment I met Steven I knew I had made the right choice in using him and his services. I found Steven to be very approachable and very knowledgeable with the building industry standards. He was generous with his time onsite, providing me with a very detailed building report, which the clients received. I have no hesitation in recommending Steven or his services to any future clients.

Thank you again for your prompt response

Steven was a complete professional! He gave me a Quote before the job so I was aware of the price, he was very courteous and polite, and he did his job thoroughly and methodically. I would recommend SJN to everyone I know because they won’t be disappointed.

Steven was very good to deal with, I had referred a client of mine that needed his services, due to a home being newly built by a project builder.  Steven picked up many defects that totalled to approximately 40 items! Without his help, my clients would have moved into their brand new home facing problem after problem. Thanks to SJN, all items were rectified by the builder prior to occupation.


They rang quickly to book the job and kept me in the loop all the way. They were efficient, which was a bonus point and I was pretty impressed with their service.
