I have known John Dunn from JDBA Certifiers for over 20 years.  I use and recommend JDBA Certifiers professionally because I am confident in their advice and common sense.  They have good instincts towards the design and construction industry.  Their knowledge and experience always come to the fore and they provide a very professional service.

The JDBA Certifiers (JDBA) team has professionalism as its core value.  The streamlined process from the initial consultation, administration, onsite visits and finalisation of the certification process makes them a great company to deal with.  Regardless of the size of the project, the JDBA team are always readily available to provide accurate advice when required.  Throughout the construction phase, the JDBA team are very obliging with pro-active advice that keeps us updated with any changes to building legislation.  JDBA’s design and compliance input is exceptional and has always facilitated a trouble free approval at the end of the project.  We now consider JDBA a strategic partner in all of our design and construct projects.

Parish Constructions Pty Ltd would happily recommend the JDBA team to any person looking for an efficient and competent building certifier of choice.

We have been engaging JDBA Certifiers (John Dunn) as our building certifier for 3 years now.  What we like about JDBA’s service is that they have a great knowledge of the building code and compliance and how it relates to our business, they are  always on hand for advice and reassurance when questions need to be asked at all stages of the building process, including early preliminary advice which is fantastic.
