What Our Clients Say
Ben May The team was able to help me with my retrospective certification, going above and beyond. To get the job done on a tight timeline Chris Stimson (stimooo) David provided extremely valuable advice regarding an approval we were looking to obtain. Very professional and would highly recommend Louise Cullen After years of pain dealing with our local council on our build, David quickly and painlessly provided a path to final certification. Could not be happier with the straightforward, professional service David provided. I would 100 percent recommend him for certification challenges. sherif zedan David provided excellent advice on a renovated house we are offering to buy and helped us identify how to confirm that the seller had the required approvals. His expertise and attention to detail gave us peace of mind. Highly recommend him for any building certification needs! Ambrose McCullagh David's consultation helped bring together disparate information on the process and pitfalls of getting approval for renovations completed by a previous owner. Nicolás Guerrero I couldn’t recommend QRBS enough. I purchased a 1990s house that didn’t have a final inspection certificate. I called multiple certifiers and most of them didn’t even want to take on the job. David has specialised in this matter and we couldn’t have gotten our final inspection certificate without his expertise. Jeremy Duff I contacted David to gain advice on the retrospective building approval process for a post war home. He provided me honest and frank advice that allowed me to make an informed decision and understand the risk associated with leaving the works as is. I highly recommend his services for those looking understand the risk associated with historical unapproved works on your home. Gautham David provided excellent consultation regarding retrospective approval for unapproved structures. His expertise and clear guidance helped me understand the process thoroughly, and his practical advice was invaluable. Melissa Burow They have us great advise involving retrospective approval. Highly recommend Lindsay Harris Incredibly helpful! Special mention to David, he knows what he's talking about... providing guidance and advice that has saved my time and money.
