We wanted to add an ensuite to our downstairs bedroom and it wasn’t a straightforward knock down renovation, but George was very professional and listened to our needs as a customer. The company, tradesmen and other professionals were great and very accomodating. Although the project took a lil longer than anticipated we were left with smiles at the end. They did a great job👌🏼 Definitely an added asset to our home. Thanks again GSCPosted on Google![]()

I have engaged George to perform inspections of new house build. We faced multiple issues with build but George was able to make me understand of the issues and provided sound advice through the process. He is very knowledgeable, professional in his dealings and prompt. The only regret I had was, I wish I have engaged him on staged inspections from day 1 of the build!Posted on Google![]()

From my first meeting with George I thought he was honest and fair. I chose his company to handle some bathroom and laundry renovations and I was not disappointed. The work was completed on time to a high standard. All through the project George kept me informed of timings and progress. He had a good understanding of what I wanted and what I was trying to achieve. I would not hesitate to recommend his company, they were great to deal with. 😀Posted on Google![]()

George is a gentleman, best building inspector in Adelaide and he is the only one I would recommend to our buyers and sellers. He’s genuine and takes the time to sit down with the client and explain his findings.Posted on Google![]()

I recently had GSC Building Consulting and Construction carry out a building and pest inspection for a property I purchased, and I couldn’t be happier with their service. From start to finish, their team was incredibly thorough, professional, and detail-oriented. The inspector took the time to walk me through every aspect of the report, pointing out areas of concern and giving practical advice on maintenance and repairs. Their keen eye for detail gave me confidence in understanding the condition of my new home. The report was well-organized and easy to understand, covering all the essential areas I needed to know about. It was clear they genuinely cared about helping me make an informed decision. Thank you, GSC, for such a positive experience! I highly recommend them to anyone needing a building and pest inspection. Their dedication and expertise are unmatched! ⭐️⭐️⭐️⭐️⭐️Posted on Google![]()

GSC has been fantastic during my bathroom renovations. It seemed a simple job, but there were some hidden issues. George was amazing, kept me informed of every step. He was very thorough, and explained why ‘things’ were happening. He did an amazing job…especially as my place lacked some basic water proofing issues when first built. George explained the process & what needed to be done. I felt like I was continuously in the loop. The renovations ran smoothly & the tradies were very approachable, especially when I had questions. I must say, it was a big job, but it was done properly! I felt reassured 👍 Then we moved on to replacing the living room and hallway flooring…I’m hugely impressed with the end product. Thank you for keeping me informed & also not just doing a touch up job. I was reassured constantly, with updates and what was happening next. If you’re after renovations/building…GSC has been easy to work with. I love my bathroom and new flooring. I highly recommend George (GSC) and his team.Posted on Google![]()

George was very professional and price wise, extremely reasonable. Turned up on time and plenty of notifications was given to keep us informed throughout the process. I highly recommend GSC to anyone that seeks professional building services. Hands down, they are the best!!Posted on Google![]()

George was friendly and responsive to our enquiries for a new build pre- handover inspection. He was willing to travel to Yorke peninsula for this job- of course it was more expensive given travel time - but it has already paid for itself as the builder is required to fix things that would have cost us thousands of dollars. We have had multiple concerns needing rectification with our build and having a building inspector validating our concerns that certain aspects of the build needed repair/ improvement and were not up to industry standard assisted us to communicate to our supervisor in a formalised way. It saved us lots of headaches and angst. Definitely worth it. Thanks George for helping us out. Legend.
