“ Really, really good with their communication
It has totally transformed the way we live here. For me, the incredibly important thing during a build is the communication between builder and owner. That communication was key. The contractors that Addbuild used were fantastic. Again, really, really good with their communication."
“ I love it!
No build is perfect and you always have challenges along the way, and I think it’s how a company deals with those challenges that gives you the trust to be able to use them again and recommend them to others. So for me, I think Addbuild has proven they can do that."
“ We’ve already recommended Addbuild to others
Their consultation prior to any financial commitments was really very thorough, and they were willing to put in a lot of time and effort. So we were really pleased with that process. We’ve already recommended Addbuild to others."
“ It was a really seamless project
Very positive... There were issues along the way but Addbuild addressed them very quickly. Our supervisor John was fantastic. Every time I'd call him or message him, he'd message or call right back... The kids are loving it, they've got their own space and everyone's happy."
“ We definitely had the A team and are very, very happy with the result
I just wanted to say thank you for your help and a big thanks to Emmory, John, Arthur, Adrian, Marco, Chris and Stuart and all the tradies. Thanks everyone! Very smooth and supportive process with high attention to detail. We were so happy with John leading the team, he is so knowledgeable and has great vision, so happy to have him helping us through this process."
“ We have previously renovated with Addbuild
We are a return customer because of the professionalism and results the first time around. We have really enjoyed having the team back and the quality of the work they do. From Jack, John and Joey getting the lock-up sorted, to Adrian and Pete doing the bits and bobs and some familiar trades from last time along the way, they have produced the result we have been imagining for so long!"
