What our clients say
"
Diagnostech were engaged by the owners corporation to investigate the cause of the water ingress affecting several apartments and provide recommendation for remedial repairs. David Chan has been an amazing engineer to work with, taking the time to explain in layman terms the cause of the fault, how the water enters the building and metholdology for repairs to comply with the legal requirements.
I have had the pleasure of working with Diagnostech on our current live project, and I can’t speak highly enough about the experience! From start to finish, their professionalism, expertise, and attention to detail were exceptional. Swahil Patil, Theriza and Raj took the time to thoroughly assess the complex issues and address them to ensure full compliance. Their wealth of knowledge is impeccable.
I highly recommend Diagnostech for any remedial engineering work. It’s rare to find someone so reliable and skilled, and I will definitely be reaching out for any future needs!
Thank you again for the fantastic service!
What I find probably the most valuable thing about working with Diagnostech is that I really trust their advice and they have a very practical application to what we do and they understand our clients’ needs and just the way they deliver, they understand it.
Diagnostech have been in the market for over 20 years. They’ve worked across a lot of buildings across Sydney and so they really have the know-how, technical knowledge and the ability to explain in layman’s terms to lay people, which is very valuable. Dennis truly is the most honest, integrity-driven building consultant out there.
I enjoy working with Diagnostech because they have a detailed knowledge about buildings. Diagnostech are the experts and I know when I speak to them I can understand if what the client is seeking is relevant and they can provide the appropriate recommendation about how to handle a problem.
We have enjoyed worked with Swahil & the team for the last year & would highly recommend them to anyone requiring façade engineering services on their project.
