10/10
Mario renovated our kitchen and did an amazing job!! Great service, professional and great communication. Highly recommend!!!
I can’t recommend Mario and Optiflow highly enough. I needed an emergency job done on my blocked drains and Mario organised to be here within 2 hours. He went above and beyond to clear all the drain pipes and have us up and running very quickly. Polite and helpful customer service that was second to none.
Mario and Optiflow truly deserve 5 stars. He has been incredibly helpful from the beginning as we had a major plumbing issue to deal with. The fact that he takes the time to explain the solution to his clients irrespective of how many questions you ask or what time you call is testament to his customer-centric approach. Amongst a sea of dodgy plumbers and shady workmanship, it is refreshing to see someone who is actually willing to help those clients that are in need of his services. If you’re looking for someone else – don’t. Mario is your guy.
I reached out about a water leak and got a super quick response. The plumber was professional, helpful, and guided me through the fix right away. Really appreciated the fast support and clear advice. Highly recommend!
Very helpful in explaining what was going on and know what they’re doing.
Mario came out and unclogged the kitchen sink quickly and efficiently. He was fast, reliable and reasonably priced.
Would definitely recommend!
The quality of work I’ve seen from the blokes at Optiflow is unmatched! They are phenomenal guys who take pride in their work and genuinely care about their customers!
Mario was punctual, quick and honest. Everything you want in a tradesman. we are super please with the service provided by the optiflow team.

Helpful explanation was provided as well.
